Selection Procedure 11
R410A All DC Inverter V4+S Series 50/60Hz MCAC-VTSM-201605

1. Introduction
1.1 Model selection procedure
Select the model and calculate the capacity for each refrigerant system according to the procedure shown
below.
 -conditioning load, Calculate the maximum air-conditioning load for each room
or zone.
Selection of air conditioning system

Design of the control system

Preliminary selection of indoor and outdoor units

Check of the tubing length and level difference
 Check that the length of refrigerant tubing and the elevation difference are within the allowable ranges
Calculation of the corrected outdoor unit capacity
 Capacity correction coefficient for model, outdoor temperature conditions, tubing length and elevation
difference.
Calculation of the actual capacity for each indoor unit
 Calculate the corrected indoor/outdoor capacity ratio, based on the corrected outdoor unit capacity and the
total corrected capacity of all indoor units in the same system.
Recheck of the actual capacity for each indoor unit
 If the capacity is inadequate, reexamine the unit combinations.
1.2 Indoor unit selection
Enter INDOOR UNIT CAPACITY TABLES at given indoor and outdoor temperature. Select the unit with the
nearest greater capacity to the given load.
Note:
Individual indoor unit capacity is affected by ODU selection. Actual capacity has to be calculated according to the outdoor unit
capacity table.
Calculation of actual capacity of indoor unit
Because the capacity of a multi air-conditioner system changes according to the temperature conditions,
tubing length, elevation difference and other factors, select the correct model after taking into account the
various correction values. When selecting the model, calculate the corrected capacities of the outdoor unit and
each indoor unit. Use the corrected outdoor unit capacity and the total corrected capacity of all the indoor units
to calculate the actual final capacity of each indoor unit.
Find the indoor unit capacity correction coefficient for the following items:
 Capacity correction for the indoor unit temperature conditions
From the graph of capacity characteristics, use the indoor temperature to find the capacity correction
coefficient.
 Capacity distribution ratio based on the indoor unit tubing length and elevation difference.
First, in the same way as for the outdoor unit, use the tubing length and elevation difference for each indoor
unit to find the correction coefficient from the graph of capacity change characteristics
Capacity distribution ratio for each indoor unit=Correction coefficient for that indoor unit / Correction coefficient for the
outdoor unit
1.3 Outdoor unit selection
Allowable combinations are indicated in INDOOR UNIT COMBINATION TOTAL CAPACITY INDEX TABLE.
In general, outdoor units should be selected by the following factors, the location of the unit, zoning and usage

12 Selection Procedure
MCAC-VTSM-201605 R410A All DC Inverter V4+S Series 50/60Hz
of the rooms.
The indoor and outdoor unit combination is determined that the sum of indoor unit capacity index is nearest to
and smaller than the capacity index at 100% combination ratio of each outdoor unit. Up to 13~36 indoor units
can be connected to one outdoor unit. It is recommended to choose a larger outdoor unit if the installation
space is large enough.
If the combination ratio is greater than 100%, the indoor unit selection shall be reviewed by using actual
capacity of each indoor unit.

2.2 × 1 +2.8 × 1+ 3.6 × 1 +4.5 × 1+ 5.6 × 1 + 7.1 × 1 = 25.8kW (88000Btu/h)
 Select outdoor unit: MDV-280(10)W/D2RN1(B) which has nominal cooling capacity: 28kW (95500Btu/h).
 Calculate the proportion: 258/280= 92%
2) Result: Because the proportion is within 50～130%, it is a suitable selection.
Real function data with indoor unit combination
 For the 92% combination, calculate the cooling capacity of outdoor unit MDV-280(10)W/D2RN1(B):
26.8kW(91440Btu/h)←90% (Indoor temperature: WB 20°C(68°F), Outdoor temperature: DB 35°C(95°F))
28.3kW(96560Btu/h)←100% (Indoor temperature: WB 20°C(68°F), Outdoor temperature: DB 35°C(95°F))
Selection Procedure 15
R410A All DC Inverter V4+S Series 50/60Hz MCAC-VTSM-201605
Then calculate the outdoor capacity in 92% combination index: 26.8+{(28.3-26.8)/10}×2=27.1kW(92470Btu/h);
 Capacity modification coefficient with pipe length 50m(164ft) and height difference 30m(98.4ft): 0.958
 Each indoor unit cooling capacity
Room A: MDV-D22T2 (27.1×22/258×0.958=2.21kW) (92470×7510/88000×0.958=7540Btu/h)
Room B: MDV-D28T2 (27.1×28/258×0.958=2.82kW) (92470×9550/88000×0.958=9620Btu/h)
Room C: MDV-D36T2 (27.1×36/258×0.958=3.62kW) (92470×12300/88000×0.958=12350Btu/h)
Room D: MDV-D45T2 (27.1×45/258×0.958=4.53kW) (92470×15400/88000×0.958 =15460Btu/h)
Room E: MDV-D56T2 (27.1×56/258×0.958=5.64kW) (92470×19110/88000×0.958=19250Btu/h)
Room F: MDV-D71T2 (27.1×71/258×0.958=7.14kW) (92470×24200/88000×0.958=24360Btu/h)

2.4 Conclusion
Generally, this result is acceptable, therefore the calculation process has been completed. But if it appears that
the result is not acceptable, the above process may be repeated.
Remark: In this sample, other capacity modification indexes were not considered and are assumed as 1.0.

Key components:
Oil separator: It is used to separate oil from high pressure and high temperature gas refrigerant, which is
pumped out from compressor. The separation efficiency is up to 99%, it makes the oil return back to each
compressor very soon.
Gas-liquid separator: It is used to store the liquid refrigerant and oil; it can protect the compressor from liquid
hammering.
EXV (Electronic Expansion Valve): It is used to adjust refrigerant volume.
Four-way valve ST1: Closed in cooling mode and open in heating mode. The four-way valve is used to
change the refrigerant flow direction in heating mode. When the ST1 is OFF, the heat exchanger functions as a
condenser. When the ST1 is ON, the heat exchanger functions as an evaporator.
SV2: It is used to protect the compressor. When any compressor discharge temperature is higher than 100oC,
SV2 will be open and spray a small amount of liquid refrigerant to cooling compressor, and it will be closed
when the discharge temperature is lower than 90oC.
SV4: Oil return valve. Opens after the inverter compressor has run for 5 minutes and will close 15 minutes later
(for single outdoor unit system).
Every 20 minutes, the SV4 of each outdoor unit will open for 3 minutes (for multiple outdoor unit system).
SV5: It is used for fast defrosting. In defrosting mode, the opening of SV5 can shorten the refrigerant flowing
circle, so the defrosting process will takes less time. In cooling mode, it is always off.
SV6: It is used for by-pass. Open when the discharge temperature is over-high in cooling mode, and close
when the unit is standby or system is in heating mode.
Pressure switch: It is used to protect the system pressure. When the system pressure is too high or too low,
the pressure switch will open. Once the pressure switch is open, the compressor will stop, and the compressor
will restart after ten minutes.

Unit: mm(in.)
Note: The key points for base:
 The master unit’s base must be made on solid concrete ground. Refer to the structure diagram to make concrete base, or
make after field measurements.
 In order to ensure contact points are equally secure, the base should be completely level.
 If the base is placed on a roof, the detritus layer isn’t needed, but the concrete surface must be flat. The standard concrete
mixture ratio is cement 1/ sand 2/ carpolite 4, and adds Φ3/8inch(10mm) strengthen reinforcing steel bar, the surface of the
cement and sand plasm must be flat, border of the basement must be chamfer angle.
 Before construct the unit base, please ensure the base is directly supporting the rear and front folding edges of the bottom
panel vertically, for the reason of these edges are the actual supported sites to the unit.
 In order to drain off the seeper around the equipment, a discharge ditch must be setup around the basement.
 Please check the affordability of the roofing to ensure the load capacity.
 When piping from the bottom of the unit, the base height should be no less than 7-7/8inch(200mm).

Note:
Before installing the ventilation assembly, please remove the steel mesh, otherwise, the air supply volume will
be affected.
1. Adding shutters decreases air supply, as well as cooling/heating capacity and energy efficiency. This effect
is increased as shutter angle increases. Installing additional shutters is not recommended. If additional
shutters are necessary, shutter angle should not be greater than 15 degrees.
2. The bending place at ventilated duct should be not more than 1(show in above figure), in order to avoid
operation malfunction..
3. Install the flexible connector between the unit and the air deflector pipe to avoid vibration noise.

Caution: Removing oil from copper pipe of a system that uses R410A
For the system that uses R410A, oil-free copper pipes should be selected (they can also be customized). If ordinary (oily) copper
pipes are used, it must be cleaned with gauze that is dipped into tetrachloroethylene solution.
Purpose of cleaning copper pipe: Remove the lubrication (industrial oil used during the processing of the copper pipe) attached to
the inner wall of the copper pipe. The ingredients of such lubricants are different from those of the lubricants used by the R410A
refrigerant, and will leave deposits in the system, which may cause complex system errors.
Special Note: Never use CCl4 for pipe cleansing and flushing, or the system will be seriously damaged.
4.1.3 Support for refrigerant pipe
1. Fixing horizontal pipe
When the air conditioner is running, the refrigerant pipe will deform (for example, shrunk/expanded or droop).
To avoid pipe damage, use hangers or supports (see the table below for the criteria).
Pipe Diameter in.(mm) Less than Ф25/32(20) Ф25/32~1-37/64(20-40) Larger than Ф1-37/64(40)
Interval between support points ft.(m) 3.28(1) 4.92(1.5) 6.56(2)
In general, gas pipe and liquid pipe should be suspended in parallel, and the interval between support points
should be selected according to the diameter of the gas pipe. The temperature of the flowing refrigerant will
change according to operation and working conditions, which will result in expansion and shrinkage of the
refrigerant piping, therefore piping with thermal insulation should not be clamped tightly, in order to avoid any
rupturing of the copper piping as a result of unnecessary stress.
2. Fixing vertical piping
Fix the pipe along the wall according to the pipeline route. Round log should be used at the pipe clip to replace
thermal insulation material, ―U‖-shape pipe should be fixed outside the round log, and the round log should be
provided with anticorrosion treatment.
Pipe Diameter in.(mm) Less than Ф25/32(20) Ф25/32~1-37/64(20-40) Larger than Ф1-37/64(40)
Interval between support points ft.(m) 4.92(1.5) 6.56(2) 8.2(2. 5)

3. Local fixing
To avoid stress resulting from pipe expansion and shrinkage, it is usually required to conduct local fixing
beside the wall through-holes of the branch pipe and end pipe.
4.1.4 Requirements for installing branch pipe subassembly
When laying the branch pipe subassembly, pay attention to the following:
1) Do not replace branch pipe with tee pipe.
2) Follow the construction drawing and installation instructions to confirm the branch pipe models as well as
the main pipe and branch pipe.
3) Sharp bends (an angle of 90°) and connection to other branch pipe subassembly are not allowed within
500mm of the branch pipe subassembly.
4) It is best to install the branch pipe subassembly at a place that facilitates welding (if doing so is impossible, it
is recommended to prefabricate the subassembly).
5) Install vertical or horizontal branch joints, and ensure that the horizontal angle is within 10°. Refer to the right
side picture:

U-shaped branching pipe

A direction view

Wrong Correct

10°
10°

Horizontal surface

6) To avoid oil accumulation in the outdoor unit, please install the branching pipes properly.

7) To ensure even distribution of refrigerant, pay attention to the distance between the branch pipe
subassembly and the horizontal straight pipe.
a. Ensure that the distance between the bending point of copper pipe and the horizontal straight pipe section of
the adjacent branch pipe is larger than or equal to 1.64ft.(0.5m).
b. Ensure that the distance between the horizontal straight pipe sections of the two adjacent branch pipes is
larger than or equal to 1.64ft.(0.5m).
c. Ensure that the distance between the branch pipe and the horizontal straight pipe section used to connect
the indoor unit is larger than or equal to 1.64ft.(0.5m).

4.2 Storage and maintenance of copper pipe
4.2.1 Pipe delivery and storage
1. Prevent bending or deforming during the delivery.
2. Seal the openings of the copper pipe with a plug or adhesive tape during the storage.
3. Place the coil upright to avoid compressing deformation due to self-weight.
4. Use wooden support to ensure that the copper pipe is higher than the ground, so as to make the pipe
dust-proof and water-proof.
5. Take dust-proof and water-proof measures at both ends of the pipe.
6. Store piping at a at specified place on the construction site.
4.2.2 Correct to seal the opening
1. There are two ways for opening sealing:
1) Sealing with cover or adhesive tape (suitable for short-term storage)
2) Wielding seal (suitable for long-term storage)
Caution: The openings of the copper pipe must be sealed at all times during construction.
● Method of sealing with cover or adhesive tape
Insert

Copper pipe Cover Use adhesive tape to

twist tightly at the joint

It is recommended to seal the openings of the pipe with both cover and adhesive tape.
● Wielding seal method
2. Attention:
1) When putting the copper pipe through the hole in the wall, dirt can easily enter into the pipe, the pipe orifice
should be sealed.
2) When the copper pipe is placed outside a wall, ensure that no rain water can enter the pipe, particularly
when the pipe is placed upright.
3) Before completing the pipe connection, seal the openings of the pipe with covers.
4) Place the openings of the pipe vertically or horizontally.
5) Before putting the pipe outside the wall, seal the opening of the pipe with a cover.
6) Do not place the pipe directly on the ground, or keep it away from ground friction.
7) If piping on a raining day, remember to seal the openings of the pipe first.
4.3 Processing of copper pipe
4.3.1 Pipe cutting
1. Tool
Use a pipe cutter instead of a saw or cutting machine to cut the pipe.
2. Correct operation procedure:
Rotate the pipe evenly and slowly, and apply even force to it. Cut the pipe off while ensuring that it does not
become deformed.
3. Risks if a saw or cutting machine is used to cut pipe:
Copper shavings will enter the pipe, these particles are difficult to remove and pose a serious risk to the
system if they enter the compressor or block the throttling unit.
4.3.2 Rectify opening of copper pipe
1. Purpose
To shave away any burrs at the opening of the copper pipe, clean the inside of the pipe, and rectify the
opening of the pipe, so as to avoid scratches at the opening to be sealed during flaring.
2. Operation procedure
1) Use a scraper to remove the inner spurs. When doing so, keep the opening of the pipe downwards to avoid
Installation 99
R410A All DC Inverter V54+S Series 50/60Hz MCAC-VTSM-201605
copper shavings from entering the pipe.
2) After the chamfering is completed, use veiling to remove the copper chip out of the pipe.
3) Ensure piping is not scarred, so as to avoid any breaches during flaring.
4) If the pipe end is deformed, cut the end off and then cut the pipe again.
4.3.3 Pipe expansion
1. Purpose: Expand the opening of the pipe so that another copper pipe can be inserted, serves as an
alternative to direct connections and reduces welding spots.
2. Attention: Ensure that the connection part is smooth and even; after cutting the pipe off, remove the inner
spurs.
3. Operation method: Insert the expanding head of the pipe expander into the pipe. After completing pipe
expansion, rotate the copper pipe a few degrees to rectify the straight line mark embedded by the expanding
head.
Brazing welding

4.3.4 Bell-mouthed opening

1. Purpose: Flaring bell-mouthed opening is used for screw thread connection.
2. Attention::
1) Before performing the bell-mouthed opening operation, perform fire annealing for the hard pipe.
2) Use a pipe cutter to cut pipe ensuring even cross sections and avoid refrigerant leakage; do not use a steel
saw or metal cutting device to cut pipe, in order to avoid deformation and prevent shavings from entering the
pipe.
3) Remove burrs carefully to avoid scars on the bell-mouthed opening, which may lead to refrigerant leakage.
4) When connecting pipes, use two spanners (one torque wrench and one non-adjustable spanner).
5) Before conducting opening bell-mouthed, install pipe onto the flaring nut.
6) Use proper torque to tighten the flaring nut..

Cautions:
a. Apply some refrigeration oil onto the inner surface and outer surface of the flared opening, to facilitate the connection or
rotation of the flaring nut, ensure firm connection between the sealing surface and the bearing surface, and avoid pipe bending.
b. Ensure that the flared opening is not cracked or deformed, otherwise it cannot be sealed or, after the system runs for some
time, refrigerant leakage will occur.
4.3.5 Pipe bending
1. Method
1) Manual bending: Suitable for thin copper pipes (Φ1/4‖(6. 35mm)- Φ1/2‖(12. 7mm).
2) Mechanical bending: Suitable in a wide range of copper pipes (Φ1/4‖(6. 35mm)- Φ2-41/64‖(67mm)). Spring
bender, manual bender or electric bender are used.
Purpose: Reduce welding joints and required elbows, and improve engineering quality; save material, no joint
is needed.
2. Caution
1) When bending a copper pipe, ensure that there are no wrinkles or deformation on the inner side of the pipe.
2) When using a spring bender, ensure that the bender is clean before inserting it in the copper pipe.
3) When using a spring bender, ensure that the bending angle does not exceed 90°, otherwise wrinkles will
appear on the inner side of the pipe, and the pipe may crack.
4) Ensure that the pipe does not sink during the bending process; ensure that the cross section of the bending
pipe is larger than 2/3 of the original area, otherwise it cannot be used.

4.4 Brazing
4.4.1 Selecting refrigerant pipe
1. All pipe used shall comply with national or local standards (for example, pipe diameter, material, thickness,
etc.)
2. Specifications: Seamless phosphorus to oxygenate copper pipe
3. It is best to use straight pipe or coil and avoid excessive brazing.
Note: Select the pipes according to the pipe diameters shown below (O—coil, 1/2H—straight pipe)

4.4.2 Nitrogen filling to protect copper pipe during brazing
1. Purpose: Avoid oxide scale formation on the inner wall of the copper pipe caused by high temperature
2. Risks of non-protective welding:
If insufficient nitrogen is charged during brazing, oxides will form on the inner wall of the copper pipe. These
oxides will block the refrigerant system, which will lead to various malfunctions such as compressor burnout,
poor cooling efficiency.
To avoid these problems, charge nitrogen continuously into the refrigerant pipe during brazing, and ensure that
the nitrogen continuously passes through the operating point until the welding is completed and the copper
pipe cools down completely. The diagram for nitrogen charging is shown below.

3. Making nitrogen-charging pipe joint

When welding the pipe joint, connect the nitrogen-charging joint to the pipe fittings to be welded.
The nitrogen-charging joint is shown below:

4. Cautions for welding pipe fittings

1) Adopt transition pipe.
2) Charge nitrogen from the side of the short pipe, because short distance may result in perfectible nitrogen
replacement effect.

Attention:
1) Maintain the nitrogen pressure at around 0.2-0.3kgf/cm²during the welding.
2) Ensure the gas is nitrogen other than oxygen, oxygen will easily leads explosion, so it is forbidden.
3) Use a pressure reducing valve, and maintain the nitrogen pressure at around 0.2kg/ cm².
4) Select a proper position for charging nitrogen.
5) Ensure that the nitrogen passes through the welding spots.
6) If the pipe between the position for charging nitrogen and the welding spot is long, ensure that the nitrogen
is charged for sufficient time so as to discharge all the air from the welding area.
7) After completing the welding, charge the nitrogen continuously until the pipe cools down completely.
8) Try best to conduct welding downwards or horizontally and avoid face-down welding.

4.5 Pipe cleaning
4.5.1 Flushing copper pipe
1. Function: use pressurized gas to flush pipeline (raw material or welded assembly) to remove dust and
moisture. Removing solid foreign material is difficult therefore steps should be taken to protect it during
construction.
2. Purpose
1) Eliminate oxide powder or part oxide layer in copper pipe.
2) Help to clear dirt and humidity out of piping.
3. Risks of not flushing:
If solids or moisture remain in the system serious malfunctions will occur, such as ice blockage, dirt blockage
and compressor jamming.
4.5.2 Flushing procedure
1. Mounting pressure adjusting valve on nitrogen gas cylinder. The applied gas must be nitrogen. If
polytetrafluoro ethylene or carbon dioxide is used, there is risk of condensation. If using oxygen, there is risk of
explosion.
2. Use inflation tube to connect the pressure adjusting valve outlet to the inlet on the liquid pipe side of the
outdoor unit.

3. Use blind plug to block all liquid side copper line connectors (including unit B) soundly, excluding indoor unit
A.
4. Turn on nitrogen gas cylinder valve, and then using the valve gradually pressurize to 5kgf/cm2.
5. Check to ensure nitrogen has passed through the liquid pipe of indoor unit A. Ensure the connector on the
side of indoor unit body has been covered by tape to prevent dirt from entering.
4.5.3 Detailed steps for flushing
1. Use suitable material, such as a bag or cloth, and press it firmly against the main opening on the gas side of
the indoor unit.
2. When pressure increases and hands cannot be held against the opening, suddenly release allowing gas to

104 Installation
MCAC-VTSM-201605 R410A All DC Inverter V4+S Series 50/60Hz
rush out. (flushing for first time).
Repeat above step1 and step 2 to re-flush dirt (flushing multiple times)
3. When flushing, place a piece of white cotton at the pipe opening to check if there is any moisture.
Method of thoroughly drying pipeline is as follows:
1) Use of nitrogen gas to flush the piping until no dirt and moisture remain.
2) Perform vacuum drying operation (see vacuum drying of MDV refrigerant piping for details).
3) Shut down nitrogen main valve.
4) Repeat the above operations to the connected copper pipe of all indoor units.
5) Flushing sequence: when pipeline has been connected to system, flushing sequence is from farthest to
nearest, relative to the main unit, beginning from the farthest pipe opening to the main unit in turn (i.e.
1)-2)-3)-4)-5)-6)).
②

⑥ ⑤ ④ ③ ①
Caution: When flushing one pipe opening, block all other pipe openings which are connected in the same
system.
6) After finishing flushing, seal all openings to prevent dust and moisture from entering.
4.6 Piping connection between outdoor units
All connection pipes between outdoor units should be horizontal, it is not allowed the concave at junction site.
The height of each connection pipe between outdoor units cannot be higher than the refrigerant outlet.

Advantages of correct connection:

1. No back flow.
2. The slope of two pipes can be regulated separately.
Disadvantages of incorrect connection:
1. Drainage interference.
2. If the fluid volume of one side is greater it will flow to areas with less volume, thus creating back flow into
areas of the system with less drainage.
3. Suspender spacing:
In general, horizontal spacing is 0.8m-1m and vertical spacing is 1.5m-2.0m. Each vertical pipe shall be
equipped with not less than two suspenders. Over spacing of suspenders on horizontal piping leads to sagging,
and creates to air resistance.
4. The highest point of drainage piping shall be designed with air hole to ensure that condensation can be
discharged smoothly. The outlet air hole shall face down to prevent dirt entering piping.
5. After finishing connection, conduct water passing test and overflowing water test to check the smoothness of
drainage and ensure there is no leakage..
6. Use appropriate adhesive for thermal insulation materials seam, and then bind with rubber or plastic
adhesive tape. The width of the adhesive tape shall not be less than 50mm to ensure firm hold and prevent
condensation.
7. The air conditioner drainage pipe shall be installed separately with other waste, rainwater and other
drainage piping.
8. The slope of drainage pipe shall be kept above 1/100.

( 1cm/1m)
above 1/100

9. In case 1/100 slope cannot be met, consider using a larger-sized pipe and its diameter to create slope.
Installation 107
R410A All DC Inverter V54+S Series 50/60Hz MCAC-VTSM-201605
10. Merging pipe shall be done from above to the extent possible in order to avoid back flow to the system.
11. The end of drainage pipe shall not directly contact ground.

Caution
1. The drainage pipe diameter shall meet the draining requirement of indoor unit.
2. The outlet air vent cannot be installed near the lifting pump of the indoor unit.
3. Ensure condensation pump can start up and shut down normally by infusing water into the drainage pan of indoor unit and
powering on.
4. All joints shall be firm (particularly PVC pipe).
5. The drainage pipe is not to be set horizontally or at an incline towards the unit, and suspenders shall be used to avoid sagging.
6. Dimension of drainage pipe shall be not less than the connecting mouth size of the indoor units' drainage piping.
7. Work out thermal insulation for drainage pipe to avoid condensation.. Thermal insulation processing shall be continued to the
connecting part of indoor unit.
8. Indoor units with different draining pattern shall not share the same concentrated drainage pipe.
9. Discharge of condensation cannot interfere with the normal activities occupants..
10. As for long drainage piping, suspenders shall be used to ensure 1/100 slope without any sagging in the PVC pipe.
※ The support spacing for horizontal piping is 0.8-1.0mm. If the spacing is too large, it shall produce sagging and air resistance,
while air resistance could seriously influence the smoothness of water flow and cause abnormal water levels. As shown in
following figure:

5.2 Water storing elbow of drainage pipe

For indoor units with high negative pressure at the outlet of drainage pan, the drainage pipe must be equipped
with water storing elbow.
Function of water storing elbow:
When indoor unit is operating, prevents generating negative pressure from causing drainage difficulty or blow
water from air outlet.
Installation of water storing elbow:
1. Install water storing elbow as shown in following figure: H shall be more than 50mm.
2. Install one water storing elbow for each unit.
3. When installing ensure future cleaning is convenient.

5.3.4 Operation process of concentrated drainage
Install indoor unit → connect drainage pipe → water pass test and overflow water test → thermal insulation of
drainage pipe
Caution:
1) Increase drainage point as much as possible and reduce quantity of connected indoor units, to ensure
horizontal main drainage pipe is not too long.
2) Units with drainage pump and natural drainage shall have separate drainage systems..
3) Add two elbows at air outlet, and make sure its mouth faces down to prevent dirt from entering and creating
blockages.

Vent

Gradient of drain pipe should be more than 1/100

5.4 Lifting of drainage pipe (for the unit with lift pump)
Installation of lift pipe
1. When connecting drainage pipe with indoor unit, use pipe clamp shipped with unit to fix. Glue splicing is not
permitted for ensuring convenience in repairing.
2. To ensure 1/100 slope, total lift height of drainage pipe (H) shall depend on indoor unit’s pump, and do not
set vent pipe on the lifting pipe section. After lifting vertically, immediately place down inclined, otherwise it will
cause error operation of switch at water pump. The connecting method is shown as follows:

Installation 109
R410A All DC Inverter V54+S Series 50/60Hz MCAC-VTSM-201605
Note: Air outlet could not be installed on the lifting part; otherwise water shall be discharged to ceiling or could not be discharged.
5.5 Overflow water test and water pass test
5.5.1 Overflow water test
After finishing the construction of drainage pipe system, fill the pipe with water for 24 hours to check for
leakage at joints.
5.5.2 Water pass test
1. Natural drainage mode
Fill condensation pan with above 600ml of water slowly through check port, check drainage outlet for water
discharge.
2. Pump drainage mode
1) Remove water level switch plug, remove water-finding cover and slowly fill condensation pan with about
2000ml of water through water-finding port to avoid touching the drainage pump motor.
2) Power on and let the air conditioner operate in cooling mode. Check operation status of drainage pump, and
then turn on water level switch, check operation sound of pump and transparent hard pipe at drainage outlet to
confirm water is being discharged. (Depending on the length of drainage pipe, water shall be discharged after
about a 1 minute delay.)
3) Stop the operation of air conditioner and return water-finding cover to its original place.
a. After shutting down the air conditioner, wait for three minutes and check for abnormalities. If drainage pipe
was not installed properly, back-flow water will trigger the alarm on the remote control receiver board and
water will return to the condensation pan.
b. Add water until reaching alarm water level, ensure the drainage pump can discharge water in a timely
fashion. If water level does not decline within 3 minutes of reaching the warning level, it will cause shutdown of
unit. When this situation occurs, normal startup shall be carried out after turning off power supply and removing
the accumulated water.
Note: Drain plug at the main condensation pan is used for removing accumulated water when maintaining air conditioner. During
normal operation, the drain should be plugged to prevent leakage.

7. Heat Insulation Engineering
The insulation of refrigerating equipment and piping follows general insulation methods. Insulating shall be
carried out in a manner best suited for selected insulation material.
7.1 Insulation of Refrigerant Piping
7.1.1 Operational procedure of refrigerant piping insulation
Construction of refrigerant pipe → insulation (excluding joints) →air tightness test → joint insulation
Joints: Insulation of welded joints or flanges should be carried out after air tightness is confirmed.
7.1.2 Purpose of refrigerant piping insulation
1. During operation, temperature of gas pipe and liquid pipe will be heated or cooled excessively. Therefore, is
necessary to insulate in order to guarantee unit performance and compressor life span.
2. Gas pipe temperature is very low during cooling. If insulation is insufficient, condensation will form and
cause leakage.
3. Temperature of gas pipe is very high (generally 122-212°F(50-100°C) during heating. Insulation serves as a
necessary protection from burning..
7.1.3 Selection of insulation materials for refrigerant piping
Adopt closed-cell foam insulation materials with a B1 fire resistant rating and over 248°F(120°C) of constant
burning performance.
7.1.4 Thickness of insulation layer

layer (δ) shall be above 25/32―(20mm).
2. In hot and wet environments, the above recommended value shall be doubled.
Note: The outdoor piping shall be protected by metal casing to protect against sunlight, rain, air erosion and
any other potential causes of damage.
7.1.5 Installation and main points of insulation construction
1. Example of incorrect insulation: Gas and liquid piping are insulated together reducing air conditioner
efficiency and effectiveness.
2. Example of correct installation:

112 Installation
MCAC-VTSM-201605 R410A All DC Inverter V4+S Series 50/60Hz
a. Gas and liquid piping are insulated separately..
Note: After gas pipe and liquid pipe are insulated separately, Do not bind to tightly as the spliced insulation
joint will be damaged.
b. All pipe joints shall be insulated.
Cautions:
1. Ensure no gaps exist in insulation material joints..
2. Any tape must be applied with appropriate pressure. If applied too tightly insulation may shrink and lose its
insulating properties leading to condensation and loss of efficiency.
3. In indoor shield space, it is no necessary to bind belting, so as to avoid influencing insulation effect.
Correct repairing method for insulation cotton: (see the figure below)
straight-through joint

Copper pipe
Insulation
cotton
Insulation cotton
19-11/16(500mm)

Firstly cut out the material longer than gap, expend the two ends and embed the insulated cotton, at last, paste
joint with glue.
Main points of insulation repairing:
1. Repaired length of insulation (insulation tube with filled gap) shall be 1-31/32~3-15/16‖(50~100mm) longer
than the exposed area..
2. Sliver the cut of insulation to be repaired and cross-section shall be even.
3. Insert gap with insulation for repairing and cross-section shall be pressed tightly.
4. All cross-section and cut need to be pasted with glue.
5. Finally, bind the seam with rubber/plastic tape.
6. Prohibit conducting insulation by using binder fabric in concealed section, so as to avoid influencing
insulation effect.
7.2 Insulation of Condensation Pipe
1. Select rubber/plastic tube with a fire retardant of B1 rating.
2. Thickness of insulation layer is usually above 10mm.
3. The insulation material at water outlet should be fixed with glue to the unit body, so as to avoid condensation
and dripping.
4. No insulation will be implied if installed in a wall..
5. Use specified glue to seal the seam of insulation material, and then bind with cloth tape. The width of tape
shall not be less than 1-31/32‖(50mm). Ensure tape is fixed firmly to avoid condensation.
7.3 Duct insulation
1. Duct insulation
1) Insulation of duct parts and equipment should be conducted after confirming that the leakage test has been
completed and quality of duct is confirmed.
2) Common insulation materials include centrifugal glass cotton, rubber/plastic materials etc..
2. Insulation layer should be even and tight. Cracks, gaps and other defects are not allowed.
3. The supporting, hanging and mounting brackets of duct should be fixed on the outside of the insulation layer,
and insert bed timber between bracket and duct.
4. Thickness of insulation layer
1) When inlet and outlet duct are installed in rooms with no air-conditioning, the insulation thickness should be
Installation 113
R410A All DC Inverter V54+S Series 50/60Hz MCAC-VTSM-201605
above 1-37/64‖(40mm) when adopting centrifugal glass cotton for insulation.
2) When inlet and outlet duct are installed in a room with air conditioning, insulation thickness should be above
1‖(25mm) when adopting centrifugal glass cotton for insulation.
3) When adopting rubber/plastic or other materials, insulation thickness shall meet design requirements
according to relevant calculations.
8. Brazing cautions
 Ensure system is purged with sufficient nitrogen throughout all brazing operations. Correct use of nitrogen
during the brazing process prevents the formation of oxidation on the inside in copper piping. An oxidized
film adversely affects valves and compressors in the refrigerating system and prevents proper operation.
 The nitrogen pressure should be set to 2.9PSI(0.02MPa) with a pressure-reducing valve.

 Do not use anti-oxidants when brazing the pipe joints. Residue can clog pipes and damage equipment.
 Do not use flux when brazing copper-to-copper refrigerant piping. Use phosphor copper brazing alloy (BCuP)
which does not require flux.
 Flux has an extremely harmfully influence on refrigerant pipe systems. For instance, if chlorine based flux is
used, it will cause pipe corrosion, if the flux contains fluorine, it will deteriorate the lubrication properties of
refrigerant oil.
9. Remove dirt or water in the piping
 Make sure there is no dirt or water in the piping system before connecting the piping to the outdoor units.
 Flush the system with high pressure nitrogen, never use the outdoor units' refrigerant for this purpose.
10. Gas tightness test
10.1 Purpose and operation procedure of air tightness test
10.1.1 Purpose
Identify the source of leaks, make sure there is no leakage in system to prevent system fault due to leakage of
refrigerant.
10.1.2 Operation tips
Subsection detection, overall pressure-keeping, grading pressurization.
10.1.3 Operation procedure
1. After piping of indoor unit has been connected, weld port of high-pressure side piping.
2. Weld low-pressure side piping with connector for pressure gauge together.
3. Charge nitrogen slowly into pressure gauge connector to conduct air tightness test.
10.2 Operation of air tightness test
10.2.1 Operation procedure
1. When conducting air tightness test, make sure that gas and liquid piping are fully closed to prevent nitrogen
from entering the system. Both gas and liquid valve need to be strengthened before pressurization.
2. Each refrigerant system shall be slowly pressurized from both sides of gas and liquid pipe.
3. Use dry nitrogen to conduct air tightness test. Phase-in control diagram of pressurization is as follows:

10.2.2 Pressure observation
1. System pressure should be maintained for 24 hours. When pressure change is related to temperature
change according to below calculation, it means there are on leakage. If pressure falls, identify and address
the leakage source.
2. Modification method
When ambient temperature difference is ±1.8°F(1°C), the pressure difference shall be ±1.4PSI(0.1kgf/cm2).
Modification formula: Real value = pressure of pressurization + (temperature of pressurization – temperature
during observation)x1.4PSI(0.1kgf/cm2)
A pressure drop can be identified by comparing the modification value with pressurization value.
3. General method for identifying the source of a leak
Detection process involves three general steps.
1) Audio detection for identifying large leaks.
2) Touch detection -----place hand at the joint to feel the leakage
3) Soap water detection is used to identify small leaks. Escaping gas will create bubbles at the leak point after
soapy water is applied..
4) Detection by use of halogen leak detector
Use a halogen leak detector when finding the source of difficult to detect leakages..
a. Keep nitrogen at 42.6PSI(3.0kgf/cm2).
b. Supplement refrigerant to 71.1PSI(5.0kgf/cm2).
c. Use halogen leak detector, methane leak detector and electric leak detector for detection.
d. If the leak source cannot be found, continuously pressurize to 568.8PSI(40.0kgf/cm2) (R410A) and then
serach again.

4. Caution
1) The air tightness test is conducted by pressurized nitrogen (R410A system: 568.8PSI(40.0kgf/cm2)).
2) Oxygen, flammable gas and toxic gas shall not be used to conduct air tightness test.
3) Before pressure reading, let the system rest for several minutes till pressure is stable.
4) After test is complete, reduce system pressure to 71.1~113.7PSI(5~8kgf/cm2) and then conduct
pressure-keeping and storage.
5) If pipeline is too long, conduct phase-in detection.

11. Vacuum Drying
11.1 Purpose and main points of vacuum drying
11.1.1 Purpose of vacuum drying
1. Remove moisture from the system to prevent ice-blockage and copperizing. Ice-blockage will cause
abnormal operation, while copperizing may damage compressor.
2. Eliminating the non-condensable gas of system prevents oxidizing of internal components, system pressure
fluctuation, and low heat exchange performance..
3. Detect leak source from reverse rotate.
11.1.2 Selection of vacuum pump
1. Vacuuming suction must be less than -14.6PSI(756mmHg).
2. The discharge of vacuum pump is over 4L/s.
3. The precision of vacuum pump is over 0.001ft.H2O(0. 02mmHg).
R410A system caution:
After the vacuuming process of R410A refrigerant circulation system is complete, vacuum pump will stop
running. As a result of suction in the in the air conditioning system, vacuum pump lubricant will seep back into
the system. This, same situation will also occur if vacuum pump suddenly stops during operation. This will
cause different oils mix, leading to system malfunction, it is therefore recommended to use one-way valve to
prevent reverse flow of oil in vacuum pump.
11.1.3 Vacuum drying for piping
Vacuum drying: Use of vacuum pump effectively transfers moisture in lines from liquid to gas state. Typical
boiling point for water is 212F(100C)the vacuum pump reduces the internal pressure of the piping system thus
reducing the boiling point of water to room temperature. This process evaporates all moisture in the piping
system.

69.1(20. 6) 0.35(18) -14.35(-742)
11.2 Operation procedure
There are two vacuum drying methods: common and special.
11.2.1 Ordinary vacuum drying
1) Connect the pressure gauge to the infusing mouth of gas and liquid pipe, keep vacuum pump running for at
least 2 hours, ensures vacuum degree o is below -14.6PSI(-755mmHg).
2) If the vacuum degree is not below -14.6PSI(-755mmHg) after 2 hours of drying, system will continue drying
for one hour.
3) If the vacuum degree is not be below -14.6PSI(-755mmHg) after 3 hours of drying, check the system for
leaks.
4) Vacuum placement test: when the vacuum degree reaches -14.6PSI(-755mmHg), keep for 1 hour. If the
vacuum gauge indicator does not increase, the process is complete. If the vacuum gauge increases, it
indicates of moisture or a leak.
116 Installation
MCAC-VTSM-201605 R410A All DC Inverter V4+S Series 50/60Hz
5) Vacuum drying shall be conducted from liquid and gas pipe simultaneously. There are a lot of functional
parts like valves, which could shut down the gas flow midway.
11.2. 2 Special vacuum drying
Special vacuum drying method shall be adopted when:
1) Discovery of moisture during refrigerant piping flush.
2) Conducting construction on rainy day, because rain water might penetrated into pipeline.
3) Construction period is long, and rain water might penetrated into pipeline.
4) Rain water might penetrate into pipeline during construction.
Procedures of special vacuum drying are as follows:
a. First stage vacuum drying 2 hours.
b. The second vacuum damage, charging nitrogen to 7.1PSI(0.5kgf/cm2).
Because nitrogen is dry, vacuum damage could achieve the effect of vacuum drying, but this method cannot
sufficiently dry the system when there is too much moisture. Therefore, it is crucial to ensure that moisture
does not enter the system and condensation does not form.
c. Second stage vacuum drying 1 hour.
Vacuum drying is confirmed complete when vacuum degree is under -14.6PSI(-755mmHg); if the vacuum
degree is still above -14.6PSI(-755mmHg) within 2 hours drying, please repeat the procedures of ―vacuum
damage---vacuum drying‖.
d. Vacuum placement test: when the vacuum degree reaches -14.6PSI(-755mmHg), keep for 1 hour. If the
vacuum gauge indicator does not increase, the process is complete. If the vacuum gauge increases, it
indicates of moisture or a leak.
12. Additional refrigerant charge
12.1 Operation procedure for recharging refrigerant
12.1.1 Operation procedure
Calculate the required refrigerant volume by the length of liquid pipe → recharge refrigerant.
※The refrigerant volume from factory does not take into consideration actual installation piping length.
12.1.2 Steps for recharging refrigerant
1. Make sure vacuum drying is qualified before recharging refrigerant.
2. Calculate the required refrigerant volume by the diameter and the length of liquid pipe.
3. Use electronic scale or fluid infusion apparatus to weigh the recharged refrigerant volume.
4. Use soft pipe to connect refrigerant cylinder, pressure gauge, and examine valve of outdoor unit. And
recharge in liquid mode. Before recharging, clear the air in the soft pipe and pressure gauge’s pipe.
5. After recharge is finished, using gas leak detector or soap water, inspect for refrigerant leakage in expansion
part of indoor and outdoor units.
6. Write the recharged refrigerant volume in the indicating plate of outdoor unit.
Caution
1) The recharged refrigerant volume must be calculated according to the formula in the outdoor technical
reference manual. Calculation cannot be made according to running current, pressure and temperature as
current and pressure will change depending on the difference of temperature and length of pipeline.
2) In cold temperature, use warm water and hot air to warm up refrigerant storage cylinder.
12.1.3 Recharging R410A refrigerant
If R410A refrigerant is adopted, confirm the following items before recharging:
1) R410A refrigerant compatible vacuum pump with one-way valve.
2) R410A refrigerant compatible pressure gauge.
3) R410A refrigerant compatible recharging soft pipe and connector.
4) Charging method: Recharge in liquid phase.

5) The different leak detector.
12.2 Calculating the refrigerant recharge volume
Calculate the additional refrigerant charge according to the diameter and the length of the liquid side pipe of
the outdoor/indoor unit connection. The refrigerant is R410A.
Note: Assume equivalent pipe length of the branch joint is 0.5m (for calculation purposes).
Pipe size of liquid side ( in.(mm)) Additional refrigerant charge per meter (lbs.(kg))
Φ1/4(6.35) 0.049(0.022)
Φ3/8(9.53) 0.126(0.057)
Φ1/2(12.7) 0.243(0.110)
Φ5/8(15.9) 0.375(0.170)
Φ3/4(19.1) 0.573(0.260)
Φ7/8(22.2) 0.794(0.360)
Φ1(25.4) 1.147(0.520)
Φ1-1/8(28.6) 1.50(0.680)
 Charge the additional refrigerant from the gas pipe or liquid pipe. After the system is running, if it is needed
to charge refrigerant during maintenance, charge at the gauge point.
 Calculating formula (R410A):
 The recharged volume: R (kg) = (L1×0. 022 kg/m) + (L2×0. 057 kg/m) + (L3×0. 110 kg/m) + (L4×0.170 kg/m)
+ (L5×0. 260 kg/m) + (L6×0. 360 kg/m) + (L7×0. 520kg/m) + (L8×0. 680kg/m)
 L1: Actual total length of Φ6.35 liquid pipe (m); L2: Actual total length of Φ9.53 liquid pipe (m);
 L3: Actual total length of Φ12.7 liquid pipe (m); L4: Actual total length of Φ15.9 liquid pipe (m);

Note:
 Refrigerant piping system, signal wires between indoor units and outdoor units should be run together.
 Power supply for all indoor units must be unified.
 Do not put the signal wires and power wires in the same conduit; if power supply is less than 10A than a distance of over
300mm between conduits should be maintained, if power supply is between 10A to 50A than the separation distance should be
increased to 500mm.
13.4 Control system installation
The control line should be shielded wire. Using other wiring shall create signal interference, leading to malfunction.
The shielded nets at the two sides of shielded wires are either grounded, or connected with each other and jointed to the sheet
metal along to the earth.
Control wire could not be bound together with refrigerant pipeline and power wire. When power wire and control wire are run
parallel to each other they should be spaced a minimum of 11-13/16inch(300mm) so as to prevent signal interference.
Control wire shall not form a closed loop.
Control wire has polarity, so be careful when connecting.
The shield net should be grounded at the outdoor unit wiring terminal. The inlet and outlet wire net of indoor communication wire
should be connected directly and cannot be grounded, and form open circuit at the shield net of final indoor unit.
13.4.1 Signal wire between outdoor unit and indoor unit
Signal wire of indoor/outdoor unit adopts 3-core shielded wire (≥0.0012in.2(0.75mm2), The signal wire is
polarized and must be connected correctly.

13.4.3 Signal wire of centralized control
When centralized control is needed, one CCM03 (indoor unit central controller) can only control the indoor
units of the same refrigerant system via the X Y E port of the outdoor unit. Outdoor unit will automatically
distribute addresses to the indoor units. Remote controller can query and modify indoor unit addresses.
The diagram below is an example wiring:

CCM03 can also connect indoor units via the X Y E port of indoor unit. This method requires another set of X
Y E cable between indoor units and is therefore more complex and not the first recommendation. The diagram
below is an example wiring:

Note:
If the wiring connection of each outdoor unit is in A, B, C phase sequence, and multiple units are connected, the current
difference between C phase and A, B phase will be very large as the power supply load of each outdoor unit is on C phase, this
can easily lead to tripped breakers and terminal wiring burnout. Therefore if multiple units are to be used, the phase sequence
should be staggered, so that the current can be distributed among the three phases equally.

Measure the resistance between each two of U, V, W terminals of the compressor, all resistance levels should
be the same and equal to 0.9~5 Ohms. (Fig. A and Fig. B)
Measure the resistance between each of U, V, W terminals of the compressor and ground (Fig. C), all the
resistance should be infinite (Fig. D), otherwise the compressor has malfunctioned and needs to be replaced.

1) DC voltage between terminal P and terminal N should be 1.41 times the local power supply voltage.
2) DC voltage between terminal 1 and 2 should be 510V～580V.
3) Disconnect the terminal 3, 4, and 5 from inverter compressor. Measure the resistance between any two
terminals among terminal 1, 2, 3, 4, 5. All the values should be infinite. If any of the value approximates to 0,
the inverter module is damaged and should be replaced.
After replacing the inverter module, if the system is still abnormal, then go to step 3.
Step 3: DC generatrix check
Direction of the current in DC supply wire which is running through the inductor should be the same as the
direction of arrow marked on the inductor.

If the resistance values are normal, then go to step 2.
Step 2: Disconncet the power wiring from the compressor(named compressor A) of the faulted system(named
system A).
If there is a system running normally nearby (named system B):
Extend the power line of the inverter compressor of system B, connect compressor A to the control box of
system B, make sure that the U, V, W terminals are connected in right order, then start system B.
If compressor A can start normally, that means compressor is OK, the control box of system A has
malfunctioned, then replace the main PCB of system A and ensure correct wiring.
If compressor A can not start normally, that means compressor A is damaged and needs to be replaced.

Step 1: Remove the compressor from the faulty outdoor unit, pour out the oil from the compressor according to
the method illustrated. Normally the oil will flow out from the discharge pipe of the compressor.

Step 2: Inspect system oil

Normally the oil should be clear and transparent, slightly yellow is also not an indication on any problems.
However, if the oil is dark, black or contains impurities, the system has problems and the oil needs to be
changed.

Note:
1. Before removing the oil, shake the compressor, oil separator and gas-liquid separator first, so as to not allow
impurities to settle at the bottom of the tank.
2. If the oil of one compressor is clean, there’s no need to check the oil of the other compressor. If the oil of one
compressor has gone bad, it is necessary to check the oil of the other compressor. If all the oil of an outdoor
unit needs to be replaced, after adding oil to the compressors, the rest oil should be charged to the gas-liquid
separator.
3. Add oil to the compressor from the discharge pipe.
