MPS(Multi Power System) Variable Control :
Big Energy Saving with MPS Control

• Basic Principle of MPS Control

MPS control provides comfortable and convenient environment as there are two compressors with 60&40%
load sharing with on compressor of small capacity always working to maintain the set temperature conditions
& meanwhile other compressor is at rest if the load is low whereas in conventional system the only
compressor is working with ON/OFF cycles.
Conventional (On/Off Operation) MPS Control

100% 40% 60%

• Comfort Control
- Conventional Operation : The compressor must turn on and off to reach desired temperature setting. A
large portion of power is used during restarting. This causes unnecessary power consumption.
- MPS(Multi Power System) Control : This is a power saving system with two rotary compressors of different
capacity (60% & 40%) operating an A/C at high power until it reaches desired temperature. And when it
reaches the temperature, only the 40% capacity rotary compressor operates.

Innovative Quiet Operation

To provide a comfortable, pleasant and well
balanced environment, LG air conditioners utilize a
streamlined air fan and a unique design which create
smooth air flow from the air conditioner so that it
operates under the lowest noise level. The cross flow
fan, stabilizer, and rear guide which are the causes
of noise, have been redesigned by hydraulic
engineering. The number of revolutions have been
decreased or increased while the amount of friction
has been decreased providing the most quiet air
conditioners in the world.

CHAOS Swing
The most pleasant air flow for the human body can
be found within nature. Countless data and
verification resulted in the application of the new
Up Speed :Slow
CHAOS theory to LG Air conditioners.

In some of the places natural drainage is not
possible. For such places drain pump is very useful. It
removes condensed water from the unit.

Zone Control(Accessory)
It controls the temperature of each zone. Opening or
closing of the damper is controlled by sensing the
temperature of each zone. In the cooling mode, if the
temperature of a particular zone is lower than set
temperature then the damper is closed. On the other
hand if the temperature of a particular zone is higher
than the set temperature, damper is opened to
provide cooling to the zone and vice versa in the
heating mode.

2) Attach the Grille onto the cabinet.

• Grasp lower the left and right side of the Grille
and engage four tabs on the top inside edge of
the chassis.
• Press the Grille toward the chassis until it will be
back into place.

CAUTION
After the confirmation of the above conditions, prepare the wiring as follows:
1) Never fail to have an individual power circuit specifically for the air conditioner. As for the
method of wiring, be guided by the circuit diagram posted on the inside of control cover.
2) The screw which fasten the wiring in the casing of electrical fittings are liable to come loose from
vibrations to which the unit is subjected during the course of transportation. Check them and
make sure that they are all tightly fastened. (If they are loose, it could cause burn-out of the
wires.)
3) Specification of power source.
4) Confirm that electrical capacity is sufficient.
5) See to that the starting voltage is maintained at more than 90 percent of the rated voltage marked
on the name plate.
6) Confirm that the cable thickness is as specified in the power source specification.
(Particularly note the relation between cable length and thickness.)
7) In a wet or moist area, always install an earth leakage circuit breaker.
8) The following would be caused by voltage drop.
• Vibration of a magnetic switch, which will damage the contact point, fuse breaking, disturbance of the
normal function of the overload.
9) The means for disconnection from a power supply shall be incorporated in the fixed wiring and
have an air gap contact separation of at least 3mm in each active(phase) conductors.

8.2 Connecting the cable

1) Connect the wires to the terminals on the
control board individually according to the
outdoor unit connection.
• Ensure that the color of the wires of outdoor
unit and the terminal No. are the same as those
of indoor unit respectively.
Connecting cable

Connected to Outdoor unit (Or BD Unit)

2) Attach the Grille onto the cabinet.

• Grasp lower the left and right side of the Grille
and engage four tabs on the top inside edge of
the chassis.
• Press the Grille toward the chassis until it will be
back into place.

CAUTION
After the confirmation of the above conditions, prepare the wiring as follows:
1) Never fail to have an individual power circuit specifically for the air conditioner. As for the
method of wiring, be guided by the circuit diagram posted on the inside of control cover.
2) The screw which fasten the wiring in the casing of electrical fittings are liable to come loose from
vibrations to which the unit is subjected during the course of transportation. Check them and
make sure that they are all tightly fastened. (If they are loose, it could cause burn-out of the
wires.)
3) Specification of power source.
4) Confirm that electrical capacity is sufficient.
5) See to that the starting voltage is maintained at more than 90 percent of the rated voltage marked
on the name plate.
6) Confirm that the cable thickness is as specified in the power source specification.
(Particularly note the relation between cable length and thickness.)
7) Always install an earth leakage circuit breaker in a wet or moist area.
8) The following would be caused by voltage drop.
• Vibration of a magnetic switch, which will damage the contact point, fuse breaking, disturbance of the
normal function of the overload.
9) The means for disconnection from a power supply shall be incorporated in the fixed wiring and
have an air gap contact separation of at least 3mm in each active(phase) conductors.

• A place where the unit will be leveled and that can

support the weight of the unit.
• A place where the unit can withstand its vibration.
• A place where service can be easily performed.

NOTE:
• Throughly study the following installation locations:
1. In such places as restaurants and kitchens, considerable amount of oil steam and flour adhere to the fan, the fin of the heat
exchanger, resulting in heat exchange reduction, spraying, dispersing of water drops, etc.
In these cases, take the following actions:
• Make sure that the ventilation fan for smoke-collecting hood on a cooking table has sufficient capacity so that it draws oily
steam which should not flow into the suction of the air conditioner.
• Make enough distance from a cooking room to install the air conditioner in such a place where it may not suck in oil steam.
2. Avoid installing air conditioner in such circumstances where cutting oil mist or iron powder is in suspension in factories, etc.
3. Avoid places where inflammable gas is generated, flows in, is stored or vented.
4. Avoid places where sulfurous acid gas or corrosive gas is generated.
5. Avoid places near high frequency generators.

• A place where the unit will be leveled and that can

support the weight of the unit.
• A place where the unit can withstand its vibration.
• A place where service can be easily performed.

NOTE:
• Throughly study the following installation locations:
1. In such places as restaurants and kitchens, considerable amount of oil steam and flour adhere to the fan, the fin of the heat
exchanger, resulting in heat exchange reduction, spraying, dispersing of water drops, etc.
In these cases, take the following actions:
• Make sure that the ventilation fan for smoke-collecting hood on a cooking table has sufficient capacity so that it draws oily
steam which should not flow into the suction of the air conditioner.
• Make enough distance from a cooking room to install the air conditioner in such a place where it may not suck in oil steam.
2. Avoid installing air conditioner in such circumstances where cutting oil mist or iron powder is in suspension in factories, etc.
3. Avoid places where inflammable gas is generated, flows in, is stored or vented.
4. Avoid places where sulfurous acid gas or corrosive gas is generated.
5. Avoid places near high frequency generators.

Make sure that the screws of the terminal are free from looseness.

Clamping of cables
1) Arrange 2 power cables on the control panel.
2) First, fasten the steel clamp with a screw to the inner boss of control panel.
3) For the cooling model, fix the other side of the clamp with a screw strongly. For the heat pump model, put the
0.75mm2 cable(thinner cable) on the clamp and tighten it with a plastic clamp to the other boss of the control
panel.
4) In Australia, the length of power supply cord measured from the entry of the power supply cord to the middle of
live pin on the power plug should be over 1.8m.

1) Never fail to have an individual power specialized for the air conditioner. As for the method of wiring, be guided by the
circuit diagram pasted on the inside of control box cover.
2) Provide a circuit breaker switch between power source and the unit.
3) The screw which fasten the wiring in the casing of electrical fittings are liable to come loose from vibrations to which the
unit is subjected during the course of transportation. Check them and make sure that they are all tightly fastened. (If they
are loose, it could give rise to burn-out of the wires.)
4) Specification of power source
5) Confirm that electrical capacity is sufficient.
6) Be sure that the starting voltage is maintained at more than 90 percent of the rated voltage marked on the name plate.
7) Confirm that the cable thickness is as specified in the power sources specification.
(Particularly note the relation between cable length and thickness.)
8) Never fail to equip a leakage breaker where it is wet or moist.
9) The following troubles would be caused by voltage drop-down.
• Vibration of a magnetic switch, damage on the contact point there of, fuse breaking, disturbance to the normal function of a
overload protection device.
• Proper starting power is not given to the compressor.

11.1 Selection of the best location
• If an awning is built over the unit to prevent direct sunlight or rain exposure, make sure that heat radiation from
the condenser is not restricted.
• Do not place animals and plants in the path of the warm air.
• Take the air conditioner weight into account and select a place where noise and vibration are minimum.
• Select a place so that the warm air and noise from the air conditioner do not disturb neighbors.
• Rooftop Installations : If the outdoor unit is installed on a roof structure, be sure to level the unit. Ensure the
roof structure and anchoring method are adequate for the unit location. Consult local codes regarding rooftop
mounting.

Necessity of a trap

Since there is fear of the oil held inside the riser piping
flowing back into the compressor when stopped and
causing liquid compression phenomenon, or cases of
deterioration of oil return, it will be necessary to
provide a trap at an appropriate place in the riser gas
piping.

In case more then 5m

CAUTION
• Capacity is based on standard length and maximum
allowance length is on the basis of reliability.
• Oil trap should be installed every 5~7 meters.
