2 TECHNICAL CHANGES

INFORMATION FOR THE AIR CONDITIONER WITH R410A REFRIGERANT

• This room air conditioner adopts an HFC refrigerant (R410A) which never destroys the ozone layer.
• Pay particular attention to the following points, though the basic installation procedure is same as that for R22 conditioners.
1 As R410A has working pressure approximate 1.6 times as high as that of R22, some special tools and piping parts/
materials are required. Refer to the table below.
2 Take sufficient care not to allow water and other contaminations to enter the R410A refrigerant during storage and
installation, since it is more susceptible to contaminations than R22.
3 For refrigerant piping, use clean, pressure-proof parts/materials specifically designed for R410A. (Refer to 2. Refrigerant
piping.)
4 Composition change may occur in R410A since it is a mixed refrigerant. When charging, charge liquid refrigerant to prevent
composition change.

1. Tools dedicated for the air conditioner with R410A refrigerant

The following tools are required for R410A refrigerant. Some R22 tools can be substituted for R410A tools.
The diameter of the service port on the stop valve in outdoor unit has been changed to prevent any other refrigerant being
charged into the unit. Cap size has been changed from 7/16 UNF with 20 threads to 1/2 UNF with 20 threads.

R410A tools Can R22 tools be used? Description

R410A has high pressures beyond the measurement range of existing
Gauge manifold No gauges. Port diameters have been changed to prevent any other refrigerant
from being charged into the unit.

2. Refrigerant piping
1 Specifications
Use the refrigerant pipes that meet the following specifications.

Outside diameter Wall

Pipe Insulation material
mm thickness
For liquid 6.35 0.8 mm
Heat resisting foam plastic
9.52 0.8 mm
For gas Specific gravity 0.045 Thickness 8 mm
12.7 0.8 mm

• Use a copper pipe or a copper-alloy seamless pipe with a thickness of 0.8 mm. Never use any pipe with a thickness less
than 0.8mm, as the pressure resistance is insufficient.

2 Flaring work and flare nut

Flaring work for R410A pipe differs from that for R22 pipe.
For details of flaring work, refer to Installation manual “FLARING WORK”.

Pipe diameter Dimension of flare nut

mm R410A R22
6.35 17 17
9.52 22 22
12.7 26 24

3. Refrigerant oil
Apply the special refrigeration oil (accessories: packed with indoor unit) to the flare and the union seat surfaces.

4. Air purge
• Do not discharge the refrigerant into the atmosphere.
Take care not to discharge refrigerant into the atmosphere during installation, reinstallation, or repairs to the refrigerant
circuit.
• Use the vacuum pump for air purging for the purpose of environmental protection.

5. Additional charge
For additional charging, charge the refrigerant from liquid phase of the gas cylinder.
If the refrigerant is charged from the gas phase, composition change may occur in the refrigerant inside the cylinder and the
outdoor unit. In this case, ability of the refrigerating cycle decreases or normal operation can be impossible. However,
charging the liquid refrigerant all at once may cause the compressor to be locked. Thus, charge the refrigerant slowly.

How to measure the indoor air wet-bulb/dry-bulb temperature difference
1. Attach at least 2 sets of wet-and-dry-bulb thermometers to the indoor air inlet as shown in the figure, and at least 2 sets of
wet-and-dry-bulb thermometers to the indoor air outlet. The thermometers must be attached to the position where air speed
is high.
2. Attach at least 2 sets of wet-and-dry-bulb thermometers to the outdoor air inlet.
Cover the thermometers to prevent direct rays of the sun.
3. Check that the air filter is cleaned.
4. Open windows and doors of the room.
5. Press the EMERGENCY OPERATION switch once to start the COOL(HEAT) MODE.
6. When system stabilizes after more than 15 minutes, measure temperature and take an average temperature.
7. 10 minutes later, measure temperature again and check that the temperature does not change.

OUTDOOR LOW PRESSURE AND OUTDOOR UNIT CURRENT

<How to operate fixed-frequency operation (Test run operation)>
1. Press the TEST button to COOL or HEAT mode.
2. Test run operation starts and continue to operate for 30 minutes.
3. Compressor starts at rated frequency in COOL mode or 58Hz in HEAT mode.
4. Indoor fan operates at High speed.
5. After 30 minutes, test run operation finishes and EMERGENCY OPERATION starts.
6. To cancel test run operation (EMERGENCY OPERATION), press the ON/OFF button on remote controller.
NOTE : The unit of pressure has been changed to MPa on the international system of units (SI unit system).
f [Gauge])
The conversion factor is: 1(MPa [Gauge]) =10.2(kgf/f

SUZ-A09VR.TH SUZ-A12VR.TH SUZ-A18VR.TH SUZ-A24VR.TH

12-1. Cautions on troubleshooting
12-1-1. Before troubleshooting, check the following:
1) Check the power supply voltage.
2) Check the indoor/outdoor connecting wire for mis-wiring.
12-1-2. Take care the following during servicing.
1) Before servicing the air conditioner, be sure to first turn off the remote controller to stop the main unit, and then after
confirming the horizontal vane is closed, turn off the breaker and / or disconnect the power plug.
2) Be sure to turn OFF the power supply before removing the front panel, the cabinet, the top panel, and the inverter
control P.C. board or electronic control P.C. board.
3) When removing the electrical parts, be careful to the residual voltage of smoothing capacitor.
4) When removing the inverter P.C. board, hold the edge of the board with care NOT to apply stress on the components.
5) When connecting or disconnecting the connectors, hold the housing of the connector. DO NOT pull the lead wires.

Lead wiring Housing point

12-1-3. Troubleshooting procedure
For SLZ/SUZ
1) First, check if the OPERATION INDICATOR lamp on the indoor unit is flashing on and off to indicate an abnormality.
To make sure, check how many times the abnormality indication is flashing on and off before starting service work.
2) Before servicing check that the connector and terminal are connected properly.
3) If the inverter P.C. board or electronic control P.C. board is supposed to be defective, check the copper foil pattern for
disconnection and the components for bursting and discolouration.
4) When troubleshooting, refer to the flow chart on page 43 for SLZ-A09AR.TH, SLZ-A12AR.TH, SUZ-A09VR.TH and
SUZ-A12VR.TH and page 45 for SLZ-A18AR.TH and SUZ-A18VR.TH.

For SEZ/SUZ
1) First, check if the OPERATION lamp on the remote controller is flashing and off to indicate an abnormality.
To make sure, check the ERROR CODE on the remote controller.
2) Before servicing check that the connector and terminal are connected properly.
3) If the inverter P.C. board or electronic control P.C. board is supposed to be defective, check the copper foil pattern for
disconnection and the components for bursting and discolouration.
4) When troubleshooting, refer to the flow chart on page 44 for SEZ-A09CR.W, SEZ-A12AR.TH, SUZ-A09AR.TH and
SUZ-A12AR.TH and page 46 for SEZ-A18AR.W, SEZ-A24AR.TH, SUZ-A18AR.TH and SUZ-A24AR.TH.
