INFORMATION FOR THE AIR CONDITIONER WITH R410A REFRIGERANT

• This room air conditioner adopts 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 R410Arefrigerant 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.

NOTE : The unit of pressure has been changed to MPa on the international system of units(SI unit system).

New Specification Current Specification

The incompatible refrigeration oil easily separates from refrigerant and is in the upper layer inside the suction muffler. Raising position of the oil back hole enables to back the refrigeration oil of the upper layer to flow back to the compressor.

Since refrigerant and refrigerating oil are compatible each, refrigeration oil goes back to the compressor through the lower position oil back hole.

Description

Clamp bar hole has been enlarged to reinforce the spring strength in the tool. Provided for flaring work (to be used with R22 flare tool).

Provided to prevent the back flow of oil. This adapter enables you to use vacuum pumps.

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.

1 Specifications

Use the refrigerant pipes that meet the following specifications.

• Use a copper pipe or a copper-alloy seamless pipe with a thickness of 0.8 mm (6.35, 9.52, 12.7), 1.0 mm (15.88). Never use any pipe with a thickness less than 0.8 mm (6.35, 9.52, 12.7), 1.0 mm (15.88), 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”.

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 refrigeration 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.

PERFORMANCE CURVES

MUCF- GA35VB MUCF-GA50VB MUCF-GA60VB

The standard data contained in these specifications apply only to the operation of the air conditioner under normal conditions,

since operating conditions vary according to the areas where these units are installed. The following information has been provided to clarify the operating characteristics of the air conditioner under the conditions indicated by the performance curve.

(1) GUARANTEED VOLTAGE

198 ~ 264V, 50Hz

(2) AIR FLOW

Air flow should be set at MAX.

(3) MAIN READINGS

(1) Indoor intake air wet-bulb temperature : °CWB (2) Indoor outlet air wet-bulb temperature : °CWB (3) Outdoor intake air dry-bulb temperature : °CDB (4) Total input: W

Indoor air wet/dry-bulb temperature difference on the left side of the chart on this page shows the difference between the indoor intake air wet/dry-bulb temperature and the indoor outlet air wet/dry-bulb temperature for your reference at service.

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 intake 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 intake. Cover the thermometers to prevent direct rays of the sun.

3. Check that the air filter is cleaned.

4. Open windows and doors of room.

5. Press the EMERGENCY OPERATION switch once to start the EMERGENCY COOL 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.

Indoor unit doesn't operate when the EMERGENCY OPERATION switch is pressed.

Check room temperature thermistor. Refer to "Test point diagram and voltage".

Check of wiring diagram of outdoor unit on page 8.w2

Refer to "Check of remote controller and receiver P.C. board".

Refer to "Check of indoor electronic control P.C. board".

2-time flash Cause: Indoor unit

• Trouble of room temperature/ indoor coil thermistor

Check room tempreture thermistor and indoor coil thermistor. Refer to "Test point diagram and voltage".

When the remote controller is pressed or when the EMERGENCY OPERATION switch is pressed, the fan doesn't rotate, with OPERATION INDICATOR lamp on.

Refer to "Check of indoor fan motor".

Refer to indoor unit service manual.

w2 Before checking the outdoor unit, make sure if any signal or power is being transmitted from the indoor unit.

4-time flash Cause: Indoor unit

• Trouble of indoor unit control system

Replace the indoor electronic control P.C. board.

w1 "Test Run operation" means the operation within 30 minutes after EMERGENCY OPERATION switch is pressed.

9-1. Cautions on troubleshooting

1. Before troubleshooting, check the following:

(1) Check the power supply voltage. (2) Check the indoor/outdoor connecting wire for mis-wiring.

2. Take care the following during servicing.

(1) Before servicing the air conditioner, be sure to turn OFF the main unit first with the remote controller, and then after con-

firming 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 electronic

control P.C. board.

(3) When removing the electronic control P.C. board, hold the edge of the board with care NOT to apply stress on the com-

ponents.

(4) When connecting or disconnecting the connectors, hold the housing of the connector. DO NOT pull the lead wires.

3. Troubleshooting procedure

(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 that the connector and terminal are connected properly. (3) If the electronic control P.C. board is supposed to be defective, check the copper foil pattern for disconnection and the

components for bursting and discoloration. (4) When troubleshooting, refer to the flow chart on this page.
