<Preparation before the repair service>

Prepare the proper tools.
Prepare the proper protectors.
Provide adequate ventilation.
After stopping the operation of the air conditioner, turn off the power-supply breaker and remove the power plug.
Discharge the capacitor before the work involving the electric parts.

<Precautions during the repair service>

Do not perform the work involving the electric parts with wet hands.
Do not pour water into the electric parts.
Do not touch the refrigerant.
Do not touch the hot or cold areas in the refrigeration cycle.
When the repair or the inspection of the circuit needs to be done without turning off the power, exercise great caution not to

touch the live parts.

Use the specifi ed refrigerant only

Never use any refrigerant other than that specified.

Doing so may cause a burst, an explosion, or fire when the unit is being used, serviced, or disposed of.
Correct refrigerant is specified in the manuals and on the spec labels provided with our products.
We will not be held responsible for mechanical failure, system malfunction, unit breakdown or accidents caused by
failure to follow the instructions.

Refrigerant pipe diameter is different according to indoor unit to be connected. When using extension pipes, refer to the

tables below.

When diameter of refrigerant pipe is different from that of outdoor unit union, use optional Different-diameter pipe.

When relocating or disposing of the air conditioner, pump down the system following the procedure below so that no refriger­ant is released into the atmosphere.

1) Turn off the breaker.

2) Connect the gauge manifold valve to the service port of the stop valve on the gas pipe side of the outdoor unit.

3) Fully close the stop valve on the liquid pipe side of the outdoor unit.

4) Turn on the breaker.

5) Start the emergency COOL operation on all the indoor units.

6) When the pressure gauge shows 0.05 to 0 MPa [Gauge] (approximately 0.5 to 0 kgf/cm²), fully close the stop valve
on the gas pipe side of the outdoor unit and stop the operation. (Refer to the indoor unit installation manual about the
method for stopping the operation.)

* If too much refrigerant has been added to the air conditioner system, the pressure may not drop to

0.05 to 0 MPa [Gauge]

(approximately 0.5 to 0 kgf/cm²)

, or the protection function may operate due to the pressure increase in the high-pres­sure refrigerant circuit. If this occurs, use a refrigerant collecting device to collect all of the refrigerant in the system, and
then recharge the system with the correct amount of refrigerant after the indoor and outdoor units have been relocated.

7) Turn off the breaker. Remove the pressure gauge and the refrigerant piping.

When pumping down the refrigerant, stop the compressor before disconnecting the refrigerant pipes.
The compressor may burst and cause injury if any foreign substance, such as air, enters the pipes.

PERFORMANCE CURVES

The standard 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 pro-

vided to clarify the operating characteristics of the air conditioner under the conditions indicated by the performance curve.

(1) GUARANTEED VOLTAGE

198 - 264 V 50 Hz

(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
(5) Indoor intake air dry-bulb temperature: °CDB
(6) Outdoor intake air wet-bulb temperature: °CWB
(7) Total input: W

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

How to measure the indoor air wet and 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 (twice) to start the EMERGENCY 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.
