MUZ-FH25VE MUZ-FH35VE

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.

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.

PERFORMANCE CURVES8

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 provided 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: °C [WB]

}

Cooling

(2) Indoor outlet air wet-bulb temperature: °C [WB] (3) Outdoor intake air dry-bulb temperature: °C [DB] (4) Total input: W (5) Indoor intake air dry-bulb temperature: °C [DB]

}

Heating(6) Outdoor intake air wet-bulb temperature: °C [WB] (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.

1. Press EMERGENCY OPERATION switch to start COOL or HEAT mode (COOL: Press once, HEAT: Press twice).

2. Test run operation starts and continues to operate for 30 minutes.

3. Compressor operates at rated frequency in COOL mode or 58 Hz in HEAT mode.

4. Indoor fan operates at High speed.

After 30 minutes, test run operation finishes and EMERGENCY OPERATION starts (operation frequency of compressor varies).

6. To cancel test run operation (EMERGENCY OPERATION), press EMERGENCY OPERATION switch or any button on remote controller.
