PERFORMANCE CURVES

The standard data contained in these specifications apply only to the operation of the air conditioner under normal condition. 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 : ˚C WB (2) Indoor outlet air wet-bulb temperature : ˚C WB (3) Outdoor intake air dry-bulb temperature : ˚C DB (4) Total input : W

The table of Indoor air wet-bulb temperature difference at the bottom left on page 15 shows the difference between the indoor intake air wet-bulb temperature and the indoor outlet air wet-bulb temperature for your reference at service.

How to measure the indoor air wet-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 dry-bulb thermometers to the outdoor air intake.

Cover the thermometers to avoid 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 to start the EMERGENCY operation.

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.
