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
(2) AIR FLOW
Air flow should be set at MAX.
(3) MAIN READINGS
COOLING
(1) Indoor intake air wet-bulb temperature : W.B. ˚C
(2) Indoor outlet air wet-bulb temperature : W.B. ˚C
(3) Outdoor intake air dry-bulb temperature : D.B. ˚C
(4) Total input : W
Indoor air wet/dry-bulb temperature difference on the side of the following chart 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.
HEATING
(1) Indoor intake air dry-bulb temperature : D.B. ˚C
(2) Indoor outlet air dry-bulb temperature : D.B. ˚C
(3) Outdoor intake air wet-bulb temperature : W.B. ˚C
(4) Total input : W
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.
