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
Rated voltage : ±10% SU-NR(198~242V 60Hz) / SU(H)-VR(198~264V 50Hz)
(2) AIR FLOW
Air flow should be set at MAX.
(3) MAIN READINGS
COOLING
(1) Indoor intake air wet-bulb temperature : W.B.

Indoor air wet/dry-bulb temperature difference on the side of the chart on 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 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 TEST RUN 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.
