Indoor air wet/dry-bulb temperature difference on the left side of the chart on this page and next 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 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.
