Fan Speed switch to High, and slide
Fan Auto/On switch to On position.

2. Indoor fan turns on in high

speed.

3. Slide Fan Speed switch to Low.

4. Indoor fan slows to low speed.

5. Slide Fan Auto/On switch to Auto position.

6. Indoor fan turns off.

Cool Test

is displayed.

2. Adjust set temperature so it is 5 degrees below room
temperature.

3. Air conditioning should come on within a few seconds.

4. Adjust the set temperature so it is 2 degrees above the

room temperature and the A/C should turn off. Note:
There is a 3 minute time delay and a 3 minute minimum
run time for the compressor when it turns on/off. (On
some models, the fan may also have a minimum run time/
off time delay).
