AIR CONDITIONER FEATURES AND OPERATION INSTRUCTIONS

WARNING: To reduce the risk of fire, electric shock, or injury to persons, read the important safety instructions before
operating this appliance.

NOTE: If the air conditioner is turned off, wait 3 minutes before restarting. This allows pressure inside the compressor
to equalize. Failure to follow these instructions may result in damage to your unit.

To begin operating the air conditioner, follow these steps:

1. Set the thermostat to the highest number (coldest setting).

2. Set the selector control to the HI COOL setting.

3. Adjust the louver for comfortable airflow.

4. Once the room has cooled, adjust the thermostat to the setting you find most comfortable.

5. Make sure that the air flow inside and outside are not obstructed by anything.

NOTE: This air conditioner is designed to be operated under the following conditions:

64°F - 110°F (18°C- 43°C)
62°F - 89°F (17°C - 32°C)

Performance may be reduced if unit is operated above or below these operating temperature ranges.
