PRECAUTIONS

•
Allow 3 minutes for the compressor to restart cooling.
If you turn the air conditioner off and immediately restart it, allow three minutes for the compressor to
restart cooling. There is an electronic device in the unit that keeps the compressor off three minutes for
protection.
•
If a power failure occurs during use, allow 3 minutes before restarting the unit.
After power is reinstated, restart the air conditioner. If the power was off for less than three minutes, be
sure to wait at least three minutes before restarting the unit. If you restart the air conditioner within three
minutes, a protective device in the unit may cause the compressor to shut off. This protective device will
prevent cooling for about 5 minutes.
Memory settings will be cancelled and the unit will return to factory presettings.
• Dehumidifying function
The air conditioner removes moisture from the air in your room.
•
Cooling operation under low temperatures: Is your unit freezing up?
The unit operates on inside and outside temperatures. Freezing can occur when the temperature is set
close to 64°F and when there are low outside temperatures, especially during the night hours. At these
conditions, a further temperature drop may cause the unit to freeze. Setting the unit to a higher
temperature will prevent it from freezing.

NOTES ON OPERATION

ENERGY EFFICIENCY TIPS

•Setting the proper temperature.
For optimum energy efficiency, keep the difference between the inside and outside temperature within
10°F(5°C). Do not keep the temperature setting any lower than is necessary for you to feel comfortable.
Generally, 78°F to 80°F(26°C to 27°C) is a comfortable summer indoor temperature.
When you turn the unit on, do not set the temperature higher than the room temperature at start up as
this will not allow the compressor to cycle and maintain a comfortable room temperature.
•Avoid direct sunlight.
Close blinds, drapes or shades to keep out direct sunlight during cooling operation.
•Keep the filter clean.
Keeping the filter clean greatly aids efficient operation. A dirty filter blocks the flow of air, making your air
conditioner work harder and less efficiently. See page 18 on how to clean the filter.
•Turn off unnecessary light.
Your air conditioner must remove the heat produced by your lights or other heat-producing appliances.
Turn off lights or appliances that are not in use.
•Install your air conditioner in a shady location.
Direct sunlight on a window air conditioner increases its workload and will increase its operating cost.
•Don't let cool air escape.
Close windows and outside doors. Do not keep doors open and let hot air rush in. Improperly installed
air conditioners and improperly weatherstripped doors and windows will let hot air in and the cool air out.
•Turn off air conditioner when no one is home.
Use only when necessary. The fewer hours a room air conditioner is used, the lower the operating cost.
