Starting your air conditioner
Operating your air conditioner properly helps you to obtain the best possible results.
This section explains proper air conditioner operation.
IMPORTANT:
• If you turn the air conditioner off, wait at least 3
minutes before turning it back on. This prevents the air
conditioner from blowing a fuse or tripping a circuit
breaker.
• Do not try to operate your air conditioner in the cooling
mode when outside temperature is below 65°F (18°C).
The inside evaporator coil will freeze up and the air
conditioner will not operate properly.
Operating Your Air Conditioner
4
FAN CONTROL
Set the FAN CONTROL to the desired setting. When the air conditioner is operating at LOW
COOL, MED COOL (some models) or TURBO COOL, the fan circulates air continuously.
LOW COOL – for sleeping comfort
MED COOL (some models) – for normal cooling
TURBO COOL – for maximum cooling
FAN ONLY
When the FAN ONLY setting is selected, the fan will run continuously to move air, but the
air will not be cooled.
THERMOSTAT
Turn the THERMOSTAT Control to a mid-setting. Adjust the air conditioner's performance
by turning the THERMOSTAT Control clockwise ( ) for maximum cooling. For less
cooling, turn the THERMOSTAT Control counterclockwise ( ). Experiment and find the
setting that suits you best.
The louvers in the top of the front panel
allow you to control the direction of the
cooled air. Use the tabs to direct the air
up, down, right, left, or straight ahead.

There are many things you can do to help save energy.
Saving energy
• Improve your home's insulation. Seal doors and
windows. Close fireplace flue.
• Close blinds or drapes on the sunny side of your
house. Add awnings.
• Make sure drapes or furniture do not block airflow
from your air conditioner.
• Turn lights and appliances off when they are not
needed.
• Ventilate your attic. High temperatures in the attic
add to the air conditioner's cooling load.
• Try not to use heat-producing appliances during the
hottest part of the day.
• Keep heat registers and cool-air returns closed.
• Use exhaust vent fans while cooking, doing laundry,
or bathing.
When your air conditioner is operating normally, you may hear sounds such as:
Normal operating sounds
• Droplets of water hitting the condenser, causing a
“pinging” or “clicking” sound. The water droplets
help cool the condenser.
• Air movement from the fan.
• Clicks from the thermostat cycle.
• Vibrations or noise due to poor wall or window
construction.
• A high-pitched hum or pulsating noise caused by
the modern high-efficiency compressor cycling on
and off.
