Operating Your Air Conditioner
Operating your air conditioner properly helps you to obtain the best possible result.
This section explains proper air conditioner operation.
IMPORT ANT:
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
0
F(180C). The inside evaporator coil will freeze up and the air conditioner will not
operate properly.
Starting your air conditioner
1.Set the EXHAUST Control(some models) to CLOSED for maxi-
mum continuous cooling. The EXHAUST Control set to OPEN
positions allows you to draw stale air and/or smoke from the
room.
OPEN-to exhaust room air to the outside.
CLOSED-to circulate room air.
The EXHAUST Control will function only when the FAN CONTROL
is operating.
2.Set the UNIT CONTROL to the desired setting.
When the air conditioner is operating at LOW
Your air conditioner has one of these controls:
COOL, MED COOL(some models), or HIGH

Saving energy
Along with using POWER SAVER(some models), there are many things you
can do to help save 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 tempera-
tures in the attic add to the air
conditioner's cooling load.
Try not to use heat-producing appli-
ances during the hottest part of the day.
Keep heat registers and cool-air re-
turns closed.
Use exhaust vent fans while cooking,
doing laundiry, or bathing.
Normal operating sounds
When your air conditioner is operating normally,you may hear sounds such as:
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 high efficiency compressor cycling on and off.

Troubleshooting
Y ou can solve many common air conditioner’s problems yourself, but when in doubt, please
consult with our authorized service center.
Air conditioner will not operate.
Check if
The power supply cord
is unplugged.
A household fuse has
blown or circuit breaker
has tripped.
The CONTROL is turned
to the “off ” position.
The local power has failed.
Then
Firmly plug the power supply cord into an active outlet
with proper voltage.
Replace the fuse or reset the circuit breaker. Make sure
the air conditioner is plugged into a properly grounded
outlet as described in the lnstallation lnstructions.
Turn the CONTROL to the “on” setting.
Wait for power to be restored.
Air conditioner blows fuses or trips circuit breakers.
Check if
Too many appliances
are being used on the
same circuit.
Time delay fuse or circuit breaker of the
wrong capacity is used.
Then
Unplug or relocate appliances that share the same
circuit.
Replace with a 15-amp time delay fuse or circuit breaker
of the correct capacity. See “Electrical requirements” in
the lnstallation lnstructions for the correct capacity.
An extension cord is
being used.
Y ou are trying to restart
the air conditioner too
soon after turning UNIT
CONTROL to “off”
Do not use an extension cord with this or any other
appliance.
Wait at least 3 minutes after turning CONTROL to “off”
before trying to restart the air conditioner.
Air conditioner seems to run too much.
Check if
The current air conditioner replaced an
older model.
The air conditioner is in
a heavily occupied
room or heat producing
appliances are in use in
the same room.
Then
The use of more efficient components may cause the
air conditioner to run longer than an older model, but
the total energy consumption will be less, Newer air
conditioners do not emit the “blast” of cold air you may
be accustomed to from older units, but this IS NOT an
indication of lesser cooling capacity or efficiency. Refer to the efficiency rating(EER) and capacity rating (in
BTUs/hr.) marked on the air conditioner.
Use exhaust vent fans while cooking or bathing and try
nt to use beat producing appliances during the hotteds
part of the day. A higher capacity air conditioner may
be required depending on the size of the room being
cooled.
