(i.e. the higher number, the greater cooling)
• FOR NORMAL COOLING
1. Turn the Operation Knob to the High Cool from
the Low Cool setting.
2. Set the Thermostat control to the desired
temperature mark 5 (the mid-point is a good
starting position). If the room temperature is not
satisfactory after a reasonable time, adjust the
control to a cooler or warmer setting, as
appropriate.
• FOR MAXIMUM COOLING
1. Turn the Operation Knob to the High Cool setting.
2. Set the Thermostat control to the largest
temperature mark.

necessary, in accordance with your temperature preference.
The thermostat automatically controls cooling or heating, but the fan
runs continuously whenever the air conditioner is in operation. If the
room is too warm, turn the thermostat control clockwise. If the room is
too cool, turn the thermostat control counterclockwise.
• THE AIR CONDITIONER
This automatically controls the temperature of the
indoor air.
The compressor will turn on and off to keep the room
at the setting temperature.
In the heating operation, the electric heater will turn on
and off to keep the room at the setting temperature.
• HEAT PUMP MODELS
When the outdoor temperature is lower than
-4°C (24°F), the electric heater will turn on instead of
the heat pump.
CAUTION
When the air conditioner has been performed its
cooling or heating operation and is turned off or
set to the fan position, wait at least 3 minutes
before resetting to the cooling operation again.
About the Controls on
the Air Conditioner
A slight heat odor may come from the unit
when first switching to HEAT after the
cooling season is over. This odor, caused
by fine dust particles on the heater, will
disappear quickly. This is harmless.

Additional controls and important information.
Ventilation
The ventilation lever is located in the right of the air discharge.
The ventilation lever must be in the CLOSE position in order to
maintain the best cooling conditions.
When fresh air is necessary in the room, set the ventilation lever to
the OPEN position.

Care and Maintenance
TURN THE AIR CONDITIONER OFF AND REMOVE THE PLUG FROM THE POWER OUTLET.
Air Filter Cleaning
The air filter should be checked at least twice a month to see if cleaning is necessary.
Trapped particles in the filter will build up and block the airflow. This reduces the cooling
capacity and also causes an accumulation of frost on the cooling coils.
If the filter becomes turn or damaged you should replace
immediately. Replacement filters are available from your
salesperson, dealer, and the authorized customer service
centers.
1. Open the inlet grille downward by pulling out the top of the
inlet grille.
2. Remove the air filter from the front grille assembly by
pulling the air filter up slightly.
3. Wash the filter using lukewarm water below 40°C (104°F).
4. Gently shake the excess water from the filter completely.
Replace the filter.

Troubleshooting Tips Save time and money!
Review the chart below first and you may not need to call for service.
Normal Operation
• You may hear a pinging noise caused by water being picked up and thrown against the condenser
on rainy days or when the humidity is high. This design feature helps remove moisture and improve
efficiency.
• You may hear the thermostat click when the compressor cycles on and off.
• Water will collect in the base pan during high humidity or on rainy days. The water may overflow
and drip from the outdoor side of the unit.
• The fan may run even when the compressor does not.
Abnormal Operation
Problem Possible Causes What To Do
Air conditioner
does not start
Air conditioner
does not cool as it
should
■
The air conditioner is
unplugged.
■
The fuse is blown/circuit
breaker is tripped.
■
Power failure.
■
Airflow is restricted.
■
The THERMOSTAT may
not be set high enough.
■
The air filter is dirty.
■
The room may have been
hot.
■
Cold air is escaping.
■
Cooling coils have iced up.
• Make sure the air conditioner plug is pushed
completely into the outlet.
• Check the house fuse/circuit breaker box and
replace the fuse or reset the breaker.
• If power failure occurs, turn the mode control to OFF.
When power is restored, wait 3 minutes to restart the
air conditioner to prevent tripping of the compressor
overload.
• Make sure there are no curtains, blinds, or furniture
blocking the front of the air conditioner.
• Turn the knob to a higher number. The highest
setting provides maximum cooling.
• Clean the filter at least every 2 weeks.
See the operating instructions section.
• When the air conditioner is first turned on,
you need to allow time for the room to cool down.
• Check for open furnace floor registers
and cold air returns.
• Set the air conditioner's vent to the closed position.
• See Air Conditioner Freezing Up below.
