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.
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.
CAUTION A slight heat odor may come from the unit

About the Controls on
the Air Conditioner
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.
How to Attach Front Grille to Cabinet
The front grille can be removed for cleaning or to check the model and serial numbers.
For your safety, you should attach the front grille as the following procedures.
Care and Maintenance
1. Pull down front grille from the cabinet
top.
2. Push front grille’s tips toward the cabinet
in order to insert front grille’s tabs into
the cabinet.
3. Open the inlet grille.
4. Tighten the screw through the front grille
into the plate of control box.

Troubleshooting Tips Save time and money!
Review the chart below first and you may not need to call for service.
Problem Possible Causes What To Do
■ 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.
■ Ice blocks the air flow and
stops the air conditioner
from cooling the room.
• 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.
• Set the mode control at Med Fan or High Cool with
the thermostat at 1or 2.

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
