Electrical Safety
Electrical Safety
• This appliance must be properly grounded.
To minimize the risk of electric shock, you must alway plug into a grounded oulet.
• Do not cut or remove the grounding prong from the power plug.
• Attaching the adapter ground terminal to the wall receptacle cover screw does not ground the appliance
unless the cover screw is metal and not insulated, and the wall receptacle is grounded through the
house wiring.
• If you have any doubt whether the air conditioner is properly grounded, have the wall receptacle and
circuit checked by a qualified electrician.
Temporary Use of an Adapter
We strongly discourage the use of an adapter due to potential safety hazards. For temporary connections,
use only a genuine adapter, available from most local hardware stores. Ensure that the large slot in the
adapter is aligned with the large slot in the receptacle for a proper polarity connection.
To disconnect the power cord from the adapter, use one hand on each to avoid damaging the ground
terminal. Avoid frequently unplugging the power cord as this can lead to eventual ground terminal damage.
• Never use the appliance with a broken adapter.
Temporary Use of an Extension Cord
We strongly discourage the use of an extension cord due to potential safety hazards. For temporary
situations, use only CSA certified and UL listed 3-wire grounded extension cords, rated 15 A, 125 V.
This appliance should be installed in accordance with national wiring regulations. This guide acts as a
guide to help to explain product features.

Common Problems and Solutions
Before calling for service
If you have problems with your air conditioner, read the following information and try to solve
the problem. If you cannot find a solution, turn off the air conditioner and contact your dealer.
Air conditioner does not operate
1. Ensure that the air conditioner is plugged into a proper outlet.
2. Check the fuse or circuit breaker.
3. Check whether the voltage is unusually high or low.
Air does not feel cold enough on the cooling setting
1. Ensure that the temperature settings are correct.
2. Check to see if the air filter is clogged with dust. If so, replace the filter.
3. Ensure that the air flow from the outside is not obstructed and that there is a clearance of
over 20" between the back of the air conditioner and the wall or fence behind it.
4. Close all doors and windows and check for any source of heat in the room.
Before calling for service, please review the following list of common problems and
solutions.
The air conditioner is operating normally when:
• You hear a pinging noise. This is caused by water being picked up by the fan on rainy days
or in highly humid conditions. This feature is designed to help remove moisture in the air
and improve cooling efficiency.
• You see water dripping from the rear of the unit. Water may be collected in the base pan in
highly humid conditions or on rainy days. This water overflows and drips from the rear of
the unit.
• You hear the fan running while the compressor is silent. This is a normal operational
feature.

Maintenance and Service
When the air conditioner is not going to be used for a long time.
When air conditioner is not going to be
used for a long time.
When the air conditioner is to be used again.
Operate the air conditioner on Air circulation
mode (Refer to page 23) for 2 to 3 hours.
Clean the air filter and install it in the indoor
unit.
(Refer to page 26 for cleaning filters.)
• This will dry out the internal mechanisms.
Turn off the circuit breaker, and disconnect
the plug.
Check that the air inlet and outlet of the
indoor/outdoor unit are not blocked.
CAUTION
Turn off the circuit breaker when the air conditioner
is not going to be used for a long time.
Dirt may collect and may cause a fire.
Remove the batteries from the remote
control.
Operation Tips
Do not overcool the room.
Keep blinds or curtains
closed.
Keep the room temperature
uniform.
This is not good for the health
and wastes electricity.
Do not let direct sunshine enter
the room when the air
conditioner is in operation.
Adjust the vertical and
horizontal airflow direction to
ensure a uniform temperature
in the room.
Make sure that the doors
and windows are shut tight.
Clean the air filter regularly.
Ventilate the room
occasionally.
Avoid opening doors and
windows as much as possible
to keep the cool air in the room.
Blockages in the air filter
reduces the airflow and lowers
the cooling and dehumidifying
effects. Clean at least once in
every two weeks.
Since windows are kept closed,
it is a good idea to open them
and ventilate the room now and
then.
