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.
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.
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.

During Healthy Dehumidification Operation
oIf you select the dehumidification mode on the OPERATION MODE
SELECTION BUTTON, the product starts to run the dehumidification
function. It automatically sets the room temperature and airflow volume to the
best condition for dehumidification, based on the sensed current room
temperature.
In this case, however, the setting temperature is not displayed on the remote
controller and you are not able to control the room temperature either.
oDuring the healthy dehumidification function, the airflow volume is
automatically set according to the optimization algorithm responding to the
current room temperature status, so that the room condition is kept healthy
and comfortable even in the very humid season.
In this operation mode the actual setting temperature and
the fan speed are automatically set by the electronic control
logic based on the current room temperature. If you feel hot
or cold press the temperature setting buttons respectively for
more cooling or heating effect.

Operation Tips
Operate the air conditioner on Air
circulation mode (Refer to page 11) for 2
to 3 hours.
• This will dry out the internal mechanisms.
When air conditioner is not going to be
used for a long time. When the air conditioner is to be used again.
Turn off the circuit breaker, and
disconnect the power cable.
Remove the batteries from the Remote
Controller.
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.
Clean the air filter and install it in the
indoor unit.
(Refer to page 14~15 for cleaning filters.)
Check that the air inlet and outlet of the
indoor/outdoor unit are not blocked.
Do not overcool the room.
This is not good for the health
and wastes electricity.
Make sure that the doors
and windows are shut tight.
Avoid opening doors and
windows if possible to keep the
cool air in the room.
Keep blinds or curtains
closed.
Do not let direct sunshine enter
the room when the air
conditioner is in operation.
Clean the air filter regularly.
Blockages in the air filter reduce
the airflow and lower cooling
and dehumidifying effects.
Clean at least once every two
weeks.
Keep the room temperature
uniform.
Adjust the vertical and
horizontal airflow direction to
ensure a uniform temperature in
the room.
Ventilate the room
occasionally.
