Electrical Safety
Electrical Safety
• This appliance must be properly grounded.
To minimize the risk of electric shock, you must always 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.
This appliance should be installed in accordance with national wiring regulations. This manual acts as a
guide to explaining product features.

Maintenance and Service
Outdoor Unit
The heat exchanger coils and panel vents of the outdoor unit should be checked regularly.
If clogged with dirt or soot, the heat exchanger
and panel vents may be professionally steam cleaned.
NOTE
Dirty or clogged coils will reduce the operating efficiency of the system and cause higher operating costs.
Operation Tips!
Do not overcool the room.
Keep blinds or curtains
closed.
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 as much as
possible to keep the cool
air in the room.
Keep the room temperature
uniform.
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.
Adjust the vertical and horizontal
airflow direction to ensure a
uniform temperature in the room.
Ventilate the room
occasionally.
Since windows are kept
closed, it is a good idea
to open them and
ventilate the room now
and then.
Use high fan speed
for effective and fast
cooling.
The unit gives its rated
cooling capacity when the
fan speed is high.
