2. Plug in the power plug properly.
3. Use a dedicated circuit.
4. Do not use an extension cord.
5. Do not start/stop operation by plugging/unplugging the power cord.
6. If the cord/plug is damaged, replace it with only an authorized replacement part.
1. Being exposed to direct airflow for a long time may be hazardous to your health. Do not expose
occupants, pets, or plants to direct airflow for a long time.
2. Due to the possibility of oxygen deficiency, ventilate the room when using the appliance together with
stoves or other heating devices.
3. Do not use this air conditioner for non-specified special purpose (e.g. preserving precision devices,
food, pets, plants, or art objects). Such use may damage your properties.
1. Do not touch the metal parts of the unit when removing the filter. Injury can occur.
2. Do not use water to clean inside the air conditioner. Exposure to water can destroy the insulation,
leading to electric shock.
3. When cleaning the unit, first make sure that the power and breaker are turned off. The fan rotates at a
very high speed during operation. There is a possibility of injury if the unit’s power is triggered while

To minimize the risk of electric shock, you must alway plug into a grounded oulet.
WARNING: Do not cut or remove the grounding prong from the
power plug.
WARNING: 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.
WARNING: If you have any doubt whether the air conditioner is
properly grounded, have the wall receptacle and circuit checked by

Electrical Safety
We strongly discourage the use of an adapter due to potential safety hazards. For temporary
connections, use only a UL-listed 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.
WARNING: 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.
