WARNING: This appliance must be properly grounded.
The power cord of this appliance is equipped with a three-prong grounding plug.
To minimize the risk of electric shock, use the plug with a standard three-slot
grounding wall power outlet. If the power outlet does not include a grounding slot,
have a qualified electrician replace the outlet before you use the room air
conditioner.
WARNING: Changing the outlet without making the appropriate wiring
changes will create an unsafe condition that could result in fire or
electrical shock. Refer all such work to a licensed and qualified
electrician.
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 a
qualified electrician.

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.
