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 Useof anAdapter

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 Useof anExtensionCord

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 guide acts as a guide to help to explain product features.
