Electrical Safety

IMPORTANT

(PLEASE READ CAREFULLY) FOR THE USER’S PERSONAL SAFETY, THIS APPLIANCE MUST BE PROPERLY GROUNDED The power cord of this appliance is equipped with a three- prong (grounding) plug. Use this with a standard three-slot (grounding) wall power outlet to minimize the hazard of electric shock. The customer should have the wall receptacle and circuit checked by a qualified electrician to make sure the receptacle is properly grounded.

DO NOT CUT OR REMOVE THE THIRD (GROUND) PRONG FROM THE POWER PLUG.

SITUATIONS WHEN THE APPLIANCE WILL BE DISCONNECTED OCCASIONALLY
Because of potential safety hazards, we strongly discourage the use of an adapter plug. However, if you wish to use an adapter, a TEMPORARY CONNECTION may be made. Use UL-listed adapter, available from most local hardware stores. The large slot in the adapter must be aligned with the large slot in the receptacle to assure a proper polarity connection.

CAUTION
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. The customer should have the circuit checked by a qualified electrician to make sure the receptacle is properly grounded. Disconnect the power cord from the adapter, using one hand on each. Otherwise, the adapter ground terminal might break. DO NOT USE the appliance with a broken adapter plug.

SITUATIONS WHEN THE APPLIANCE WILL BE DISCONNECTED OFTEN.
Do not use an adapter plug in these situations. Unplugging the power cord frequently can lead to an eventual breakage of the ground terminal. The wall power outlet should be replaced by a three-slot (grounding) outlet instead.

WARNING: This product contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. Wash hands after handling.

Installation

Remove packing materials from the wall sleeve and tape from the air conditioner.

INSTALLATION REQUIREMENTS
If you use an existing wall sleeve, you should measure its dimensions. Install the new air conditioner according to these installation instructions to achieve the best performance. All wall sleeves used to mount the new air conditioner must be in good structural condition and havearear grille to securely attach the new air conditioner.
