INSTALLATION

Features and Installation

1. To prevent vibration and noise, make sure the unit is installed securely and firmly

2. Install the unit where the sunlight does not shine directly on the unit.

3. The outside of the cabinet must extend outward for at least 28cm (11") and there should be no obstacles, such as a fence or wall, within 50.8cm (20") from the back of the cabinet because it will prevent heat radiation of the condenser. Restriction of outside air will greatly reduce the cooling efficiency of the air conditioner.

CAUTION: All side louvers of the cabinet must remain exposed to the outside of the

structure.

4. Install the unit a little slanted so the back is slightly lower than the front (about 12.7mm (1/

2")).

This will force condensed water to flow to the outside.

5. Install the unit with the bottom about 76.2cm (30")~152.4cm (60") above the floor level.

Window Requirements

NOTE: All supporting parts should be secured to firm wood, masonry, or metal.

This unit is designed for installation in standard double hung windows with actual opening widths from 55.88cm (22") to

91.44cm (36").

The top and bottom window sash must open sufficiently to allow a clear vertical opening of 38cm (15") from the bottom of the upper sash to the window stool.

Features and Installation

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 (Fig. 12) 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.

A. SITUATIONS WHERE THE APPLIANCE

WILL BE DISCONNECTED ONLY 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 (Fig. 13). 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.

B. SITUATIONS WHERE 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.
