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 the 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 ensure a proper polarity connection.
• 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. 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.

Tools Needed

How to Install the Unit

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

2. Install the unit out of direct sunlight.

3. There should be no obstacles, such as a fence or wall, within 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
   DO NOT cover or block any of the side and top louvers. All side louvers of the cabinet must remain exposed to the outside of the structure and unobstructed.

4. Install the unit slightly tilted so the back is slightly lower than the front (about 1/4”). This will force condensed water to flow to the outside.

5. Install the unit with the bottom between 30”~ 60” above the floor level.

Window Requirements
This unit is designed for installation in standard double-hung windows with actual opening widths from 22” to 36”. The top and bottom window sashes must open sufficiently to allow a clear vertical opening of 13” from the bottom of the upper sash to the inside sill.

NOTE

• All supporting parts should be secured to firm wood, masonry, vinyl, fiberglass, or metal.
• This product is a window air conditioner. As such, a standard single-hung or double-hung window is required for proper installation. Nonwindow installations, including using sleeves or wall openings, and other installation methods are not recommended.

Storm Window Requirements

1. Windows that include a storm window frame may prevent the air conditioner from tilting down toward the outside to drain properly. For proper drainage, attach a 1” x 2” piece of wood to the inner sill, trimmed to a length which fits inside the window frame. The top of the wood shim must be at least 3/4” higher than the top of the storm window frame. Attach the wood securely to the sill with nails or screws.
2. If necessary, attach another 1” x 2” wood strip flush against the back of the inner sill. This will raise the L bracket, as shown in the drawing.

Preparation of the Chassis

1. Assemble two supporters with upper guide. Align holes between the upper guide and the top of the cabinet and then install it with 3 type A screws. NOTE
   The feature may be changed according to the type of model.

2. Extend the curtains in the curtain panels and insert the edges into the brackets on either side of the cabinet. Insert the top and bottom rails on the curtain guides into the upper and lower panel guides on the cabinet NOTE
   The feature may be changed according to the type of model.

3. Cut the window sash seals to the proper length. Peel off the backing and attach the adhesive-backed foam to the underside of the window sash and bottom of window frame.

4. Open the window and draw a center line on the center of the inner sill. Then mark lines 8” to the left and right of the center line.

5. Install the L bracket behind the inner window sill as shown. Use the 2 type A screws provided

NOTE
The bracket helps to hold unit securely in place. Be sure to place bracket edge flush against back of inner sill.

Unit Installation

CAUTION
During the following step, hold unit firmly until window sash is lowered to top channel behind side panel frames. Personal injury or property damage may result if unit falls from window.

1. Set the air conditioner in the window so that is centered. Place the air conditioner so that front edge of the bottom guide is against the back edge of the sill. Bring the window down so that the front edge of the upper guide is in front of the window. Make sure that air conditioner is level or tilting slightly to the outside.

2. Extend the guide panels to fill the window opening and use 5 type B screws to secure them to the window. NOTE
   The feature may be changed according to the type of model.

3. Cut the non-adhesive foam strip to the proper length and insert it between the upper window sash and the lower window sash.

4. To prevent broken glass or damage to windows, on vinyl or other similarly constructed windows, attach the L bracket with a type A screw.

Cleaning the Air Filter

1. Remove the air filter from the front grille by pulling the filter forward and then up slightly.
2. Wash the filter using lukewarm water below 40 °C (104 °F).
3. Gently shake the excess water from the filter and replace.

NOTE
The feature may be changed according to the type of model.

Cleaning the Air Conditioner

• Remove dust from the air inlet and outlet using a vacuum cleaner.
• Wipe the front grille and inlet grille with a cloth dampened in a mild detergent solution.
• Wash the cabinet with mild soap or detergent and lukewarm water, then polish using liquid appliance wax.

NOTE

• To ensure continued peak efficiency, the condenser coils (outside of unit) should be checked periodically and cleaned if clogged with soot or dirt from outside air.
• For repair and maintenance, contact an Authorized Service Center. See the warranty page for details or call 1-800-243-0000. Have your model number and serial number available. They can be found on the side of the cabinet. Record them for future reference.
• The feature may be changed according to the type of model.
