Installation Overview
Accessories
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 where the sunlight dose not shine directly on the unit.
3. The outside of the cabinet must extend outward for at least 12" and 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.
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: This prodcut is a WINDOW AIR CONDITIONER. As such, a standard single-hung or double-hung window is required for proper installation. No-window installations, including using sleeves, holes in walls, and other installations are not recommended.
Clearance
Proper clearance enhances the cooling efficiency of the product.
- If a storm window presents interference, fasten a 2” wide wood strip to the inner window sill across the full width of the sill. The wood strip should be thick enough to raise the height of the window sill so that the unit can be installed without interference by the storm window frame.
- (See drawing.) The top of the wood strip on the inside sill should be approximately ¾” higher than the storm window frame or wood strip on the outside sill to help condensation to drain properly to the outside.
- If necessary, install a second wood strip (same thickness as first strip) in the center of sill flush against the back off the inner sill. This will raise the L bracket as shown in the drawing.
Preparation of Unit
1. Insert the top and bottom rails of the curtain panels into the upper and lower panel guides.
2. Fasten the curtain
3. Cut the window sash seals to the proper length. Peel off the backing and attach the Foam-PE(Adhesive backed) to the underside of the window sash and bottom of window frame.
4 Open the window and mark center line on the center of the inner sill.
5. Install the L bracket behind the inner window sill, with short side of bracket as shown. Use the 2 Type A screws provided
Unit Installation
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 using 4 Type B screws to secure them.
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. Attach the window locking bracket with a type A screw.
NOTE: Fasten the remaining L bracket to the outer window sash with 1 type A screw as shown
5. Remove the screw form the right side of cabinet. Fasten the support bracket using a removed from the air conditioner cabinet. Attach the support bracket to the inner window sill with a Type B screw.
6. Cut the adhesive-backed heatproof foam to match the size of the curtain panels. Remove the backing from the heatproof foam and attach it to the curtain panels. Heatproof foam improves the cooling capability of the air conditioner.
NOTE: See the 'Electrical Data' section for information on attaching the power cord to an electrical outlet.
