Installation Instructions

Your air conditioner is designed to install in standard double hung windows with opening widths of 23 to 36 inches (584mm to 914mm)

1. PREPARE THE WINDOW

Lower sash must open sufficiently to allow a clear vertical opening (see dimension H in Table 1). Side louvers and the rear of the AC must have clear air space to allow enough airflow through the condenser for heat removal. The rear of the unit must be outdoors, not inside a building or garage.

CAUTION When handling unit, be careful to avoid cuts from sharp metal edges and aluminum fins on front and rear coils.

2. PREPARE THE AIR CONDITIONER

Before installing the unit, the top rail must be assembled on the unit.

A: Remove the air conditioner from the carton and place on a flat surface.

B: Remove top rail from the packaging material as shown in Fig. A.

C: Align the hole in the top rail with those in the top of the unit as shown in Fig. B.

D: Secure the top rail to the unit with the 3/8” (9.5mm) screws as shown in Fig. C.

WARNING For safety reasons, all four (4) screws MUST be securely fastened.

3. INSTALL THE ACCORDION PANELS

NOTICE The Top rail and Sliding Panels on each side are offset to provide the proper pitch to the rear of 5/16” (8mm). This is necessary for proper condensate management and drainage. If you are not using the side panels for any reason, this pitch to the rear must be maintained.

1. Place unit on the floor, a bench or a table. There is a left and right side accordion panel; be sure to use the proper panel for each side. When installed, the flange for securing the panel in place to the window sill will be facing into the room.

A. Hold the side panel in one hand and gently pull back the center to free the open end. See Fig. 1.

B. Slide the free and “I” section of the panel directly into the cabinet as shown in Fig. 2. Slide the panel down. Be sure to leave enough space to slip the top and bottom of the frame into the rails on the cabinet.

C. Once the panel has been installed on the side of the cabinet, make sure it sits securely inside the frame channel by making slight adjustments. Slide the top and bottom ends of the frame into the top and bottom rails of the cabinet. Fig. 3.

D. Slide the panel all the way in and repeat on the other side.

NOTICE If storm window blocks AC, see Fig. 11.

4. INSTALL AIR CONDITIONER

2. While keeping a firm grip on the air conditioner, carefully place the unit into the window opening so the bottom of the air conditioner frame is against the window sill (Fig. 5). Carefully close the window behind the top rail of the unit.

NOTICE Check that air conditioner is tilted back per dimension H (Fig. 5) (tilted about 3° to 4° downward to the outside). After proper installation, condensate should not drain from the overflow drain hole during normal use. Adjust the slope if otherwise.

3. Extend the side panels out against the window frame (Fig. 6).

5. SECURE AIR CONDITIONER

A. Place the frame lock between the frame extensions and the window sill as shown (Fig. 7A for Wooden windows), (Fig. 7B for Vinyl-Clad windows).

Drive 3/4” (19 mm) or 1/2” (12.7 mm) locking screws through the frame lock and into the sill.

NOTE: To prevent window sill from splitting, drill 1/8” (3 mm) pilot holes before driving screws.

B1: For wooden windows:

Drive 1/2” (12.7 mm) locking screws through the frame lock and into the sill (Fig. 8A).

NOTE: To prevent window sill from splitting, drill 1/8” (3mm) pilot holes before driving screws. Drive 1/2” (12.7mm) locking screws through frame holes into window sash (Fig. 8B/8C).

B2: For Vinyl-Clad windows:

Drive 1/2” (12.7 mm) locking screws through the top rail and into the window sash (Fig. 8B/8C).

NOTE: Before driving the screws, drill 5 holes into the window through the holes of the top rail and side panel frames as shown (Fig. 8B/8C).

C. Secure lower sash in place by attaching the sash lock with the 3/4” (19 mm) or 1/2” (12.7 mm) screw as shown (Fig. 9).

D. Cut Window sash seal foam and insert it in the space between the upper and lower sashes (Fig. 10).

If AC is Blocked by Storm Window

Add wood as shown in Fig. 11, or remove storm window before air conditioner is installed.
