How to Install

REWORD: Top Rail and Sliding Panels at each side are offset to provide the proper pitch of 5/16″ to the rear of the air conditioner.

1. Place unit on the floor, a bench or a table. There is a Left and Right Window Filler 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 Accordion Panel in one hand and gently pull back the center to free the open end. See Figure 3.
   

B. Slide the free end of the panel into the cabinet as shown in Figure 4. 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. Figure 5.

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

2. Keeping a firm grip on the air conditioner, carefully 2 place the unit into the window opening so the bottom of the air conditioner frame is against the window sill (FIG. 6). Carefully close the window behind the top rail of the unit. (It is suggested to keep a downward angle so accumulated rainwater can drain out from the backside of the unit.)
3. Extend the side panels out against the window frame (FIG. 7).

4. Place the frame lock between the frame extensions and the window sill as shown (Fig. 8). Drive 3/4″ (19 mm) locking screws through the frame lock and into the sill (FIG. 9). NOTE: To prevent window sill from splitting, drill 1/8″ (3 mm) pilot holes before driving screws.

5. Drive 1/2″ (12.7mm) locking screws through frame holes into window sash (FIG. 10/11).
6. To secure lower sash in place, attach right angle sash lock with 3/4″ (19 mm) screw as shown (FIG. 12).
7. Cut foam seal and insert in space 7 between the upper and lower sashes (FIG. 13).

If AC is Blocked by Storm Window

Add wood as shown in FIG. 14, or remove the storm window before the air conditioner is installed.

If the storm window frame must remain, be sure the drain holes or slots are not caulked or painted shut. Accumulated rainwater or condensation must be allowed to drain out.

Removing AC From Window

• Turn AC off, and disconnect the power cord.
• Remove sash seal from between windows and unscrew safety lock.
• Remove screws installed through frame and frame lock.
• Close  (slide) side panels into frame.
• Keeping a firm grip on the air conditioner, raise the sash and carefully“rock” the air conditioner backward to drain any condensate water in the base of the unit. Be careful not to spill any remaining water while lifting the unit from the window. Store parts WITH air conditioner.

AIR CONDITIONER USE

Operating your air conditioner properly helps you to obtain the best possible results.
This section explains proper air conditioner operation.
IMPORTANT:

• If you turn off the air conditioner, wait at least 3 minutes before turning it back on. This prevents the air conditioner from blowing a fuse or tripping a circuit breaker.
• Do not try to operate your air conditioner in the cooling mode when the outside temperature is below 65°F (18°C). The inside evaporator coil will freeze up, and the air conditioner will not operate properly.

NOTE: In the event of a power failure, your air conditioner will operate at the previous settings when the power is restored.
