How to Install

NOTE:
The top Rail and Sliding Panels at each side are offset to provide the proper pitch to the rear (5/16″). This is necessary for proper condensed water utilization and drainage. If you are not using the Side Panels for any reason, this pitch to the rear must be maintained!

1. Place the 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.
   • Hold the Accordion Panel in one hand and gently pull back the center to free the open end. See Figure 3.
   • 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.
   • 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
2. Keep a firm grip on the air conditioner, and carefully 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. (Suggest keeping a downward oblique, to let accumulated rainwater drain out, from the back side of the unit bottom.)
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 the 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 the window sash (FIG. 10/11).
6. To secure the lower sash in place, attach the right angle sash lock with 3/4″ (19 mm) screw as shown (FIG. 12).
7. Cut foam seal and insert in the space between the upper and lower sashes (FIG. 13).

If AC is Blocked by Storm Window
Add wood as shown in FIG. 14, or remove storm window before air conditioner is installed.

If Storm Window Frame must remain, be sure the drain holes or slots are not caulked or painted shut. Accumulated Rain Water or Condensation must be allowed to drain out.

Removing AC From the Window

• Turn AC off, and disconnect the power cord.
• Remove the sash seal from between windows, and unscrew the safety lock.
• Remove screws installed through the frame and frame lock.
• Close (slide) side panels into the 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 an 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.

CARE AND CLEANING

Clean your air conditioner to keep it looking new and to minimize dust build- up.

Air Filter Cleaning
The air filter should be checked at least once every month to see if it needs cleaning. Trapped particles and dust can build up in the filter and may decrease airflow as well as cause the cooling coils to accumulate frost. To clean the air filter:

1. Take off the power plug, then remove the filter by sliding it out from the front right side of the air conditioner. (See Fig .15)
2. Wash the filter using liquid dish soap and warm water. Rinse the filter thoroughly. Gently shake the filter to remove excess water.
3. Let the filter dry completely before placing it into the air conditioner.
4. If you do not wish to wash the filter, you may vacuum the filter to remove the dust and other particles.

Wear and Tear
To minimize wear and tear on the air conditioner, always wait at least 3 minutes before changing modes. This will help prevent the compressor from overheating and the circuit breaker from tripping.

Cabinet Cleaning

To clean the air conditioner cabinet:

• Unplug the air conditioner to prevent shock or a fire hazard. The cabinet and front panel of the air conditioner may be dusted with an oilfree cloth or washed with a cloth dampened in a solution of warm water and mild liquid soap. Rinse thoroughly with a damp cloth and wipe dry.
• Never use harsh cleaners, wax or polish on the cabinet front.
• Be sure to wring excess water from the cloth before wiping around the controls. Excess water in or around the controls may cause damage to the air conditioner.

Winter Storage
