Air Directional Louvers:
Louvers allow directing airflow UP/DOWN (some models) and Left/Right. Horizontal louvers can be pivoted, and levers moved side-to-side for desired direction.
Installation Instructions:
Designed for standard double-hung windows with opening widths of 23 to 36 inches. A clear vertical opening of 14" (35.6cm) for 5000-8000Btu/h models or 15-1/2" (39.4cm) for 10000-12000Btu/h models is required. The rear of the AC must be outdoors.
- Tools Needed: Phillips screwdriver, drill (for pilot holes).
- Top Rail Attachment (for <10000Btu/h models only): Remove the top rail from packaging, align holes with the unit's top, and secure with 3/8" screws. All four screws must be securely fastened for safety.
- Pitch: Top rail and sliding panels are offset to provide a 5/16" pitch to the rear for condensed water drainage.
- Accordion Panel Installation:
- Place the unit on a flat surface. Ensure left and right window filter panels are on the proper side, with the flange facing into the room.
- Hold the accordion panel, gently pull back the center to free the open end.
- Slide the open end panel into the side cabinet, then slide it down, ensuring enough space for the frame's top and bottom to slip into the cabinet rails.
- Ensure the panel sits securely in the frame channel by making slight adjustments. Slide the top and bottom ends of the frame into the cabinet rails.
- Repeat for the other side.
- Unit Placement: Keep a firm grip, place the unit into the window opening so the bottom frame is against the window sill. Close the window behind the top rail.
- Side Panel Extension: Extend the side panels against the window frame.
- Frame Lock: Place the frame lock between the frame extensions and the window sill. Drive 3/4" (19mm) or 1/2" (13mm) locking screws through the frame lock and into the sill. Drill 1/8" (3mm) pilot holes to prevent sill splitting.
- Window Sash Screws: Drive 1/2" (13mm) locking screws through frame holes into the window sash.
- Sash Lock: Attach a right-angle sash lock with a 3/4" (19mm) or 1/2" (13mm) screw to secure the lower sash.
- Foam Seal: Cut and insert foam seal in the space between upper and lower sashes.
- Storm Window Obstruction: If a storm window blocks the AC unit, add wood as shown in Fig. 13 or remove the storm window. Ensure drain holes/slots are not caulked or painted shut.
- Tilt: After installation, ensure the air conditioner is tilted 3-4 degrees to the outside for water drainage and cooling efficiency.
Removing AC From Window:
- Turn off and disconnect power cord.
- Remove sash seal and unscrew safety lock.
- Remove screws from frame and frame lock.
