WARNING
Falling Object Hazard
Not following Installation Instructions
for mounting your air conditioner can
result in property damage, injury, or
death.
STEP 1 Check the window sill and frame to be sure they are in good condition and firmly anchored to the wall. Repair if necessary.
STEP 2 CABINET MOUNTING: Raise the lower window sash 1/4” more than the height of the cabinet. Carefully slide the cabinet through
the open window until the sill plate channel rests behind the window sill and the top support angle (Item #5) rests against the
window (See Figure 17). Center the cabinet side to side and drill three (3) 5/32” diameter pilot holes into the window sill using
the holes in the cabinet sill plate as a guide. Install three (3) #12A x 2” long screws (Item #4) (See Figure 17).
Figure 17
STEP 3 OUTSIDE SUPPORT MOUNTING: Assemble the support brackets (Item #1) to the bottom rails of the cabinet with four (4) 10-24
1” long screws (Item #2) and four (4) 10–24 flat nuts (Item #3). Adjust the support brackets to bring the bottom pads in contact
with the wall surface. (See Figure 18.)
A 1” x 4” or 2” x 4” SPACER SHOULD BE USED BETWEEN THE WALL AND THE SUPPORT BRACKETS WHEN
INSTALLED ON ALUMINUM OR VINYL SIDING). Drill 5/32” (4 mm) diameter pilot holes, and secure the brackets to the wall
with two (2) #12A x 2” long screws (Item #4). Adjust the support brackets to provide an approximate 3/8” (10 mm) down slope
towards the outside for drainage. Tighten all screws. (See Figure 18).
