size. First, measure the distance from inside one window channel to the inside of the other channel and subtract l/4�. Now subtract the width of the air conditioner and divide by 2. This will give you the width to cut each filler board. Be sure to cut the filler boards on the sides opposite the holes. Because the filler boards will be equal in width, they will automatically center your air conditioner in your window.

seal strips and attach filler boards. Determine which will be your left and right filler boards. The holes on each board should align with the holes in the side mounting angles. Each filler board should also extend about l/2� above the top edge of the air conditioner cabinet, Now apply 3/8�-wide seal strips on the roomside of each filler board as shown in Figure 35 (i.e. along with bottom edge and window channel edge). Also place a seal strip along the top outside edge of each filler board. Now attach the filler boards to the side mounting angles with the sheet metal screws. Tighten the screws only loosely so the filler boards can be moved back and forth.

channel. Extend the mounting slides outward into the window channels on both sides (see Figure 37). Pull the air conditioner toward you to position the side mounting slides as far forward in the window channels as possible. Now mark and make a 3/32� pilot hole for each wood screw used to secure the slides in the window channels. CAUTION: BE SURE UNIT DOES NOT FALL OUT OF WINDOW.
