Step 1—Make Opening in Wall
Make an opening approximately 26-1/2 x 29 in. in a wall as close
to the cooling unit as possible. Build a frame to support the
condensing unit. (See Fig. 2.)
1. Insert condensing unit with frame into the wall opening.
2. Extend unit approximately 1 in. beyond outside (finished) wall
and tilt to the outside to allow rainwater to drain off. (See Fig.
3.)
3. Fasten unit to frame with metal straps.
4. Use flashing under unit and caulk all edges to provide
weathertight seal. (See Fig. 3.)
