Masonry Construction
See Figure 32 for dimensions of finished opening to cut
out or build into masonry wall. Seal outer case in place
with mortar or secure to wall with concrete nails driven
through sides of case.
NOTE: If securing case with concrete nails, pre-drill
holes in case before driving nails into wall.
Installation in Walls Exceeding
Outer Case Dimensions
Air conditioner must be installed so air flows freely
through side louvers to prevent overheating of
compressor and fan motor. If dimensions of wall restrict
airflow to louvers, wall opening must be modified by
chamfering vertical portions of outside opening, as
shown in Figures 35 and 36.
