sion cord An" conditioner can be installed in walls
up to 7 in thick Side louvers must never be
blocked Select a wall surface that:
• does not support major structural loads such as
the frame construction at ends of windows and
under truss-bearing points
• does not have plumbing or wiring routed inside
• is near existing electrical outlets or near where a
new outlet can be installed
• f_ees the area to be cooled and is not blocked by

Follow all local building codes when bmlding and
installing frame Build a wooden frame that will
be placed around the unit in the wall The frame
will reinforce the hole in the wall where the air
eonditioner is installed and is used to secure the
air conditioner to the wall The frame should have
an inner dimension of 20 5-in width by 14 8-in
height for 7;3KC 1OlP air conditioners or 22 8-in
width by 15 7-in height for 7;3K0 121P air condi-
tioners to ensure that the air conditioner will fit
inside the frame See Fig 21 The depth of the
frame should approximately match the depth of
the wail The thickness of the h'ame will need to
be added to the dimensions to determine the size
of the hole in the wail

make sure that the air eonditioner fits correctly
inside it If the frame is too tight or too loose,
adjust the size or re-construct
9 Measure the outer dimensions of the frame and
use those dimensions to cut the hole in the wall
Make sure the hole is level or condensate will not
drain properly
10 Install wooden h'ame into hole in wail Make sure
frame is properly secured. Fill in the space
between the fi'ame and the studs with wood shims
