WALL
INSTALLATION
To install
the
room
air
conditioner
in the
wall,
perform
the
following
procedure:
1. Remove
air conditioner
from shipping
box.
Do not install
window
installation
parts.
2. Determine
the location
for air conditioner.
Make sure there
is adequate
clearance
on the inside and outside
of the wall.
Ensure
that the power
cord will reach the available
socket
without
an extension
cord. Air conditioner
can be installed
in walls up to 7" 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
•
Faces
the
area to be
cooled
and
is not
blocked
by
obstructions
•
Allows
unblocked
airflow
from rear (outside)
of installed
air conditioner
3. The
following
parts
will
need
to
be
provided
by
the
installer:
•
wood
frame
•
wood
shims
•
wood
screws (no. 10, 1" long)
4. Working
from
the inside
of the room,
find
a wall
stud
nearest
the center
of the area where the air conditioner
will
be installed.
This can be determined
by sounding
walls or
using a stud finder.
5. Cut or knock out a hole on each side of the center stud. (See
Fig. 22.)
IMPORTANT:
Read
entire
instructions
before
cutting
hole
in
wall.
6. Measure
between
the inside
edges
of every
other
stud as
shown
in Fig. 22
7. Follow
all local building
codes when building
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 conditioner
is installed
and is used to secure
the
air conditioner
to the wall.
The
depth
of the frame
should
approximately
match
the depth
of the wall.
The
thickness
of the
frame
will
need
to
be
added
to the
dimensions
to determine
the size of the hole in the wall.
IMPORTANT:
Be sure to measure
air conditioner
to check
size
before constructing
frame.
For example,
if using
3/4" thick
wood
for the frame,
the hole
would
need to be: 20-1/2"
+ 3/4" + 3/4" = 22" wide.
IMPORTANT:
If thickness
of the wall covers
top and side vents
of the air conditioner
when
it is installed,
the outer portion
of the
wall opening
must be widened.
The top and side vents must
be
clear and uncovered.
8. After the frame
has been constructed,
check to make
sure
that the air conditioner
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
frame into hole in wall. Make sure frame
is
properly
secured.
Fill in the space
between
the frame
and
the studs with wood
shims
(spacers).
Nails spacers
to studs.
If required,
provide
studs around
entire frame
to reinforce
stability
of wall (see Fig. 24).
