One hole is required for the air conditioner tubing, and
may be either on the left or right side. (Also see section
3-14. Preparing the Indoor Side Tubing.)
(1) Tape the full-scale installation diagram on the wall
at the location selected. Make sure the unit is
horizontal using a level or tape measure to
measure down from the ceiling. (Fig. 3-25)
(2) Determine if the hole is to be drilled at the left or
right hole location.
(3) Before drilling a hole, check that there are no
studs or pipes behind the determined location.
KH(S)3072R, KH(S)3672R
CAUTION
Avoid any area where electrical
wiring or conduit is located.
Also take this precaution if the
tubing goes through a wall at
any other location.
(4) Using a sabre saw, key hole saw or 3-5/32 in.
hole-cutting drill attachment, make a hole in the
wall. The required minimum hole diameter for
these models is 3-3/16 in. (Fig. 3-26)
(5) Measure the thickness of the wall from the inside
edge to the outside edge and cut PVC pipe at a
slight angle 1/4 in. shorter than the thickness of
the wall. (Fig. 3-27)
(6) Place the plastic cover over the end of the pipe,
(for indoor side only) and insert in the wall.
