hose and drain cap" on page 14.)

3-2. Make a Hole

(1) Place the rear panel from the indoor unit on the wall
at the location selected. Make sure the panel is hori-
zontal, using a carpenter's level or tape measure to
measure down from the ceiling. Wait until after cut-
ting the hole before attaching the rear panel to the
wall.
(2) Determine which side of the unit you should make
the hole for tubing and wiring. (Fig. 9)
NOTE
In the case of left-rear tubing, use the measurement
points 2-3/8" (60 mm) from the edge of the rear panel for
precise placement of the hose outlet. (Fig. 9)
(3) Before making the hole, check carefully that no
studs or pipes are directly run behind the spot to be
cut.
Also avoid areas where elec-
