When left tubing is to be done, switch the drain
hose and drain cap. (For details, refer to "Switching
drain 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 horizontal, using a carpenter's level or tape mea-
sure to measure down from the ceiling. Wait until
after cutting 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. 9a or 9b)
NOTE
In the case of left-rear tubing, use the measurement
points from the edge of the rear panel for precise
placement of the hose outlet. (Fig. 9a or 9b)
(3) Before making the hole, check carefully that no
studs or pipes are directly run behind the spot to
be cut.
CAUTION
The above precautions are also applicable if tub-
ing goes through the wall in any other location.
