3-12. 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 measure 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. 3-34)

N OTE
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. 3-34)
(3) Before making the hole, check carefully that no studs or
pipes are directly run behind the spot to be cut.
SUPPLEMENT
CAUTION
Also avoid areas where electrical wiring or conduits are
located.
The above precautions are also applicable if tubing goes
through the wall in any other location.
(4) Using a sabre saw, key hole saw or hole-cutting drill
attachment, cut a hole in the wall. (Fig. 3-35)

3-13. Install the Rear Panel on the Wall

Be sure to confirm that the wall is strong enough to suspend the
unit.
NOTE
Be sure to install the unit within the range of the wall.
If Wooden Wall
(1) Attach the rear panel to the wall with the 8 screws
provided. (Fig. 3-38)
Fig. 3-38
If you are not able to line up the holes in the rear panel
with the beam locations marked on the wall, use rawl plugs
or toggle bolts to go through the holes on the panel or drill
5 mm dia. holes in the panel over the stud locations and
then mount the rear panel.
(2) Double check with a carpenter's level or tape measure
that the panel is level. This is important to install the unit
properly. (Fig. 3-39)
Fig. 3-39
(3) Make sure the panel is flush against the wall. Any space
between the wall and unit will cause noise and vibration.
