(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

(2) Determine which side of the unit you should make the hole
for tubing and wiring. (Fig. 2-111)
NOTE

In the case of left-rear tubing, use the measurement points
158 mm from the marked position on the rear panel for precise
placement of the hose outlet. (Fig. 2-111)
(3) Before making the hole, check carefully that no studs or
pipes are directly run behind the spot to be cut.
