6-45. Remove the Rear Panel from the Unit
(1) Remove and discard the set screw on the rear panel.
(Fig. 1-144)
(2) Press the 2 marks on the frame cover and disengage the
stationary tabs from the frame. (Fig. 1-145)
(3) Remove the rear panel by grasping the sections shown in
Fig. 1-146 and pulling it in the direction shown by the arrow.
NOTE
Tubing can be extended in 6 directions as shown in Fig. 1-148.
Select the direction you need providing the shortest run to the
outside unit.
When left tubing is to be done, switch the drain hose and
drain cap. (For details, see the section "Switching drain hose
and drain cap" on page 1-168.)
6-46. 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. 1-149)
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. 1-149)
(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
CAUTION electrical wiring or conduits
are located.
The above precautions are also applicable if tubing goes
through the wall in any other location.
