3. How to Install the Indoor Unit
3-1. Remove the Rear Panel from the Unit
(AWMI28AHL)
(1) Remove and discard the set screw on the rear
panel. (Fig. 5a)
(2) Press the 2 ▲▲ marks on the frame cover and disen-
gage the stationary tabs from the frame. (Fig. 6a)
(3) Remove the rear panel.
(AWMI36/50AHL)
First, remove the rear panel from the indoor unit.
Remove the screws attaching the panel and push up
the attachment tabs to permit a slight space, then com-
pletely remove the panel.
(The removed screws are no longer needed.)
Tubing can be extended in 5 directions as shown in
Fig. 6a. 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, refer to “Switching drain
hose and drain cap” on page 13.)
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 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. (Figs. 7a & b)
In the case of left-rear tubing, use the outside ▼▼ mark
for precise placement of the hose outlet. (Figs. 7a & b)
(3) Before making the hole, check carefully that no studs
or pipes are directly run behind the spot to be cut.
The above precautions are also applicable if tubing
goes through the wall in any other location.
