3-18. Removing the Rear Panel from the Unit
(1) Remove the set screws used to fasten the rear
panel to the indoor unit during transportation.
(2) Press up on the frame at the 2 locations shown by
the arrows in the figure at right, and remove the
rear panel.
Tubing can be extended in 4 directions as shown in
Fig. 3-61. Select the direction which will provide the
shortest run to the outdoor unit.
3-19. Selecting and Making a Hole
(1) Remove the rear panel from the indoor unit and
place it on the wall at the location selected. Fix the
rear panel and hook the unit onto it temporarily.
Make sure the unit is horizontal using a carpen-
ter’s level or tape measure to measure down from
the ceiling.
(2) Determine which notch of the rear panel should be
used. (Fig. 3-62)
(3) Before drilling a hole, check that there are no
studs or pipes behind the determined location.
The above precautions are also applicable if tub-
ing goes through the wall in any other location.
(4) Using a sabre saw, key hole saw or hole-cutting
drill attachment, make a hole (dia. 80 mm) in the
wall. (Fig. 3-63)
(5) Measure the thickness of the wall from the inside
edge to the outside edge and cut the PVC pipe at
a slight angle 6 mm shorter than the thickness of
the wall. (Fig. 3-64)
(6) Place the plastic cover over the end of the pipe (for
indoor side only) and insert in the wall. (Fig. 3-65)
The hole should be made at a slight downward gradi-
ent to the outside.
