■
Right-side tubing
(1) Shape the refrigerant tubing so that it can easily go
into the wall hole. (Fig. 24)
(2) Push the wiring, refrigerant tubing, and drain hose
through the hole in the wall. Adjust the indoor unit so
it is securely seated on the rear panel.
(3) Carefully bend the tubing (if necessary) to run along
the wall in the direction of the outdoor unit and then
tape as far as the fittings.
(4) Connect the refrigerant tubing to the outdoor unit.
(After performing a leak test on the connecting part,
insulate it with tubing insulation. (Fig. 26)) Also, refer
to Section 4-3. Connecting Tubing between Indoor
and Outdoor Units.
(5) Assemble the refrigerant tubing, drain hose, and
inter-unit wiring as shown in Fig. 27.

CAUTION
If using a stepladder, be careful
to keep your balance and not
fall off. To prevent the unit
from damage and avoid per-
sonal injury, ask for someone’s
help when feeding the tubing
through the hole because the
unit is heavy and difficult to
hold in place.
CAUTION
The air conditioner’s perfor-
mance will be deteriorated if a
tube is crushed. To prevent
crushing of the tube, avoid
sharp bends. Use a pipe bend-
ing tool to bend the tube.
