3-22. Preparing the Tubing
(1) Arrangement of tubing by directions
a) Right or left tubing
The corner of the right or left frame should be
cut with a hack saw or similar. (Fig. 3-72)
b) Right-rear or left-rear tubing
In this case, the corners of the frame do not
need to be cut.
(2) Be sure to insulate the part of the drain hose that
is run indoors, and the refrigerant tubing.
If these are not insulated, condensation may result
in dripping and damage to walls and furniture.
The flare nuts on the 73 type (only) are large;
therefore, use the supplied insulation material.
(3) To mount the indoor unit on the rear panel.
1. When installing the indoor unit, position the
indoor unit onto the installation tabs on the
upper part of the rear panel. (Fig. 3-73)
2. Press on the air outlet to hold it in place, and
press the lower part of the indoor unit until a
“click” sound is heard and the indoor unit is
securely fastened to the installation tabs on the
lower side of the rear panel. (Fig. 3-74)
Raising the clamp to lift up the indoor unit will facili-
tate this work. (Fig. 3-75)
To remove the indoor unit, press up on the 2 loca-
tions (
▲▲ marks) on the lower part of the unit frame
to disconnect the installation tabs. Refer to Section
3-18. “Removing the Rear Panel from the Unit
(Fig. 3-60).”
Then lift up the indoor unit to remove it.
3-23. Shaping the Tubing
Right-rear tubing
(1) Shape the refrigerant tubing so that it can easily
go into the hole. (Fig. 3-76)
(2) After performing a leak test, wrap both the refriger-
ant tubing and drain hose together with insulating
tape.
The drain hose should be positioned below the
refrigerant tubes, and should be given sufficient
space so that no strong tension is applied to it.
(3) 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.
