(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. 3-123)
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. 3-124)
Raising the clamp to lift up the indoor unit will facilitate this work.
(Fig. 3-125)
To remove the indoor unit, press up on the 2 locations
(
▲ ▲ marks) on the lower part of the unit frame to disconnect the
installation tabs. Refer to Section 3-1. “Removing the Rear Panel
from the Unit” (Fig. 3-110).
Then lift up the indoor unit to remove it.
3-34. Shaping the Tubing
Right-rear tubing
(1) Shape the refrigerant tubing so that it can easily go into the hole.
(Fig. 3-126)
(2) After performing a leak test, wrap both the refrigerant 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.
Left or left-rear tubing
(1) Pass the tubing and drain hose into the rear of the indoor unit.
Provide sufficient length for the connections to be made.
Next, bend the tubing with a pipe bender, and connect them.
(2) After performing a leak test, wrap the refrigerant tubing and drain
hose together with insulating tape, as shown in the figure at right.
(Fig. 3-128)
Then fit the tubing into the tubing storage space in the rear of the
indoor unit and clamp in place.
(3) Adjust the indoor unit so that it is securely installed onto the rear
panel.
3-35. Installing the Drain Hose
a) The drain hose should be slanted downward to the
outside. (Fig. 3-129)
b) Never form a trap in the course of the hose.
c) If the drain hose will run in the room, insulate the hose* so that
chilled condensation will not damage furniture or floors.
* Foamed polyethylene or its equivalent is recommended.
