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 25-type (only) are large;
therefore, use the supplied insulation material.
(3) To mount the indoor unit on the rear panel.
1. When attaching the indoor unit, position the
IT
indoor unit onto the attachment tabs on the
upper part of the rear panel. (Fig. 3-26)
2. Press on the air outlet to hold it in place, and
press the lower part of the indoor unit until a
PT
"click" sound is heard and the indoor unit is
securely fastened to the attachment tabs on the
lower side of the rear panel. (Fig. 3-27)

Refer to Section 3-6. "Removing the Rear Panel
from the Unit" (Fig. 3-13).
Then lift up the indoor unit to remove.
3-11. Shaping the Tubing
Right-rear tubing
(1) Shape the refrigerant tubing so that it can easily
go through the hole. (Fig. 3-29)
(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 pressure 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 mounted on the rear panel.
