3-15. Duct for Fresh Air
There is a duct connection port (knock-out hole) at
the right-rear of the top panel of the indoor unit for
drawing in fresh air. If it is necessary to draw in fresh
air, remove the cover by opening the hole and con-
necting the duct to the indoor unit through the con-
nection port. (Fig. 3-50)
3-16. Shaping the Tubing
●
The positions of the refrigerant tubing connections
are shown in the figure below. (The tubing can be
routed in 3 directions.)
* When routing the tubing out through the top or right
sides, knock out the appropriate parts in the top
panel and cut notches in the side panel as shown
in Fig. 3-35.
* When routing the tubing out through the top, the
optional L-shape tubing kit is required.
3-17. Installing the Drain Piping
●
Prepare standard PVC pipe for the drain and con-
nect it to the indoor unit drain pipe with the sup-
plied hose clamps to prevent water leaks.
(1) Drain hose connection
●
The drain hose is connected below the refrigerant
tubing.
(2) Installing the drain hose
●
To install the drain hose, first place 1 of the 2 hose
bands over the unit drain port and the other hose
band over the hard PVC pipe (not supplied). Then
connect both ends of the supplied drain hose.
●
On the unit drain side, grasp the hose band with
pliers and insert the drain hose all the way to the
base.

CAUTION
●
Attach so that the hose
band fastener is on the side
of the drain port. (Fig. 3-54)
●
Attach the hose bands so
that each is approximately
5 to 25 mm from the end of
the supplied drain hose.
If the tubing is to be routed out together, use a
box cutter or similar tool to cut out the part of
the rear cover indicated by the marked area in
the figure below, to match the positions of the
tubes. Then draw out the tubing.
