If the tubing is to be routed out
together, use a box cutter or simi-
lar 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.

3-28. Installing the Drain Piping
Prepare standard PVC pipe for the drain and connect it to the
indoor unit drain pipe with the supplied 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.
If other commercially available hose bands are used, the drain
hose may become pinched or wrinkled and there is danger of
water leakage. Therefore be sure to use the supplied hose bands.
When sliding the hose bands, be careful to avoid scratching the
drain hose.
Do not use adhesive when connecting the supplied drain hose to
the drain port (either on the main unit or the PVC pipe).
Wrap the hose with the supplied drain hose insulation and use the
4 twist ties so that the hose is insulated with no gaps.
Connect the drain piping so that it slopes downward from the unit
to the outside. (Fig. 3-107)
3-26. 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 connecting the duct to the indoor unit
through the connection port. (Fig. 3-104)
3-27. 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. 3-89.
* When routing the tubing out through the top, the optional
L-shape tubing kit is required.
