3. How to install the indoor unit
3-1-5-2. Installing the Drain Pipe
CAUTION
Do not apply force to the drain port when connecting the
drain pipe. Install and fix it near the indoor unit as close
as possible.
Do not use adhesive when connecting the drain port pipe
and the drain hose.
(1) How to Install the Drain Pipe
1) First insert the supplied hose band into the drain port
pipe. Then make sure the head of the screw is facing
toward a technical engineer when placing the screw of
1
the hose band at an upward angle.
2) Insert the soft PVC socket of the supplied drain hose
to the drain port pipe. Do not use adhesive when
connecting the drain hose to the drain port pipe.
Insert it until the tip of the drain hose contacts the circular
2
projection rib of the drain port pipe.

3) Move the hose band so that the center position of the
hose band can be placed approx. 30 mm away from the
external plate of the indoor unit. (Fig. 2-28)
4) Screw the drain hose tightly facing the screw of the hose
band upward. (Torque: 2.5 N·m - 3.4 N·m) (If the screw
is tightened beneath the drain hose, the troubles will be
occurred.) Pay attention not to make hose band overlap
the circular projection rib and the sealed circulation
projection of the drain port pipe.
5) Apply approx. 2
hose without connection of the hard PVC socket and the
hard PVC joint (VP25) in the local supply.
6) Connect the drain hose and the hard PVC joint so that
the adhesive area of both sides can be overlapped.
Wipe off the protrusion-adhesive with a soft cloth.
