3-5-2. 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 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 uneven surface 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. See diagram below.
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 generated.)
5) Apply approx. 2 g of adhesive on both sides of the drain hose without connection of the hard
PVC socket and the hard PVC pipe joint (VP20) in the field supply.
6) Connect the drain hose and the hard PVC pipe joint so that the adhesive area of both sides
can be overlapped.
Wipe off the protrusion-adhesive with a soft cloth.
Hard PVC pipe joint
(VP20 field supplied)
* Apply approx. 2 g of adhesive on both
sides of supplied the drain hose and the
hard PVC pipe joint (VP20) in the field
supply. Wipe off the protrusion-adhesive
with a soft cloth.
Note:
Be sure to tightly insert the hard PVC pipe joint
(including elbow) minimum 20 mm or more.
* However, do not use the hard PVC pipe joint
allowable more than 55 mm insertion.
* After checking the drainage, wrap the supplied packing and drain pipe insulator around the pipe.
