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 circular 
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. 3-95)
 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.) Pay attention not to make hose band overlap 
the circular projection rib and the sealed ciculation 
projection of the drain port pipe.
 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 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.
Drain port
Do not use adhesive here.
*   Drain port may possibly be damaged if 
PVC adhesive is used.
*   After checking the drainage, wrap the supplied packing and drain pipe insulator around the pipe.
Do not make hose band overlap the circular projection 
rib and the sealed ciculation projection of the drain 
port pipe. (Torque: 2.5 N·m - 3.4 N·m)
Note:
Be sure to tightly insert the hard PVC 
pipe joint (including elbow) minimum 
20 mm or more.

supply. Wipe off the protrusion-adhesive with a soft 
cloth.
