Installing the Drain Pipe
(1) Prepare standard hard PVC pipe (O.D.26 mm) for the
drain and use the supplied hose band to prevent water
leaks.
The PVC pipe must be purchased separately.
The transparent drain part on the unit allows you to
check drainage.
CAUTION
Do not use adhesive tape at the drain connection
port on the indoor unit.
Insert the drain pipe until it contacts the socket, and
then secure it tightly with the hose band.
Do not use the supplied drain hose bent at a 90°
angle. (The maximum permissible bend is 45°.)
Tighten the hose clamps so their locking nuts face
upward.
Horizontal Installation
NOTE
Make sure the drain pipe has a downward gradient
(1/100 or more) and that there are no water traps.
CAUTION
Do not install an air bleeder as this may cause
water to spray from the drain pipe outlet.
Prohibited
Air bleeder
If it is necessary to increase the height of the drain
pipe, the section directly after the connection port
can be raised a maximum of 500 mm. Do not raise
it any higher than 500 mm, as this could result in
water leaks.
300 mm or less
500 mm or less
Good
Do not install the pipe with an upward gradient from
the connection port.
This will cause the drain water to flow backward and
leak when the unit is not operating.
Upward gradient
Prohibited
Do not apply force to the piping on the unit side
when connecting the drain pipe.
The pipe should not be allowed to hang unsupported
from its connection to the unit.
Fasten the pipe to a wall, frame, or other support as
close to the unit as possible.
Support pieces
(2) Installing the drain hose
First insert the drain hose (supplied) to the hose band
(supplied) and then install the drain hose to the unit
drain port.
Insert until the drain hose bumps to the end.
Hose band screw torque is 30 - 35 N · cm.
Connect both the drain hose and PVC pipe
(VP20 or similar material, not supplied).
Insert until the PVC pipe bumps to the end and adhere
with PVC adhesive.
