Installing the Drain Pipe
(1) Prepare standard hard PVC pipe (O.D. 32 mm) for the
drain and use the supplied hose band to prevent water
leaks.
The PVC pipe must be purchased separately.
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°.)

packing and drain pipe insulator around the pipe, then
secure it with the vinyl clamps . (Fig. 6-9)

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.
(Fig. 6-12)

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. (Fig. 6-13)
