Make sure the drain pipe has a downward slant (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. (Fig. 1-41)
Prohibited
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 1.64 ft. (500 mm). Do
not raise it any higher than 1.64 ft. (500 mm), as
this could result in water leaks. (Fig. 1-42)

Do not install the pipe with an upward slant from the
connection port. This will cause the drain water to flow
backward and leak when the unit is not operating.
(Fig. 1-43)
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. (Fig. 1-44)
