6-4. Installing the Drain Piping
(1) Prepare standard hard PVC pipe for the drain and
use the supplied drain hose and hose band to pre-
vent water leaks.
The PVC pipe must be purchased separately. The
transparent part allows you to check drainage.
(Fig. 1-17)
(2) After checking the drainage, wrap the supplied
packing and drain pipe insulator around the pipe.
(Fig. 1-18)
NOTE
Ensure the drain pipe has a downward gradient (1/100
or more) and that there are no water traps.
CAUTION
Tighten the hose clamps so
their locking nuts face upward.
(Fig. 1-17)
CAUTION
Do not install an air bleeder tube, as this may
cause water to spray from the drain tube outlet.
(Fig. 1-19)
If it is necessary to increase the height of the
drain pipe, the section directly after the connec-
tion port can be raised a maximum of 19-1/2".
Do not raise it any higher than 19-1/2", as this
could result in water leaks. (Fig. 1-20)
Do not install the pipe with an upward gradient
from the connection port. This will cause drain
water to flow backwards and leak when the unit is
stopped. (Fig. 1-21)
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. 1-22)
Provide insulation for any drain pipe that is run
indoors.
Refer to “ SUPPLEMENT ON DRAIN PIPING”.
