Installing The Drain Piping - Sanyo PNR-XS2432 Installation Instructions Manual

3-4. Installing the Drain Piping

(1) Prepare standard hard PVC pipe (O.D. 1-3/64 in.)
for the drain and use the supplied drain hose and
hose band to prevent water leaks.
The PVC pipe must be purchased separately.
The transparent part allows you to check drain-
age. (Fig. 3-6)
Tighten the hose clamps
CAUTION
so their locking nuts face
upward. (Fig. 3-6)
(2) After checking the drainage, wrap the supplied
packing and drain pipe insulator around the pipe.
(Fig. 3-7)
NOTE
Ensure the drain pipe has a downward gradient
(1/100 or more) and that there are no water traps.
CAUTION
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 10 in. Do not raise it any
higher than 10 in., as this could result
in water leaks.
(Fig. 3-9)
Do not install the pipe with an upward
gradient from the connection port. It
will cause the drain water to flow
backwards and leak when the unit is
stopped. (Fig. 3-10)
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 connec-
tion to the unit. Fasten the pipe to a
wall, frame, or other support as close
to the unit as possible. (Fig. 3-11)
Provide insulation for any drain pipes
that are installed indoors.
Do not install an air
bleeder tubes, as this
may cause water to spray
from the drain tube outlet.
