Installing The Drain Piping - Sanyo SPW-X483GH56 Installation Instruction

3-12.

Installing the Drain Piping

(1) Prepare a standard hard PVC pipe (O.D. 32 mm)
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 drain part allows you to check
drainage. (Fig 3-38)

(2) After checking the drainage, wrap the supplied
packing and drain pipe insulator around the pipe.

NOTE
Make sure 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 25 cm. Do not raise it
any higher than 25 cm, as this could
result in water leaks. (Fig. 3-41)
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. 3-42)
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. 3-43)
Provide insulation for any pipes that
are installed indoors.
Tighten the hose clamps so
their locking nuts face
upward. (Fig 3-38)
Do not install an air
bleeder as this may cause
water to spray from the
drain pipe outlet.
