Installing the Drain Piping
(1)
Prepare a 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.
When doing this, leave a gap between the drain
socket of the unit and the PVC pipe to allow the
drainage to be checked. The transparent drain
pipe allows you to check drainage. (Fig. 3-88)
Tighten the hose clamps so
their locking nuts face
upward. (Fig. 3-88)
(2)
After connecting the drain piping securely, wrap
the supplied packing and drain pipe insulator
around the pipe, then secure it with the supplied
clamps. (Fig. 3-89)
Make sure the drain pipe has a downward gradient
(1/100 or more) and that there are no water traps.
