3-24. Installing the Drain Piping
(1) Prepare a standard hard PVC pipe 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. 3-79)
Tighten the hose clamps so
their locking nuts face
upward. (Fig. 3-79)
(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. 3-80)
Make sure the drain pipe has a downward gradient
(1/100 or more) and that there are no water traps.
