3-24. Installing the Drain Piping
(1) Prepare 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. 3-98)
(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. 3-99)
Make sure the drain pipe has a downward gradient
(1/100 or more) and that there are no water traps.
