3-37. Installing the Drain Piping
(1) Prepare standard hard PVC pipe (O.D. 32 mm) for
the drain and use the supplied drain socket to pre-
vent water leaks. The PVC pipe must be pur-
chased separately.
When doing this, apply adhesive for the PVC pipe
at the connection point.
(2) If connecting a drain joint (supplied) to the thread-
ed drain port, first wrap the drain port threads with
sealing tape, then connect the joint. (Fig. 3-119a)
(3) After connecting the drain pipe securely, wrap
insulator (field supply) around the pipe.
(4) Ensure the drain pipe has a downward gradient
(1/100 or more) and prepare traps as indicated in
Fig. 3-119b.
(5) Also, in another part of the pipe arrangement, pre-
pare traps with an inspection plug to clean dust or
debris that may cause leaking of water.
(Fig. 3-120)
(6) After connecting the drain piping, slowly pour
water into the drain pan to check that the water
drains smoothly.
