3-20. Installing the Drain Piping
(1) Prepare standard hard PVC pipe (O.D. 32 mm) for
the drain and use the supplied hose band to pre-
vent water leaks.
The PVC pipe must be purchased separately.
The transparent drain part on the unit allows you
to check drainage. (Fig. 3-63)
● Do not use adhesive at the
drain connection port on
the indoor unit.
● Insert the drain pipe until it
contacts the socket, as
shown in the figure at right,
then secure it tightly with
the hose band.
● Do not use the supplied
drain hose bent at a 90°
angle. (The maximum per-
missible bend is 45°.)
● Tighten the hose clamps so
their locking nuts face
upward. (FIg. 3-63)
(2) After connecting the drain piping securely, wrap
the supplied packing and drain pipe insulator
around the pipe, then secure it with the supplied
vinyl clamps. (Fig. 3-64)
Make sure the drain pipe has a downward gradient
(1/100 or more) and that there are no water traps.
