Duct For Fresh Air; Installing The Drain Piping - Sanyo C2432A Installation Instructions Manual

3-11. Duct for Fresh Air

There is a duct connection port (knock-out hole) at the
right-rear on the Panel Top of the indoor unit for
drawing in fresh air. If it is necessary to draw in fresh
air, remove the cover by knocking out and connect the
duct to the indoor unit through the connection port.
(Fig. 3-32)
If connection at the right-rear on the Panel Top is not
appropriate, another duct connection port can be made
by cutting an opening on the left side of the Rear Panel
of the indoor unit as shown in Fig. 3-33.

3-12. Installing the Drain Piping

Prepare a standard PVC pipe (O.D. 1-3/64 in.) for
the drain and connect it to the indoor unit drain pipe
with the supplied hose clamps to prevent water
leaks.
Connect the drain piping so that it slopes downward
from the unit to the outside. (Fig. 3-34)
Never allow traps to occur in the course of the
piping.
Insulate any piping inside the room to prevent
dripping.
Use the supplied drain pipe to connect the drain
pipe with the drain outlet of the indoor unit.
After connecting the drain pipe securely, wrap the
supplied drain pipe insulator around the pipe, seal
the gap at the drain socket with the supplied black
insulation tape, then secure it with clamps.
(Fig. 3-35)
After the drain piping, pour water into the drain pan
to check that the water drains smoothly.
Check local electrical codes
CAUTION
and regulations before
obtaining wire. Also, check
any specified instruction or
limitations.
