Piping and drain hose forming
Since condensation results in machine trouble,
make sure to insulate both the connecting pipes
separately.
(Use polyethylene foam as insulating material.)

Relocating drain hose
For left connection, left-bottom connection and
rear-left connection’s piping, it is necessary to
relocate the drain hose and drain cap.
1) Cutting front panel slit.
Cut out the slit on the left or right side of the front
panel for the left or right connection and the slit
on the bottom left or right side of the front panel
for the bottom left or right connection with a pair
of nippers.
2) Remove the drain cap
Clamp drain cap with needle-nose pliers, and
pull out.

Fig. 10-3-14
6) Attach the drain hose
Insert the drain hose firmly until the connector
contacts with the insulation, then secure it in
place using the original screw.
Always use the original screw that secured
the drain hose to the unit.
If using a different screw may cause water to
leak.
CAUTION
Securely insert the drain hose and drain cap;
otherwise, water may leak.
NOTE
The packaged foam polystyrene can
be used to make replacement of the
drain cap and drain hose easier.
Piping on the right side or the left side
• After making slits on the front panel with a knife or
similar tool, cut them out with a pair of nippers or
an equivalent tool.
