For Reference

If a heating operation would be continuously performed
for a long time under the condition that the outdoor
temperature is 0°C or lower, draining of defrosted water
may be difficult due to freezing of the bottom plate,
resulting in a trouble of the cabinet or fan.

It is recommended to procure an anti-freeze heater
locally for a safety installation of the air conditioner.

For details, contact the dealer.

Knockout procedure

• The indoor/outdoor connecting pipes can be con-

nected to 4 directions.

Take off the knockout part of the pipe cover in which
pipes or wires pass through the base plate.

• As shown in the figure, do not remove the pipe cover

from the cabinet so that the knockout hole can be
easily punched. To knock out, it is easily taken off by
hands by punching a position at the lower side of 3
connected parts with screwdriver along the guide
line.

• After marking the knockout hole, remove the burr and

mount the attached protective bush and guard
material for pass-through part in order to protect
pipes and wires.

After connecting the pipes, be sure to mount the pipe
cover. The pipe cover is easily mounted by cutting off
the slit at the lower part of the pipe cover.
