<Left-hand connection with piping>
Bend the connecting pipe so that it is laid within
43 mm above the wall surface.
If the connecting pipe is laid exceeding 43 mm
above the wall surface, the indoor unit may
unstably be set on the wall.
When bending the connecting pipe, make sure to
use a spring bender so as not to crush the pipe.
Refer to the table below for the bending
radius of each connection pipe.
Fig. 10-3-19
NOTE :
If the pipe is bent incorrectly, the indoor unit may
unstably be set on the wall.
After passing the connecting pipe through the pipe
hole, connect the connecting pipes to the auxiliary
pipes and wrap the facing tape around them.

• After scribing slits of the front panel with a knife
or a making-off pin, cut them with a pair of
nippers or an equivalent tool.

CAUTION
• Bind the auxiliary pipes (two) and connecting
cable with facing tape tightly.
In case of leftward piping and rear-leftward
piping, bind the auxiliary pipes (two) only with
facing tape.

• Carefully arrange pipes so that any pipe does not
stick out of the rear plate of the indoor unit.
• Carefully connect the auxiliary pipes and
connecting pipes to one another and cut off the
insulating tape wound on the connecting pipe
to avoid double-taping at the joint, moreover,
seal the joint with the vinyl tape, etc.
• Since dewing results in a machine trouble,
make sure to insulate both connecting
pipes. (Use polyethylene foam as insulating
material.)
• When bending a pipe, be careful not to crush it.
