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 spring bender so as not to
crush the pipe.
Bend the connection pipe within a radius of
30 mm.

unstably be set on the wall.
After passing the connecting pipe through the
pipe hole, connect the connecting pipe to the
auxiliary pipes and wrap around them wirh the
facing tape.
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 each other 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 the connecting
pipes.
(Use polyethylene foam as insulating
material.)
• When bending a pipe, carefully do it not to
crush it.
