<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.
Bend the connection pipe within a radius of 30 mm.
To connect the pipe after installation of the unit (figure)
400 mm
300 mm
R 30 mm (Use polisin (polyethylene)
core or the like for bending pipe.)
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 pipe to the auxiliary pipes
and wrap the facing tape around them.
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.
