<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.

400 mm
Liquid side
300 mm Gas side
R 30 mm (Use polisin (polyethylene
core or the like for bending pipe.)
Use the handle of screwdriver, etc.
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 auxillary 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.
Auxiliary pipes
Installation plate
• 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.
