Bend the connecting pipes so that they are
positioned within 43 mm above the wall surface.
If the connecting pipes are positioned more than
43 mm above the wall surface, the indoor unit
may be unstable.
When bending the connecting pipe, make sure
to use a spring bender to avoid crushing the pipe.
Refer to the table below for the bending
radius of each connection pipe.
Outer diameter
6.35 mm

• Carefully arrange the pipes so that none of the
pipes 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 condensation can result in machine
performance trouble, be sure to insulate both
connecting pipes.
(Use polyethylene foam as insulating material.)
• When bending a pipe, be careful not to crush it.
