<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 connecting pipe within a radius of 30 mm.

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, carefully do it, not to
crush it.
