Left-hand connection with piping
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
9.52 mm
12.7 mm
Connect the pipe after installation of the
unit (figure)
270 mm
Gas side
230 mm
Liquid side
R30 or less (Dia. 6.35), R40 or less (Dia. 9.52), R50 or less (Dia. 12.7)
Make sure to use a spring bender to avoid crushing the pipe.

NOTE
If the pipe is incorrectly bent, the indoor unit may be
unstable 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.
Bending radius

40 mm
50 mm
(To the front flare)
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 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.
