In case of right or left piping
• After making slits on the front panel with a knife or similar tool, cut
them out with a pair of nippers or an equivalent tool.
In case of bottom right or bottom left piping
• After making slits on the front panel with a knife or similar tool, cut
them out with a pair of nippers or an equivalent tool.
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.
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.

6.35 mm 30 mm
9.52 mm 40 mm
12.7 mm 50 mm
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.
