Piping on the bottom right or the bottom left
1) 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
1) 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.
Connecting the pipe after installation of the
unit (figure)
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.
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.
9-3-6. Indoor Unit Installation
1) Pass the pipe through the hole in the wall, and
hook the indoor unit on the installation plate at
the upper hooks.
2) Swing the indoor unit to right and left to confirm
that it is firmly hooked on the installation plate.
3) While pressing the indoor unit onto the wall,
hook it at the lower part on the installation plate.
Pull the indoor unit toward you to confirm that it
is firmly hooked on the installation plate.4. Pull
the connecting cable through the cable slot on
the rear panel so that it protrudes about 15 cm
out of the front.
