Left-hand connection with piping
Bend the connecting pipes so that they are posi-
tioned 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.
Fig. 10-3-17
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.
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.
