<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 in-
door unit may unstably be set on the wall. When bend-
ing the connecting pipe, make sure to use spring
bender so as not to crush the pipe.
Bend the connection pipe within a radius of 30 mm.

NOTE :
If the pipe is bent incorrectly, the indoor unit may un-
stably be set on the wall.
After passing the connecting pipe through the pipe
hole, connect the connecting pipe to 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 left-
ward piping and rear-leftward piping, bind the
auxiliary pipes (two) only with facing tape.
• 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 con-
necting pipes to each other and cut off the in-
sulating 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 the connecting
pipes. (Use polyethylene foam as insulating
material.)
• When bending a pipe, carefully do it not to crush
it.
