the installation plate at the upper hooks.
2. Swing the indoor unit to right and left to confirm that it is firmly hooked
up 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 up on the installation plate.

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.
Fig. 7-2-13
•
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 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 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.
NOTE
If the pipe is bent incorrectly, the indoor unit may unstably be set 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.

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 indoor unit may unstably be set on the wall. When bending
the connecting pipe, make sure to use a spring bender so as not to
crush the pipe.
Bend the connection pipe within a radius of 30 mm (Ø6.35) 40 mm
(Ø9.52).
