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 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.
<In case of bottom right or bottom left piping>
•
After scribing slits of the back body with a knife or
a making-off pin, cut them with a pair of nippers or
an equivalent tool.

<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.

WARNING
•
Do not perform flare connection inside a building
or dwelling or room, when joining the heat
exchanger of indoor unit with interconnection
piping. Refrigerant connection inside a building
or dwelling or room must be made by brazing or
welding. Joint connection of indoor unit by flaring
method can only be made at outdoor or at
outside of building or dwelling or room. Flare
connection may cause gas leak and flammable
atmosphere.
