SMMS High-Wall Type
▼ In case of bottom right or bottom left piping
• After scribing slits of the front panel with a knife or a marking-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 43mm above the wall surface. If the connecting pipe is laid
exceeding 43mm 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.
To connect the pipe after installation of the unit (figure)
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.
• Bind the auxiliary pipes (two) and power supply wiring and control wiring with facing tape tightly. In case
of leftward piping and rear leftward piping, bind the auxiliary pipes (two) only with facing tape.
Installation plate
• 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 one another 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 dew 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.
