Indoor Unit Fixing; Drainage - Toshiba RAS-M18G3KVSG-TR Installation Manual

In case of right or left piping
• After scribing slits of the front panel
with a knife or a making-off pin, cut
them with a pair of nippers or an
equivalent tool.
In case of bottom right or bottom left piping
• After scribing slits of the front panel
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 connecting pipe within a radius of 30 mm.

core or the like for bending pipe.)
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 pipes to the 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 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 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 dewing results in a machine trouble, make sure to insulate both
connecting pipes. (Use polyethylene foam as insulating material.)
• When bending a pipe, carefully do it, not to crush it.
