Indoor Unit Fixing; Drainage - Toshiba RAS-07 series Installation Manual

In case of 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.

R 30 mm (Use polisin (polyethylene)
core or the like for bending pipe.)
Use the handle of screwdriver, etc.
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.

CAUTION
Arrange the drain pipe for proper drainage from the unit.
Improper drainage can result in dew-dropping.
This air conditioner has the
structure designed to drain
water collected from dew, which
forms on the back of the indoor
unit, to the drain pan. Therefore,
do not store the power cord and
other parts at a height above
the drain guide.
