Indoor Unit Fixing; Drainage; Outdoor Unit; Installation Place - Toshiba RAS-137SKV Series Installation Manual

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.
Auxiliary pipes
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 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.
CAUTION
1. Install the outdoor unit without anything blocking the air discharging.
2. When the outdoor unit is installed in a place always exposed to strong
wind like a coast or on a high storey of a building, secure the normal fan
operation using a duct or a windshield.
3. In particularly windy areas, install the unit such as to avoid admission of
wind.
4. Installation in the following places may result in trouble.
Do not install the unit in such places.
• A place full of machine oil
• A saline-place such as the coast
• A place full of sulfi de gas
• A place where high-frequency
waves are likely to be generated
as from audio equipment, welders,
and medical equipment
Do not form the
drain hose into
a wavy shape.
Do not put the
