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.

Indoor Unit Fixing

• A place which can bear the weight of the outdoor unit and does not allow an
increase in noise level and vibration.
• A place where the operation noise and discharged air do not disturb your
neighbors.
• A place which is not exposed to a strong wind.
• A place free of a leakage of combustible gases.
• A place which does not block a passage.
• When the outdoor unit is to be installed in an elevated position, be sure to
secure its feet.
• An allowable length of the connecting pipe is up to 15 m.
• An allowable height level is up to 8 m.

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
