CAUTION

Indoor Unit Fixing

• For detaching the indoor unit from the

installation plate, pull the indoor unit
toward you while pushing its bottom up at
the speci

ed parts.

1. Pass the pipe through the hole in the wall and hook the indoor unit on the

installation plate at the upper hook.

2. Swing the indoor unit to right and left to con

rm that it is

rmly hooked up

on the installation plate.

3. While pressing the indoor unit onto the wall, hook it at the lower part on the

installation plate. Pull the indoor unit toward you to con

rm that it is

rmly

hooked up on the installation plate.

Drainage

1. Run the drain hose sloped downwards.

2. Put water in the drain pan and make sure that the water is drained out of

doors.

3. When connecting extension drain hose, insulate the connecting part of

extension drain hose with shield pipe.

NOTE

• The hole should be made at a slight downward slant on the outdoor side.

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

OUTDOOR UNIT

Installation Place

• A place which provides enough spaces around the outdoor unit as shown in

the diagram

• 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 20 m.
• There is no need to add refrigerant as long as the length of the connection

piping is 15 m or less.

• You will need to add 20g of refrigerant per meter of added connection piping

for installations requiring connection piping to be between 16 m to 20 m.

• An allowable height level is up to 10 m.
• A place where the drain water does not cause any problems

CAUTION

1. Install the outdoor unit in a location where there are no obstructions near

its air intake or air outlet.

2. When the outdoor unit is installed in a place that is always exposed to

strong winds like on the coast or on a high story of a building, secure the
normal fan operation using a duct or a wind shield.

3. Especially in windy areas, install the unit to prevent the 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 sul

de gas.

• A place where high-frequency

waves are likely to be generated,

such as from audio equipment,

welders, and medical equipment.

• Do not use the supplied drain nipple for draining water. Drain the water from

all the drain holes directly.

• To protect the outdoor unit from snow accumulation, install a holding frame,

and attach a snow protection hood and plate.

* Do not use a double-stacked design.

Precautions about Installation in Regions

with Snowfall and Cold Temperatures

• 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.

Indoor unit

Connecting cable

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.

The lower part of indoor unit may

oat,

due to the condition of piping and you
cannot

x it to the installation plate. In

that case, use the

screws provided to

x the unit and the installation plate.
