Safety Precautions
The following safety precautions must be taken when using your air conditioner.
◆The unit should not be installed by the user. Ask the dealer or authorized
company to install the units except room air conditioners for the U.S.A and
Canada area.
◆If the unit is installed improperly, water leakage, electric shock or fire may
result.
◆Mount with the lowest moving parts at least 2.5 m above the floor or grade
level. (If applicable)
◆The manufacturer does not assume responsibility for accidents or injury
caused by an incorrectly installed air conditioner. If you are unsure about
installation, contact an installation specialist.
◆When installing the built-in type air conditioner, keep all electrical cables
such as the power cable and the connection cord in pipe, ducts, cable
channels e.t.c to protect them against liquids, outside impacts and so on.
◆This appliance is not accessible to the general public. This appliance
should be installed according to the provided installation instruction.
WARNING
INSTALLING THE UNIT
◆If the power cord of this air conditioner is damaged, it must be replaced by
the manufacturer, its service agent or similarly qualified persons in order to
avoid a hazard.
◆The unit must be plugged into an independent circuit if applicable or
connect the power cable to the auxiliary circuit breaker. An all pole
disconnection from the power supply must be incorporated in the fixed
wiring with a contact opening of >3mm.
◆Do not use an extension cord with this product.
◆If the unit is equipped with a power supply cord and a plug, the plug must
be accessible after installation.
◆The air conditioner must be installed in accordance with national wiring
regulations and safety regulations wherever applicable.

Indoor Unit
5mm
◆There must be no obstacles near the air inlet and outlet.
◆Install the indoor unit on a ceiling that can support its weight.
◆Maintain sufficient clearance around the indoor unit.
◆Make sure that the water dripping from the drain hose runs away correctly
and safely.
◆The indoor unit must be installed in this way, that they are out of public
access. (Not touchable by the users)
◆After connecting a chamber, insulate the connection part between the indoor
unit and the chamber with t10 or thicker insulation. Otherwise, there can be
air leak or dew from the connection part.
Space Requirements for Indoor Unit
You must have 5mm or more space between the ceiling and the bottom of indoor unit.
Otherwise, the noise from the vibration of indoor unit may bother the user.
When the ceiling is under construction, the hole for check-up must be made to
take service, clean and repair the unit.

2
Install the suspension bolts depending on the ceiling type.
3
Screw eight nuts to the suspension bolts making space for hanging the
indoor unit. Make sure you have space for hanging the indoor unit.
4
Hang the indoor unit to the suspension bolts between two nuts.

Purging the Unit
To prevent dirt or foreign objects from getting into the pipes during
installation, do NOT remove the pinch pipe completely until you
are ready to connect the piping.
NN
NNoo oott ttee ee
On delivery, the indoor unit is loaded with refrigerant gas.
All this gas must therefore be purged before connecting
the assembly piping.
To purge the inert gas, proceed as follows.
Unscrew the pinch pipe at the end of each refrigerant pipe.
Result: All inert gas escapes from the indoor unit.
EH035EAV_IM_E_25807 3/24/06 7:21 PM Page 9

Connecting the Refrigerant Pipe
There are two refrigerant pipes of different diameters:
◆
A smaller one for the liquid refrigerant
◆
A larger one for the gas refrigerant
◆
The inside of copper tube must be clean & has no dust.
The connection procedure for the refrigerant pipes varies according to
the exit position of the pipes from the indoor unit, as seen when facing
the indoor in the “A” side.
◆
Liquid refrigerant port
◆
Gas refrigerant port
◆

Remove the pinch pipe on the pipes and connect the assembly pipes to
each pipe, tightening the nuts, first manually and then with a torque
wrench, a spanner applying the following torque.
1
Must use insulator which is thick enough to cover the refrigerant tube to
protect the condensate water on the outside of pipe falling onto the floor
and the efficiency of the unit will be better.
2
Cut off any excess foam insulation.
3
Be sure that there must be no crack or wave on the bended area.
4
It would be necessary to double the insulation thickness(10mm or more)
to prevent condensation even on the insulator when if the installed area is
warm and humid.
5
If the pipes must be shortened refer to page 11.

If you wish to shorten the pipes, cut it with a pipe cutter, taking care to ensure
that the cut edge remains at a 90° angle with the side of the pipe. Refer to the
illustrations below for examples of edges cut correctly and incorrectly.
2
To prevent any gas from leaking out, remove all burrs at the cut edge of the
pipe, using a reamer.
3
Slide a flare nut on to the pipe and modify the flare.

Check that the flaring is correct, referring to the illustrations below for
examples of incorrect flaring.

Performing Leak Test & Insulation
To check for gas leaks on the indoor unit, check the connection part
of each refrigerant pipe by using a leak detector.
Once you have checked that there are no leaks in the system,
you can insulate the piping and hose.
To avoid condensation problems, place T13.0 or thicker Acrylonitrile
Butadien Rubber separately around each refrigerant pipe.
1
Wind insulating tape around the pipes.
2
Finish wrapping insulating tape around the rest of the pipes leading to the
outdoor unit.

When not installing the drain pump
Do not give the hose upward gradient after
the connection port.
This will cause water to flow backwards when
the unit is stopped, resulting in water leaks.
Do not apply force to the piping on the unit side
when connecting the drain hose. The hose should
not be allowed to hang loose from its connection to
the unit. Fasten the hose to a wall, frame or other
support as close to the unit as possible.

When installing a flexible hose, the difference of

be within 20mm. If the difference of each pivot is
more than 20mm, or a flexible hose is bent
