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

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.

Indoor Unit Installation
Ensure that the ceiling is strong enough to support
the weight of the indoor unit.
Before hanging the unit, test the strength of each attached
suspension bolt.

You must install the suspension bolts more than four
when installing the indoor unit.

Mark the place to insert the suspension bolt where you want to install the
indoor unit.
1
Insert bolt anchors. Use existing ceiling supports or construct a suitable
support as shown in figure.
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.
5
Screw the nuts to suspend the unit.
6
Adjust level of the unit by using measurement plate for all 4 sides.
7
Refer to pages 6~7 for the dimension.

For proper drainage of condensate, give a 3mm slant to the left or
right side of the unit which will be connected with the drain hose,
as shown in the figure. Make a tilt when you wish to install the
drain pump, too.
NN

Tubing must be laid and connected inside the ceiling when
suspending the unit. If the ceiling is already constructed, lay the
piping into position for connection to the unit before placing the
unit inside the ceiling.

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
◆
Drain hose 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.
