Safety Precautions
The following safety precautions must be taken when using your air conditioner.
WARNING
 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.
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.

Deciding on where to install the indoor unit
Indoor unit
 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
5mm
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
1
Place the pattern sheet on the ceiling at the spot where you want to install
the indoor unit.
Note Since the diagram is made of paper, it may shrink or stretch
slightly due to temperature or humidity. For this reason,
before drilling the holes maintain the correct dimensions
between the markings.
2
Insert bolt anchors. Use existing ceiling supports or construct a suitable
support as shown in figure.
3
Install the suspension bolts depending on the ceiling type.
CAUTION  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.
 If the length of suspension bolt is more than 1.5m,
it is required to prevent vibration.
4
Screw eight nuts to the suspension bolts making space for hanging the
indoor unit.
CAUTION You must install the suspension bolts more than four
when installing the indoor unit.
5
Hang the indoor unit to the suspension bolts between two nuts.
Note You must install the suspension bolts more than four when
installing the indoor unit.
6
Screw the nuts to suspend the unit.
7
Adjust level of the unit by using measurement plate for all 4 sides.
Note 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.
It is recommended to install the refnet joint before installing the indoor unit.

ENGLISH
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.
Note 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.
Purging the unit
 The designs and shape are subject to
change according to the model.

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 thickness of tube should not be less than 1.0mm.
 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.

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

Note If the pipes must be shortened refer to page 11.
2
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.
3
Cut off any excess foam insulation.
4
Be sure that there must be no crack or wave on the bended area.
5
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.

Cutting/Flaring the pipes
1
Make sure that you have the required tools available (pipe cutter, reamer,
flaring tool and pipe holder).
2If 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.
3
To prevent any gas from leaking out, remove all burrs at the cut edge of the
pipe, using a reamer.
4
Slide a flare nut on to the pipe and modify the flare.

Performing leak test & insulation
Insulation
Once you have checked that there are no leaks in the system,
you can insulate the piping and hose.
1
To avoid condensation problems, place T13.0 or thicker Acrylonitrile
Butadien Rubber separately around each refrigerant pipe.
Note Always make the seam of pipes face upwards.
2
Wind insulating tape around the pipes.
3
Finish wrapping insulating tape around the rest of the pipes leading to the
outdoor unit.

Drain hose installation
Care must be taken when installing the drain hose for the indoor unit to
ensure that any condensate water is correctly drained outside.
The drain hose can be installed to the right of the base pan.
1
Unscrew the 4 tapped screws to remove the cover of the drain hose
connection port.
2
Insert the flexible hose to the drain hose port.
Note Fix the flexible hose to the indoor unit with the supplied cable
clamp securely.
(Use the screwdriver to fix the flexible hose securely.)
3
Install the drain hose so that its length can be as short as possible.
Internal diameter of the drain hose should be the same or slightly bigger
than the external diameter of the drain hose port.
Inner diameter of the drain hose
Note Give a slightly slant to the drain hose for proper drainage of
condensate.
Fix the flexible hose to the PVC with the supplied cable tie
securely.

CAUTION
Do not apply force to the piping on the unit side when

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 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.
When installing the drain pump
The maximum height of drain pump hose is 75cm or less.
If it is raised higher than 75cm, there can be water leaks.

Assigning address to indoor unit
1
Before installing the indoor unit, assign an address to the indoor unit
according to the air conditioning system plan.
2
The address of the indoor unit is assigned by adjusting MAIN(SW02) and
RMC(SW04) rotary switches.
3
It is required to set the RMC address if you install the wired remote control
and/or the centralized control.
4If you install optional accessories such as the wired remote control, centralized
control, etc. see an appropriate installation manual.
5If an optional accessory is not installed, you do not have to set the RMC address.
However, adjust K1 and K2 switches of the SW05 DIP switch to "ON" position in
this case.
