ENGLISH
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.
5mm or more
◆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.

◆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.
IMPORTANT
You must install the suspension bolts more than four
when installing the indoor unit.
IMPORTANT
Place the pattern sheet on the ceiling at the spot 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.
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.

ENGLISH
◆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

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.

Connecting the Refrigerant Pipe
There are two refrigerant pipes of differing 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 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.

If the pipes must be shortened refer to page 11.

Make sure that you have the required tools available (pipe cutter, reamer,
flaring tool and pipe holder).
1
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.
4
Check that the flaring is correct, referring to the illustrations below for
examples of incorrect flaring.

Align the pipes and tighten the flare nuts first manually and then with
a wrench, applying the following torque.

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.

Drain Hose Installation

ENGLISH
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 or left side of the base pan.
Remove the rubber cap of the drain hose port.

When not installing the drain pump
Do not give the hose and 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.

Internal diameter of the drain hose should be the same or slightly bigger
than the external diameter of the drain hose port.

If external static pressure is too great(due to long extension of ducts, for
example), the air flow volume may drop too low at each air outlet. This problem
can be solved by increasing the fan speed using the following procedure.

Assigning Address to Indoor Unit
E-18
Before installing the indoor unit, assign an address to the indoor unit
according to the air conditioning system plan.
1
The MAIN address is for communication between the indoor unit and the outdoor
unit. Therefore, you must set it to operate the air conditioner properly.
3
It is required to set the RMC address if you install the wired remote controller
and/or the centralized controller.
4
If you install optional accessories such as the wired remote controller, centralized
controller, etc. see an appropriate installation manual.
5
If an optional accessory is not installed, you do not have to set the RMC
address. However, adjust K1 and K2 switches of the SW03 DIP switch to "ON"
position in this case.
6
Set the MAIN address by adjusting the rotary switch(SW02) from 0 to F. Each
indoor unit connected to the same outdoor unit must have different address.
i. e. If an indoor unit does not have an optional accessory and its MAIN address
is "4"
