Preparation for Installation
When deciding on the location of the air conditioner with the owner,
the following restrictions must be taken into account.
General
Do NOT install the air conditioner in a location where it will come into
contact with the following elements:
◆Combustible gases
◆Saline air
◆Machine oil
◆Sulphide gas
◆Special environmental conditions
If you must install the unit in such conditions, first consult your dealer.

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)

Indoor Unit Installation
It is recommended to install the refnet joint before installing the indoor unit.

Suspension bolt(3/8" or M10)
Hole in anchor
Hole in plug
Insert
Ceiling support
1Place the pattern sheet on the ceiling at the spot where you want to
install the indoor unit.
2Insert bolt anchors, use existing ceiling supports or construct a suitable
support as shown in figure.
3Install the suspension bolts depending on the ceiling type.
4Screw eight nuts to the suspension bolts making space for hanging
the indoor unit.
5Check the level of the indoor unit by using a leveler or a vinyl tube filled
with water.
◆
A tilt of the indoor unit may cause malfunction of a built-in float switch and
water leaks.
6Adjust the height of the indoor unit by using the gauge of dimensions.
◆
The air inlet side should be slightly higher than the air outlet side
(approx. 5mm). The appropriate height from the ceiling surface is 25mm
for the air inlet and 20mm for the air outlet.
◆
You should adjust the gauge of dimensions and the pattern sheet to fit
the cutting dimensions of ceiling.
◆
Make sure that the indoor unit is installed at a level if the indoor unit
slants too much, there can be water leaks.
7Tighten the upper part nuts.
8Remove the gauge of dimensions after installing the indoor unit.
◆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
◆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; refer to page 6.

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.
Fix the electronic expansion valve kit with 2 screws(TH4x12) as shown at
the figure.
2
Connect the "OUT" pipe to the liquid refrigerant pipe.
3
Insulate the connection piping. A joint part of pipe needs double thickness
of insulation.
4
Connect the electronic expansion valve cable to the main PCB of indoor
unit.
5
The expansion valve has to be installed that the user has no access to it.

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 pipe must be clean & has no dust.
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 pipe 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 10.

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.

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.

Wind insulating tape around the pipes.

Finish wrapping insulating tape around the rest of the pipes leading to the

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.
Insert the flexible hose to the drain hose port.
1
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
2
Wrap the drain hose with the insulation drain as shown in figure and secure it.
3
◆Give a slightly slant to the drain hose for proper drainage of
condensate.
◆Secure the drain hose with an adhesive for PVC and tape
not to be separated from the unit.

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.

Assigning Address to Indoor Unit
Before installing the indoor unit, assign an address to the indoor unit
according to the air conditioning system plan.
1
The address of the indoor unit is assigned by adjusting MAIN(SW02) and
RMC(SW01) rotary switches.
2
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"
