◆Combustible gases
◆Saline air
◆Machine oil
◆Sulphide gas
◆Special environmental conditions
If you must install the unit in such conditions, first consult your dealer.
Indoor Unit
◆There must be no obstacles near the air inlet and outlet.
◆Install the indoor unit on a surface that can support its weight.
◆Choose a position that enables the piping and cables to be easily connected to the outdoor unit and the
recommended length of 5 metres to be respected.
◆Leave enough clearance beneath the indoor unit to enable the filters to be removed without hindrance.
◆Maintain sufficient clearance around the indoor unit, as indicated in the diagram on the page opposite.
◆Make sure that the water dripping from the drain hose runs away correctly and safely.
◆You have just purchased a Free Joint Multi air conditioner and it has been installed by
your installation specialist.

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 9.

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.
Liquid
refrigerant
port
Gas refrigerant port

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 torque
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 13.

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 torque wrench, applying the following torque.

In case of welding the pipe, you must weld with nitrogen
gas blowing.

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.

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.

Care must be taken when installing the drainpipe and drain hose for
the indoor unit so that condensate water is drained correctly outside.
Fix the flexible hose to the drainpipe.
◆The connection port of the flexible hose and PVC drainpipe must be
fixed with PVC adhesives.
◆Check out that the connected part doesn’t leak.
1
Connect the flexible hose to the flexible hose port.
◆Make sure that a rubber ring is installed on the drain hose port.
2
Install the drainpipe as shortly as possible.
◆Give a slightly slant to the drainpipe for proper drainage of condensate
water.
◆There must be no gap on the connected part so that the drainpipe is
not separated from the flexible hose.

Assigning Address to Indoor Unit
Before installing the indoor unit, assign an address to the indoor unit
according to the air conditioning system plan.

The address of the indoor unit is assigned by adjusting MAIN(SW02).
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.
