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.
5Hang the indoor unit to the suspension bolts between two nuts.
6Screw the nuts to suspend the unit. Cut a pad stopper and place it on the
bracket at this time.
7
Adjust the unit to the appropriate position considering the installation area for the front
panel.
7-1 Place the pattern sheet on the indoor unit.
7-2 Adjust a space between the ceiling and the indoor unit by using the gauge
of dimensions.
7-3 Fix the indoor unit securely after adjusting level of the unit by using a leveler.
7-4 Remove the pattern sheet, connect the other cables and install the front panel.
◆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
◆Piping 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.

◆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
E-10
There are two refrigerant pipes of differing diameters:
◆
Asmaller one for the liquid refrigerant
◆
Alarger 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 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.
5
Align the pipes and tighten the flare nuts first manually and then with
a torque wrench, applying the following torque.

Performing Leak Test & Insulation
E-12
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 around each refrigerant pipe.
1
Wind insulating tape around the pipes and drain hose.
2
Finish wrapping insulating tape around the rest of the pipes leading to the
outdoor 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.

If it is necessary to increase the height of the drainpipe,
install the drainpipe straightly within 300 mm from the
flexible hose port. If it is raised higher than 550 mm,
there can be water leaks.
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

outdoor unit. Therefore, you must set it to operate the air conditioner
properly.
◆ You can set the MAIN address from ‘00’ to ‘39’ by mixing SW01 and
SW02. The MAIN address from ‘00’ to ‘39’ should differ from each other.
◆ Check the indoor unit address on the plan that you are to install and set
the address according to the plan.
Setting RMC Address
◆ The SW03 RMC switch is the address setting switch for controlling the
indoor unit with the wired remote controller and centralized controller.
◆ You must set the SW03, K1 and K2 switch when using the wired remote
controller and centralized controller.
◆ You don’t have to set the SW03 RMC switch when not using the wired
remote controller and centralized controller.
