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.

Indoor Unit Installation
It is recommended to install the refnet joint before installing the indoor unit.
Concrete
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.
◆
Atilt 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.
◆
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 pages 6 and 7.

during installation, do NOT remove the pinch pipe completely
until you are ready to connect the piping.

On delivery, the indoor unit is loaded with inert 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.
2
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.
3
Be sure that there must be no crack or wave on the bended area.
4
Before connecting the reprigerant pipe, open the cover side.
1
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.

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.

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
Butadiene 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.

Install air ventilation to drain condensate water
smoothly.
Check that the indoor unit is level with the ceiling by using the leveler.

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.

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.

Assigning Address to Indoor Unit
E-16
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 "0"
