4Cut off any excess foam insulation.
5If necessary, bend the pipe round, along the bottom of the indoor unit and
out through the appropriate hole, taking care to ensure that:
◆The piping does not jut out from the rear of the indoor unit
◆The bending radius is 100 mm or more
6
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.
There are two refrigerant pipes of different diameters:
◆A smaller one for the liquid refrigerant
◆A larger one for the gas refrigerant
A short length of piping is already fitted to the air conditioner. You
must extend this piping using assembly piping (optionally supplied).
The connection procedure for the refrigerant piping varies according
to the exit position of the piping from the indoor unit, as seen when
facing the air conditioner in position on the wall:
◆Right (A)
◆Left (B)

1With a knife, cut out the appropriate knock-out piece on the rear of the
indoor unit (unless you are connecting directly from the rear).
2Smooth the cut edges.

to each pipe, tightening the nuts, first manually and then with a wrench,
applying the following torque.

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
E-15
ENGLISH
To install the drain hose, proceed as follows.
1If necessary, connect the 2-metre extension to the drain hose.
2If you are using the extension, insulate the inside part of the extension
drain hose with a shield.
3Pass the drain hose under the refrigerant piping, taking care to keep the
drain hose tight.
4Pass the drain hose through the hole in the wall, making sure that it is
sloping downwards, as shown in the illustrations above.
Care must be taken when installing the drain hose for the indoor unit to ensure that any condensation
water is correctly drained outside. When passing the drain hose through the 65 mm hole drilled in the
wall, check that none of the following situations occur.
The hose must
NOT slope
upwards.
The end of the drain
hose must NOT be
placed in water.
Do NOT bend the
hose in different direc-
tions.
Keep a clearance of
at least 5 cm between
the end of the hose
and the ground.
Do NOT place the
end of the drain hose
in a hollow.

Route the connection cord through the side of the indoor unit and connect
the cable to terminals; refer to the figure below.
2
Route the other end of the cable to the outdoor unit through the ceiling &
the hole on the wall.

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"
