Deciding on where to install the indoor unit
Indoor Unit
◆Select a convenient location that permits the air to reach every corner of the
area to be cooled.
◆Pre-plan for easy and short routing of the refrigerant tubing and wiring to the
outdoor unit.
◆There should be no flammable gas, alkaline, substances present in the air.
◆Avoid location where obstacles preventing good air circulation are present.
◆Noise prevention should be considered in determining the unit's location.
◆The structure, where the unit is to be installed should be strong enough to
support the weight of the unit.
◆Do not install the unit where it will be exposed to direct sunlight.

1Select pipe directions.
When the directions are selected, drill 3-1/8'' (100mm, for pipe and cables)
and 1-3/4'' (40mm, for drain hose) diameter holes on the wall so that it
slants slightly downwards toward the outdoor for smooth water flow.
2Drill holes for anchor bolts according to the distance and mount them.
3Install the unit onto the ceiling. Be sure to arrange the drain hose so that it
is leveled lower than the drain hose connecting port of the indoor unit.
4If installing on dropped ceiling, install threaded rod onto anchor
bolt (expansion bolt) to long enough to suspend the unit right below the
dropped ceiling and the install the unit suspending on the threaded rod.
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.

Purging the unit
On delivery, the indoor unit is loaded with an inert nitrogen gas.
All this gas must therefore be purged before connecting the assembly
piping. To purge the inert gas, proceed as follows.
Unscrew the caps at the end of each pipe.
Result: All inert gas escapes from the indoor unit.
◆To prevent dirt or foreign objects from getting into the pipes
during installation, do NOT remove the caps completely until
you are ready to connect the piping.

Connecting the refrigerant pipe
E-11
ENGLISH
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 nuts 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.
5
◆
If the pipes must be shortened refer to page 12.

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 wrench, applying the following torque.

ENGLISH
Performing leak test & insulation
Before completing the installation (insulation of the hose and pipe),
you must check that there are no gas leaks.
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.
1
After closing both high and low stop valve of the outdoor unit, inject
nitrogen gas into refrigerant pipe to reach 28kgf/cm2.
1
Purge nitrogen gas after finishing leak test.
3
By using soap bubbles, check leak on flare nut connection of pipes.
2
Wind insulating tape around the pipes.
2
Finish wrapping insulating tape around the rest of the pipes leading to the
outdoor unit.

Drain hose installation
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
hole drilled in the wall, check that none of the following situations occur.
If draining pipe is not too long.
It may be extended the draining pipe by connecting as following figure.
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
directions.
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.

Connecting the connection cord
Wiring Diagram
The indoor unit is powered from the outdoor unit via the connection cord.
Remove the screw on the electrical component box and remove the cover
plate.
1
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.
3
Reassemble the electrical component box cover, carefully tightening the
screw.

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(SW01) and
RMC(SW02) 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(SW01) 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"

addresses should be same.
◆In case of installing the wired remote controller, all indoor units and the wired
remote controller must have the same RMC address.
◆Adjust K1 switch on the SW03 of the indoor unit connected to the wired
remote controller to "OFF" position.
