electric shocks or fire.
■
Perform installation work in accordance with this
installation manual.
Improper installation may lead to water leakage,
electric shocks or fire.
■
When a unit is installed in a small room, it is
necessary to take measures so that the leaked
refrigerant amount does not exceed the limit even if it
leaks. As for the measures to prevent the leak from
not exceeding the limit, please consult with your
distributor.
If the leaked amount exceeds the limit, it may cause
an oxygen deficiency accident.
Be sure to use only the specified accessories and
parts for installation work.
Failure to use the specified parts may result in water
leakage, electric shocks, fire, or the unit falling.
Install the air conditioner on a foundation that can
withstand its weight.
Insufficient strength may result in the fall of equipment
and causing injury.
■ Carry out the specified installation work in consideration
of strong winds, typhoons, or earthquakes.
Improper installation work may result in accidents due
to fall of equipment.
Make certain that all electrical work is carried out by
qualified personnel according to the local laws and
regulations and this installation manual, using a
separate circuit.
Insufficient capacity of the power supply circuit or
improper electrical construction may lead to electric
shocks or fire.
Make sure that all wiring is secure, using the specified
wires and ensuring that external forces do not act on
the terminal connections or wires.
Incomplete connection or fixing may cause a fire.
When wiring between the indoor and outdoor units,
and wiring the power supply, form the wires so that the
frontside panel can be securely fastened.
If the frontside panel is not in place, overheat of the
terminals, electric shocks or a fire may be caused.
If refrigerant gas leaks during installation work,
ventilate the area immediately.
To xic gas may be produced if refrigerant gas comes
into contact with fire.
After completing the installation work, check to make
sure that there is no leakage of refrigerant gas.
To xic gas may be produced if refrigerant gas leaks
into the room and comes into contact with a source of
fire, such as a fan heater, stove or cooker.

Precautions for R-407C
The refrigerant requires strict cautions for keeping the system
clean, dry and tight.
- Clean and dry
Foreign materials (including mineral oils or moisture) should be
prevented from getting mixed into the system.
- Tight
Read "Precautions on refrigerant piping" on page 5 carefully and
follow these procedures correctly.
Since R-407C is a mixed refrigerant, the required additional
refrigerant must be charged in its liquid state. (If the refrigerant is
in state of gas, its composition changes and the system will not
work properly).
The connected indoor units must be indoor units designed
exclusively for R-407C.
Installation
For installation of the indoor unit(s), refer to the indoor unit
installation manual.
Illustrations show class 125 outdoor unit type. Other types also
follow this installation manual.
This outdoor unit requires the pipe branching kit (optional) when
used as the outdoor unit for the simultaneous operation system.
Refer to catalogues for details.
Never operate the unit without the thermistor (R3T), burning of
the compressor may result.
Be sure to confirm the model name and the serial no. of the
outer (front) plates when attaching/detaching the plates to avoid
mistakes.
When closing the service panels, take care that the tightening
torque does not exceed 4.1 Nm.
Handling
As shown in the figure, bring the unit slowly by grabbing the left and
right grips.
Place your hands on the corner instead of holding the suction inlet in
the side of the casing, otherwise the casing could be deformed.
Ta ke care not to let hands or objects come in contact with
rear fins.
S
ELECTING
Select an installation site where the following conditions are
satisfied and that meets with your customer's approval.
- Places which are well-ventilated.
- Places where the unit does not bother next-door neighbours.
- Safe places which can withstand the unit's weight and
- Places where there is no possibility of flammable gas or
- Places where servicing space can be well ensured.
- Places where the indoor and outdoor units' piping and wiring

When installing the unit in a place exposed to strong wind, pay
special attention to the following.
Strong winds of 5 m/sec or more blowing against the outdoor
unit's air outlet causes short circuit (suction of discharge air),
and this may have the following consequences:
- Deterioration of the operational capacity.
-Frequent frost acceleration in heating operation.
- Disruption of operation due to rise of high pressure.
- When a strong wind blows continuously on the face of the
unit, the fan can start rotating very fast until it breaks.
Refer to the figures for installation of this unit in a place where
the wind direction can be foreseen.
Tu rn the air outlet side toward the building's wall, fence or
screen.
Make sure there is enough room to do the installation
PRECAUTIONS ON INSTALLATION
■ Check the strength and level of the installation ground so that
the unit will not cause any operating vibration or noise after
installation.
■ In accordance with the foundation drawing in the figure, fix the
unit securely by means of the foundation bolts. (Prepare four
sets of M12 foundation bolts, nuts and washers each which are
available on the market.)

REFRIGERANT PIPE SIZE AND ALLOWABLE PIPE
LENGTH
All field piping must be installed by a licensed refrigeration
technician and must comply with relevant local and
national regulations.
To persons in charge of piping work:
■ Be sure to open the shut-off valve after piping
installing and vacuming is complete. (Running the
system with the valve closed may break the
compressor.)
■ It is forbidden to discharge refrigerant into the
atmosphere. Collect the refrigerant in accordance with
the freon collection and destruction law.
■ Do not use flux when brazing the refrigerant piping.
For brazing, use phosphor copper brazing filler metal
(BCuP) which does not require a flux.
(If a chlorine flux is used, the piping will corrode, and if
the flux contains fluoride, it will cause the coolant oil to
deteriorate, adversely affecting the coolant piping
system.

- Install the branch pipes horizontally. (Maximum inclination:
20° or less)
- Length of branch pipe to the indoor unit should be as short as
possible.
-Try to keep lengths of both branch pipes to the indoor unit
equal.
■ When using existing refrigerant piping
Pay attention to the following points when using existing
refrigerant piping
■ In the following situations, the existing piping should not be
re-used and new piping should be installed.
- If the previously used model had problems with its
compressor (this might cause oxidized coolant oil, scale
residue and other adverse effects).
- If the indoor or outdoor units were disconnected from the
piping for a long period of time (water or dirt might have
gotten into the piping).
- If copper piping is corroded.
■ Flares should not be re-used but rather new ones made in
order to prevent leaks.
■ Check welded connections for gas leaks, if the local piping
has welded connections.
■ Replace deteriorated insulation with new material.
PRECAUTIONS ON REFRIGERANT PIPING
■ Do not allow anything other than the designated refrigerant to
get mixed into the freezing cycle, such as air, etc. If any
refrigerant gas leaks while working on the unit, ventilate the
room thoroughly right away.
■ Use R-407C only when adding refrigerant
Installation tools:
Make sure to use installation tools (gauge manifold charge hose,
etc.) that are exclusively used for R-407C installations to
withstand the pressure and to prevent foreign materials (e.g.
mineral oils and moisture) from mixing into the system.
Vacuum pump:
Use a 2-stage vacuum pump with a non-return valve
Make sure the pump oil does not flow oppositely into the system
while the pump is not working.
Use a vacuum pump which can evacuate to –100.7 kPa (5 Torr,
–755 mmHg).
■ In order to prevent dirt, liquid or dust from entering the piping,
cure the piping with a pinch or taping.
Place Installation period Protection method

■ Since the side boards may be deformed if only a torque wrench
is used when loosening or tightening flare nuts, always lock the
shut-off valve with a wrench and then use a torque wrench.
Do not place wrenches on the valve lid.
■ For cooling operation under low ambient temperature or any
other operation under low pressure, apply silicon sealing pad,
etc. to prevent the freezing of flare nut gas pipe portion of the
stop valve. Refer to the figure.

Precautions when connecting field piping and regarding
insulation
■ Be careful not to let the indoor and outdoor branch piping come
into contact with the compressor terminal cover.
If the liquid-side piping insulation might come into contact with it,
adjust the height as shown in the figure below. Also, make sure
the field piping does not touch the bolts or outer panels of the
compressor.
■ When the outdoor unit is installed above the indoor unit the
following can occur:
The condensated water on the stop valve can move to the
indoor unit. To avoid this, please cover the stop valve with
sealing material.
■ If the temperature is higher than 30°C and the humidity is higher
than RH 80%, then the thickness of the sealing materials should
be at least 20 mm in order to avoid condensation on the surface
of the sealing.
■ Be sure to insulate the liquid and gas-side field piping and the
refrigerant branch kit.
Any exposed piping may cause condensation or burns
if touched.
(The highest temperature that the gas-side piping can reach is
around 120°C, so be sure to use insulating material which is
very resistant.)

EVACUATING
■ Do not purge the air with refrigerants. Use a vacuum pump to
vacuum the installation. No additional refrigerant is provided for
air purging.
■ Pipes inside the units were checked for leaks by the
manufacturer. The refrigerant pipes fit on site are to be checked
for leaks by the installer.
■ Confirm that the valves are firmly closed before leak test or
vacuuming.

9 Pipe branching kit (optional)
■ After completing the installation, carry out a gas leak inspection
of the piping connections with nitrogen and such.
Cautions for necessity of a trap
Since there is fear of the oil held inside the riser piping flowing back
into the compressor when stopped and causing liquid compression
phenomenon, or cases of deterioration of oil return, it will be
necessary to provide a trap at an appropriate place in the riser gas
piping.
■ Tr ap installation spacing. (See figure 5)

C Gas piping
D Liquid piping
E Oiltrap
H Install trap at each difference in height of 15 m.
■ A trap is not necessary when the outdoor unit is installed in a
higher position than the indoor unit.
Cautions for brazing
■ Be sure to carry out a nitrogen blow when brazing.
Brazing without carrying out nitrogen replacement or releasing
nitrogen into the piping will create large quantities of oxidized
film on the inside of the pipes, adversely affecting valves and
compressors in the refrigerating system and preventing normal
operation.
■ When brazing while inserting nitrogen into the piping, nitrogen
must be set to 0.02 MPa with a pressure-reducing valve (=just
enough so that it can be felt on the skin).
12 345
Procedure for leak test
Leak test must satisfy EN378-2.
1
Evacuate the pipes and check vacuum
increase for 1 minute.)
2
Break the vacuum with a minimum of 2 bar of nitrogen. (Never
pressurize more than 3.3 MPa.)
3
Conduct leak test by applying soap water, etc. to the connecting
part of the pipes.
4
Discharge nitrogen.
5
Evacuate and check vacuum again
6
If vacuum gauge does no longer rise, the stop valves can be
openend.
(1) Use a vacuum pump which can evacuate to –100.7 kPa
(5 Torr, –755 mmHg).
Evacuate the system from the liquid and gas pipes by using
a vacuum pump for more than 2 hours and bring the system
to –100.7 kPa. After keeping the system under that condition
for more than one hour, check if the vacuum gauge rises or
not. If it rises, the system may either contain moisture inside
or have leaks.
Following should be executed if there is a possibility of
moisture remaining in the pipe (if piping work is carried out
during the raining season or over a long period of time,
rainwater may enter the pipe during work).
After evacuating the system for 2 hours, pressurize the
system to 0.05 MPa (vacuum break) with nitrogen gas and
evacuate the system again using the vacuum pump for
1 hour to –100.7 kPa (vacuum drying). If the system
cannot be evacuated to –100.7 kPa within 2 hours, repeat
the operation of vacuum break and vacuum drying. Then
after leaving the system in vacuum for 1 hour, confirm that
the vacuum gauge does not rise.

CHARGING REFRIGERANT
Example 1
Precaution for servicing
When performing service on the unit requiring the
refrigerant system to be opened, refrigerant must be
evacuated according to local regulations.
This unit requires additional charging of refrigerant according to the
length of pipe connected at the site. Charge the refrigerant to the
liquid pipe in its liquid state. Since R-407C is a mixed refrigerant, its
composition changes if charged in a state of gas and normal system
operation would no longer be assured.
On this model it is not necessary to charge additionaly if the piping
length ≤30 m.
On twin/triple application, piping length means sum of
main pipe and branch pipe.
Piping length is the 1 way length, gas or liquid.
Over 30 m or for complete recharging, please charge based as
shown in figure 2, figure 3 and figure 4, where the pipe length is
respectively L1, L1+L2+L3 and L1+L2+L3+L4.
Additional charging of refrigerant
■ Over 30 m please, add refrigerant quantity according to following
table.
For future servicing, mark with a circle the selected amount on the
tables below

Precaution for pumping-down operation
Precautions on electrical wiring work
The outdoor unit is equipped with a low-pressure switch to protect the
compressor.
Never short-circuit the low pressure switch in this
operation.
Ta ke the following steps to perform the pumping-down operation.
Procedure Precaution
1
Put a pressure gauge at the
service port of the gas stop
valve.
2
Start the fan operation with the
remote controller.
Use a pressure gauge
reserved for R-407C
exclusively.
Confirm that stop valves both
on the liquid and gas side are
open.
3
Push the pumping-down
button on the PC board of the
outdoor unit.
Compressor and outdoor fan
will start operation
automatically.
If step 3 is performed before
step 2, then the indoor fan
may automatically start
running. Please pay attention
to this.
4
Continue operation for
—
2 minutes until operation
condition stabilizes.
5
Close the stop valve on the
liquid side securely. (See "How
to use the shut-off valve" on
Insecure closing of the valve
may result in burning of the
compressor.
page 6)
6
When the low-pressure switch
is activated, the unit stops
working. At this time, close the
stop valve on the gas side.
If the low pressure switch
(S1PL) does not activate,
close the stop valve at the gas
side after confirming the
remaining pressure on the
pressure gauge and shut
down the power supply.
This is the end of pumping-down operation. After pumping-down
operation, the remote controller can show the following pattern:
- "U4"
-blank screen
- indoor fan operates for about 30 seconds
even when ON button on the remote controller is pressed, and it will
not operate. Turn off the main power supply switch and turn it on
again in need of operation.
■ Before obtaining access to terminal devices, all supply circuits
must be interrupted.
■ Use only copper wires.
■ The wiring between the indoor unit and outdoor unit must be for
220~240V.
■ Do not turn on the main switch until all the wiring is completed.
■ For W1
Make sure to connect power supply cables in normal phase. If
connected in reverse phase, the remote controller of indoor unit
indicates "U1" and the equipment cannot operate. Change any
two of the three power supply cables (L1, L2, L3) to correct
phase.
If the contact in the magnetic switch should be forcibly turned on
while the equipment is inoperative, the compressor will burn out.
Never try to forcibly turn on the contact.
■ Never squeeze bundled cables into a unit.
■ Fix cables so that cables do not make contact with the pipes
(especially on high pressure side).
■ Secure the electrical wiring with clamping material as shown in
the figure below so that it does not come in contact with the
piping, particulary on the high-pressure side.
Make sure no external pressure is applied to the terminal
connectors.
Secure the wiring in the order shown below.
1 Secure the ground wire to the shut-off valve attachment plate so
that it does not slide.
2 Secure the ground wire to the shut-off valve attachment plate
one more time along with the electric wiring and the inter-unit
wiring.
■ Lay the electrical wiring so that the front cover does not rise up
when doing wiring work and attach the front cover securely.

Precautions on wiring of power supply and inter-unit wiring
■ Use a round crimp-style terminal for
connection to the power supply
terminal board. In case it cannot be
used due to unavoidable reasons,
be sure to observe the following
instruction.
- Do not connect wires of different gauge to the same power
supply terminal. (Looseness in the connection may cause
overheating.)
- When connecting wires of the same gauge, connect them
according to the below figure.
■ Use the correct screwdriver to tighten the terminal screws.
Small screwdrivers can damage the screw head and prevent
appropriate tightening.
■ Over-tightening the terminal screws can damage the screws.
■ See the tabel below for tightening torques for the terminal
screws.
