Refrigerant piping
Relocation
•
Install the refrigerant pipe securely during the installation work before operating the air conditioner. If the compressor is
operated with the valve open and without refrigerant pipe, the compressor sucks air and the refrigeration cycles is over
pressurized, which may cause a injury.
•
Only a qualified installer(*1) or qualified service person(*1) is allowed to relocate the air conditioner. It is dangerous for the
air conditioner to be relocated by an unqualified individual since a fire, electric shocks, injury, water leakage, noise and/or
vibration may result.
•
•
•
•
Tighten the flare nut with a torque wrench in the specified manner. Excessive tighten of the flare nut may cause a crack in
the flare nut after a long period, which may result in refrigerant leakage.
Ventilate the air if the refrigerant gas leaks during installation. If the leaked refrigerant gas comes into contact with fire, toxic
gas may be produced.
After the installation work, confirm that refrigerant gas does not leak. If refrigerant gas leaks into the room and flows near a
fire source, such as a cooking range, noxious gas may be generated.
When the air conditioner has been installed or relocated, follow the instructions in the Installation Manual and purge the air
completely so that no gases other than the refrigerant will be mixed in the refrigerating cycle. Failure to purge the air
completely may cause the air conditioner to malfunction.
•
When carrying out the pump-down work shut down the compressor before disconnecting the refrigerant pipe. Disconnecting
the refrigerant pipe with the service valve left open and the compressor still operating will cause air or other gas to be sucked
in, raising the pressure inside the refrigeration cycle to an abnormally high level, and possibly resulting in rupture, injury or
other trouble.
Never recover the refrigerant into the outdoor unit. Be sure to use a refrigerant recovery machine to recover the refrigerant
when moving or repairing. It is impossible to recover the refrigerant into the outdoor unit. Refrigerant recovery into the
outdoor unit may result in serious accidents such as explosion of the unit, injury or other accidents.
•
(*1) Refer to the “Definition of Qualified Installer or Qualified Service Person.”
•
•
•
Nitrogen gas must be used for the airtight test.
The charge hose must be connected in such a way that it is not slack.
If refrigerant gas has leaked during the installation work, ventilate the room immediately. If the leaked refrigerant gas comes
in contact with fire, noxious gas may be generated.

Electrical wiring
•
•
•
•
Only a qualified installer(*1) or qualified service person(*1) is allowed to carry out the electrical work of the air conditioner.
Under no circumstances must this work be done by an unqualified individual since failure to carry out the work properly may
result in electric shocks and/or electrical leaks.
When connecting the electrical wires, repairing the electrical parts or undertaking other electrical jobs, wear gloves to
provide protection for electricians and from heat, insulating shoes and clothing to provide protection from electric shocks.
Failure to wear this protective gear may result in electric shocks.
When executing address setting, test run, or troubleshooting through the checking window on the electric parts box, put on
insulated heat-proof gloves, insulated shoes and other clothing to provide protection from electric shock. Otherwise you may
receive an electric shock.
•
The characteristics of R410A refrigerant are; easy to absorb water, oxidizing membrane or oil, and its pressure is approx.
1.6 times higher than that of refrigerant R22. Accompanied with the new refrigerant, refrigerating oil has also been changed.
Therefore, during installation work, be sure that water, dust, former refrigerant, or refrigerating oil does not enter the
refrigerating cycle.
•
To prevent charging an incorrect refrigerant and refrigerating oil, the sizes of connecting sections of charging port of the
main unit and installation tools are changed from those for the conventional refrigerant.
•
•
Use wiring that meets the specifications in the Installation Manual and the stipulations in the local regulations and laws. Use
of wiring which does not meet the specifications may give rise to electric shocks, electrical leakage, smoking and/or a fire.
Check that the product is properly earthed. (grounding work)
•
•
Accordingly the exclusive tools are required for the new refrigerant (R410A).
Incomplete earthing may cause electric shock.
For connecting pipes, use new and clean piping designed for R410A, and please care so that water or dust does not enter.
•
•
•
Do not connect the earth line to a gas pipe, water pipe, lightning conductor, or a telephone earth line.
After completing the repair or relocation work, check that the ground wires are connected properly.
Install a circuit breaker that meets the specifications in the installation manual and the stipulations in the local regulations
and laws.
To Disconnect the Appliance from Main Power Supply.
This appliance must be connected to the main power supply by means of a switch with a contact separation of at least 3 mm.
•
•
•
•
Install the circuit breaker where it can be easily accessed by the agent.
The installation fuse (all type can be used) must be used for the power supply line of this conditioner.
When installing the circuit breaker outdoors, install one which is designed to be used outdoors.
Under no circumstances must the power cable be extended. Connection trouble in the places where the cable is extended
may give rise to smoking and/or a fire.
•
•
•
Electrical wiring work shall be conducted according to law and regulation in the community and installation manual.
Failure to do so may result in electrocution or short circuit.
Do not supply power from the power terminal block equipped on the outdoor unit to another outdoor unit. Capacity overflow
may occur on the terminal block and may result in fire.
When carrying out electric connection, use the wire specified in the Installation Manual and connect and fix the wires
securely to prevent them applying external force to the terminals. Improper connection or fixing may result in fire.
Test run
•
Before operating the air conditioner after having completed the work, check that the electrical parts box cover of the indoor
unit and service panel of the outdoor unit are closed, and set the circuit breaker to the ON position. You may receive an
electric shock if the power is turned on without first conducting these checks.
•
When you have noticed that some kind of trouble (such as when an error display has appeared, there is a smell of burning,
abnormal sounds are heard, the air conditioner fails to cool or heat or water is leaking) has occurred in the air conditioner,
do not touch the air conditioner yourself but set the circuit breaker to the OFF position, and contact a qualified service
person. Take steps to ensure that the power will not be turned on (by marking “out of service” near the circuit breaker, for
instance) until qualified service person arrives. Continuing to use the air conditioner in the trouble status may cause
mechanical problems to escalate or result in electric shocks or other failure.
•
•
After the work has finished, be sure to use an insulation tester set (500V Megger) to check the resistance is 2 MΩ or more
between the charge section and the non-charge metal section (Earth section). If the resistance value is low, a disaster such
as a leak or electric shock is caused at user’s side.
Upon completion of the installation work, check for refrigerant leaks and check the insulation resistance and water drainage.
Then conduct a test run to check that the air conditioner is operating properly.
Explanations given to user
•
Upon completion of the installation work, tell the user where the circuit breaker is located. If the user does not know where
the circuit breaker is, he or she will not be able to turn it off in the event that trouble has occurred in the air conditioner.
If you have discovered that the fan grille is damaged, do not approach the outdoor unit but set the circuit breaker to the OFF
position, and contact a qualified service person(*1) to have the repairs done. Do not set the circuit breaker to the ON position
until the repairs are completed.

This air conditioner adopts the new HFC refrigerant (R410A) which does not deplete the ozone layer.
• R410A refrigerant is vulnerable to impurities such as water, oxidizing membranes, or oils because the pressure
of R410A refrigerant is higher than that of the former refrigerant by approximately 1.6 times.
As well as the adoption of the new refrigerant, the refrigerating oil has been also changed. Therefore, pay
attention so that water, dust, former refrigerant, or refrigerating oil does not enter the refrigerating cycle of the
new refrigerant air conditioner during installation.
• To prevent mixing of refrigerant or refrigerating oil, the size of the charge port of the main unit or connecting
section of the installation tool differs to that of an air conditioner for the former refrigerant.
Accordingly, exclusive tools are required for the new refrigerant (R410A) as shown below.

• Be sure to use a header unit for the leading outdoor unit to be connected to the main pipe. (Figure 1 and 3)
• Be sure to use a T-shaped branch joint (RBM-BT14E/RBM-BT24E: separately purchased) to connect each
outdoor unit.
• Be careful of the direction of the Outdoor unit connection piping kit for the liquid side. (As shown in Figure 2, a
Outdoor unit connection piping kit cannot be attached so that the refrigerant of the main pipe flows directly into
the header unit.)

• Adding only one follower unit is possible. Install the additional unit so that its position is opposite to the header
unit. Use an extension valve for installation (See the figure above.).
Specify the pipe diameter in advance to allow for adding another unit.
Piping/wiring panel
(Rear piping)
• When drawing out the pipe forward, draw it out to the
outside via the piping/wiring panel, and leave a space
of 500mm or more from the main pipe connecting the
outdoor unit with the indoor unit, considering service
work or other work on the unit. (For replacing the
compressor, 500mm or more space is required.)
• When drawing out the pipe downward, remove the
knockouts on the base plate of the outdoor unit, draw
the pipes out of the outdoor unit, and perform piping on

For an airtight test, connect a nitrogen gas canister as shown in the figure on the next page and apply pressure.
• Be sure to apply pressure from the service ports of the packed valves (or ball valves) at the liquid side, gas side
and balance pipe side.
• An airtight test can only be performed at the service ports at the liquid side, gas side and balance pipe side on
header unit.

• Close the valves fully at the gas side, liquid side and balance pipe side. As there is a possibility that the nitrogen
gas will enter into the cycle of outdoor units, re-tighten the valve rods at the liquid side and balance pipe side
before applying pressure.
(When using MAP140 or MAP160, you do not have to re-tighten the liquid side valve rod as their valves at the
liquid side are ball valves.)
◆Cautions for installation
• Set the outdoor unit first connected to the bridging pipe to the indoor units as the header unit.
• Install the outdoor units in order of their capacity codes: A (header unit) ≥ B ≥ C ≥ D
• When connecting gas pipes to indoor units, use Y-shaped branching joints to keep pipes level.
• When piping to outdoor units using Outdoor unit connection piping kits, intersect the pipes to the outdoor unit
and those to indoor units at a right angle as shown in figure 1 on “6. INSTALLATION OF THE OUTDOOR UNIT”.
Do not connect them as in figure 2 on “6. INSTALLATION OF THE OUTDOOR UNIT”.
• For each refrigerant line, apply pressure gradually in steps at the liquid side, gas side and balance pipe side.
Be sure to apply pressure at the gas side, liquid side, and balance pipe side.
WARNING
Never use oxygen, flammable gases, or noxious gases in an airtight test.

„Vacuum drying
However, if the environmental temperature changes from the moment of applying pressure to 24 hours after that, the pressure
will change by about 0.01MPa (0.1kg/cm²G) per 1°C. Consider the pressure change when checking the test result.
• Be sure to perform vacuuming from both liquid and gas sides.
• Be sure to use a vacuum pump equipped with the counter-flow prevention function so that oil in the pump will
not flow back into piping for air conditioners. (If oil in the vacuum pump enters in the air conditioner with R410A
refrigerant, a problem may be caused in the refrigerating cycle.)
REQUIREMENT
When pressure decrease is detected in steps 1-3, check the leakage at the connecting points.
Check the leakage using a foaming agent or other measures and seal the leak with re-brazing, flare retightening or other
methods. After sealing, execute an airtight test again.
After finishing the airtight test and discharging nitrogen gas, connect the gauge manifold to the service ports of the liquid side,
gas side, and balance pipe side and connect a vacuum pump as shown in the figure below. Be sure to perform vacuuming for
the liquid, gas, and balance pipe sides.

• Use a vacuum pump with a high vacuuming degree [-100.7kPa (5Torr, -755mmHg)] and large exhaust gas
amount (40L/minute or larger).
• Perform vacuuming for 2 or 3 hours, though the time differs depending on the pipe length. Check that all the
packed valves at the liquid side, gas side, and balance pipe side are fully closed.
• If the pressure does not reach -100.7kPa or less, continue vacuuming for 1 hour or more. If the pressure does
not reach -100.7kPa after 3 hours of vacuuming, stop vacuuming and check for air leakage.
• If the pressure reaches -100.7kPa or less after vacuuming for 2 hours or more, close the valves VL and VH on
the gauge manifold fully and stop the vacuum pump. Leave it as it is for 1 hour to confirm that the vacuuming
degree does not change.
If the degree of vacuum loss is large, moisture may remain in the pipes. In that case, inject dry nitrogen gas and
apply pressure to 0.05MPa and perform vacuuming again.
• After finishing the above procedure of vacuuming, exchange the vacuum pump with a refrigerant canister and
advance to the additional charging of refrigerant.

Charging of refrigerant
• Keeping the valve of the outdoor unit closed, be sure to charge the liquid refrigerant into the service port at the
liquid side.
• If the specified amount of refrigerant cannot be charged, fully open the valves of the outdoor unit at liquid and
gas sides, operate the air conditioner in COOL mode, and then charge refrigerant into service port at the gas
side. In this time, choke the refrigerant slightly by operating the valve of the canister to charge liquid refrigerant.
• The liquid refrigerant may be charged suddenly, therefore be sure to charge refrigerant gradually.

at the interface point between the user’s supply and the public system. It is the responsibility of the installer or user of the
equipment to ensure, by consultation with the distribution network operator if necessary, that the equipment is connected
only to a supply with a short-circuit power Ssc greater than or equal to Ssc (*1)
CAUTION
• Be sure to complete the electric wiring before setting the addresses.
• If you turn on the outdoor unit before turning on the indoor units, the CODE No. [E19] is indicated on the 7-
segment display on the interface P.C. board of the outdoor unit until the indoor units are turned on. This is not a
malfunction.
Furthermore, when similar equipment or other equipment which may cause harmonic current emissions are to be
connected to the same interface point with this equipment, to reduce the risk of possible problems which may be caused
from addition of those harmonic current emissions, it is recommended to make sure that the short-circuit power Ssc at the
interface point is greater than the sum of the minimum Ssc required by all the equipment which will be connected to the
interface point.
• It may take up to ten minutes (normally about five minutes) to address one refrigerant line automatically.
• Settings on the outdoor unit are required for automatic addressing. (Address setting is not started simply by
turning on the power.)
• Running the unit is not required for address setting.
• The addresses can be set manually.

WARNINGS ON REFRIGERANT LEAKAGE
Check of Concentration Limit
Important
The room in which the air conditioner is to be installed
requires a design that in the event of refrigerant gas
leaking out, its concentration will not exceed a set limit.
The refrigerant R410A which is used in the air conditioner is
safe, without the toxicity or combustibility of ammonia, and is
not restricted by laws to be imposed which protect the ozone
layer. However, since it contains more than air, it poses the
risk of suffocation if its concentration should rise excessively.
Suffocation from leakage of R410A is almost non-existent.
With the recent increase in the number of high concentration
buildings, however, the installation of multi air conditioner
systems is on the increase because of the need for effective
use of floor space, individual control, energy conservation by
curtailing heat and carrying power etc.
Most importantly, the multi air conditioner system is able to
replenish a large amount of refrigerant compared with
conventional individual air conditioners. If a single unit of the
multi conditioner system is to be installed in a small room,
select a suitable model and installation procedure so that if
the refrigerant accidentally leaks out, its concentration does
not reach the limit (and in the event of an emergency,
measures can be made before injury can occur).
NOTE 2 :
The standards for minimum room volume are as
follows.
(1) No partition (shaded portion)
(2) When there is an effective opening with the adjacent
room for ventilation of leaking refrigerant gas (opening
without a door, or an opening 0.15% or larger than the
respective floor spaces at the top or bottom of the door).
Outdoor unit
Refrigerant piping
Indoor unit
In a room where the concentration may exceed the limit,
create an opening with adjacent rooms, or install mechanical
ventilation combined with a gas leak detection device.
The concentration is as given below.
(3) If an indoor unit is installed in each partitioned room and
the refrigerant piping is interconnected, the smallest
room of course becomes the object. But when a
mechanical ventilation is installed interlocked with a gas
leakage detector in the smallest room where the density
limit is exceeded, the volume of the next smallest room
becomes the object.
