Do not bring
a child close
to the equipment.
If, in the course of carrying out repairs, it becomes absolutely necessary to check out the electrical parts
with the electrical parts box cover of one or more of the indoor units and the service panel of the outdoor
unit removed in order to find out exactly where the trouble lies, put a sign in place so that no-one will
approach the work location before proceeding with the work.
Third-party individuals may enter the work site and receive electric shocks if this warning is not heeded.
Insulating
measures
No fire
Refrigerant
Connect the cut-off lead wires with crimp contact, etc., put the closed end side upward and then apply a
water-cut method, otherwise a leak or production of fire is caused at the users’ side.
When performing repairs using a gas burner, replace the refrigerant with nitrogen gas because the oil that
coats the pipes may otherwise burn.
When repairing the refrigerating cycle, take the following measures.
1) Be attentive to fire around the cycle. When using a gas stove, etc., be sure to put out fire before work;
otherwise the oil mixed with refrigerant gas may catch fire.
2) Do not use a welder in the closed room. When using it without ventilation, carbon monoxide poisoning
may be caused.
3) Do not bring inflammables close to the refrigerant cycle, otherwise fire of the welder may catch the
inflammables.
The refrigerant used by this air conditioner is the R410A.
Check the used refrigerant name and use tools and materials of the parts which match with it.
For the products which use R410A refrigerant, the refrigerant name is indicated at a position on the
outdoor unit where is easy to see. To prevent miss-charging, the route of the service port is changed from
one of the former R22.
For an air conditioner which uses R410A, never use other refrigerant than R410A. For an air conditioner
which uses other refrigerant (R22, etc.), never use R410A.
If different types of refrigerant are mixed, abnormal high pressure generates in the refrigerating cycle and
an injury due to breakage may be caused.
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.
Do not charge refrigerant additionally. If charging refrigerant additionally when refrigerant gas leaks, the
refrigerant composition in the refrigerating cycle changes resulted in change of air conditioner
characteristics or refrigerant over the specified standard amount is charged and an abnormal high
pressure is applied to the inside of the refrigerating cycle resulted in cause of breakage or injury.
Therefore if the refrigerant gas leaks, recover the refrigerant in the air conditioner, execute vacuuming,
and then newly recharge the specified amount of liquid refrigerant.
In this time, never charge the refrigerant over the specified amount.
Assembly/Wiring
Insulator check
Ventilation
When recharging the refrigerant in the refrigerating cycle, do not mix the refrigerant or air other than
R410A into the specified refrigerant.
If air or others is mixed with the refrigerant, abnormal high pressure generates in the refrigerating cycle
resulted in cause of injury due to breakage.
After installation work, check the refrigerant gas does not leak.
If the refrigerant gas leaks in the room, poisonous gas generates when gas touches to fire such as fan
heater, stove or cocking stove though the refrigerant gas itself is innocuous.
Never recover the refrigerant into the outdoor unit.
When the equipment is moved or repaired, be sure to recover the refrigerant with recovering device.
The refrigerant cannot be recovered in the outdoor unit; otherwise a serious accident such as breakage or
injury is caused.
After repair work, surely assemble the disassembled parts, and connect and lead the removed wires as before.
Perform the work so that the cabinet or panel does not catch the inner wires.
If incorrect assembly or incorrect wire connection was done, a disaster such as a leak or fire is caused at
user’s side.
After the work has finished, be sure to use an insulation tester set (500V Megger) to check the resistance
is 1MΩ or more between the charge section and the non-charge metal section (Earth position).
If the resistance value is low, a disaster such as a leak or electric shock is caused at user’s side.
When the refrigerant gas leaks during work, execute ventilation.
If the refrigerant gas touches to a fire, poisonous gas generates.
A case of leakage of the refrigerant and the closed room full with gas is dangerous because a shortage of
oxygen occurs. Be sure to execute ventilation.
8
When the refrigerant gas leaks, find up the leaked position and repair it surely.
If the leaked position cannot be found up and the repair work is interrupted, pump-down and tighten the
service valve, otherwise the refrigerant gas may leak into the room.
The poisonous gas generates when gas touches to fire such as fan heater, stove or cocking stove though
the refrigerant gas itself is innocuous.
When installing equipment which includes a large amount of charged refrigerant such as a multi air
conditioner in a sub-room, it is necessary that the density does not the limit even if the refrigerant leaks.
If the refrigerant leaks and exceeds the limit density, an accident of shortage of oxygen is caused.
Compulsion
Check after
repair
Do not operate
the unit with
the valve closed.
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.
Nitrogen gas must be used for the airtight test.
The charge hose must be connected in such a way that it is not slack.
For the installation/moving/reinstallation work, follow to the Installation Manual.
If an incorrect installation is done, a trouble of the refrigerating cycle, water leak, electric shock or fire is caused.
Once the repair work has been completed, check for refrigerant leaks, and check the insulation resistance
and water drainage. Then perform a trial run to check that the air conditioner is running properly.
After repair work has finished, check there is no trouble.
If check is not executed, a fire, electric shock or injury may be caused.
For a check, turn off the power breaker.
After repair work (installation of front panel and cabinet) has finished, execute a test run to check there is
no generation of smoke or abnormal sound.
If check is not executed, a fire or an electric shock is caused. Before test run, install the front panel and cabinet.
Be sure to fix the screws back which have been removed for installation or other purposes.
Check the following matters before a test run after repairing piping.
• Connect the pipes surely and there is no leak of refrigerant.
• The valve is opened.
Running the compressor under condition that the valve closes causes an abnormal high pressure resulted
in damage of the parts of the compressor and etc. and moreover if there is leak of refrigerant at connecting
section of pipes, the air is sucked and causes further abnormal high pressure resulted in burst or injury.
Check after
reinstallation
Cooling check
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.
Check the following items after reinstallation.
1) The earth wire is correctly connected.
2) The power cord is not caught in the product.
3) There is no inclination or unsteadiness and the installation is stable.
If check is not executed, a fire, an electric shock or an injury is caused.
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, etc. to be sucked in, raising the pressure inside the refrigeration cycle to an abnormally high
level, and possibly resulting in reputing, injury, etc.
When the service panel of the outdoor unit is to be opened in order for the compressor or the area around
this part to be repaired immediately after the air conditioner has been shut down, set the circuit breaker to
the OFF position, and then wait at least 10 minutes before opening the service panel.
If you fail to heed this warning, you will run the risk of burning yourself because the compressor pipes and
other parts will be very hot to the touch. In addition, before proceeding with the repair work, wear the kind
of insulated heat-resistant gloves designed to protect electricians.
Take care not to get burned by compressor pipes or other parts when checking the cooling cycle while
running the unit as they get heated while running.
Be sure to put on gloves providing protection for electric shock and heat.
When the service panel of the outdoor unit is to be opened in order for the fan motor, reactor, inverter or
the areas around these parts to be repaired immediately after the air conditioner has been shut down, set
the circuit breaker to the OFF position, and then wait at least 10 minutes before opening the service panel.
If you fail to heed this warning, you will run the risk of burning yourself because the fan motor, reactor,
inverter heat sink and other parts will be very hot to the touch.
In addition, before proceeding with the repair work, wear the kind of insulated heat-resistant gloves
designed to protect electricians.

• New Refrigerant (R410A)
This air conditioner adopts a new HFC type refrigerant (R410A) which does not deplete the ozone layer.
1. Safety Caution Concerned to New Refrigerant
The pressure of R410A is high 1.6 times of that of the former refrigerant (R22).
Accompanied with change of refrigerant, the refrigerating oil has been also changed.
Therefore, be sure that water, dust, the former refrigerant or the former refrigerating oil is not mixed into
the refrigerating cycle of the air conditioner with new refrigerant during installation work or service work.
If an incorrect work or incorrect service is performed, there is a possibility to cause a serious accident.
Use the tools and materials exclusive to R410A to purpose a safe work.
2. Cautions on Installation/Service
(1) Do not mix the other refrigerant or refrigerating oil.
For the tools exclusive to R410A, shapes of all the joints including the service port differ from those
of the former refrigerant in order to prevent mixture of them.
(2) As the use pressure of the new refrigerant is high, use material thickness of the pipe and tools
which are specified for R410A.
(3) In the installation time, use clean pipe materials and work with great attention so that water and
others do not mix in because pipes are affected by impurities such as water, oxide scales, oil, etc.
Use the clean pipes.
Be sure to brazing with flowing nitrogen gas. (Never use gas other than nitrogen gas.)
(4) For the earth protection, use a vacuum pump for air purge.
(5) R410A refrigerant is azeotropic mixture type refrigerant.
Therefore use liquid type to charge the refrigerant. (If using gas for charging, composition of the
refrigerant changes and then characteristics of the air conditioner change.)
3. Pipe Materials
For the refrigerant pipes, copper pipe and joints are mainly used.
It is necessary to select the most appropriate pipes to conform to the standard.
Use clean material in which impurities adhere inside of pipe or joint to a minimum.
(1) Copper pipe
<Piping>
The pipe thickness, flare finishing size, flare nut and others differ according to a refrigerant type.
When using a long copper pipe for R410A, it is recommended to select “Copper or copper-base pipe without
seam” and one with bonded oil amount 40mg/10m or less.
Also do not use crushed, deformed, discolored (especially inside) pipes. (Impurities cause clogging of
expansion valves and capillary tubes.)
<Flare nut>
Use the flare nuts which are attached to the air conditioner unit.
(2) Joint
The flare joint and socket joint are used for joints of the copper pipe.
The joints are rarely used for installation of the air conditioner.
However clear impurities when using them.

4. Tools
(1) Required Tools for R410A
Mixing of different types of oil may cause a trouble such as generation of sludge, clogging of
capillary, etc. Accordingly, the tools to be used are classified into the following three types.
1) Tools exclusive for R410A (Those which cannot be used for conventional refrigerant (R22))
2) Tools exclusive for R410A, but can be also used for conventional refrigerant (R22)
3) Tools commonly used for R410A and for conventional refrigerant (R22)
The table below shows the tools exclusive for R410A and their interchangeability.
