NOTE
A direct current motor is adopted for indoor fan motor in the Concealed Duct Standard Type air conditioner. Caused from its characteristics, a current limit works on the direct current motor. When replacing the high-performance filter or when opening the service board, be sure to stop the fan. If an above action is executed during the fan operation, the protective control works to stop the unit operation, and the check code “P12” may be issued. However it is not a trouble. When the desired operation has finished, be sure to reset the system to clear “P12” error code using the leak breaker of the indoor unit. Then push the operation stop button of the remote controller to return to the usual operation.

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.
Insulating measures
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 |
No fire |
|
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. |
|
|
|
|
|
Do not use any refrigerant different from the one specified for complement or replacement. |
|
|
Otherwise, abnormally high pressure may be generated in the refrigeration cycle, which may |
|
|
result in a failure or explosion of the product or an injury to your body. |
|
|
|
|
|
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. |
|
|
|
|
|
Do not charge refrigerant additionally. |
|
|
If charging refrigerant additionally when refrigerant gas leaks, the refrigerant composition in the |
|
Refrigerant |
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. |
|
|
|
|
|
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 |

|
|
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. |

|
|
Ventilation |
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 generate. |

|
|
|
|
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. |
– 9 –
|
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. |

|
|
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. |

|
|
|
Tighten the flare nut with a torque wrench in the specified manner. |
|
Compulsion |
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. |

Only a qualified installer or service person is allowed to do installation work. Inappropriate installation may result in water leakage, electric shock or fire.
Before starting to install the air conditioner, read carefully through the Installation Manual, and follow its instructions to install the air conditioner.
If the unit is installed in a small room, take appropriate measures to prevent the refrigerant from exceeding the limit concentration even if it leaks. Consult the dealer from whom you purchased the air conditioner when you implement the measures. Accumulation of highly-concentrated refrigerant may cause an oxygen deficiency accident.
|
Do not install the air conditioner in a location that may be subject to a risk of expire to a |
|
combustible gas. |
Installation |
If a combustible gas leaks and becomes concentrated around the unit, a fire may occur. |
Install the indoor unit at least 2.5 m above the floor level since otherwise the users may injure themselves or receive electric shocks if they poke their fingers or other objects into the indoor unit while the air conditioner is running.
Install a circuit breaker that meets the specifications in the installation manual and the stipulations in the local regulations and laws.
Install the circuit breaker where it can be easily accessed by the agent.
Do not place any combustion appliance in a place where it is directly exposed to the wind of air conditioner, otherwise it may cause imperfect combustion.
When mounting the rails, push them until the 3 latches click.
Insert the filters into the direction which the arrows, carved on the filters, show. (2 filters are identical)

Explanations given to user
•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 to have the repairs done. Do not set the circuit breaker to the ON position until the repairs are completed.
Relocation
•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.
•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.

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.
