Items to be strictly observed :
1.Pressurize the equipment with nitrogen up to the design pressure and then judge the equipment's air tightness, taking
temperature variations into account.
2.When investigating leakage locations using a refrigerant, be sure to use R410A.
3.Ensure that R410A is in a liquid state when charging.
Reasons:
Use of oxygen as the pressurized gas may cause an explosion.
1.
2.
Charging with R410A gas will lead the composition of the remaining refrigerant in the cylinder to change and then this
refrigerant can not be used.
Vacuuming
1.Vacuum pump with check valve
A vacuum pump with a check valve is required to prevent the vacuum pump oil from flowing back into the refrigerant
circuit when the vacuum pump power is turned off (power failure). It is also possible to attach a check valve to the actual
vacuum pump afterwards.
2.Standard degree of vacuum for the vacuum pump
Use a pump which reaches 65Pa or below after 5 minutes of operation.
In addition, be sure to use a vacuum pump that has been properly maintained and oiled using the specified oil. If the
vacuum pump is not properly maintained, the degree of vacuum may be too low.
3.Required accuracy of the vacuum gauge
Use a vacuum gauge that can measure up to 650Pa. Do not use a general gauge manifold since it cannot measure a
vacuum of 650Pa.
4.Evacuating time
Evacuate the equipment for 1 hour after 650Pa has been reached.
After envacuating, leave the equipment for 1 hour and make sure the that vacuum is not lost.
5.Operating procedure when the vacuum pump is stopped
In order to prevent a backflow of the vacuum pump oil, open the relief valve on the vacuum pump side or loosen the
charge hose to drawn in air before stopping operation.The same operating procedure should be used when using a
vacuum pump with a check valve.
Charging Refrigerant
R410A must be in a liquid state when charging.
Reasons:
R410A is a pseudo-azeotropic refrigerant (boiling point R32= -52 C, R125= -49 C) and can roughly be handled in the same
way as R22; however, be sure to fill the refrigerant from the liquid side, for doing so from the gas side will somewhat change
the composition of the refrigerant in the cylinder.
Note
In the case of a cylinder with a syphon, liquid R410A is charged without turning the cylinder up side down. Check the
type of cylinder before charging.
Remedies to be taken in case of a refrigerant leak
When refrigerant leaks, additional refrigerant may be charged. (Add the refrigerant from the liquid side)
Characteristics of the Conventional and the New Refrigerants
Because R410A is a simulated azeotropic refrigerant, it can be handled in almost the same mammer as a single refrigerant
such as R22. Howerver, if the refrigerant is removed in the vapor phase, the composition of the refrigerant in the cylinder
will somewhat change.
Remove the refrigerant in the liquid phase. Additional refrigerant may be added in case of a refrigerant leak.

20. Setting method of temperature compensation Tcomp
A. Wired control type unit: this function is not available
B. Remote control type unit:
In cooling or heating mode, there is always with the temp. compensation.
In heating mode: In 24℃ heating mode, press SLEEP(or SWING) button 7 times continuously within 5
seconds, indoor buzzer sounds twice, that shows temp. compensation works. Switch on the unit in
heating mode by the remote controller, press TEMP button to set the set temp., so temperature
compensation=the current set temp. - 24℃. For example, if the set temp. is 24℃, the temp.
compensation is 0℃; if the set temp. is 25℃, the temp. compensation is 1℃. The max. compensation
temp. is 6℃ (the set temp. is 30℃). If you want to cancel it, set the temp. as 24℃.
In cooling mode: In 24℃ cooling mode, press SLEEP(or SWING) button 7 times continuously within 5
seconds, indoor buzzer sounds twice, that shows temp. compensation works. Switch on the unit in
heating mode by the remote controller, press TEMP button to set the set temp., so temperature
compensation=24℃-the current set temp. . For example, if the set temp. is 24℃, the temp.
compensation is 0℃; if the set temp. is 23℃, the temp. compensation is -1℃. The max. compensation
temp. is -8℃ (the set temp. is 16℃). If you want to cancel it, set the temp. as 24℃.
So the temp. compensation range is +8℃~-6℃.
21. Anti-freezed protection
When compressor has run for over 5 minutes, to prevent indoor evaporator freezing (in cooling/dry mode),
if indoor mid-coil temp. is below -1 degree for over 5 minutes, indoor EEV will close, and compressor will
stop. When indoor mid-coil temp. is over about 10 degree, the unit will be normal.

1. For the indoor failure,only running LED of remote receiver will indicate.
2. For the outdoor failure,timer LED and running LED will indicate.timer LED of remote receiver stands for ten's place,and running
LED stands for one's place.timer LED will flash firstly,2 seconds later,running LED will flash too. Afer that,4 seconds later,they will
flash in turns again.Flash times equals to the failure code of outdoor plus
20.For example,failure code of outdoor is 2,the indoor unit should display 22.As a result,timer LED flashes twice firstly,then running
LED flashes twice.
3.To get much more details of outdoor unit failure,Please refer to the the outdoor unit trouble shooting list

There are three methods to connection wire controller and the indoor units:
A.One wired controller can control max. up to 16 sets of indoor units, and 3 pieces of polar wire must connect the wire
controller and the master unit (the indoor unit connected with wire controller directly), the others connect with the master
unit through 2 pieces of polar wire.
B. One wire controller controls one indoor unit, and the indoor unit connects with the wire controller through 3 pieces of
polar wire.
C. Two wired controllers control one indoor unit. The wire controller connected with indoor unit is called master one, the
other is called slave one. Master wire controller and indoor unit; master and slave wire controllers are all connected
through 3 pieces of polar wire.
6. Communication wiring:
The wire controller is equipped with special communication wiring in the accessories. 3-core terminal (1-white 2-yellow
3-red) is connected with the terminal A, B, C of wire controller respectively.
