Safety Precautions
WARNING
Have the unit professionally installed.
Improper installation by an unqualified person may result
in water leak, electric shock, or fire.
Place the unit on a stable, level surface that withstands the
weight of the unit to prevent the unit from tipping over or
falling causing injury as a result.
Only use specified cables for wiring. Securely connect each
cable, and make sure that the cables are not straining the
terminals.
Cables not connected securely and properly may generate
heat and cause fire.
Be sure to carefully follow each step in this handbook when
installing the unit.
Improper installation may result in water leak, electric shock,
smoke or fire.
Have all electrical work performed by a licensed electrician
according to the local regulations and the instructions given
in this manual. Secure a circuit designated exclusively to
the unit.
Improper installation or a lack of circuit capacity may cause
the unit to malfunction or present a risk of electric shock,
smoke,and fire.
Take necessary safety measures against typhoons and
earthquakes to prevent the unit from falling over.
Securely attach the terminal cover(panel) on the unit.
If installed improperly, dust and/or water may enter the unit
and present a risk of electric shock, smoke or fire.
Do not make any changes or modifications to the unit. In
case of problems, consult the dealer.

and present a risk of electric shock, or it may produce smoke
or cause fire.
Only use refrigerant R410A as indicated on the unit when
installing or relocating the unit.
The use of any other refrigerant or an introduction of air into
the unit circuit may cause the unit to run an abnormal cycle
and abnormal cycle and cause the unit to burst.
WARNING
Do not touch the fins on the heat exchanger with bare hands,
for they are sharp and dangerous.
In the event of a refrigerant gas leak, provide adequate
ventilation to the room.
If leaked refrigerant gas is exposed to a heat source, noxious
gases may form.
With All-Fresh type air conditioners, outdoor air may be
directly blown into the room upon thermo off. Take this into
consideration when installing the unit.
Direct exposure to outdoor air may present a health hazard,
and it may also cause food items to deteriorate.

leakage.
NO
NO
Halide torch

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.

to identify the leaking point. After confirming the leaking point, welding it again or tighten the nut tightly again.
Installation Procedure
Additional Refrigerant Charge
When the total length (L) of the two indoor units' connecting pipe is less than 5m, it is unnecessary to charge additional
refrigerant.
If the connecting pipe (L) exceeds 5m, it shall charge M(g) additional refrigerant per meter.
That is: Refrigerant charging amount = (L-5m) x 45 (g/m)
Only in COOLING operation can charge the additional refrigerant.
When charging, the refrigerant shall be charged from the charging nozzle of low pressure valve.
Be carefull when charging refrigerant, do not let the air mix into the system, and must charge the additional refrigerant
in liquid state.

Selecting the mounting position to install the indoor units
Select suitable places where the outlet air can be sent to the entire room, and convenient to lay out
the connection pipe, connection wire and the drainage pipe to outdoor.
The ceiling structure must be strong enough to support the unit weight.
The connecting pipe, drain pipe and connection wire shall be able to go though the building wall
to connect between the indoor and outdoor units.
The connecting pipe between the indoor and outdoor units as well as the drain pipe shall be as
short as possible.
If it is necessary to adjust the filling amount of the refrigerant, please refer to the installation manual
attached with the outdoor unit.
The connecting flange should be provided by the user himself.
The indoor unit has two water outlets one of which is obstructed at the factory (with a rubber cap). Only the outlet not obstructed
(liquid inlet and outlet side) will be generally used during installation. If applicable, both the outlets should be used together.
An access port must be provided during installation of indoor unit for maintenance.
After selecting the unit installation location, proceed the following steps:
1. Drill a hole in the wall and insert the connecting pipe and wire through a PVC wall-through tube
purchased locally. The wall hole shall be with a outward down slope of at least 1/100.
2. Before drilling check that there is no pipe or reinforcing bar just behind the drilling position.
Drilling shall avoid at positions with electric wire or pipe.
3. Mount the unit on a strong and horizontal building roof. If the base is not firm, it will cause noise,
vibration or leakage.
4. Support the unit firmly.
5. Change the form of the connection pipe, connection wire and drain pipe so that they can go through the wall hole easily.

The length difference among every duct is limited below 2:1.
Reduce the length of duct as possible as can.
Reduce the amount of bend as possible as can.
Use heat insulation material to bind and seal the part connecting main
unit and the flare part of air discharging duct. Perform duct installation
work, before the fitment of ceiling.

Installation Procedure
Air Duct
The attentive matters in installation of air suction and discharging duct
Recommend to use anti-frost and sound-absorbing duct. (locally bought)
The duct installation work should be finished before the fitment of ceiling.
The duct must be heat insulated.
The specific air-discharging outlet should be installed at the place where the
airflow can be reasonably distributed.
The surface should leave a checking meatus for checking and maintenance.
Special air discharging outlet
Use screw bolt to fix
Duct
Air
The examples of improper installation
Do not use air inlet duct and take the ceiling inner side as duct instead.
The result is because of the irregular outer air mass, strong wind and
sunshine, the humidity is increased.
There may be water drop on the outside of duct. For cement and other
new constructions, even if not taking ceiling inner side as duct, the
humidity will also be so high. At this time, use glass fiber to perform
heat preservation to the whole. (use iron net to bind the glass fiber)
Maybe exceeding the unit operation limit (for example: when indoor
dry bulb temperature is 35 C, wet bulb temperature 24 C), it may lead
to overload of compressor.
Affected by the capacity of air discharging fan, the strong wind in the
outer duct and wind direction, when unit air sending volume exceeds
the limit, the discharged water of heat exchanger will overflow, leading
to water leakage.

Installation Procedure
Refrigerant Pipe
The gas side pipe, liquid side pipe must be faithfully heat insulated, if no heat insulation, it may cause water leakage.
The outdoor unit has been charged with refrigerant.
When connect the pipe to the unit or dismantling the pipe from the unit, please follow the figure shown, use spanner and
torque spanner together.
When connect cone nut, the inner side and outside of cone nut should paste with refrigerant oil. Use hand to twist 3-4
rings, then fasten with spanner.
Referring to Table I to confirm the fasten torque. Too tight may damage nut leading to leakage.
Check if the connection pipe leaks, then do heat insulation treatment, as below figure shown.
Only use seal cushion to bind the joint part of air pipe and heat insulation parts.

3.8 Oil return operation control
3.8.1 Entering condition
When the compressor running frequency is lower than 58Hz continuously in all and outdoor
unit Tcm is lower than 50 degree for 5 hours, the system will enter oil return operation. In the
course of mode changeover, manual unit stop or protective unit stop, the time will be
accumulative. After compressor restarts up, the time will counted continuously. In counting
time for 5 hour, if the compressor running frequency is over 80Hz for 10 minutes continuously,
the time will be cleared. Also after the heating defrosting , the time will be cleared.
108
3.8.2 Procedure
Cooling mode: refer to “the oil return procedure in cooling mode”
Heating mode: refer to “the oil return procedure in heating mode”
3.8.3 The protection treatment in oil return operation:
In the course of cooling oil return, because of all kinds of protection or abnormal unit stop,
after the unit restart, the time will not be cleared, the system need another oil return operation.
In the refrigerant flow course in oil return of cooling mode or after oil return, and within 5
minutes after the refrigerant being eliminated is over, the anti-freeze protection and low
pressure protection are invalid, other protection is valid.
In the course of heating oil return ,because of all kinds of protection or abnormal unit stop, the
system need not another oil return operation after the unit stop for 3 minutes and enter in
heating mode directly. In the course of changing to cooling oil return, the anti-freeze
protection and low pressure protection are invalid, other protection is valid.

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.
22. Overload protection in heating mode
It is valid only in heating mode, if indoor mid-coil temp. is over about 65 degree continuously for 10
seconds, indoor will stop; while when indoor mid-coil temp. is below 52 degree for 3 seconds, indoor will
resume.

2. Install the controller holder
According to the position of 2 screw holes on the
holder, drill 2 holes on the wall, and strike the wood
stopper to the holes respectively.
Then align the 2 screw holes of wired controller
holder to the wood stopper, fix the holder on the wall
with wood screw.
Note:Try a wall as flat as possible for installation.
Don't use excessive force to tighten screws,
otherwise, the holder will be damaged.
3.Wiring instruction
Use shielded wire between indoor and wire controller.And be earthed on one side, or the unit will not work normally
because of interference.
Note:Confirm the terminal connection firmly, and do not get in tough with shielded wire.
4.Place wire controller on the holder, and pay attention not to pressing any wires.

Wire controller
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(3 pieces for model AD*SS1ERA, and the bridge CN22 CN23 on slave units PCB
should be cut off).
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.
The communication wiring is 5 meter long; if the actual length is more than it, please distribute wiring according to below
table:
