Check the strength and level of the installation ground so that the unit will not cause any operating vibration or noise after installed.
In accordance with the foundation drawing in fix the unit securely by means of the foundation bolts.(Prepare four sets of M8 or M10
foundation bolts, nuts and washers each which are available on the market.)
It is best to screw in the foundation bolts until their length are 20mm from the foundation surface.
Outdoor Unit Installation Guideline
Where a wall or other obstacle is in the path of outdoor unit's intake or exhaust airflow, follow the installation guidelines below.
For any of the below installation pattems, the wall height on the exhaust side should be 1200mm or less.
Limitations on the installation
2.Selecting a location for installation of the indoor units
The maxinum allowable length of refrigerant piping, and the maxmum allowable height difference between the outdoor and indoor units,
are listed below. (The shorter the refrigerant piping, the better the performance. Connect so that the piping is as short as possible. Shortest
allowable length per room is 3m)
1.Precautions on installation
Check the strength and level of the installation ground so that unit will not cause any operating vibration or noise after installation.

Refrigerant piping work
1. Installing outdoor unit
1) When installing the outdoor unit, refer to "Precautions for Selecting the Location" and the "Indoor/Outdoor Unit Installation Drawings".
2)If drain work is necessary, follow the procedures below.
2. Drain work
1) Use drain plug for drainage.
2) If the drain port is covered by a mounting base or floor surface, place additional foot bases of at least 30mm in height under the
outdoor unit's feet.
3) In cold areas, do not use a drain hose with the outdoor unit.(Otherwise, drain water may freeze, impairing heating performance.)

4. Purging air and checking gas leakage
WARNING
3. Refrigerant piping work
When piping work is completed, it is necessary to purge the air and check for gas leakage.
1) Do not mix any substance other than the specified refrigerant (R410A) into the refrigeration cycle.
2) When refrigerant gas leaks occur, ventilate the room as soon and as much as possible.
3) R410A, as well as other refrigerants, should always be recovered and never be released directly into the environment.
4) Use a vacuum pump for R410A exclusively. Using the same vacuum pump for different refrigerents may damage the vacuun pump
or the unit.
If using additional refrigerant, perform air purging from the refrigerant pipes and indoor unit using a vacuum pump, then charge additional
refrigerant.
Use a hexagonal wrench (4mm) to operate the stop valve rod.
All refrigerant pipe joints should be tightened with a torque wrench at the specified tightening torque.
Connect projection side of charging hose(Which comes from gauge manifold) to gas stop valve's service port.
Fully open gauge manifold's low-pressure valve(Lo) and completely close its high-pressure valve(Hi).
(High-pressure valve subsequently requires no operation.)
Apply vacuum pumping. Check that the compound pressure gauge reads-0.1MPa(-76cmHg).
Evacuation for at lease 1 hour is recommended.
Close gauge manifold's low-pressure valve(Lo) and stop vacuum pump.
(Leave as is for 4-5 minutes and make sure the coupling meter needie does not go back.
If it does go back, this may indicate the presence of moisture or leaking from connecting parts. After inspecting all the connection and
loosening then retightening thenuts, reqeat steps 2-4. )
Remove covers from liquid stop valve and gas stop valve.
Turn the liquid stop valve's rod 90 degrees counterclockwise with a hexagonal wrench to open valve.
Close it after 5 seconds, and check for gas leakage.
Using soapy water, check for gas leakage from indoor unit's flare and outdoor unit's flare and valve rods.
After the check is complete, wipe all soapy water off.
Disconnect charging hose from gas stop valve's service port, then fully open liquid and gas stop valves.
(Do not attempt to turn valve rodj beyond its stop.)

7.Precautions for Laying Refrigerant Piping
Cautions on pipe handling
1) Protect the open end of the pipe against dust and moisture.
2) All pipe bends should be as gentle as possible. Use a pipe bender for bending.(Bending radius should be 30 to 40mm or larger.)
Selection of copper and heat insulation materials
When using commercial copper pipes and fittings, observe the following :
1) Insulation material: Polyethylene foam
Heat transfer rate: 0.041 to 0.052W/mK(0.035to 0.045kcal/mh
o
C)
Refrigerant gas pipe's surface temperature reaches 110
o
C max.
Choose heat insulation materials that will withstand this temperature.
2) Be sure to insulate both the gas and liquid piping and to provide insulation dimensions as below.
Check the type of refrigerant to be used on the machine namiplate.
Precautions when adding R410A
Fill from the liquid pipe in liquid form.
It is a mixed refrigerant, so adding it in gas form may cause the refrigerant composition to change, preventing normal operation.
1) Before filling, check whether the cylinder has a siphon attached or not.(It should have something like "liquid filling siphon attached"
displayed on it.)
2) Be sure to use the R410A tools to ensure pressure and to prevent foreign objects entering.
1) This system must use refrigersant R410A.
2) Add refrigerant 20g per meter when the total piping length
exceeds the standard value, but make sure that the total liquid
piping length should be less than the max. value.
1) When using this product, you need not to set the address. But the L/N wires between indoor & outdoor units must be corresponded,
or there will be communication failure.
2) Quiet Operation Setting. Set the DIP "8" to ON position of SW5, the system will run with lower noise, but the max. capacity will also
reduce slightly.
3) Do not change the settings of other switchs, wrong settings can make the system damage or other malfunctions.
Filling a cylinder with an attached siphon
Stand the cylinder upright when filling.
There is a siphon pipe inside, so the
cylinder need not be upside-down
to fill with liquid.
Filling other cylinders
Turn the cylinder upside-down
when filing.

8.Cutting and Flaring work of piping
Pipe cutting is carried out with a pipe cutter and burs must be
removed.
After inserting the flare nut, flaring work is carried out.
WARNING
3) Use separate thermal insulation pipes for gas and liquid refrigerant
pipe.
It becomes high
midway.
The end is immersed
in water
It waves.
Less than
5cm
It gap with the ground its
too small.
There is the bad
smell from a ditch.
Please pour water in the drain pan of the indoor unit, and confirm that drainage is carried out serely to outdoor.
In case that the attached drain hose is in a room, please apply heat insulation to it without fail.
9. On drainage
Please install the drain hose so as to be downward slope without fail. Please don't do the drainage as shown below.
Correct Incorrect
Lean Damage of flare Crack Partial Too outside
1) Do not use mineral oil on flared part.
2) Prevent mineral oil from getting into the system as this would educe the lifetime of the units.
3) Never use piping which has been used for previous installations. Only use parts which are delivered with the unit.
4) Do never install a drier to this R410A unit in order to guarantee its lifetime.
5) The drying material may dissolve and damage the system.
6) Incom;ete flaring may cause refrigerant gas leakage.
Cut exactly at right
angles.
Remove burrs
Flare's inner
surface must be
flaw-free.
The pipe end
must be evenly
flared in a perfect
circle.
Make sure that the
flare nut is fitted.

3.3.5 When discharging temp. Td is too high, modify the EEV angle.
In order to cooperate the compressor discharging temp. over high protection, the system will enlarge the
EEV open angle. Within 5 minutes after compressor starts up, it will not modify. The detecting period is 30
seconds.

3.5 Electric heater control
If compressor has not run for a long time, the refrigerant will deposit on the bottom of compressor and mix
with the refrigeranr oil. When re-startup, because low pressure reduces, refrigerant will be segregated
from the refrigerant oil and cause soam in the oil, which will make compressor exhaust a lot of oil.
Therefore please stop heating the compressor bottom to ensure the low pressure in startup period should

3.6 Control of defrosting in heating
In heating mode, defrosting temp. sensor will check the frosting condition of outdoor heat exchanger and
make defrosting control.
3.6.1 Enter condition:
①In heating mode, if the compressor has run for 10 minutes continously and run for 45 minutes in all, the
system will measure the defrosting temperature sensor Te and outdoor ambient temp. sensor TA, if the
below condition can be met for continous 5 minutes, the unit will enter defrosting operation:
Te≤C×TA－α
Herein: C：TA＜0℃，C=0.8 TA≥0℃，C=0.6
According to SW5-2, the setting is as fo
Jumper
llow: in the place easy to frost, it is H; when out of factory, it is M.

②Defrosting entering condition: -15℃≤C×TA－α≤-2℃
③Stop and Pause condition of compressor running accumulative time in heating mode:
Checking Stop: running operation changes from heating to cooling.
Checking Pause: thermostat OFF, or the unit stops.
3.6.2 Cancel condition:
It will take the max. 10 minutes from beginning defrosting to quit it. Te sensor will measure the condition of
outdoor heat exchanger, if the temp. is over 7℃ for 60 seconds in all or is up to 12℃ for 30 seconds in all,
the defrosting will be over.
3.6.3 Compulsory defrosting control
Enter condition: in heating mode, after receiving the compulsory defrosting signal from indoor unit, the unit
will perform the compulsory defrosting operation.
Cancel condition: Te≥12℃ and keep for 1 minute or the defrosting time is over 10 minutes.
The manual defrosting signal of indoor unit will remain until the outdoor enters defrosting mode.
Note: When outdoor compressor not running, the unti still can enter manual defrosting, but it will comply
with the 3-minute protection of compressor.
Purpose: make compressor frequency control if the discharging temp. is too high, to lower the discharging
temp. efficiently and ensure the system can run normally.

3.7Frequency control when Td is too high
When the input signal of pressure switch is high level:1, that shows there is no protection.
When the input signal of pressure switch is low level: 0 for 1 minute, that shows high pressure protection
works. At this time, compressor stops, outdoor will send the alarm signal. The alarm can be resumable. If
in 60 minutes, the failure occurs 3 times, the failure can be confirmed and send failure code to indoor.
Meanwhile, by controling the max. condensate temp. Tc (cooling) or TmAVE (heating), please confirm as
follow:
In nominal cooling/dry/heating mode, high pressure can be controlled by limiting the max. frequency.
(1) When compressor is running, if output signal of low pressure switch is low level: 0 for 1 minute
continously, compressor will stop,outdoor alarms. The alarm can be resumable. If in 60 minutes, the
failure occurs 3 times, the failure can be confirmed and send failure code to indoor.
(2) When compressor no running, if output signal of low pressure switch is low level: 0 for 30 seconds
continously, alarm will occur.

3.8 Frequency control when there is CT over current protection
3.9 High pressure protection
3.10 Low pressure protection
·When unit stops, the reason that system still checks the low pressure : in a long time stop, make
protection for the compressor on the condition of great refrigerant leakage.
·The reason that low pressure switch action time is 30 seconds: when compressor stops, low pressure
does not change, so it will be shorter than the set time in operation.
(3) When compressor starts up, in 8 minutes, low pressure switch signal will be shielded.
(4) In defrosting, low pressure switch will be shielded.
(5) In oil return procedure, low pressure switch will be shielded.
(6) In the refrigerant discharging procedure after the oil return in cooling is over, low pressure switch will
be shielded.
In addition, the system will control low pressure through the evaporator temp. TE to realize the low
pressure protection function.
In cooling, confirm through Tc2AVE:
In heating, confirm through defrosting temp. Te:
If the failure is not confirmed as the permanent protection, outdoor will not send failure code to indoor, and
indoor will not alarm.

When the compressor running frequency is lower than 58Hz (E) continuously for 8 hrs, 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 the compressor restarts up, the time will be counted
continuously. In a continuous 8 hrs, if the compressor running frequency is not less than 72Hz for
over 10 minutes continuously, the accumulative time will be cleared. Also after the heating
defrosting, the time will be cleared.
Cooling mode: refer to “the oil return procedure in cooling mode”
Heating mode: refer to “the oil return procedure in heating mode”
In the course of oil return, because of protection or abnormal unit stop, after the unit restarts up, the
time will not be cleared, the system will need another oil return operation. In the refrigerant flow
course in the oil return of cooling mode or after the oil return, and within 5 minutes after the
refrigerant being eliminated is over, the anti-freezed protection is invalid, and also the low voltage
protection is invalid. But the other protection is valid.
In the course of oil return from heating mode to cooling mode, if abnormal condition occurs or the
unit stops for protection, then the system needs not another oil return within 3 minutes after the unit
stops and it will start up directly, then to heating mode.
In the course of oil return from heating mode to cooling mode, the anti-freezed protection is null and
void, and the low voltage protection is null either. The other protection is valid.

>_]]VbTZR\ <Zb >_^UZdZ_^Vb
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℃.
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.

Trouble 9: AC current over current protection or current transducer damaged, or compressor blocked
rotor, compressor great vibration, compressor abnormal startup, state detecting curcuit abnormal or
compressor damaged.
The former twice failure can be resumed automatically, if outdoor board occurs this failure always, and
can not be resumed for a long time, that shows:
1. Power module (SPDU) damaged, please replace the power module, then re-wiring as per the wiring
diagram (70% possibility)
2. Short circuit in power board results in the power module damaged (15％ possibility)
3. Damaged compressor results in this failure (10％ possibility)
4. Main control board is faulty, replace it (5％ possibility)
Trouble 10: High pressure failure
Reasons:
1. Over high system pressure results that the unit stop, and the compressor protection will work. The
failure can be resumed.
2. Pressure switch wire is not fixed well or in open circuit.
