Working principle and special functions for cooling
Air conditioner absorbs heat in the room and transmit to outdoor and discharged,
so that indoor ambient temperature decreased, its cooling capacity will increase
or decrease by outdoor ambient temperature.
Anti-freezing function
If the unit is running in COOL mode and in low termperature, there will be frost formed
on the heat exchanger, when indoor heat exchanger temperature decreased below 0
the indoor unit microcomputer will stop compressor running and protect the unit.
Working principle and special functions for heating
* Air conditioner absorbs heat in the room and transmit to outdoor and discharged,
will increase, its heating capacity will decrease by outdoor ambient temperature.
so that indoor ambient temperature increased, so room heating capacity.
* If outdoor temperature got lower, please operate with the other heating ventilating
* When outdoor temperature is low but high humidity, after a long while running,
frost will form on outdoor unit, that will effect the heating effect, at this time,
the auto defrosting function will act, the heat running will stop for 8-10mins.
* During the auto defrosting, the fan motors of indoor unit and outdoor unit will stop.
* During the defrosting, the indoor indicator flashes, the outdoor unit may emit vapor.
This is due to the defrosting, it isn't malfunction.
* After defrosting finished,the heating will recover automatically.
Anti-freezing function:
In "HEAT" mode, if in the following status, the indoor heat exchanger haven't achieve
the certain temperature, that the indoor unit will not act, in order to prevent cool air blowing.
(Within 3mins)
1.Heating starts. 2.After Auto defrosting finished. 3.Heating under the low temperature.

piping can be lead out from right, right rear,
left, left rear.
routing the piping and wiring from the left
or right side of indoor unit, cut off the tailings
from the chassis in necessary (show in Fig.2)
(1).Cut off the tailings 1 when routing the wiring only;
(2).Cut off the tailings 1 and tailings 2 when routing
both the wiring and piping.(or 1,2,3);
2.Take out the piping from body case, wrap the piping
electric wire, water pipe with tape and put them through the piping hole (As show in Fig. 3)

3.Hang the mounting slots of the indoor unit on the
upper tabs of the rear panel and check if it is firm
enough. (As show in Fig.4)
Install the connection pipe
1.Align the center of the piping flare with the relevant valve.
2.Screw in the flare nut by hand and then tighten
the nut with spanner and torque wrench refer
to the following.

NOTE: Firstly connect the connection pipe to indoor unit, then to outdoor unit; pay attention
to the piping bending, do not damage the connection pipe; the joint nut couldn't tighten too
much, otherwise it may cause leakage.
Install outdoor unit
Electric Wiring
1. Disassemble handle of right side plate or front side plate of outdoor unit.
2. Take off wire clamp, connect and fix power connect cord to terminal of line bank.
Wiring should fit that of indoor unit.
3. Fix the power connection cable with wire clamp, for cooling and heating unit, then use the
wire clamp to fix the signal control wire, then connect the corresponding connector.
4. Ensure if wire has been fixed well.
5. Install handle or front side plate.
Wrong wiring may cause spare parts malfunction.
After the cable fixed, make sure there should be a free space between the connection and
fixing place on the lead wire.
Air purging and leakage test
● Air purging and leakage test
1. Connect charging hose of manifold valve to charge end of low
pressure valve (both high/low pressure valves must be tightly
2. Connect joint of charging hose to vacuum pump.
3. Fully open handle handle of Lo manifold valve.
4. Open the vacuum pump to evacuate. At the beginning, slightly
loosen joint nut of low pressure valve to check if there
is air coming inside.
5. After finishing evacuation, shut Lo handle of manifold
valve to stop the vacuum pump. (Keep evacuating for
more than 15 minutes and make sure the reading of
multi-meter is -1.0 10 5pa(-76cmHg)
6. Fully open high/low pressure valves.
7. Remove charging hose from charging end of low
pressure valve.
8. Tighten bonnet of low-pressure valve. (As shown in Fig.5)

● Leak hunting
Indoor unit check point
Use soap water or leak hunting meter to check whether
the joints is leak.
Indoor unit check point
Outdoor condensation drainage (Heat pump type only)
When the unit is heating, the condensing water
and defrosting water can be drained out reliably
through the drain hose.
Installation: Install the outdoor drain elbow in
Ø 25 hole on the base plate, and joint the
drain hose to the elbow, so that the wastewater
formed in the outdoor unit can be drained out
to a proper place.

Check after installation
Items to be checked
Possible malfunction
Has it been fixed firmly?
The unit may drop, shake or emit noise.
Have you done the refrigerant leakage test?
It may cause insufficient cooling(heating)
Is heat insulation sufficient?
It may cause condensation and dripping.
Is water drainage well?
It may cause condensation and dripping.
Is the voltage in accordance with the rated
voltage marked on the nameplate?
It may cause electric malfunction
or damage the part..
Is the electric wiring and piping
connection installed correctly and securely?
It may cause electric malfunction
or damage the part.
Has the unit been connected to a secure
earth connection?
It may cause electrical leakage.
Is the power cord specified?
It may cause electric malfunction
or damage the part
Is the inlet and outlet been covered?
It may cause insufficient cooling(heating)
Has the length of connection pipes
and refrigerant capacity been recorded?
The refrigerant capacity is not accurate.
Test Operation
1. Before test operation
(1) Do not switch on power before installation isfinished completely.
(2) Electric wiring must be connected correctly and securely.
(3) Cut-off valves of the connection pipes should be opened.
(4) All the impurities such as scraps and thrums must be cleared from the unit.
2. Test operation method
(1) Switch on power, press "ON/OFF" button on the wireless remote control to start the
(2) Press MODE button, to select the COOL, HEAT, FAN to check whether the operation
is normal or not.
This unit contains fluorinated gases with greenhouse effect covered by the Kyoto Protocol.
Maintenance and disposal must be carried out by qualified persons only.
Refrigerant gas R410A, GWP = 1730
Pursuant to Regulation EC 842/2006 on certain fluorinated greenhouse gases, in case of extra
refrigerant charge, it is compulsory to:
Fill in the label accompanying the unit inserting the factory quantity of refrigerant
charge (see the technical label), the extra refrigerant charge and the total charge.
Apply the label next to the technical label applied on the unit. For the split-type air
conditioner apply on the outdoor unit.
