Crucial points:
When testing, never use oxygen,flamable and poisonous gases.
Step 1:Charge for more than 3 minutes under 0.3MPa(3.0kg/cm2g)
Step 2:Charge for more than 3 minutes under 1.5MPa(15kg/cm2g)
--Serious leakage may be found.
Step 3:Charge for more than 24 hours under 3.0MPa(3.0kg/cm2g)
--Small leakage may be found.
Check for pressure decrease
Without pressure decrease-Pass
With pressure decrease-Check for leaage.There will be a 0.01MPa(0.1kg/cm2g) pressure change
for every 1 C ambient temperature change during the 24-hour pressure charge.It should be
corrected during the test.

Check for leakage

In the case of pressure decrease during steps 1 to 3 ,check the joints with the ear,hand or soapsuds for
leakage.Repair it by welding or tighten the connecting nut up.
Vacuum Pumping
Use vacuum pump to evacuate the air.Never use the refrigerant for the evacuation.
Drain off the nitrogen gas after the leak test and then connect the vacuum pump as shown in the figure
below.
The vacuum pumping must be done from both the liquid and gas inlets.

installation installation
Use a vacuum pump with high degree of vacuum(below-755mmHg) and large volume displacement
(above 40L/min)
The pumping time depends on the length of the connecting pipe.Generally,it takes about 2-3 hours.
Make sure that the Y-shaped valves on both the gas and liquid sides are closed before pumping.
If the vacuum can no reach-755mmHg within 2 hours,continue pumping for another 1 hour.
If the vacuum can no reach-755mmHg after more than 2 hour's pumping,close the valves VL and
VH on the gauge distributor and stop pumping.One hour later,check the vacuum again.If the
vacuum has changed,it means there is a leakage.Repair it.
After the above steps,replace the vacuum pump with the refrigerant pump and refill refrigerant.
Charging refrigerant

Refilling of refrigerant
After the vacuum pumping,replace the vacuum pump with the refrigerant pump and refill refrigerant.
Calculation of refrigerant quantity
The factory filled refrigerant into the piping excludes the part of pipes according to be refilled on the site.
Refill the amount of refrigerant into the piping according to the following formula.
The factory filled refrigerant is listed in the table below:
The quantity of the refrigerant to be refilled during installation depends on the diameter and length
of the liquid piping.
The quantity of the refrigerant t be refilled on the site=Actual length of liquid tube x quantity of
refrigerant to be refilled for per meter of liquid pipe.
Recharge refrigerant
When the outdoor valve is shut,fill the refrigerant from the access hole at the gas and liquid sides.
If the required filling is impossible,open all the gas and liquid valves,then slightly shut the gas
valve, run the compressor and fill the refrigerant from the access hole at the gas side.Now adjust
the gas valve to control the refrigerant flow,which will be gasified during absorption by the system.
If there is insufficient refrigerant in the system caused by leaks,refill it after the remaining refrigerant
is recollected.
Open all valves
Open all the valves of the outdoor unit.
Heat isolation of the pipes
Separate isolation should be made for the liquid and gas pipes.
Materials used for the pipe isolation at the gas side must withstand above 120 C temperature.
For AU96NATAEA:
Charging refrigerant (R22): Before charging refrigerant, the pressure in the system
must be kept at least for 15 minutes under 130Pa, and the pressure will not go up
within 30 minutes, only in this case, the refrigerant can be filled.
When the connection pipe is less than 5 meters, additional refrigerant needs not be
charged. Once the connection jpipe is more than 5 meters, please recharge the
refrigerant as the following formula:
Refrigerant quantity=(lenth of connection pipe-5m)*115g
Detailed procedures:
a.Cut off the vacuum pump pipe to prepare charging refrigerant
b.Place the R22 container on the scales, switch off the low pressre valve of the
pressure pipe to make the liquid type refrigerant enter the system from the high
pressure side.
c.If the system pressure goes up, stop charging refrigerant and when the
refrigerant quantity arrives the rated value, switch off the high pressure valve,
then place the R22 container on the scales with the jaw to up. Open the low pressure
valve to start up the unit, at this time, the refrigerant is gas state.
When the charged refrigerant arrives the rated value, after confirming the refrigerant
quantity is proper, unload the flexible joint and install the copper nut of the connector.

3.Calculation of refrigerant density
Calculation will be made according to the following methods:
1) Total refrigerant content of each system (kg) =content of 1 outdoor system + refilled refrigerant
Content of 1 outdoor system:Factory filled refrigerant
Refilled refrigerant:Filled content during installation according to the diameter and length of the
liquid piping.
2) Calculation of the minimum room sapce (m3).
3) Calculation of refrigerant density
Total refrigerant content Refrigerant density:0.3(kg/m3)
Minimum room space
22

2.Preventive measures against excess of critical value

1) Make ventilation holes
Ventilation holes should be built above and under the door.The area of each hole should not be
smaller than 0.15% of the room space.Holes can be made directly in the wall.
2) Reduce the filling content of refrigerant
Filling content of refrigerant can be reduced by shortening the distance between the indoor and
outdoor units.
By reducing the capacity of the outdoor unit.
When outdoor unit be made up of several units.the outdoor capacity of each system should
reduce.Sothe refrigerant content of system reduce.
3) Install ventilation fans.
Users can install uninterrupted ventilation fans to keep the refrigerant density under the critical
value.
If uninterrupted ventilation is impossible,a combined fanning and alarming device should be
installed in its stead (through which immediate ventilation is possible when leak occurs).

(f) Avoid putting the outlet of drain hose in the places with irritant gas generated. Do not insert the drain hose directly into
drainage,where the gas with sulfur may be generated.
(g) Backwater bend
Because the drain spout is at the position, which negative pressure may occur. So with the rise of water level in the
drain pan, water leakage may occur. In order to prevent water leakage, we designed a backwater bend.
The structure of backwater bend should be able to be cleaned. As the below figure shown, use T type joint.The backwater
bend is set near the air conditioner.
As figure shown, set a backwater bend in the middle of drain hose.

8. 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

9. The examples of improper installation

Do not use air in duct and take the ceiling inner side 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.
Air discharging fan

34 Improper example

10. The operation method of fan controller
Through the fan controller switch in the electric box, the air volume of this unit can be continuously adjusted.
It is unnecessary to adjust air volume through the duct side wind level (unit outside static adjustment).
The air volume set should be in the operation air volume range.
Figure I shows the position of fan controller in the electric box and operation method.
After finishing the electric work, perform test run. According to the main points in Figure II making the chosen switch No.
accordant. And confirm if it reaches the needed air volume.
Note:
1) When operating the fan controller, it is possible to touch the electric charging part, so do cut off the power supply.
2) Do not set the dial at the position less than 1.
3) The figure circled in Figure II indicate the capacity number of fan controller. The non-listed capacity number may exceed
the permitted operation capacity range, so it is impossible to operate.
4) When delivering from factory, the capacity number of fan controller is set at No.5.

9. Electrical Control Functions

Anti-freezed protection：
After running for 9 minutes from compressor startup, the unit will check if the indoor coil
temperature is below 0℃, the outdoor fan motor will stop running.
After the compressor stops, if the below conditions can be met, the compressor and the outdoor fan
motor will begin to run again:
1.Shutoff time over 3 minutes
2.Indoor coil temperature up to over 7℃
3-minute protection of compressor when startup
Once the compressor stops running, you can restart up only after 3 minutes. When the unit
powered off in operation, if the shutoff time is below 3 minutes, it will be 3 minutes at least after
powered on when the compressor starts up again. Powered on for the first time, there is no
3-minutes delay protection.
Auto defrosting function
1) Starting condition
The unit is in heat mode, and the compressor runs for 35 minutes continuously.
The compressor has run totally for 45 minutes, and the compressor runs for over 5 minutes
continuously.
If either of the above conditions is met, and the indoor receives the defrosting signal from the
outdoor unit, the unit begins to defrost and send the signal to outdoor.
2) Quit condition
The outdoor receives the signal to quit from the defrost or the defrosting time is over 12 minutes,
the defrost will be over and send the relative signal to the outdoor.
Temperature cutoff protection：
When the indoor coil temperature is over 68℃ for 10 seconds, the compressor and the outdoor fan
motor will stop. When the compressor has stopped for 3 minutes and when the coil temperature is
below 46℃, the compressor and the outdoor fan motor will operate again.
Anti cold air protection in heat mode：
If it is the first time in heat mode or the defrost is over, when the indoor coil temperature is below 28
59

℃, the indoor fan motor will stop when the indoor coil temperature is no less than 28℃ and less
than 38℃, the indoor fan motor will run in low speed when the indoor coil temperature is over 38℃
or the compressor has run for over 4 minutes, the indoor fan motor will run at the set speed.
