Turn on the high-pressure valve on the manifold pressure gauge and inject the refrigerant to the system from high-pressure pipeline.
At this time, the attention shall be given to the readings of high-pressure meter and low-pressure meter, and make sure that these two
pressure all go up. If the refrigerant is being injected while the pressure does not go up, then the joints of the pipeline may be loosened
or the seals damaged, inject the refrigerant once more after finding out the cause and the fixing. When the increase of pressure stops,
turn off the high-pressure valve of the manifold pressure gauge and then start the engine
.
Operate the switch in a way as follows:
Turn the switch of air conditioner to “ON”
Regulate the temperature controller to the coolest position,
Enable the air conveying to the maximum,
Select the internal air circulation between the internal/external air circulation,
During this process, the door and windows will be all opened.
Adjust the engine’s speed to the specified free running speed.
Erect the refrigerant reservoir or gas bottle (have the refrigerant injected into the refrigerating system in a gas state), turn on the
low-pressure valve of the manifold pressure gauge.
When the compressor is at work, please do not turn on the high-pressure valve.
Before checking the refrigeration level, please confirm the injection volume of the refrigerant specified for air conditioning system.
When injecting the refrigerant, carefully observe the high-pressure side of the manifold pressure gauge and the flow condition of
the refrigerant (clear, foaming or turbid), all these could be viewed through the inspection window, by which the moment of stop
injecting the refrigerant can be reasonably judged(turning off the low-pressure valve).

When judging the injection volume of the refrigerant, please make the settings based on the following working conditions:
Water tank temperature of the engine: stable
Speed of the engine: normal free running speed
Switch of air conditioner: ON
Switch of the fan: “High” gear
Temperature controller: air return temperature inside the car is between 25

Daily Maintenance of Air Conditioning System
In order to ensure normal operation of air conditioning system, maintenance and care services shall be frequently performed for the
air conditioning system. The daily maintenance of air conditioning system is illustrated as follows:
1. Inspect, wash and clean the condenser of air conditioning system, requiring that radiator pins are clean and there is no dirt
between the pins. After the car runs in the rain or on the muddy road, the fan of the condenser should be inspected to find
whether it bears the earth, sand, stone and etc, and remove them if any.
2. Check the quantity of the working media of the refrigerating system; when the compressor set works normally, observe the
liquid viewing glass, under the normal circumstance, there shall be not air bubbles in the glass.
3. Inspect the drive belt. The belt between the compressor and the engine should be tensioned.
4. Check if there is any abnormal noise or odor in the air conditioning system.
5. Check if the temperature difference between the air inlet and outlet of the compressor is normal.
6. Check if the hose of the refrigerating system is in an apparent good condition and connections of all joints are secure.
7. Check if the pipeline of the refrigerating system collides with other parts and components, and if there is any oil leakage trace
left at each joint.
8. Check if the circuit connection of the refrigerating system is secure and if there is an occurrence of short circuit and falling off
9. Check if fastening bolts of the compressor are firmly secured or broken. d. When connecting the pipe, apply little compressor oil to the O-ring and fasten the nut with two wrenches. Attention: never
spatter the compressor oil to the painted parts or the plastic components to avoid the corrosion. If these components are
spattered with the oil, please clean it immediately.
e. When connecting the pipe, please follow the torque listed in the following table to fasten the screws or the nuts:
Diameter of Pipe Fastening Torque (N·m)
￠8mm 12-15
￠16mm 30-35 30－35


At ends of each pipe the protective caps should be installed till the pipe is connected to the refrigerating system.
