The evacuation of air from the air conditioning system

If the refrigerant circuit was opened and it was in the air, it must be pumped out using a vacuum pump. After installing the air conditioning system is to be pumped for 15 minutes. Node, which opened for repair and maintenance must be evacuated within 30 minutes.

PERFORMANCE ORDER

The engine should be switched off.
Connect the inlet tube pressure gauges to the compressor and close the valves of high and low pressure.
Make sure that the refrigerant has been removed from the air conditioning system.
Connect the central hose pressure gauges to the input of the vacuum pump.
Run the vacuum pump and open the valves of high and low pressure.
After 10 minutes, the vacuum must be equal to 94.39 kPa. If desired underpressure is not reached, the air conditioning system has a leak which must be eliminated in the following manner :.

Close both valves and stop the vacuum pump ;.
Charge air conditioning in about 0.4 kg of refrigerant;
Check the tightness of the air conditioning system. Repair any leaks found;
Re discharge the air conditioning system and evacuate it. If leaks are found, continue to pump out system.

Run the vacuum pump.

Open both the discharge valve until the vacuum 94.39 kPa.
After a low pressure manometer shows a vacuum which is close to 94.39 kPa continue pumping 15 minutes.

After evacuation for 15 minutes, close the product valves and stop the vacuum pump. Disconnect the hose from the vacuum pump. The system is now charged.
