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.
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.
Check for leakage
Vacuum Pumping
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 V
L
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.
