1.Connect the recharged hose to lower pressure valve jucntion ( low/high pressure valve must be
tightened.)
2.Connect the charged hose junction with vacuum pump.
3.Open the low pressure handler of manifold fully.
4.Start vacuumizing with vacuum pump. Wjhen vacuumizing begins,loosen the nut of low pressure
valve a bit. Check is the air enters(noise of vacuum pump changes, the all-purpose meter indication
changefrom negative to zero), then tighten the nut of connection pipe.
5.After vacuumizing finishing, tighten thelow pressure
handler of manifoldvalve fully and stops the vacuum pump.
When vacuumizing is carried out for over 15 minutes,
please confirm if the all-purpose meter points at -1.0X10
