1. Connect charging hose of manifold valve to charge end of low pressure
valve (both high/low pressure valves must be tightly shut).
2. Connect joint of charging hose to vacuum pump.
3. Fully open the handle of Lo manifold valve.
4. Open the vacuum pump for vacuumization. At the beginning,
slightly loosen joint nut of low pressure valve to check
if there is air coming inside. (If noise of vacuum pump
has been changed, the reading of multimeter is 0) Then
tighten the nut.
5. Keep vacuuming for more than 15mins and make
sure the reading of multi-meter is
(-76cmHg) . .
6. Fully open high/low pressure valves.
7. Remove charging hose from charging end of low pressure valve.
