● Use vacuum pump
1. Connect the charging hose of manifold valve to charging
port of low-pressure valve. Both high-pressure valve and
low-pressure valve must be tighten up).
2. Connect joint of charging hose to vacuum pump.
3. Fully open Lo （low pressure ） handle of manifold valve
and start the vacuum pump for vacuum pumping.
4. Usually the vacuum pumping time of 2600W AC is about
15min. The vacuum pumping time of 5000W AC is about
20min. The vacuum pumping time of 7200W AC is about
30min. Make sure the pressure is -1.0X105pa (-76cmHg).
When vacuum pumping is finished, close Lo （low pressure）
handle of manifold valve completely to stop the vacuum pump.
(Note: R410A refrigerant special vacuum pump should be
applied for R410A unit.)
