Completely tighten the flare nuts, A, B, C, D, connect the manifold valve
charge hose to a charge port of low-pressure valve on the gas pipe side.
ii.
Connect the charged hose connection to the vacuum pump.
iii.
Fully open the handle "Lo" of the manifold valve.

Operate the vacuum pump to evacuate. After starting the evacuation,
slightly loosen the flare nut of the "Lo" valve on the gas pipe side and
check that the air is entering. (Operation noise of the vacuum pump
changes and a compound meter indicated 0 instead of minus)

After the evacuation is complete, fully loosen the handle "Lo" of the
manifold valve and stop the operation of the vacuum pump.
Make evacuation for 15 minutes or more and check that the compound
meter indicates -76cmHg(-1.0x10 Pa).

Turn the stem of the packed valve B about 45
seconds after the gas comes out, then tighten the flare nut again. Make
sure the pressure display in the pressure indicator is a little higher than
the atmosphere pressure.
