1. Air purging with vacuum pump
1) Completely tighten the flare nuts of the indoor and outdoor units, confirm that both the 2-way and 3-way
valves are set to the closed position.
2) Connect the charge hose with the push pin of handle lo to the 3-way valves gas service port..
3) Connect the charge hose of handle hi connection to the vacuum pump.
4) Fully open the handle Lo of the manifold valve.
5) Operate the vacuum pump to evacuate.
6) Make evacuation for 30 minutes and check whether the compound meter indicates -0.1Mpa. If
the meter does not indicate -0.1Mpa after pumping 30 minutes, it should be pumped 20 minutes more. If the
pressure
can‘t achieve -0.1Mpa after pumping 50 minutes, please check if there are some leakage points.
Fully close the handle Lo valve of the manifold valve and stop the operation of the vacuum pump. Confirm
that the gauge needle does not move (approximately 5 minutes after turning off the vacuum pump).
7) Turn the flare nut of the 3-way valves about 45° counterclockwise for 6 or 7seconds after the gas coming
out, and then tighten the flare nut again. Make sure the pressure display in the pressure indicator is a
little higher than the atmosphere pressure. Then remove the charge hose from the 3 way valve.
8) Fully open the 2 way valve and 3 way valves and securely tighten the cap of the 3 way valve.
