from the liquid side stop valve. The Lo-knob should be closed completely.
③
Turn off the R410A tank and the Hi-knob immediately, when the adding refrigerant is
enough.
④
Turn on the liquid and gas side stop valves in an anticlockwise direction slowly and completely.
2) If the pressure of the system is too high to charge refrigerant, you can do as follow.
①
Turn on the liquid and gas side stop valves in an anticlockwise direction slowly and completely.
