1) When the liquid and gas stop valves have not been opened, the system is under the
vacuum:
①
Refer to the left of the Fig. 20, connect the R410A tank to the system.
②
Turn on the R410A tank and the Hi-knob, charge the R410A refrigerant into the system
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.
②
Turn on the power of the air conditioner, and set cooling mode, running more than 0.5h when
outside temperature is higher than 15
°C
