Re: charging r407c by weight
Well, refrigerant in the bottle is in liquid state.
In the mean time i repare 3 units, when the charging stops, before whole amount was charged into unit i turn on unit. Then compressor work decrease the suction pressure and make it possible to charge with the amount from rating label.
Is it correct method of charging?
