Wit most modern refrigerants being charged in the liquid state care must be taken not to flood the compressor with liquid.

It is best to charge into the liquid side as the liquid charge can be added quite quickly and therefore the majority of the charge can be added. The remaining charge can then be added carefully via the suction side with the unit running.

Dear Brian ,

Thank for your reply.
But based on my trial, both of method (charge through low pressure or high pressure) , i still found unstable High Voltage test, Especially after store at warehouse for 1 dan 2 days, the ampere value was increasing. i use R-32 for refrigerant.

Are you have experienced about that ?

Thank You
