System charging
Has anyone had problems with charging a system with liquid in the low side of a domestic refrigerator using 134A? I have always been taught and have also read that there is a risk of compressor damage by doing this.

Hi Dylan

Re: System charging
There is a small device called KWIK CHARGE that you connect to the suction line and charge with liquid refrigerant.
Never used it, only saw it. I believe it made by Imperial of USA.

Re: System charging
As good practice I always take my time when filling with liquid.
On the comps I have opened the intake is at the top inside the body and probebly not much chance of completly filling the body with liquid.
I thought it was that when even a smallish amount of liquid is put in, in boils off and lifts the oil into the pump which can destroy it and not the actual refrigerant liquid.
Exspeicially when youve already evacuated the system and the oil is ready to absorb most of the charge before it warms up.
ps any chance of getting a spell checker on this page. cos mine is atrotiousIF AT FIRST YOU DON`T SUCCEED.
DESTROY ALL EVIDENCE THAT YOU TRIED!
and go get a cuppa

Re: System charging
Use a drier that has a schreader valve fitted ,then charge directly into the liquid line.(NRS)
