vaccuming of domestic refrigerator
Hello! I wanted to ask any professional here about vacuum timings a household refrigerator requires before being charged with refrigerant.
I have checked pressure drop in refrigerator when vaccuming and it drops to near zero in about 7-10 mins however i was told that vaccuming must be done atleast 20 mins.
