how do you charge 404a into an ice machine. so do i turn the cylinder upside down and charge through the low side? the 404a cylinder says charge as a liquid only and do not connect to hi side.
so i can only charge through the low side? do i need to get a special valve that flashes the liquid into gas or is that already built into the cylinder. or can i slowly add liquid through the low side with the system turned on? what is the best and easiest way to charge the system?
