Hey guys, I just started working on "high end" refrigerators, and w/ R134a. Ive worked with 2 guys so far and they both handle the recovery and charging differently. One guy uses the "sweep charge" method, always changes the drier and then weighs the charge back in.
The other guy recovers the R134a through his manifold gauges and then uses a vacuum pump on the system. Then he charges through his manifold gauges until the low side is around 2 psi and the high side is around 125 psi.
2 completely diff. styles! I want to figure out what style is right, the best, the fastest, and in general which way will work best for me? Anyone have any opinions?
