Pumping Down/Recovering Refrigerant

Postby vvmt501 » Sat Jun 16, 2012 5:15 pm

I'm a maintenance tech at an apartment complex in Las Vegas. Summer is upon us, and numerous A/C units are malfunctioning due to leaks, thermal overloads, etc. I am seeking time saving ways to complete A/C repairs. I understand there is a way to pump down/move refrigerant from the coils directly into the compressor without recovering them into the pressurized cans first. How is this done?

Running in AC mode shut down the high side valve at the "King Valve" at the outdoor service port, when you're PSI pumps down to 0 PSI shut the low side valve then cut off or kill power to outdoor unit. Just remember when done to pull VAC before you open the valves to let the freon go back into the lines and evap. No it does not matter what valve you open first -)
