AC System with White Rodgers with Comfort Alert Technology
 
What is the proper way to pump down? :thumbsup:

Scroll compressor isn't suppose to be drawn lower then 20PSIG. But if your going to go to 0, just hold the contactor in.

Condenser with this controller board doesn't have contactor or test bottom to pumpdown. I think I need to jumper LPC to be able to pumpdown to 20PSIG.

The ones I'm use to use a contactor. Of course, I mostly see them on AAONs with digitals scrolls.
