Hey TC, how does the automatic drain work from HF? It looks like it is set to go off at 145 lbs. So if your compressor's high limit is set to 150 it will never shut down, and if it is set at 140 the auto-drain will never trip. I don't get it.
The auto drain we had at work had an electrical solinoid wired into the switch that opened it for a few seconds whenever the compressor shut down.
