INTRODUCTION
The Auto Drain system consists of a 12 volt normally open solenoid, a filter and assorted fit-
tings. Designed to work with the Auto Pump 12V, the solenoid bleeds the filter bowl when the
pump is not running. As soon as the pressure switch turns on the compressor, the solenoid
is energized and the bleed is closed. A check valve is installed on the Auto Drain assembly
to seal off the vehicle’s air pressure when the bleed valve opens.
