INTRODUCTION
The Auto Drain system consists of a 12 volt normally open solenoid, a filter and assorted
fittings. Designed to work with the 12 volt Auto Pump, 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 that is supplied with the
Auto Drain kit must be installed as shown to seal off the vehicles air pressure when the
bleed valve opens.
