Questions and Answers

How do I check the operation of the low pressure switch and light? If I unplug the connector on the low pressure switch should the light come on in the cab?
View Staff Answer 
Good question! We checked with the engineers at PureFlow AirDog. This is what they said: "Unplug the AirDog with the Key in the “On” position with the engine off and it should illuminate the low pressure light on the dash. When the AirDog is plugged back in, the light should go off." Try this out and let us know if you have any issues.
