the duty cycle of the 12 volt Auto Pump to 1 hour running and 1 hour
Reduces Auto Pump Heating Extends Pump Life Completely Automatic Easy Installation
The Auto Pump Timer limits the duty cycle of the 12 volt
Auto Pump to 1 hour running and 1 hour "OFF". Normally the pressure
switch on the Auto Pump turns the pump "ON" when it senses a low
pressure and turns the pump "OFF" when the pressure has recovered. If a
failure in the vehicle's air system creates a high leakage, the pump
will run continuously. This continuous running can overheat the pump
and cause excessive wear. The Auto Pump Timer limits the run time to 1
hour and provides a 1-hour cool-down period between operating cycles.
The timer does not interfere with the normal operation of the pump and
its pressure switch.
