POST INSTALLATION TESTING OF YOUR POWERHALT SHUT-OFF VALVE
Once the installation is complete, ensuring that all the steps, schematics and recommendations have been
followed, it is time to test your system.
1. Activate the manual switch (no engine running).
NOTE: DO NOT ACTIVATE THE MANUAL SWITCH FOR MORE THAN 10 SECONDS.
Damage to the solenoid may occur
2. View valve and confirm valve has tripped. The reset knob should be in the tripped position
This will have the line direction on the reset knob, perpendicular from the air flow direction.
3. Reset the valve.
4. Activate both pull cable stations.
5. Reset valve.
6. Start the engine and run.
7. Activate the PowerHalt shut-off valve by pushing the test button on the PowerGuard Controller for
at least 3 seconds. The engine should stop within a few seconds.
• If the engine does not shutdown in the specified time please check all intake piping and hoses
for leaks between the valve and intake system.
• If the system is leak-free and your valve still does not shutdown the engine, please consult a
PowerHalt Service Representative for support.
8. Once the engine stops, wait 30 seconds, then reset the valve by turning the red reset knob
clockwise to the open “Run” position with knob line in line with the air flow direction.
