3. Test the Pressure Switch before putting the SPILLSTOP into operation.
a. Connect an air line to the Regulator and adjust the Regulator to a minimum of 40 psi (2.7 bar). If the SPILLSTOP is installed
with a Whistle and/or more than two Shutoff Valves, increase pressure to a minimum of 60 psi (4.1 bar).
b. Activate the SPILLSTOP by pushing the Float up or raise the Float by turning the SPILLSTOP upside down. Air should start
flowing through the tube connected to Port 3 of the Actuator Valve and the Pressure Switch should power on the electrical
device.
Troubleshooting
If either the pump or the SPILLSTOP do not operate normally after installation, maintenance or service, follow the steps below in the
order shown to source and fix the problem.
1. The SPILLSTOP requires a constant and separate source of compressed air to function properly. With the pump in operation and
air supplied to the SPILLSTOP, adjust the Regulator and verify the gauge reads 40 psi (2.7 bar) or higher.
2. Disconnect all air supply to the pump and SPILLSTOP. Connect an air line to the Regulator and disconnect the plastic tube at
Port 2 of the Actuator Valve. Adjust the Regulator to a minimum of 40 psi (2.7 bar). Air should be flowing from Port 2.
a. If air is not flowing from Port 2, the Actuator Valve may be clogged or damaged and should be cleaned or replaced.
b. If air is flowing from Port 2, check the tubing to the Pump Shutoff Valve to ensure air can flow from the Actuator Valve to the
Shutoff Valve during normal operation.
3. Disconnect the air line to the Regulator. Uninstall the SPILLSTOP completely from the pump and system, and restart the pump.
a. If the pump does not operate normally after removing the SPILLSTOP, refer to the pump manual or contact the pump
manufacturer for instructions to repair the pump.
4. Disconnect all air supply to the pump and reinstall the exhaust hose from the pump's air discharge port (exhaust) to the
SPILLSTOP Inlet connection port. Do not connect SPILLSTOP Shutoff Valve(s).
a. Check that pump exhaust is entering the SPILLSTOP through the Inlet connection port and exiting through the Test Port Plug.
b. Start the pump to ensure the pump operates normally.
5. Disconnect all air supply to the pump and SPILLSTOP. Remove the SPILLSTOP lid and flush internal areas with water or cleaner
appropriate for the process fluid being pumped.
a. Connect an air line to the Regulator and disconnect the plastic tube at Port 2 of the Actuator Valve. Adjust the Regulator to a
minimum of 40 psi (2.7 bar). Air should be flowing from Port 2.
b. Activate the SPILLSTOP by pushing the Float up or raise the Float by turning the SPILLSTOP upside down. Air should stop
flowing from Port 2.
c. If air does not stop flowing from Port 2 when the SPILLSTOP is activated, the Actuator Valve may be clogged or damaged and
should be cleaned or replaced.
6. Reassemble the SPILLSTOP and reconnect Shutoff Valve(s). Adjust the Regulator to a minimum of 40 psi (2.7 bar) to restart the
pump.
a. If the SPILLSTOP is installed with a Whistle and/or more than two Shutoff Valves, increase pressure to a minimum of 60 psi (4.1
bar).
7. Ensure SPILLSTOP Shutoff Valve(s) open when the system is operating.
a. To visually inspect a valve, it is possible to see the piston lift approximately 0.25" from its seat when viewed through Port B.
b. To mechanically inspect a valve, connect a fitting to Port A and supply compressed air to that fitting. If air escapes Port B, the
valve is open.
8. Disconnect all air supply to the pump and SPILLSTOP and reinstall the Pump Shutoff Valve. Verify that compressed air is supplied
to Port A and that the pump's air inlet is connected to Port B. Reapply compressed air to the SPILLSTOP to start the pump. If the
pump does not operate normally, the valve may be undersized for the application. Contact Blacoh for assistance.
9. If using an Exhaust Shutoff Valve, disconnect all air supply to the pump and SPILLSTOP and reinstall the valve. Verify that the
pump's exhaust is connected to Port A and the SPILLSTOP is connected to Port B. Reapply compressed air to the SPILLSTOP
to start the pump. If the pump is not operating normally, the valve may be undersized for the application. Contact Blacoh for
assistance.
