Operation Testing

1. Plug the pump's power cord into the control panel outlet cable.
2. Test the high-oil circuit
• Lift the float switch with the sump empty of water.
• Oil is non-conductive, and when the float is lifted only the HIGH OIL indicator will be illuminated.
• The auxiliary contacts in the control panel and the remote alarm will activate.
3. Test a pump cycle.
• Make sure the discharge plumbing is directed correctly.
• Slowly fill the tank with water until the water reaches the START
probe.
• Make sure the pump turns on and operates until the water level
falls below the OFF probe.
• Check the discharge plumbing for leaks.
4. Test the high-water circuit.
• Unplug the pump from the control panel.

probe.
• Make sure the HIGH WATER indicator illuminates.
• Verify the auxiliary contacts in the control panel activate the remote alarm.
