The flow switch is a critical component to the 75094 Inline Manifold system . When water flow has stopped,
to prevent damage to the cell or system, it is important power to the SuperCell be automatically turned
OFF. The water flow switch performs this function.
In order to test that this component is working properly:
1. Turn off circulation pump.
2. Confirm that the AG system is still receiving power. (Some AG systems will be installed to turn
off when the water pump is off). Please follow all safety codes when routing power to the unit.
DO NOT use an extension cord to provide power to the unit.
3. Verify that the red “Check System” light is flashing. The AG system will also display “no Flo” in
a scrolling message. This means it has no water flow. If the check system light does not turn on,
please verify that the flow switch jumper is NOT installed, then have the unit serviced.
4. Turn on the water pump. The red “Check System” light should turn off showing the unit has water
flow.
5. Turn off water pump and route power back to normal.
