The Sure Bail 470017 float switch is a reliable device commonly used in water level management systems, such as sump pumps, sewage systems, and water tanks.

Proper wiring and installation are essential for its efficient operation. Below is a step-by-step guide to understanding its wiring diagram and setup.

Key Components and Wiring Basics

1. Components Needed:
   • Sure Bail 470017 float switch
   • Power source (110V or 220V depending on setup)
   • Pump or load device
   • Wire connectors and electrical tape
   • Wire stripper and screwdrivers
2. Wiring Diagram Overview:
   • Common (COM) Wire: Connects to the power source.
   • Normally Open (NO) Wire: Activates the pump when the float rises.
   • Normally Closed (NC) Wire: Optionally used for reverse operations, such as turning off a device when the float rises.

Step-by-Step Wiring Instructions

1. Turn Off Power: Ensure the power supply is disconnected to prevent electrical hazards.
2. Prepare Wires: Use a wire stripper to expose the necessary lengths of wire.
3. Connect the Wires:
   • Attach the COM wire to the power source.
   • Connect the NO wire to the pump’s power input.
   • Insulate unused wires, such as the NC wire, if not required.
4. Secure Connections: Use wire connectors and electrical tape to prevent exposed connections.
5. Mount the Float Switch: Position the float switch inside the tank or reservoir, ensuring it can move freely without obstructions.

Testing and Maintenance

1. Test the Setup: Reconnect power and observe the float switch operation as the water level changes. The pump should activate and deactivate appropriately.
2. Regular Maintenance: Inspect the float and connections periodically for wear, debris, or corrosion. Keep the system clean to ensure reliable operation.

Common Troubleshooting Tips

• If the pump doesn’t activate:
  • Check all wire connections and ensure they are secure.
  • Verify that the float can move freely without obstructions.
• If cycling occurs too frequently:
  • Ensure the water level and pump settings are correctly aligned.
• Replace frayed or damaged wires immediately to maintain safety.
