Setup and Installation
The SEAFLO Electric Field Bilge Pump Switch is designed for user-friendly installation. Ensure all power is disconnected before beginning installation.
Mounting the Switch
The switch can be mounted using its base or the integrated mounting ears. Position the switch in the lowest part of the bilge where water collects, ensuring the sensor pads are clear of obstructions.

Wiring Diagram
Connect the switch according to the following diagram. The switch requires a 12V or 24V DC power source. Ensure all connections are secure and properly insulated to prevent corrosion and short circuits.
- Connect the positive (+) wire from the battery to the switch.
- Connect the other wire from the switch to the positive (+) terminal of your bilge pump.
- Connect the negative (-) wire from the bilge pump directly to the negative (-) terminal of the battery.

Operating Instructions
The SEAFLO Solid State Electric Field Bilge Pump Switch operates automatically based on water levels detected by its integrated sensors. It features intelligent water level detection and false start prevention.
Automatic Operation
- The pump activates automatically when the water level reaches 41mm (1.6 inches) at the higher sensor.
- The pump deactivates when the water level drops to 9.5mm (0.37 inches) at the lower sensor.
- A built-in three-second delay prevents unnecessary activation caused by water sloshing in the bilge, ensuring precise operation.

Testing the Switch
To test the functionality of the switch after installation or periodically:
- After installation, hold your fingers for 10 seconds on the two raised circles (sensor pads) on the switch face.
- If wiring is correct, the pump will activate.
- Remove your top finger; the pump should stay on.
- Remove your bottom finger; the pump should turn off after a short delay.
- Alternatively, test with water in the bilge to confirm that the pump turns on and off properly. If not, reposition the switch to allow for proper activation and deactivation levels.

Maintenance
The SEAFLO Solid State Electric Field Bilge Pump Switch is designed for minimal maintenance due to its robust construction and lack of moving parts.
- Regular Inspection: Periodically inspect the switch and its wiring for any signs of damage, corrosion, or debris accumulation.
- Cleaning: If debris or residue accumulates on the sensor pads, gently wipe them clean with a damp cloth. Ensure the pads are free from oil, grease, or silicone, as these can affect sensor performance.
- Corrosion Resistance: The fully sealed electronics and absence of exposed sensors make the switch highly resistant to corrosion in both saltwater and freshwater environments.
Troubleshooting
If you encounter issues with your SEAFLO Bilge Pump Switch, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not activate when water level is high. |
|
|
| Pump does not turn off when water level is low. |
|
|
| Pump activates too frequently (false starts). |
