5. Installation
Please follow these instructions carefully to ensure proper and safe installation of your SFSP-01 switch panel. Improper installation can lead to damage not covered by warranty.
5.1 General Considerations
- Mounting Position: The switch panel may be mounted in any position. Ensure the mounting surface is rigid to avoid transmitting noise and vibration.
- Securing: Secure the panel firmly, but do not overtighten the screws, as this can reduce their ability to dissipate noise and vibration.
- Accessibility: Install the switch in an easily accessible location.
- Circuit Protection: The electrical circuit for the pump should be protected with an over-current protection device (fuse). This switch panel typically requires an 8 amp fuse.
- Dedicated Circuit: The pump should be wired on its own dedicated circuit and should not include any other electrical loads.
- Voltage Check: After installation, check the voltage at the pump motor when the pump is operating. Full voltage must be available at the pump motor at all times.
5.2 Electrical Wiring
Connect the positive lead (red wire) from the switch panel to the positive terminal of your battery. Connect the negative wire (black wire) from the switch panel to the negative terminal of your battery. Ensure all connections are secure and properly insulated, especially in a marine environment.
The following table provides guidance on appropriate wire sizing based on distance:
| Distance (Ft. / M) | AWG (MM²) |
|---|---|
| 0-50 (0-15) | 16 AWG |
| 50-65 (15-19) | 14 AWG |
| 65-100 (19-30) | 12 AWG |
| 100-130 (30-39) | 10 AWG |

6. Operating Instructions
The SFSP-01 switch panel features a three-position toggle switch to control your bilge pump:
- MAN (Manual): In this position, the pump will run continuously, regardless of the float switch position. Use this for manual emptying of the bilge.
- OFF: In this position, the pump is completely off and will not operate.
- AUTO (Automatic): In this position, the pump's operation is controlled by the connected float switch. The pump will turn on automatically when the water level rises and activate the float switch, and turn off when the water level drops.
Turn the pump off when not used for extended periods or when the tank is empty to prevent dry running.
7. Maintenance
While the switch panel itself requires minimal maintenance, regular checks of the overall bilge pump system are crucial for reliable operation:
- System Cleanliness: Regularly check and clean the plumbing lines and pump intake for debris accumulation.
- Float Switch Inspection: Periodically inspect the float switch for proper movement and ensure it is free from obstructions.
- Electrical Connections: Ensure all wiring connections remain tight and free from corrosion.
- General System Check: Perform routine checks of the pump and associated components as per the pump manufacturer's guidelines.
For specific maintenance procedures related to the bilge pump itself, please refer to the pump's dedicated instruction manual.
8. Troubleshooting
This section addresses common issues that may arise with your bilge pump system, which can often be related to the switch panel or its connections.
8.1 Pulsating Flow - Pump Cycles On and Off
- Check lines for kinks.
- Plumbing lines or fittings may be too small.
- Clean faucets and filters.
- Check fitting tightness for air leaks.
8.2 Failure to Prime but Motor Operates - No Pump Discharge
- Restricted intake or discharge line.
- Air leak in intake line.
- Punctured pump diaphragm (pump issue).
- Initial amp supply is not enough to sufficiently start the motor.
- Debris clogged in the valves (pump issue).
- Crack in pump housing (pump issue).
8.3 Motor Fails to Turn On
- Loose or improper wiring (check switch panel connections).
- Pump circuit has no power.
- Blown fuse (check fuse connected to switch panel).
- Failed pressure switch (pump issue).
- Defective motor (pump issue).
8.4 Pump Fails to Turn Off After All Fixtures Are Closed
- Punctured diaphragm (pump issue).
- Discharge line leak.
- Defective pressure switch (pump issue).
- Insufficient voltage.
- Clogged valves in pump head (pump issue).
9. User Tips
- Secure Connections: Always ensure all electrical connections are tight, properly crimped, and sealed, especially in a damp marine environment, to prevent corrosion and ensure reliable operation.
- Float Switch Testing: Periodically test your float switch by manually raising it to ensure the pump activates and deactivates correctly in AUTO mode.
- Fuse Protection: Never replace a blown fuse with one of a higher amperage. Always use the recommended 8 amp fuse to protect your wiring and pump.
