SEAFLO Bilge Pump Control Switch User Manual

1. Product Overview

The SEAFLO Bilge Pump Control Switch is a marine-grade panel designed to provide reliable control over your bilge pump system. It offers three operational positions: Automatic (AUTO), Off (OFF), and Manual (MAN), allowing for flexible management of water levels in your vessel. This waterproof switch panel is built for durability in marine environments and includes an LED indicator for operational status and protection against intermittent high current. It is suitable for yachts, RVs, and other marine applications.

3.2 Installation Steps

1. Choose Mounting Location: Select a flat, accessible surface on your marine vessel or RV for mounting the switch panel. Ensure it is protected from direct water spray if not explicitly rated for submersion.
2. Cut Mounting Hole: Use the provided dimensions (refer to Figures 2, 3, or 4 for your specific model) to cut an appropriate opening for the switch panel.
3. Connect Wiring:
   • Connect the positive (+) wire from your battery to the input terminal of the overload protector (if applicable) and then to the switch's power input.
   • Connect the manual (MAN) output from the switch directly to the positive (+) terminal of the bilge pump.
   • Connect the automatic (AUTO) output from the switch to the positive (+) terminal of the float switch. The other terminal of the float switch should then connect to the positive (+) terminal of the bilge pump.
   • Connect the negative (-) wire from the bilge pump and the float switch (if applicable) directly to the negative (-) terminal of your battery or a common ground point.
   • Ensure all connections are secure and properly insulated using marine-grade connectors (e.g., heat shrink butt connectors) to prevent corrosion and short circuits.
4. Mount the Panel: Secure the switch panel into the cutout using the provided screws.
5. Test Functionality: Reconnect power and test all switch positions (AUTO, OFF, MAN) to ensure the bilge pump operates correctly.

Note: Some models may include a built-in fuse or require an external fuse. Always ensure proper fusing for your bilge pump circuit to protect against overcurrent.

4. Operation

The SEAFLO Bilge Pump Control Switch provides intuitive control over your bilge pump. The LED indicator illuminates when the pump is actively running.

4.1 3-Position Switch (AUTO-OFF-MAN)

• AUTO (Automatic) Position: In this position, the bilge pump will operate automatically, activated by a connected float switch. When the water level rises and triggers the float switch, the pump will turn on. Once the water level drops and the float switch deactivates, the pump will turn off.
• OFF Position: This position completely deactivates the bilge pump. The pump will not run, regardless of the float switch position or manual input.
• MAN (Manual) Position: In this position, the bilge pump will run continuously, bypassing the float switch. Use this for manual dewatering or testing. Remember to switch back to AUTO or OFF when manual operation is no longer needed to prevent battery drain or pump damage.

4.2 2-Position Switch (OFF-ON)

• OFF Position: The bilge pump is completely deactivated.
• ON Position: The bilge pump will run continuously. This type of switch is typically used in conjunction with an external float switch and a separate manual override switch, or for simple manual operation.

5. Maintenance

Regular maintenance ensures the longevity and reliable operation of your bilge pump control switch.

• Inspect Wiring: Periodically check all wiring connections for corrosion, fraying, or loose terminals. Ensure connections are tight and insulated.
• Clean Panel: Wipe down the switch panel with a damp cloth to remove salt, dirt, and grime. Avoid abrasive cleaners or solvents that could damage the panel finish or markings.
• Test Functionality: Regularly test the switch in all positions (AUTO, OFF, MAN) to confirm proper operation. For AUTO mode, manually lift the float switch to ensure the pump activates.
• Check for Water Ingress: Although waterproof, inspect the panel for any signs of water ingress, especially around mounting screws or cable entries. Ensure seals are intact.

6. Troubleshooting

If your bilge pump system is not functioning as expected, follow these troubleshooting steps:

• Pump Does Not Run in MAN/ON Position:
  • Check battery voltage.
  • Inspect all wiring connections for looseness or corrosion.
  • Check the fuse or circuit breaker for the bilge pump circuit. Replace if blown.
  • Verify the bilge pump itself is operational by connecting it directly to a 12V/24V power source (briefly).
• Pump Does Not Run in AUTO Position (but runs in MAN/ON):
  • Check the float switch. Manually lift the float to see if the pump activates.
  • Inspect wiring between the switch, float switch, and pump for any breaks or loose connections.
  • Ensure the float switch is clean and free from debris that might impede its movement.
• Pump Runs Continuously in AUTO Position:
  • Check the float switch. It might be stuck in the "up" (activated) position due to debris or mechanical failure.
  • Inspect wiring for a short circuit that might be continuously activating the pump.
• LED Indicator Not Working:
  • Verify the pump is actually running when the LED should be on.
  • Check for loose connections to the LED.
  • The LED itself might be faulty (though rare).

7. User Tips

• Regular Testing: Always perform regular functional tests of your bilge pump system, especially before and after each use of your vessel, to ensure it is ready for emergencies.
• Proper Sealing: When installing, ensure all cable entries and mounting points are properly sealed with marine sealant to maintain the waterproof integrity of the panel and prevent water intrusion into your electrical system.
• Battery Management: In manual mode, the pump runs continuously. Be mindful of your battery's charge level to avoid draining it completely.
• Overload Protection: The switch is designed to prevent impact from intermittent high current. However, always ensure your bilge pump circuit has appropriate fusing or an overload protector installed as per marine electrical standards.
