5. Setup and Installation
Proper installation is crucial for the pump's performance and safety. Follow these steps:
- Mounting: Select a suitable location in the lowest part of the bilge where water collects. Secure the pump firmly to a flat surface using appropriate fasteners. The removable strainer base allows for easy mounting and detachment of the motor cartridge.
- Hose Connection: Connect a 1-1/8" (29 mm) ID hose to the pump's outlet. Ensure the hose is routed upwards to a through-hull fitting above the waterline, with a continuous upward slope to prevent airlocks. Use marine-grade hose clamps to secure the connection.
- Wiring: This is a manual bilge pump and requires an external switch or float switch for operation. Connect the pump's positive (brown) wire to the positive terminal of your 12V DC power source via a 5A fuse and a control switch (manual or automatic float switch). Connect the negative (black) wire to the negative terminal of your power source. Ensure all connections are watertight using marine-grade connectors and heat shrink tubing.

6. Operating Instructions
The SEAFLO 01 Series 1100 GPH Bilge Pump is a manual pump, meaning it requires an external switch to activate. It does not have an integrated float switch.
- Manual Operation: To operate the pump manually, activate the connected manual switch. The pump will run as long as the switch is engaged.
- Automatic Operation (with external float switch): If an external float switch is installed, the pump will activate automatically when the water level rises and lifts the float switch. It will turn off once the water level drops below the switch's activation point.
- Testing: Periodically test the pump by introducing water into the bilge or by manually activating the switch to ensure it operates correctly.

7. Maintenance
Regular maintenance ensures optimal performance and extends the life of your bilge pump:
- Strainer Cleaning: Periodically inspect and clean the strainer base to remove debris such as leaves, hair, or other foreign objects that can impede pump operation. The snap-off design allows for easy removal and cleaning.
- Impeller Inspection: After removing the strainer, inspect the impeller for any damage or blockages. Ensure it spins freely.
- Electrical Connections: Check all electrical connections for corrosion or loose wiring. Clean and re-seal as necessary to maintain watertight integrity.
- Hose Inspection: Ensure the discharge hose is free of kinks, blockages, or leaks.

8. Troubleshooting
If your SEAFLO bilge pump is not operating as expected, refer to the following common issues and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not run | No power, blown fuse, loose wiring, faulty switch. | Check power supply, replace fuse, inspect and secure wiring, test switch. |
| Pump runs but no water is discharged | Clogged strainer/impeller, airlock, collapsed hose, pump not submerged. | Clean strainer/impeller, clear airlock by tilting pump or cycling power, check hose for obstructions, ensure pump is fully submerged. |
| Low flow rate | Partially clogged strainer/impeller, low voltage, excessive head. | Clean strainer/impeller, check battery voltage, ensure discharge hose is clear and routing is optimal. |
| Pump runs continuously (with float switch) | Stuck float switch, faulty float switch, wiring error. | Inspect float switch for obstructions, test float switch, verify wiring connections. |
