5. Installation and Setup
Proper installation is crucial for the pump's performance and safety.
5.1 Mounting
- Select a suitable location in the lowest part of the bilge where water collects. The pump must be mounted vertically on a flat surface.
- The pump features a removable strainer base for easy mounting. Detach the motor cartridge from the base by pressing the release tabs.
- Secure the strainer base to the bilge floor using appropriate marine-grade fasteners (not included). Ensure the base is firmly attached to prevent movement during operation.
- Once the base is secured, reattach the motor cartridge by aligning it with the base and pressing down until it locks into place.

5.2 Plumbing
- Connect a 1-1/8 inch (29 mm) bilge hose to the pump's outlet port. Use a marine-grade hose clamp to secure the connection tightly.
- Route the bilge hose to a suitable thru-hull fitting above the waterline. Ensure the hose has a continuous upward slope to prevent airlocks and backflow.
- Avoid sharp bends or kinks in the hose, which can restrict flow and reduce pump efficiency.

5.3 Electrical Wiring
- The pump is designed for 24V DC systems. Connect the brown wire to the positive (+) 24V DC power source and the black wire to the negative (-) ground.
- Install an in-line 3 Amp fuse in the positive (+) wire, as close to the power source as possible. This protects the pump and electrical system from overcurrent.
- All electrical connections must be made using marine-grade, heat-shrink butt connectors or similar waterproof terminals to prevent corrosion and ensure a secure connection.
- Ensure all wiring is properly routed and secured to prevent chafing or damage.

6. Operating Instructions
The SEAFLO 1100 GPH Bilge Pump is a submersible pump designed for continuous or intermittent duty. It operates when power is supplied to it.
- Manual Operation: If connected to a manual switch, activate the switch to turn the pump on. Turn the switch off when the bilge is clear of water.
- Automatic Operation (with optional float switch): If an external float switch (not included) is installed and wired correctly, the pump will automatically activate when water levels rise and deactivate when water is removed. Refer to the float switch's instruction manual for wiring details.
The pump's moisture-tight seals and marine-grade blocked wiring ensure silent, vibrationless operation and complete submergibility. The anti-airlock protection and backflow prevention check valve work to keep bilges dry and odor-free.

7. Maintenance
Regular maintenance ensures optimal performance and extends the life of your bilge pump.
- Inspect Regularly: Periodically check the pump, wiring, and hose connections for any signs of wear, corrosion, or damage.
- Clean Strainer Base: The removable strainer base should be cleaned regularly to prevent debris from clogging the intake. To clean, disconnect power, detach the motor cartridge from the base, remove any accumulated debris, and rinse thoroughly. Reassemble once clean.
- Check for Leaks: Ensure all hose clamps are tight and there are no leaks in the plumbing system.
- Test Operation: Periodically test the pump's operation by allowing water to accumulate in the bilge or by manually adding water to ensure it activates and pumps effectively.
8. Troubleshooting
If your SEAFLO bilge pump is not operating as expected, refer to the following troubleshooting guide:
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not run | No power to pump | Check fuse, battery connections, and wiring. Ensure switch is in 'ON' position. |
| Motor seized or damaged | Disconnect power and inspect impeller for obstructions. If motor is seized, replacement may be necessary. | |
| Pump runs but no water is discharged or flow is low | Clogged intake strainer | Disconnect power, remove strainer base, and clean thoroughly. |
| Hose kinked or obstructed | Inspect discharge hose for kinks or blockages. Clear any obstructions. | |
| Airlock in pump or hose | Ensure pump is fully submerged. Check hose routing for continuous upward slope. Briefly lift and lower the pump to dislodge air. | |
| Pump runs continuously | Water still present in bilge | This is normal if water is present. |
| Faulty float switch (if installed) | Inspect float switch for debris or malfunction. Replace if necessary. | |
| Backflow through discharge hose | Ensure discharge hose exits above the waterline and has a proper loop or check valve to prevent backflow. |
