5. Installation and Setup

Proper installation is crucial for optimal pump performance and longevity. This pump is self-priming up to 5 feet (1.5 m) suction lift.

5.1 Mounting

• Mount the pump in a dry, well-ventilated area.
• Utilize the integrated rubber feet to minimize vibration and noise during operation.
• Ensure the pump is mounted securely to a stable surface.

5.2 Plumbing Connections

• The pump features 5/8" quick attach ports for easy connection.
• Standard fittings and filters are included for convenience.
• Ensure all connections are tight and leak-free. Use thread sealant if necessary.
• Install a filter on the inlet side to prevent debris from entering the pump.

5.3 Electrical Wiring

• Connect the pump to a 12V DC power source.
• Ensure correct polarity: Red wire to positive (+), Black wire to negative (-).
• Install an appropriate fuse in the positive power line to protect the pump and electrical system.
• Refer to the detailed wiring diagram for complex system integrations, such as marine plumbing systems.

6. Operation

The SEAFLO 23 Series pump operates automatically based on demand, controlled by its integrated pressure switch. When a faucet or outlet is opened, the pressure drops, and the pump activates. When the outlet is closed, the pressure rises, and the pump shuts off.

• Initial Start-up: After installation, open a faucet to allow air to purge from the system and the pump to prime. The pump will begin to move water once primed.
• Automatic Operation: The pump will cycle on and off as water is demanded and supplied.
• Manual Control: If equipped with a manual switch, use it to turn the pump on or off as needed.

7. Maintenance

Regular maintenance ensures the longevity and efficient operation of your SEAFLO pump.

• Inspect Connections: Periodically check all plumbing and electrical connections for leaks, corrosion, or loose wiring. Tighten as necessary.
• Clean Filters: If an inline filter is installed, clean it regularly to prevent blockages and maintain optimal flow.
• Winterization: In freezing climates, ensure the pump and plumbing system are completely drained or protected with non-toxic antifreeze to prevent damage.
• General Cleaning: Keep the exterior of the pump clean and free from dirt and debris.

8. Troubleshooting

If you encounter issues with your pump, refer to the following basic troubleshooting steps:

• Pump Not Running: Check power supply, fuse, and electrical connections. Ensure the pressure switch is functioning correctly.
• Low Flow or No Flow: Check for clogged filters, kinks in hoses, or air in the system. Ensure the water source is adequate.
• Pump Cycles Rapidly: This may indicate a leak in the system, a faulty pressure switch, or an accumulator tank issue (if installed). Check all connections for leaks.
• Unusual Noise: Inspect for loose mounting, debris in the pump head, or air in the system.

9. User Tips

• For applications requiring consistent pressure, consider installing an accumulator tank in your system.
• Always ensure the pump is easily accessible for inspection and maintenance.
• When using for food-grade applications, ensure all connected components are also food-grade certified.
• The pump's IP54 rating means it is protected against splashing water, but it is not designed for submersion.
