2. Safety Information
Read and understand all safety instructions before installing, operating, or performing maintenance on this pump. Failure to follow these instructions could result in serious injury or property damage.
General Safety Precautions:
- Electrical Safety: Always disconnect power before servicing the pump. Ensure the pump is properly grounded. Do not operate the pump with a damaged cord or plug.
- Installation: Installation must comply with all local electrical and plumbing codes. Use appropriate personal protective equipment (PPE) during installation.
- Hazardous Locations: Do not install or use this pump in locations classified as hazardous by the National Electrical Code (NEC), ANSI/NFPA 70.
- Water Temperature: Do not pump liquids hotter than 104°F (40°C).
- Intended Use: This pump is designed for sewage and effluent only. Do not use it for flammable or corrosive liquids.
3. Setup and Installation
Proper installation is crucial for the efficient and safe operation of your sewage pump. Consult a qualified plumber or electrician if you are unsure about any steps.
Installation Steps:
- Basin Preparation: Ensure the sewage basin is clean and free of debris. The pump requires a basin at least 24 inches in diameter for proper float switch operation.
- Pump Placement: Place the pump on a solid, level surface at the bottom of the basin. Ensure it is stable and will not tip over.
- Discharge Piping: Connect the pump's 2-inch discharge to appropriate piping. Install a check valve above the pump to prevent backflow and a shutoff valve for servicing.
- Ventilation: Ensure the basin is properly vented according to local codes.
- Float Switch Adjustment: Position the wide-angle float switch to ensure adequate ON/OFF levels, preventing short cycling and allowing sufficient liquid accumulation.
- Electrical Connection: Connect the pump to a dedicated, properly grounded 115V AC circuit with appropriate overcurrent protection. The 20-foot power cord provides flexibility.
- Testing: After installation, fill the basin with water to test the pump's operation and float switch activation.

4. Operating Instructions
The ECO-FLO ESE50W sewage pump operates automatically via its wide-angle float switch. Once properly installed and connected to power, the pump will activate when the liquid level in the basin rises to a predetermined point and deactivate when the level drops.
Automatic Operation:
- Ensure the float switch is free to move and not obstructed by the basin walls or other components.
- The pump will turn on when the float switch rises to the 'ON' position.
- The pump will continue to operate until the liquid level drops, causing the float switch to fall to the 'OFF' position.
- Monitor the pump's operation periodically to ensure it is cycling correctly.
5. Maintenance
Regular maintenance helps ensure the longevity and reliable performance of your sewage pump. Always disconnect power before performing any maintenance.
Maintenance Schedule:
- Quarterly Inspection: Visually inspect the pump, float switch, and power cord for any signs of wear, damage, or obstruction.
- Basin Cleaning: Periodically clean the sewage basin to remove any accumulated sludge or debris that could interfere with pump or float switch operation.
- Impeller Check: If the pump's performance decreases, inspect the impeller for clogs or damage. (Refer to a qualified technician for internal component inspection).
- Float Switch Test: Manually lift and lower the float switch to ensure it activates and deactivates the pump smoothly.

6. Troubleshooting
Before attempting any repairs, always disconnect the pump from the power source. If you cannot resolve an issue, contact a qualified technician.
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not start or run. | No power; tripped circuit breaker; faulty float switch; motor overload. | Check power supply and circuit breaker. Inspect float switch for obstruction or damage. Allow motor to cool if overloaded. |
| Pump runs but does not pump water. | Clogged impeller; air lock; discharge pipe obstruction; check valve stuck closed. | Disconnect power, clear impeller. Vent air from discharge line. Check discharge piping for blockages. Inspect check valve. |
| Pump cycles too frequently. | Float switch set incorrectly; backflow from discharge line; leaky plumbing. | Adjust float switch settings. Inspect check valve for proper function. Check for leaks in plumbing system. |
| Pump is noisy or vibrates excessively. | Debris in impeller; worn bearings; pump not seated properly. | Disconnect power, clear impeller. Ensure pump is stable on basin floor. Contact technician for worn bearings. |
