4. Setup and Installation
Proper installation is crucial for the longevity and performance of your submersible motor. Consult a qualified well contractor for installation.
- Pre-Installation Check: Inspect the motor for any shipping damage. Verify that the motor's electrical specifications match the power supply.
- Cable Splicing: If necessary, splice the motor cable to the drop cable using waterproof splice kits designed for submersible applications. Ensure all connections are watertight and mechanically secure.
- Motor Mounting: Securely attach the motor to the pump assembly according to the pump manufacturer's instructions.
- Lowering into Well: Carefully lower the motor and pump assembly into the well, ensuring it does not hit the well casing walls. Maintain proper clearance from the bottom of the well.
- Electrical Connection: Connect the drop cable to the control box or power supply, ensuring correct phase rotation for three-phase motors. Install appropriate overcurrent and undervoltage protection.
- Grounding: Properly ground the motor and control box according to electrical codes to prevent electrical hazards.
5. Operating Instructions
Once installed, follow these guidelines for operating your Franklin Electric submersible motor:
- Initial Start-up: After installation, allow the well to recover and fill with water before starting the pump. Briefly run the pump to check for proper operation and rotation.
- Continuous Operation: The motor is designed for continuous duty when fully submerged. Avoid frequent starts and stops, as this can reduce motor life.
- Monitoring: Periodically monitor the pump's performance, including water flow and pressure, to detect any anomalies.
- Dry Run Protection: It is highly recommended to install a dry run protection device to prevent motor damage if the water level in the well drops too low.
6. Maintenance
The Franklin Electric submersible motor is designed for minimal maintenance. However, periodic checks can help ensure optimal performance and extend its lifespan.
- Annual Inspection: Have a qualified technician inspect the entire well system annually, including electrical connections, control box components, and pump performance.
- Water Quality: If water quality issues (e.g., sand, sediment) are present, consider installing appropriate filtration or consult a well professional for solutions.
- Cable Integrity: Ensure the motor cable and drop cable remain free from damage.
- Control Box: Keep the control box clean and free from moisture and debris.
7. Troubleshooting
This section addresses common issues you might encounter with your submersible motor. For complex problems, contact a qualified service technician.
| Problem | Possible Cause | Solution |
|---|---|---|
| Motor does not start | No power, tripped breaker, faulty control box, motor overload. | Check power supply, reset breaker, inspect control box, allow motor to cool. |
| Low water pressure/flow | Low well water level, clogged pump intake, worn pump components, pipe leaks. | Check well level, inspect pump, check for leaks, consult technician. |
| Motor runs continuously | Leaking check valve, pressure switch malfunction, continuous demand. | Inspect check valve, test pressure switch, verify system demand. |
| Excessive noise or vibration | Pump cavitation, worn bearings, foreign object in pump. | Check well level, inspect pump for obstructions, contact technician. |
