2. Safety Information
Always observe basic safety precautions to reduce the risk of fire, electric shock, and personal injury. Failure to follow these instructions may result in serious injury or death.
- Electrical Safety: Ensure all electrical connections are made by a qualified electrician and comply with local codes. Disconnect power before servicing.
- Grounding: The motor must be properly grounded to prevent electric shock.
- Water Quality: Do not use this pump for flammable liquids or in hazardous locations.
- Lifting: Use appropriate lifting equipment when handling the pump motor due to its weight.
- Temperature: Do not operate the motor in ambient temperatures exceeding 86°F (30°C).
3. Setup and Installation
Proper installation is crucial for the performance and longevity of your submersible pump motor. Consult a professional for installation if you are unsure about any steps.
- Pre-Installation Check: Verify that the motor specifications (voltage, HP, phase) match your power supply and pump requirements. Inspect the motor for any shipping damage.
- Motor-Pump Assembly: Carefully align and attach the motor to the pump end, ensuring the splined shaft engages correctly. Secure all fasteners according to the pump manufacturer's recommendations.
- Electrical Connections: Connect the motor leads (3 wires) to the control box or power supply. Ensure all connections are watertight and insulated using appropriate splicing kits for submersible applications.
- Grounding: Connect the motor's ground wire to a reliable earth ground.
- Lowering into Well: Use a strong, non-corrosive safety rope or cable attached to the pump assembly. Carefully lower the pump and motor into the well, ensuring it hangs freely and does not touch the well casing.
- Pipe Connection: Connect the discharge pipe to the pump outlet. Ensure all pipe connections are secure and leak-free.
4. Operation
Once installed, the motor is designed for continuous operation within its specified parameters.
- Initial Start-up: After installation, prime the pump if necessary (refer to pump manual). Restore power to the system. The motor should start smoothly.
- Monitoring: Observe the system for unusual noises, vibrations, or leaks during initial operation.
- Water Level: Ensure the well water level remains above the pump intake during operation to prevent dry running, which can damage the motor.
- Thermal Protection: The motor features automatic thermal protection. If the motor overheats, it will shut off and restart once it cools down. Investigate the cause of overheating if this occurs frequently.
5. Maintenance
The Franklin submersible pump motor is designed for minimal maintenance. However, periodic checks of the overall pumping system are recommended.
- Annual System Check: Have a qualified technician inspect the entire well system annually, including the pump, motor, control box, and pressure tank.
- Electrical Connections: Periodically check for loose or corroded electrical connections in the control box.
- Water Quality: Monitor water quality for excessive sediment or abrasive particles, which can reduce pump and motor life.
- Motor Housing: The corrosion-resistant stainless steel shell requires no specific maintenance.
6. Troubleshooting
Refer to the following table for common issues and their potential solutions. Always disconnect power before attempting any troubleshooting or repairs.
| Problem | Possible Cause | Solution |
|---|---|---|
| Motor does not start | No power; tripped breaker; faulty control box; wiring issue. | Check power supply, reset breaker, inspect control box components, verify wiring connections. |
| Motor runs but no water | Low well water level; clogged pump intake; faulty pump end; air lock. | Check well level, inspect pump intake, consult pump manual, bleed air from system. |
| Motor cycles frequently | Pressure tank issue; leaky plumbing; low well yield. | Inspect pressure tank, check for leaks, assess well capacity. |
| Motor overheats and shuts off | Low voltage; excessive load; insufficient cooling flow; dry running. | Verify voltage, reduce load if possible, ensure proper water flow around motor, check well level. |
