Safety Information
Always prioritize safety during installation, operation, and maintenance. Read all instructions carefully before proceeding. Electrical work should only be performed by qualified personnel.
- Disconnect power before servicing the pump.
- Ensure proper grounding to prevent electrical shock.
- Wear appropriate personal protective equipment (PPE) during installation and maintenance.
- Verify that the well casing is free of debris before lowering the pump.
- Do not operate the pump dry; ensure it is fully submerged in water.

Installation and Setup
Proper installation is crucial for the efficient and safe operation of your deep well pump. This section provides general guidelines. Refer to the included installation manual for detailed, step-by-step instructions.
- Well Preparation: Ensure the well is clean and free of obstructions. The pump requires a 4-inch or larger well casing.
- Electrical Connection: Connect the pump's 2-wire (plus ground) lead wires to the power supply. Use the provided waterproof splice kit for secure and watertight connections. No external control box is needed for this 2-wire pump.
- Piping: Attach the discharge pipe to the pump's 1-1/4-inch FNPT discharge. Use appropriate pipe and fittings, ensuring all connections are watertight. Consider using a torque arrestor to prevent pump rotation within the well.
- Lowering the Pump: Carefully lower the pump into the well using a safety rope or cable attached to the pump. Ensure the pump is suspended at the recommended depth, typically 5-10 feet above the bottom of the well and below the dynamic water level.
- Surface Connections: Connect the discharge pipe to your pressure tank, pressure switch, and other plumbing components. Install a check valve if not already integrated into the pump or system.
- System Priming: Once installed, prime the system according to your pressure tank and plumbing setup.
- Power On: Restore power and check for proper operation and leaks.

Operating Instructions
Once properly installed, the Red Lion RL12G05-2W2V pump operates automatically in conjunction with your pressure switch and pressure tank to maintain water pressure in your system.
- Initial Start-up: After installation and priming, turn on the power supply to the pump. The pump will begin to fill the pressure tank and build system pressure.
- Automatic Operation: The pressure switch will automatically turn the pump on when system pressure drops below the cut-in setting and turn it off when the pressure reaches the cut-out setting.
- Monitoring: Periodically check the pressure gauge to ensure the pump is maintaining consistent pressure within the desired range.
- Water Usage: The pump is designed to handle typical household water demands. Avoid excessive continuous operation, which can lead to overheating.
Maintenance
Regular maintenance helps ensure the longevity and optimal performance of your deep well pump.
- Annual Inspection: Have a qualified professional inspect the pump and well system annually.
- Check Pressure Tank: Verify the air pre-charge in your pressure tank periodically, typically once a year, with the pump off and system drained.
- Monitor Water Quality: If water quality changes (e.g., sediment, discoloration), it may indicate an issue with the well or pump.
- Listen for Unusual Noises: Any new or unusual noises from the pump or system should be investigated promptly.
- Protect from Freezing: Ensure all exposed piping and components are protected from freezing temperatures.
Troubleshooting
This section provides common troubleshooting steps for issues you might encounter. For complex problems, contact a qualified pump technician.
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not run | No power, tripped breaker, faulty pressure switch, motor issue | Check power supply and breaker. Inspect pressure switch. Consult technician for motor issues. |
| Low water pressure | Low well water level, clogged screen, pipe leak, faulty pressure tank | Check well level. Clean suction screen. Inspect plumbing for leaks. Check pressure tank pre-charge. |
| Pump cycles too frequently | Waterlogged pressure tank, small leak in system, faulty check valve | Check pressure tank pre-charge. Locate and repair leaks. Inspect or replace check valve. |
| No water delivered | Pump not submerged, air in system, clogged intake, pump failure | Verify pump depth. Bleed air from system. Clear intake. Consult technician. |
