2. Safety Information

WARNING: Always disconnect power before servicing the pump or motor. Failure to do so can result in serious injury or death.

• Ensure all electrical connections comply with local codes and regulations.
• The pump must be properly grounded to prevent electrical shock.
• Do not operate the pump in an explosive atmosphere or near flammable liquids.
• Protect the pump from freezing temperatures.
• Wear appropriate personal protective equipment (PPE) during installation and maintenance.
• This product contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. Wash hands after handling.

3. Setup and Installation

Proper installation is crucial for the efficient and safe operation of your jet pump. Follow these guidelines carefully.

3.1 Site Selection

• Install the pump as close to the water source as possible.
• Ensure the pump is on a firm, level surface to minimize vibration.
• Protect the pump from weather elements and freezing temperatures.

3.2 Plumbing Connections

• The pump features a 1 1/4-inch suction port and a 1-inch discharge port. Use appropriate piping and fittings.
• A check valve or foot valve is required in the suction line to maintain prime.
• Ensure all connections are airtight to prevent air leaks, which can affect pump performance.

3.3 Electrical Connections

• The heavy-duty motor is dual-voltage (230V/115V). Refer to the motor wiring diagram for proper voltage selection and connection.
• The pump comes with a prewired 30/50 PSI pressure switch.
• Ensure the power supply matches the pump's voltage requirements and is protected by an appropriately sized circuit breaker (e.g., 15 amp on 230V / 20 amp on 115V).

3.4 Priming the Pump

The FP4022 is self-priming after the pump housing is initially filled with water. Before first use or after any service that drains the pump, remove the priming plug and fill the pump casing completely with water. Replace the plug securely before starting the pump.

4. Operating Instructions

Once installed and primed, the pump operates automatically based on the pressure switch settings.

• Ensure the power supply is connected and turned on.
• The pressure switch is factory preset to 30-50 PSI. The pump will turn on when system pressure drops to 30 PSI and turn off when it reaches 50 PSI.
• Monitor the system for any unusual noises or leaks during initial operation.
• The pump has a maximum flow rate of 720 GPH (12 Gallons Per Minute) at 40 PSI.

5. Maintenance

Regular maintenance ensures the longevity and optimal performance of your Flotec jet pump.

• Winterization: In areas subject to freezing, drain the pump completely and store it in a warm, dry place or ensure all water is removed from the pump and piping to prevent freeze damage.
• Inspection: Periodically inspect the pump and piping for leaks, corrosion, or damage.
• Cleaning: Keep the motor vents clear of debris to ensure proper cooling.
• The pump is a serviceable unit. Refer to the repair parts diagram for component identification if service is required.

6. Troubleshooting

If your pump is not operating as expected, review the following common issues and solutions.

• Pump does not start: Check power supply, circuit breaker, and electrical connections. Ensure the motor is not seized.
• Pump runs but delivers no water or low pressure: Verify the pump is properly primed. Check for air leaks in the suction line. Ensure the foot valve or check valve is functioning correctly. Inspect for blockages in the suction or discharge lines.
• Pump cycles too frequently: This may indicate a leak in the plumbing system or a problem with the pressure tank (if installed). Check the pressure switch settings.
• Excessive noise or vibration: Check for loose mounting bolts. Inspect for foreign objects in the impeller. Ensure proper alignment of piping.
