4. Specifications

Dimensions of the Acquaer SJC050 pump: 13.6 inches length, 8.4 inches width, and 7.1 inches height.

5. Installation and Setup

5.1 Electrical Connection

The Acquaer SJC050 pump features a dual voltage motor (115V/230V) and is factory wired for 230V. Ensure the correct voltage is selected before connecting to power.

• Verify Voltage: Check your power supply voltage.
• Adjust Switch (if necessary): If your power supply is 115V, you must switch the voltage selector inside the voltage box to the 115V position. Refer to the diagram below.
• Wiring: All electrical connections must comply with local electrical codes and be performed by a qualified electrician.

5.2 Plumbing Connections

• Suction Line: Connect a 1-1/4 inch NPT pipe to the pump's suction inlet. Ensure all connections are airtight to prevent air leaks.
• Discharge Line: Connect a 1 inch NPT pipe to the pump's discharge outlet.
• Check Valve: Install a check valve in the suction line to prevent water from flowing back into the well when the pump is off.
• Pressure Tank: For optimal performance and reduced cycling, connect the pump to a properly sized pressure tank.

5.3 Priming the Pump

Before initial startup, the pump must be primed (filled with water) to ensure proper operation and prevent damage from dry running.

1. Remove the priming port plug located on top of the pump.
2. Fill the pump casing completely with clean water until it overflows from the priming port.
3. Replace the priming port plug securely.
4. Ensure all valves in the suction and discharge lines are open.

6. Operating Instructions

6.1 Initial Startup

1. Ensure the pump is properly primed and all connections are secure.
2. Connect the pump to the appropriate power supply.
3. The pump should start and begin to build pressure. Monitor the pressure gauge.
4. Allow the pump to run until it reaches its cut-off pressure (if connected to a pressure switch/tank) or until water flows steadily from the discharge.

6.2 Thermal Overload Protector

The Acquaer SJC050 pump is equipped with a built-in automatic thermal overload protector. This feature automatically shuts off the pump motor if it overheats, preventing damage. If the pump stops unexpectedly, allow it to cool down for approximately 30 minutes before attempting to restart. Identify and resolve the cause of overheating (e.g., low voltage, prolonged dry running, excessive load).

7. Maintenance

Regular maintenance ensures the longevity and efficient operation of your pump.

• Regular Inspection: Periodically check all connections for leaks and ensure the pump is securely mounted.
• Cleanliness: Keep the pump area clean and free from debris to ensure proper ventilation.
• Winterization: In areas subject to freezing temperatures, drain the pump completely and store it in a warm, dry place or ensure all water is removed from the pump and associated plumbing to prevent freeze damage.

8. Troubleshooting

This section addresses common issues you might encounter with your jet pump.

Common Issues and Solutions:

• Pump does not start:
  • Check power supply and circuit breaker.
  • Verify correct voltage setting (115V/230V).
  • Allow motor to cool if thermal overload protector has tripped.
• Pump runs but no water or low pressure:
  • Ensure pump is properly primed.
  • Check for air leaks in the suction line.
  • Verify water level in the well.
  • Inspect for blockages in suction or discharge lines.
• Pump cycles on and off frequently:
  • Check for leaks in the plumbing system.
  • Inspect the pressure tank for proper air charge or diaphragm integrity.
  • Adjust pressure switch settings if applicable.
