Installation Manual

Installation Instructions

1. Site Preparation:
   • Choose a clean, dry, and ventilated area for installation.
   • Ensure the surface is level and stable to prevent vibrations during operation.
   • Verify that the power supply matches the pump’s motor requirements (0.75 HP, 60 Hz, 3450 RPM).
2. Pump Mounting:
   • Secure the pump to the mounting surface using appropriate fasteners.
   • If equipped with a support bracket, ensure it is positioned correctly for stability.
3. Plumbing Connections:
   • Connect the suction line to the pumps inlet, ensuring it is airtight to prevent cavitation.
   • Connect the discharge line to the outlet, ensuring proper alignment to avoid stress on the fittings.
   • Install isolation valves on both the suction and discharge lines for easy maintenance.
4. Electrical Wiring:
   • Have a certified electrician connect the pump to the power source.
   • Ensure the motor is properly grounded and complies with local electrical codes.
   • Double-check the motor’s wiring diagram for correct rotation direction.
5. Priming the Pump:
   • Remove the priming port cap and fill the pump casing with water.
   • Ensure there are no air pockets in the suction line.
6. Testing and Start-Up:
   • Turn on the pump briefly to confirm proper rotation and operation.
   • Check for leaks, unusual noises, or vibrations during operation.
   • Gradually increase the flow rate to full capacity while monitoring system performance.
7. Maintenance Tips:
   • Inspect the pump regularly for wear, leaks, or loose connections.
   • Replace mechanical seals or wear rings as needed.
   • Follow the manufacturers maintenance schedule for optimal performance.
