NV45B5FE3T Booster Pump 45GPM

Installation Instructions for NV45B5FE3T Booster Pump

1. Preparation:
   • Inspect the pump and motor for visible damage during shipping. Report any issues to the carrier or dealer immediately.
   • Ensure the installation site is level, stable, and provides adequate space and ventilation for motor cooling and maintenance.
   • Verify that the pump model and motor specifications match the system requirements and application.
2. Mounting the Pump:
   • Secure the pump base to a flat, solid surface to minimize vibrations during operation.
   • Align and support the suction and discharge piping to prevent excessive strain on the pump.
   • Install isolation valves on both the suction and discharge sides for easier servicing and maintenance.
3. Piping Connections:
   • Ensure piping matches the pump’s 2" ANSI 150# flanged connections.
   • Install gaskets to prevent leaks and ensure proper sealing.
   • Remove any protective covers or caps from the flanges before installation.
   • Include a bleed valve in the discharge line for hot water systems to relieve pressure during servicing.
4. Electrical Connection:
   • Have a certified electrician verify the electrical supply matches the motor’s specifications (5 HP, three-phase).
   • Ensure correct motor wiring and confirm counterclockwise rotation when viewed from the motor’s rear.
   • If rotation is incorrect, reverse any two leads on a three-phase motor to correct it.
5. Priming the Pump:
   • Remove the fill plug and fill the pump casing with water using a funnel.
   • Open the vent plug to allow air to escape as the pump fills with water.
   • Re-seal the vent and fill plugs once a steady stream of water flows from the vent.
6. Initial Testing:
   • Fully open the suction valve and partially open the discharge valve.
   • Apply power to the motor and monitor for smooth operation without unusual noise or vibration.
   • Gradually open the discharge valve to achieve the desired operating conditions.
7. Safety Precautions:
   • Never operate the pump without water to avoid damaging internal components.
   • Replace coupling guards after installation to ensure operator safety.
   • Ensure the pump is properly grounded and all connections are secure before starting.
