4. Setup and Installation

Proper installation is crucial for the pump's performance and safety. If you are unsure about any step, consult a qualified professional.

  • Choose a stable, level surface for mounting. The pump should be installed below the water source if possible to aid in priming.
  • Secure the pump using the integrated mounting feet. Ensure there is enough space around the pump for ventilation and maintenance.

4.2 Plumbing Connections

  • Identify the inlet and outlet ports on the pump. The inlet typically has an arrow indicating water flow direction.
  • Install the included filter (strainer) on the inlet side of the pump to prevent debris from entering and damaging the pump. Hand-tighten only.

  • Connect your water supply line to the inlet and the distribution line to the outlet using the appropriate hose adaptors provided. Ensure all connections are tight to prevent leaks.
  • The pump is self-priming, meaning it can draw water from a source without needing to be manually filled with water first.

5. Operating Instructions

The WASSERMANN 4WDP5-55-115V pump is designed for automatic operation.

  • Once connected to power and water lines, the pump will automatically start when a tap or fixture is opened, causing a drop in water pressure.
  • The pump will automatically stop when the tap or fixture is closed and the system pressure reaches the shut-off point (55 PSI).
  • The integrated pressure switch and bypass switch work together to maintain consistent water flow and prevent frequent starts/stops, especially with small flow demands.

6. Maintenance

Regular maintenance ensures optimal performance and extends the life of your pump.

  • Inspect Connections: Periodically check all plumbing and electrical connections for leaks or damage. Tighten as necessary.
  • Clean Strainer: Regularly inspect and clean the inlet strainer to remove any accumulated debris. A clogged strainer can reduce pump performance and lead to damage.
  • Winterization: If the pump is installed in an area subject to freezing temperatures, it must be drained completely or protected with non-toxic antifreeze to prevent damage.
  • General Cleaning: Keep the exterior of the pump clean and free from dirt and dust.
