Typical installation diagram for open loop hot water recirculation systems

Figura 3: Typical installation for open loop hot water recirculation systems. This diagram illustrates the placement of the circulator pump, isolation valves, backflow preventer, thermal expansion tank, hot water tank, drain valves, and flow check valve within a plumbing system.

Follow the diagram above for proper placement of the pump and associated components. Ensure that isolation valves are installed on both sides of the pump to allow for easy servicing without draining the entire system. A backflow preventer and thermal expansion tank are recommended for system integrity.

4.2 Conectarea cablului de alimentare

The pump comes with a pre-attached power cord. Locate the power cord connection point on the pump.

6. Întreținere

Regular maintenance ensures the longevity and optimal performance of your wassermann ECM Circulator Pump. Always disconnect power before performing any maintenance.

  • Inspectie periodica: Periodically check for any leaks around the pump connections. Tighten connections if necessary.
  • Curăţenie: Keep the exterior of the pump clean and free from dust or debris.
  • Spălarea sistemului: If the pump is part of a heating or hot water system, follow the manufacturer's recommendations for system flushing to prevent sediment buildup.
  • Material Advantage: The pump head is constructed from stainless steel, which offers superior resistance to corrosion compared to cast iron pump heads. This contributes to cleaner water quality and a longer service life, reducing the need for frequent maintenance related to rust.
