4. Configuración e instalación

This section outlines the typical installation process for the wassermann ECM Circulator Pump in an open-loop hot water recirculation system. Consult a qualified plumber or HVAC technician for professional installation.

4.1 Diagrama do sistema

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 Conexión do cable de alimentación

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

5.2 Indicator Meanings

Luz de correrCausa
(Sen luz)The power is off. The pump is not running.
(Luz verde)The power is on. The pump is running.
(Luz vermella)Alarm. The pump has stopped.
(Flashing green light)The pump is externally controlled.
Pantalla dixitalSignificado
CCThe pump is running in constant curve mode.
CPThe pump is running in constant pressure mode.
PPThe pump is running in proportional pressure mode.
50 WThe power of current duty point is 50W (example value).
3.0 m³/hThe flow rate of current duty point is 3.0 m³/h (example value).

Use the setting button to cycle through different operating modes (CC, CP, PP) and adjust parameters as needed for your specific application. Refer to the digital display for real-time feedback on power consumption and flow rate.

6. Mantemento

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

  • Inspección periódica: Periodically check for any leaks around the pump connections. Tighten connections if necessary.
  • Limpeza: Keep the exterior of the pump clean and free from dust or debris.
  • Lavado do sistema: 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.
