The PM Guard pressure manager allows you to connect your Grundfos SCALA2 directly to the city water mains, ensuring compliance with local regulations and protecting the water mains network and upstream appliances from water shortages. The wall-mounted device monitors water pressure and deactivates SCALA2 if the pressure drops below a specified limit. It can be set to restart manually or automatically when pressure is restored.


Why should you select PM Guard for a SCALA2 installation?

  • Automatic Shut-off: PM Guard deactivates the SCALA2 booster pump when the water pressure drops below a specified limit, preventing damage and ensuring compliance with regulations such as DIN 1988-500 (Germany), EN 806-2 (Europe), and NEN1006 (Netherlands).
  • Easy Installation: The wall-mounted device comes preassembled with all power connections and presets built in. The T-piece made of Drinking Water compliant stainless steel ensures quick and easy installation.
  • User-Friendly Display: The two-line visual display on the operating panel shows water mains pressure, SCALA2’s current consumption, and logs shut-off events and faults with timestamps.
  • Adjustable Settings: PM Guard allows for manual or automatic reset settings and easy adjustment of minimum pressure, time delay, and other parameters to meet local municipal restrictions.

What are the key features?

  • Presets for Compliance: Simply select your country on the display, and PM Guard will automatically apply the necessary settings to comply with local regulations. If your local municipal restrictions differ, adjusting settings manually is fast and easy.
  • Event Log: Access a history of shut-off events with timestamps from the operating panel, which can be shown to relevant authorities if required.
  • Durable and Reliable: Made with high-quality materials, including a pressure sensor with a 2m cable and a stainless-steel T-piece, ensuring long-lasting performance.
