How to read the water pressure gauge (Aquarea J)

Summary (editorial)

Low water pressure is a common reason for flow and high-pressure errors. Reading the gauge is safe and takes a minute; the manual gives the normal range.

From the manufacturer's documentation (English source wording, with page)

  1. Water pressure gauge – main component 4[1]
  2. Pressure gauge reading should be in between 0.05 mpa and 0.3 mpa[2]
  3. Pressure relief valve check – clacking sound[3]
  4. Expansion vessel 6 l, initial pressure 1 bar[4]
  5. Total water volume below 150 l without antifreeze, otherwise extra vessel[5]

⚠ Work on refrigerant circuits, mains electricity and PV DC wiring is for qualified technicians only.
