Mounting: Mark anchor holes and install wall plugs rated ≥ 10 kg each. Level the bracket horizontally.
Tank Connection: Connect the expansion tank to the ¾″ male thread with PTFE tape for sealing.
System Connection: Attach inlet/outlet pipes (Ø32 or Ø42 mm) and ensure gasket alignment.
Pressure Test: Fill the system and verify gauge stability and leak-free joints.
Final Adjustment: Confirm safety-valve and air-vent orientation before operation.
Inspect brackets, fasteners, and seals every 6–12 months.
Replace O-rings and gaskets showing wear or corrosion.
Clean gauge face; recalibrate if necessary.
Re-coat exposed surfaces in humid or coastal sites every 2 years.
Avoid over-tightening during tank reinstallation.
