The manufacturer explicitly emphasises the necessity of being particular in testing the tightness
of the heating circuit (radiators, piping joints, floor heating, etc.) with the connection of the
storage tank. No pressure grow above the maximum operating pressure of 0,3 MPa in the
storage tank heating water compartment may occur, if the heating system is pressurised to
higher than the maximum operating pressure, the inner stainless exchanger may get
permanently damaged!
No stop fitting can be put between the security fitting of the heating circuit and the storage
tank!!!
