Installation tips

  • Correct dimensioning of the tank with respect to use it; an incorrectly dimensioned tank and/or pressure tank can use damage/injury to objects/persons. Dimensioning must be performed by specialised technicians.
  • Correct installation performed by specialised technicians in compliance with current national Standards, respecting the prescribed tightening torque values of the fitting (fig. 1) and the assembly suggestions (fig. 2). In the event of several tanks in series or parallel, they must be connected at the same height. If tanks with volumes over 12 l are mounted with fitting upwards, a suitable support is necessary (fig. 3); do not install the tank cantilevered if it is not supported (fig. 4)
  • The heating tank must be installed in proximity of the boiler and connected to the return or back-flow piping (fig.5).
  • The pressure tank must be positioned in pump flow (fig. 6).
  • Install the expansion tank in a suitable place and in a way to prevent damage due to water leaks.
  • A safety valve must be present in the plant, with pressure calibration lower than or equal to the maximum pressure of the tank and/or pressure tank; absence of the safety valve with the max operating pressure exceeded, can cause serious injury/damage to persons, animals and objects.
  • Initial pre-charge pressure stated on the label and for standard applications; can be regulated 0,2 bar lower than the pressure switch start setting; within the range of 0,5-3,5 bar. The pre-charge must be controlled (with calibrated manometer applied to the valve) before product installation.
  • Prevent corrosion of the painted tank by not exposing it to aggressive environments. Make sure that the tank does not constitute a conductive part and that there are no stay current in the plant on order to prevent the risk of tank corrosion.
