1) Installation guide
For best results, STRADA needs a minimum flow of water in input of 100 l/h and a pressure of 2.5 bar.
Installations that do not meet these requirements will cause a shorter life of the pump and may cause a high noise level during coffee
brewing.
If the pressure and flow are not adequate, air bubbles may develop within the gears. This is called cavitation. Cavitation can impair the
performance of the espresso machine STRADA.
If the incoming water of the STRADA falls outside the recommended parameters, it is necessary to carry out one of the following
installations:
