needs a
minimum flow of water in input of

and a pressure of . bar.
nstallations that do not meet these
re uirements will cause a shorter life of
the pump and may cause a high noise

f the pressure and flow are not ade uate
air bubbles may de elop within the gears.
This is called ca itation. a itation can
impair the performance of the espresso
machine.
f the incoming water of the espresso
machine falls outside the recommended
parameters it is necessary to carry out one
