in order to eliminate any residual particles
which could otherwise get stuck in taps or
valves thus preventing them from working
properly. Connect the water supply
connection of the espresso machine to
the water pump outlet using one of the
supplied stainless steel braided hoses.
Then connect the water pump inlet to the
water filter/softener outlet (if present).

otherwise air can be introduced into
the brew boiler causing an undesireable
condition and damage to the pump.
