Then connect the inlet of the water filter/
softener (if present) to the drinking water
supply using one of the supplied stainless
steel braided hoses. Before connecting the
filter to the water pump, flush the water
supply line and the filtration system 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).
Note: The water pump is a differential
pressure volumetric pump and has been
designed to be used exclusively with cold
water. Make sure that water is always present
while the pump is operating, otherwise air
can be introduced into the brew boiler
causing an undesireable condition and the
pump can be damaged.
