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: Make sure that water supply is
always on while the pump is operating,
otherwise air can be introduced into
the brew boiler causing an undesireable
condition and damage to the pump.

→ 220VAC 3 Phase 4-core cable with 4 mm2
cross section for versions with 1, 2 , 3 and 4
groups secured to espresso machine via a
strain relief connector
→ 380 VAC 3 Phase 5-core cable with 2.5/6
mm2 cross section for versions with 1, 2, 3 and
4 groups secured to espresso machine via a
strain relief connector.
b) Water pump motor power cord
