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.
5) Electrical connections
a) Power supply cord
• This is the main power supply cable
that provides power to the entire espresso
machine. There are different types of cable
based upon the electrical requirements of
the espresso machine purchased:
• 200/220VAC 1 Phase 3-core cable with
4/6/10mm2 cross section or AWG 12/10/8
for 2,3 4 group versions, secured to espresso
machine via a strain relief connector
• 220VAC 3 Phase 4-core cable with 4 mm2
cross section for 2 , 3 and 4 group versions,
secured to espresso machine via a strain
relief connector
• 380 VAC 3 Phase 5-core cable with
2.5mm2 cross section for 2, 3 and 4 group
versions, secured to espresso machine via a
strain relief connector.
b) Water pump motor power cord
This is the power supply for the water pump
motor. The internal electronics will switch
the pump motor on when needed.
• 3-core cable with 1.5 mm2 cross section
or 3-core AWG 16 (for UL version) secured
to espresso machine via a strain relief
connector.
c) Quick connection between the water pump and
the espresso coffee machine
The electrical connection must be made
through the use of the connectors, as
shown in the following figures:

ARE FIRMLY SECURED TO THE BODY OF THE MACHINE
IN ORDER TO PREVENT INADVERTENT STRESS ON THE
POWER CABLES.
