3) Accessories
In order to proceed with installation, it is
necessary that the following are available:
• Pipes carrying drinking water with a
3/8"G (BSP) end connection; (3/8"
Compression for USA and Canada)
• Electrical Supply according to the
specification of the espresso machine
purchased (not all specifications are
available in all markets):
→ Single/Three phase 220VAC - 50/60
Hz electrical connection with ground,
protected receptacle and approved
circuit breaker
→ Single phase 200VAC - 50/60 Hz
electrical connection with ground,
protected receptacle and approved
circuit breaker
→ Three-phase, 380VAC - 50/60 Hz
electrical connection with neutral +
ground, near the bench on which the
machine is installed and terminating
in a suitable protected
receptacle equipped with an approved
circuit breaker
• Waste water drain system
4) Water supply connection
In order to connect the machine up to
the water mains proceed according to the
indications given in the chapter about
Installation and in compliance with any
local/national safety standards of the
location in which the machine is being
installed.
The equipment is to be installed with
adequate backflow protection to comply
with applicable federal, state, and local
codes.
To guarantee a correct and safe functioning
of the machine and to maintain an
adequate performance level and a high
quality of the beverages being brewed it
is important that the incoming water be
of a hardness greater than 7°f (70ppm,
4°d) and less than 10°f (100ppm, 6°d),
pH should be between 6.5 and 8.5 and
the quantity of chlorides be less than
30mg/l . Respecting these values allows
the machine to operate at maximum
efficiency. If these parameters are not
present, a specific filtration device should
be installed, while always adhering to the
local national standards in place regarding
potable water.
Then connect the inlet of the water filter/
fivepole
softener (if present) to the drinking water
supply using one of the supplied stainless
steel braided hoses.
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.
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 2.5/4/6/10mm2 cross section or
AWG 12/10/8 (for UL version), secured
to espresso machine via a strain relief
connector
Before connecting
→ 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
