3.9 Machine start-up
After getting equipped the water supply to the
machine, turn the machine on using the main switch of
the machine (1).
Before using the machine, wait for a short time
(about 20 min.) until the gauge (2) indicates the correct
working pressure (1-1.2 bars).
!
During the machine's warm-up phase
(roughly 20 minutes), the negative pressure valve
will release steam for a few seconds until the valve
itself closes.
PriBefore using the machine, run deliveries dry
with the lter holfer attached for a few second to
release any air which may be in the circuit, so that
the delivery groups are completely heated.
Before using the machine, dispense a few servings
of coffee to test the grinding and to check the
operating pressure of the machine.

3.8 Wiring
It is necessary to link a safety main
switch (A) on the electric panel, as required
by standard regulations.
Machine with INTERNAL MOTOR PUMP
Connect the power cable as set forth in the chapter
"Electrical diagrams" (the cable has a cross-section and
number of wires based on the power and voltage of the
machine).
Machine with EXTERNAL MOTOR PUMP
1. Connect the motor pump cable (with smaller cross
section) to the connector of the external motor as
shown in the diagram below.
2. Connect the machine power cable (with larger
cross section) as set forth in the "Wiring diagrams"
chapter.
!
Always connect the motor pump cable before
the machine power supply cable, in accordance
with the diagram provided. Failure to comply
with the instructions given above may cause
serious damage to the machine and/or motor
pump and will invalidate the warranty. Carry
out the electrical connections only when the
machine is disconnected from the power supply.
