6.4. Installation and first-time start-
up
● Position the machine unit onto the horizontal sur-
face provided for that purpose and adjust the base
feet to ensure that the machine is stable and that
vibrations are limited.
Before connecting the machine, thoroughly flush the
main water supply pipes:
● Open the main water supply taps and let the water
run at full pressure for several minutes.
● Connect to the main water supply.
● Connect the machine up to the power supply
mains.
● Connect the gas pipe.
Thoroughly flush all the water pipes of the machine:
● Leave the water supply taps running at full pres-
sure.
● Switch on main switch 1 (Fig.8): wait until the boiler
fills up to the set level.
● Switch on boiler heating element switch 2 (Fig.8)
to begin heating the water in the boiler.
● Once standard machine work conditions have been
reached with the machine in "ready for operation"
mode, switch the machine off and empty all the wa-
ter filled into the water circuit the first time, thereby
eliminating any possible initial impurities.
● Fill the machine up with water again and set it into
standard operation mode.
● Once the "ready for operation" status is reached:
- Connect the filter-holders to the dispenser units
(without coffee); operate each group head in
order to allow the water to escape for about one
minute.
- Dispense hot water until at least 2 liters of water
have been dispensed from the 1-group or 2-groups
compact, 5 liters from the 2-groups machines, 8
liters from the 3-groups machines and 11 liters
from the 4-groups machines.
- Open each steam dispensing point for 1 whole
minute.
Once installation is terminated, the installa-
tion technician MUST issue an installation
report.
