Warnings for the installer

3.1

Power

The water supply of the appliance must be car-
ried out with water which is suitable for human
consumption, in compliance with the regulations
in force int the place of installation. The owner /
manager of the system must confirm to the installer
that the water meets the above listed requirements.
3.2

Materials to be used

During the installation of the appliance the com-
ponents and materials that were provided with the
appliance are to be used. Should the use of other
components be necessary, the installer must verify
their suitability to be used in contact with water
used for human consumption.
3.3

Hydraulic connections

The installer must carry out the hydraulic connec-
tions in accordance with the hygiene norms and the
hydraulic safety norms for environmental protection
in force in the place of installation.
3.4

Installation report

When installation is complete, the appliance
has to be started, brought to the nominal working
condition and left for 30 minutes in the "ready to
operate" condition.
Afterwards, the appliance has to be turned off
and emptied of the first water introduced in the
whole hydraulic circuit, to eliminate possible initial
impurities.
Then the appliance must be once again loaded
and brought to the nominal working conditions.
After having reached the "ready to operate"
condition, the following deliveries have to be per-
formed:
User manual
For each coffee unit, carry out a continuous de-
livery, in order to release at least 0.5 liters of the
coffee circuit. In the case of several dispensing
points matched with the same exchanger/cof-
fee boiler, divide the volume on the base of the
number of the dispensing points;
Release the whole volume of hot water inside the
boiler (3 litres for 1GR, 6 litres for 2GR, 8 litres for
3GR), by performing a continuous delivery from
the appropriate nozzle. In the case of several dis-
pensing points, divide the volume on the base of
the number of the dispensing points;
Continuously release steam for at least 1 minute
for each steam dispensing point.
3.5

Maintenance and repairs

After ta maintenance and/or repair intervention,
the components used must ensure that the hygiene
and safety requirements initially foreseen for the ap-
pliance are still met. These are met by using original
spare parts only.
After a repair or a substitution of components
related to parts in direct contact with water and
food, a washing procedure has to be carried out, as
in the case of first installation.
