INSTALLATION
Before installing the machine, read carefully this manual.
Install the machine in a dry and hygienic place.
ELECTRIC CONNECTION
Before connecting the machine to an electric plug, please follow these precautions:
• The main supply must correspond to the power requirements of the machine
(1600W).
• Check that the power supply voltage correspond to the voltage shown in the
rating label.
• Check that the main socket is correctly earthed.
• If the power supply cable is replaced, use only original type cables (request the
special cable with M type connection to the manufacturer).
The manufacturer will not accept responsibility for any
damage arising if these precautions are not complied
with.
All the electric devices in the machine work with a 24 Vdc voltage, except the
boiler heating element and the transformer that work with 230 or 115 Vac.
HYDRAULIC CONNECTION
Connect the black pipe to the mains.
Check that the mains pressure is not over 4 bar, otherwise you must install
a pressure reducter.
Movements nr 14 and 15 (Decounter 1 and 2)
The movements #14 (decounter 1) and #15 (decounter 2), where inserted, decrease the relative decounter by a unit.
To set the value of the decounter, it is enough to change it in one selection which
contains it, automatically it will be modified also in all the other selections.
If the parameter “type” is set=0, every time it is reset, see at page 22, the decounter restart to the set value, while if the parameter “type” is set=1, at every reset,
the decounter value will be the sum of the set value plus the value before the reset.
Example with value= 100 and type=0
If the decounter is reset when its value was 20, the new decounter value is 100.
Example with value=100 and type=1
If the decounter is reset when its value was 20, the new decounter value is 120
(100+20).
In both of cases, when the decounter reaches 0, the machine will disable the selections which contains the relative decounter (movements 14 and 15).
