CONSECUTIVE SELECTIONS
It is possible to set the number of consecutive selections
(0 to 99) (dispensed at less than 2 minutes intervals) after
which the machine will not dispense other selections until
the boiler reaches the correct temperature. With the value
set to 0 (default) the function is disabled.
TEMPERATURE SETTING
This function is used to set the operating temperature,
expressed in °C, of the boilers actually installed in the
machine.

DIRECT FUNCTIONS
INSTALLATION
Press the installation button “3” to carry out the hydraulic
system filling operations, even with the air-break full.
RESETTING THE FAILURES
Press the failure reset button “8”; the message “Running”
is displayed for a few seconds and all present failures are
reset.
Important notice!!
Access to the machine interior for maintenance and/or
repairs is via the back panel.
Therefore the machine is designed to be rotated, thus
allowing removal of the back panel.
The integrity of the machine and compliance with the
standards of the relevant systems must be checked at
least once a year by qualified personnel.
Before starting any maintenance operations requiring
parts of the unit to be removed, the machine must
always be switched off.
The operations described below must be carried out
only by personnel who have the specific knowledge of
the machine functioning from a point of view of
electrical safety and health regulations.
INTRODUCTION
To ensure correct operation for a long period, the machine
must be subjected to regular maintenance.
The following sections contain the procedures and the
maintenance schedule, which are only a general indica-
tion, as they greatly depend on the operating conditions
(e.g. water hardness, environmental humidity and tem-
perature, type of product used, etc.).
The procedures described in this chapter are not exhaus-
tive of all maintenance operations to be carried out.
More complex operations (e.g. boiler descaling) should be
carried out by qualified technicians only having specific
knowledge of the machine.
To prevent oxidation or the action of chemical agents, the
stainless steel and varnished surfaces should be kept
clean by using mild detergents (solvents must not be
used).
Under no circumstances should water jets be used to
clean the machine.
