6. RENEWAL OF WATER
In the event that the machine remains inactive for more than a week, it is necessary to change the water contained within
the whole machine, follow the instructions as indicated in point 3. 4 ..
7. TURNING THE MACHINE ON
Before turning on the machine, make sure that the water level inside the boiler is sufficient (visible from the optical level,
located inside the machine on the right side, visible by removing the right side or the cup support grid), in the case of an
insufficient and / or absent level proceed with manual loading, in order to avoid overheating of the resistance. The machine
is equipped with a system that interrupts the power supply of the electric heater in case of insufficient and / or absent water
level, and will automatically load the water in the boiler before powering the resistance.
Open the water mains tap and the machine tap.
Turn the switch to position 1 or ON.
Wait for the machine to carry out all the checks and checks (any electrical and electronic problems, filling the boiler).
The display (if any) shows the water level inside the boiler and the steam temperature inside the boiler which, when fully
operational, must stabilize at around 120 ° C. If present, the temperatures of the individual groups are also displayed.
During the machine heating phase, the anti-depression valve may release steam for a few seconds, until the valve closes.
8. PRELIMINARY OPERATIONS
It is important to have a grinder-doser next to the machine with which to grind the coffee. To obtain a good espresso, it is
advisable not to keep large stocks of coffee beans and to respect the expiry date indicated by the manufacturer. Never grind
large volumes of coffee, it is recommended to grind only the quantity used daily. Do not buy and / or use already ground
coffee, as it quickly deteriorates.
Fill the filter with a dose of ground coffee (about 6-8 gr.) And compress it with the special press, hook the filter holder to the
group without closing it too much, to avoid rapid wear of the seal. For the same reason, it is advisable to clean the edge of
the filter every time before attaching the filter holder to the group.
Before using the machine, make several empty dispensings with the filter holders attached in order to release any air
present in the circuit and allowing the complete heating of the dispensing groups.
Also carry out some coffee dispensing with different grinding tests to check the most suitable grinding and to check the
operating pressures of the machine. Never remove the filter holder from the group when brewing coffee, risk of burns.
9. COFFEE PREPARATION
Hook the filter holder with the coffee to the group, place the cup or cups under the spout, press the desired dispensing
switch to obtain the coffee dispensing, which will stop automatically when the programmed quantity is reached or can be
stopped in advance by pressing the dispensing switch (the dispensing times are set by the manufacturer for a correct
quantity of coffee, the dispensing times can be changed by the operator or by technical personnel as reported in the
machine programming chapter).
Place the cup or cups under the spout and press the desired dose button and wait for the coffee to be dispensed (during
delivery, the LED corresponding to the button pressed will remain lit.
To stop coffee delivery early, press the button with the LED on.
10. PREPARATION OF HOT DRINKS
10.1 HOT WATER DELIVERY
Place the jug under the hot water wand and press the hot water button (function active on all keyboards) and wait for the
end of the supply, if the quantity of hot water is insufficient press the hot water button again, the water supply hot water can
be stopped early by pressing the hot water button.
Do not touch the hot water spout, contact with the spear can cause burns and damage to people, things and animals.
10.2 STEAM DELIVERY
Insert the steam wand (s) into the liquid to be heated and operate the joystick or the tap knob, return the joystick to the
central position or the knob closed after dispensing.
Turning the knob anticlockwise the tap opens and allows the steam to escape, turning the knob clockwise closes the tap.

Apollo
Pag. 6
By moving the joystick (if provided by the model purchased) vertically, there is a continuous opening of steam, manually
return the joystick to the central position to stop steam delivery. Moving the joystick horizontally opens the steam and
automatically closes the steam when the joystick is released.
To obtain optimal swarming, it is advisable to heat only the quantity of milk to be used, once heated, it must be poured
entirely from the jug and not re-heated. The milk to be frothed must be at room temperature and at a temperature not lower
than 4 ° C.
Before each use of the steam wand, drain the condensation inside the wand by operating the tap for at least 2 seconds.
Leave the steam wand immersed in the milk only for the time strictly necessary for heating the milk.
Handle the steam wand with care, use the special anti-scald rubber, contact with the nozzle and the steam can cause burns
and damage to people, things and animals.
Clean the lance (s) with a soft, damp cloth after each use, the milk residues left on the steam wand favor the proliferation
of bacteria and mold, highly harmful to the human organism. Do not use detergents for cleaning the steam wands.
Never open the tap of the steam wand immersed in milk or other liquid with the machine off, the machine is equipped with
an anti-vacuum and anti-suction valve, in case of valve malfunction the milk is sucked into the boiler with serious damage
to the machine itself (contact the service center).
11. CUP WARMER
Place the cups to be heated on the cup warmer top, the top is heated by induction from the heat generated by the boiler
inside the machine. It is not possible to adjust the heating temperature of the cups. Do not place cups or cups that are damp
or containing liquids on the cup warmer surface, spilling liquids inside the coffee machine through the openings on the cup
warmer surface can cause serious damage to the machine. In the event of liquid spillage inside the machine, immediately
turn off and unplug the machine from the power supply and contact the service center.

NOTE 1: The minimum level probe does not perform filling control or management tasks, as this function is performed by
the level probe. (next paragraph)
NOTE 2: If the BUZZER function is enabled from the technical menu (see dedicated chapter), every time the minimum level
probe is discovered as described above, in addition to the signaling on the display, the buzzer on the back of the RGB
display board will also report the acoustic signal. , through 5 consecutive "beeps".
16.2 LEVEL PROBE
At the time of the Power-on, the dosing detects the status relative to the level probe placed in the boiler and, if necessary
(lack of water), arranges the execution of the filling phase by energizing the EVLIV filling solenoid valve and the PUMP until
the correct water level in the boiler is restored.
(Time-out foreseen in the programmable filling phase - see TECHNICAL Programming)
NOTE: When the system is turned on, the level control and adjustment is enabled after about 6 seconds.
Whenever the level probe placed in the boiler does not detect
the presence of liquid for 3 seconds, the filling phase is
arranged by energizing the EVLIV loading solenoid valve and
the PUMP. When the probe returns again to recognize the
presence of water for 3 consecutive seconds, the filling phase
is interrupted by de-energizing the EVLIV loading solenoid
valve and the PUMP.

The filling phase does not affect the possibility of making both
coffee or tea or steam selections and a new programming of
the same. Only the intervention of the Time-out combined
with the filling phase inhibits the functionality of the keyboard
and actuators.
In the first adjustment of the water level in the boiler, the level
probe is waited for before activating the ON / OFF / HEATING
/ TEA2 relay.
It is possible to vary the sensitivity of the level probes through a parameter in the TECHNICAL Programming in the following
possibilities:
-> LOW sensitivity
-> MEDIUM sensitivity
-> HIGH sensitivity

400 kΩ

Ntc 3rd Group
NTC Boiler
Resistance
Heating control of all boilers is enabled in IDLE-ON;
each uses an NTC type probe and a 4 ÷ 30Vdc low voltage
command which excite solid state relay (SSR) type actuators
or specific triac modules which in turn control the heating
resistors.
In the first setting, the heating is activated only AFTER
the level in the boiler has been reached to safeguard the
resistance.
In all other cases, heating is active if necessary except when
the minimum level probe is discovered ... condition in which
heating is immediately blocked.
During the activation of the group heaters, the resistance symbol appears on the display

when this symbol is present on the display it

SEQUENTIAL HEATING
The system provides the possibility to enable the "Sequential heating" function through a technical menu (see dedicated
chapter) which, when only one group heating SSR is activated, these have priority over the SSR output of the coffee boiler
which is
In the condition in which the "Sequential heating" function is deactivated from the technical menu, the management of the
SSRs present in the system (Coffee boiler + groups) will be without priority constraints between them.
CAUTION:
- in the first setting (temperatures not at full capacity) the heating priority will be of the boiler.
- any request for steam or tea dispensing without a coffee in progress keeps the boiler temperature active regardless of
whether the coffee group heaters are active or not
17.2 PID ADJUSTMENT (DEFAULT SETTING)
The default temperature adjustment is made following an algorithm called PID.
The constants that determine thermoregulation are called

is the range within which

mode
The three constants and the proportional range must be adapted to each type of coffee machine based on the power
characteristics of the resistance, the size of the boiler, the fluidics, its dispersion, etc., etc ... and it is usually a job that also
requires some time to get the best possible result.
"Setpoint value or T ° SET" is defined as the temperature that the boiler must be in normal operation
- If during the heating or maintenance phase the temperature fluctuates excessively around the T ° SET, with peaks of
value that does not decrease over time, it is necessary to decrease the proportional constant: Kp
- If during the maintenance phase the temperature fluctuates excessively around the T ° SET, with a very long period
of oscillation and with peaks that do not decrease over time, it is necessary to decrease the integrative constant: Ki
- If during the heating or maintenance phase the temperature fluctuates excessively and often greater than the T °
SET, but which decreases over time, it is necessary to decrease the derivative constant: Kd
- If during heating the temperature tends to stay below the T ° SET value, moving further and further away from it, it is
necessary to increase the derivative constant: Kd
- If during heating the temperature tends to stay constantly below T ° SET, it is necessary to increase the proportional
constant: Kp and also slightly increase the integrative constant: Ki
- If during the maintenance phase the temperature tends to stay below or above the value of T ° SE T it is necessary
to increase the integrative constant: Ki and slightly increase the proportional constant: Kp
(see TECHNICIAN programming for parameter setting)
17.3 ON / OFF REGULATION WITH HYSTERESIS OF 2 ° C ONLY FOR STEAM BOILER
The temperature regulation of the steam boiler can also take place in another mode and more precisely with a hysteresis
of 2 ° C. The resistance is controlled by the ON / OFF / RISC / TEA2 actuator (which the customer will have connected to
the remote control and / or power relay at will) which de-energises when the programmed temperature T ° SET is reached
(see TECHNICAL Programming) and it re-energizes when it has decreased by 2 ° C. To avoid vibrations on the intervention
threshold, a time filter is also inserted.
To activate this function, it is necessary to set all pid constants to 0 in TECHNICAL Programming (see dedicated
paragraph).
17.4 SWITCHING OFF AND SWITCHING ON OF INDIVIDUAL GROUPS
It is possible to switch off the heating of the individual boilers of the groups by pressing first the K5GRx key and immediately
after the K2GRx key. OFF is displayed instead of the temperature.

17.5 ECONOMY MODE
The ECONOMY mode is activated when the inactivity time set in the technical menu under "ECONOMY TIME" is exceeded.
The ECONOMY mode provides for the automatic lowering of the steam boiler tset to the value set by the technical menu
(see dedicated paragraph).
With economy mode active, the display shows the wording "ECO" instead of the steam boiler temperature (on the right of
the display).
Economy mode is deactivated when:
1. the measured temperature is 2 ° C lower than the set economy tset
2. any delivery is made
3. the level probe does not detect water and the loading phase is activated
18. PROGRAMS AND READINGS
18.1 COFFEE DOSES PROGRAMMING
It is possible to modify and memorize the quantities relating to the volumetric coffee doses by following the procedure below
1. In IDLE-ON state, press the K5GRx key (1..3) and keep it pressed for 5 seconds; check the transition from fixed to
flashing of the LEDs L5GRx (1..3)

3. Once the quantity of coffee with which you want to program the dose is reached, press any of the "coffee" buttons on the
keyboard relating to the group being programmed to stop dispensing the product with the consequent de-excitation of EVx
+ PUMP.
The new dose value expressed in pulses of the volumetric meter is stored in EEPROM.
At the same time the LED relative to the programmed dose turns off and the remaining LEDs turn on; it is therefore possible
to proceed with the programming of the remaining doses (also tea and steam doses if enabled) without having to repeat the
entry operation (see point 1).

2. Within 30 seconds (exit time-out from the programming phase) press any of the keys associated with the 4 doses that
can be programmed (for example K1GRx). The LED relating to the K5GRx key remains lit as is the dose LED during
programming (in our example L1GRx). EVx + PUMP actuators are enabled for the entire duration of coffee dose
programming.

· To proceed with the programming of the remaining coffee doses (if the programming time-out of 30 seconds has
not been exceeded) repeat steps 2 and 3 in sequence.
· In case of intervention of the time-out (30 seconds) on the programming phase, to proceed with the execution of
the same it is necessary to repeat the entire sequence described in points 1, 2 and 3
· ILEDs relating to the "already programmed" doses are off if you decide to return to the programming
environment. However, this does not prevent a "new" programming of the already programmed doses (this
condition is not verifiable if an ON / OFF operation of the dosage has been carried out after programming).
IMPORTANT:
the programming carried out on the FIRST GROUP is ALWAYS transferred automatically for convenience also to
all the other groups. However, this does not affect the possibility of programming the remaining groups
independently of the first one by means of the operations described in points 1, 2 and 3 also to remedy any
difference in water in the cup caused by possible "fluidic differences" with the various groups.
18.2 IF A VOLUMETRIC COFFEE DOSE IS NO LONGER ACTIVATED ...
Solving problems
if after programming a volumetric dose, it is no longer carried out, IT IS NOT TO BE attributable to the inability to store the
dose by the dosage but it is really possible that, for some reason, the dosage itself has not received the impulses from the
volumetric counter and has therefore programmed a dose equal to 0 pulses.
IMPORTANT AND VERIFY THAT THE LED OF THE DOSE SELECTED DURING PROGRAMMING DOES NOT FLASH
THE POSSIBLE CAUSE IS TO BE SEARCHED IN:
- volumetric meter wrongly connected
- volumetric meter exchanged with that of another group
- water circuit not working
- coffee filter and blocked water passages that need cleaning
- solenoid valve group that does not allow enough water to pass
- ground coffee too fine or too pressed which allows a little water to filter
18.3 TEA DOSING PROGRAMMING
It is possible to modify and memorize the quantities related to the tea doses (through timed control) following the following
procedure:
CAUTION:
IF THE "PRE-INFUSION" FUNCTION IS ACTIVATED (SEE DEDICATED PARAGRAPHS), THE DOSING IN THE
PROGRAMMING PHASE ENABLES THIS PARTICULAR FUNCTION IN ANY CASE. WAIT THEREFORE THAT THE
SAME IS COMPLETED BEFORE STOPPING THE CURRENT PAYMENT

Apollo Pag. 17
1. In IDLE-ON state, press the K5GRx key (1..3) and keep it pressed for 5 seconds; check the transition from fixed to
flashing of the LEDs L5GRx (1..3).
The display shows the wording '' Doses Setting Select within 30sec '' in the xxxxxxxxxxxxxx zone.
2. Within 30 seconds (exit time-out from the programming phase) press the K6GRx key associated with the tea dose. The
LED relating to the K5GRx key remains on
The EVTEA actuator is enabled for the entire duration of the tea dose programming.
3. Upon reaching the amount of tea with which you want to program the dose, press the K6GRx key used previously to stop
dispensing the product with the consequent de-excitation of EVTEA.
The new time relating to the duration of the tea dose is memorized.
· To proceed with the programming of the other tea doses (if the programming time-out of 30 seconds has not been
exceeded and you have entered the programming environment from group 1 by pressing the K5GR1 key) repeat steps 2
and 3 in sequence.
· In case of intervention of the time-out (30 seconds) on the programming phase, to proceed with the execution of the same
it is necessary to repeat the entire sequence described in points 1, 2 and 3.
· The LEDs relating to the "already programmed" doses are off if you decide to return to the programming environment.
However, this does not prevent a "new" programming of the already programmed doses (this condition cannot be verified if
an ON / OFF operation of the dosage has been carried out after programming).
IMPORTANT:
the programming of the tea dose carried out on the FIRST GROUP is NEVER automatically transferred to all the
other groups. To program the tea dose on the remaining groups, simply repeat the operations described in points
1, 2 and 3.
NOTE: during the programming of a Tea, the groups and the delivery of the other teas remain disabled.
18.4 CLOCK PROGRAMMING
In IDLE-ON state, press the K5GRx key (1..3) and keep it pressed for 5 seconds; check the transition from fixed to flashing
of the LEDs L5GRx (1..3)
The display shows the wording 'Clock Adjust'.
NOTE: when the "Doses Setting" screen is displayed, keep the K5GRx button (1..3) pressed to go to the "Clock Adjust"
phase.

To switch from one to the other, press the K5GR1 button.
1 switch on and 1 switch off can be set and are valid for all days of the week.
If you do not wish to have automatic switching on or off, go to the corresponding time programming and press K1GR1 (+)

In this case:
- if the ignition has been disabled, the shutdown and the day off are also automatically disabled, pressing K5GR1 skips the
relative settings and goes directly to the next parameter. Switching on and off can thus only be done manually through the
procedure described in the previous paragraph.
- if the ignition is enabled, pressing K5GR1 switches to the setting of the shutdown and subsequently of the closing day, if
necessary.
18.6 DAY OF REST
It is possible to define a weekly rest day, in which the dosage ignores the automatic ignition and can only be turned on
manually.
The automatic switch-off is also active on the day off.
