INSTALLATION
Connect the machine to the water supply mains with the water pipes (in the water cooled
condenser version) and to the power supply line with the power cable.
Power the machine.
As soon as the machine is switched on, display reads "EASYMIX120PLUS" followed by a digit
indicating the software version.
E.g.:
Easymix120Plus01
means version 01
In case of machine malfunction, your technician will always have to mention this number
as well as the machine serial number on data plate, in order to take the best advantage of
Technical Service. At the same time, all the button LED's are lit for a functional check.
After that, the set model is displayed, ex.:
Model 03
Finally (in case the machine was in Stop mode), the display will read:
15:38 10-08
EASYMIX 120 PLUS

Full Filling is always selected when the machine is started from the Stop mode. Instead, if Half
Filling is set, the cycle will restart in the Half Filling option in case of power blackout.
Note for AIR machine:
In heating mode, when TEV=50°C temperature is reached, MV activates at low speed.
When TEV reaches 83°C, MV activates at maximum speed.

10
Full Filling Cycle (120-60)
Heating
Following elements are activated in the Full Filling cycle Heating:
- Beating at speed = 5
- Heating elements (TTR and TTR2)
- Hot Gas Solenoid valve (EVGC) + EVSUP
- Compressor (MC)
The heating plate (TER) temperature is checked.
When TER reaches the value set in T24, heating is disabled (TTR OFF).
When TER1 reaches the value set in T24, heating is disabled on left side (TTR1 OFF).
When TER2 reaches the value set in T24, heating is disabled on right side (TTR2 OFF).
Heating is reactivated with a hysteresis set in T25.
When TEV reaches 40°C the display shows for 10” the following message:
PASTO+85 120-60
Add Powders
Heating will then continue until TEV reaches the temperature set
on display (Set). E.g.:
PASTO +85 120-60
+85°C +68°C
Beating is always active and set to value 5 when heating is activated.
Switching to Cooling is immediate for the +85°C and +90°C sets, whereas for the +65°C set the
mix is maintained at this temperature for 30 minutes with beating always ON (at 67°C heating
elements are deactivated and they are reactivated again at 65°C). After 30 minutes, the machine
switches to Cooling.

11
Cooling
In the first Cooling stage, the MC disables for a minute, while the cool SVs remain on.
After the first minute, the MC activates for another minute intermittently, 10” ON and 20” OFF.
After these 2 minutes, the actual Cooling starts.
Following elements are activated in the Full Filling cycle Cooling:
- Beating at speed = 5
- Compressor (MC)
- EVF1 and EVF_SUP
The display shows:
PASTO+90 120-60
+04°C +90°C
from the left: set, ramp and current TEV.
In this phase, TGV temperature for anti-freezing is checked.
Press AUTO button to display the set temperature and speed in the first page:
PASTO+90 120-60
Set +004 05
Press AUTO button again (only with step T78 = YES) to display temperatures:
TGV-005 TER2+003
TEV+90 TER+003
Press AUTO button again to return to start page.
When TGV reaches the Anti-freezing set (T06), EVGC is activated until temperature is increased
by its hysteresis (T07).
During EVGC activation, EVF and EVF_SUP are deactivated if step T29 is set to No, whereas they
remain active if step T29 is set to Yes.
On reaching the set, MC+EVGC is activated with beating always on for a programmable time
(T30). After such time, the outputs are deactivated.

12
Storage / Aging
The speed of the previous step is kept in Storage / Aging mode.
This speed can be changed by pressing the Start key to access the speed display page:
PASTO+90 120-60
Set +004 03
Then press the Speed key and change it using the Increase/Decrease keys.
On reaching 4°C Storage temperature, EVF is deactivated and MC+EVGC are activated for a
settable time at the T30 step, then all the outputs are deactivated and the machine is thermostat-
controlled indefinitely.
Therefore, if a cooling request is made (TEV=6°C), MC, EVF and Beating are activated.
Beating is then activated with the times settable at the user’s steps (U08 and U09).
Half Filling Cycle (60-40)
Half Filling cycle is activated in the same way as the full filling cycle, however in this case the
asterisk is placed to the side of “60-40”.
120-60
* 60-40

Following elements are activated:
- Beating at speed = 5
- Heating elements (TTR and TTR2)
till TEV reaches the Set.
The Hot Gas Solenoid valve (EVGC) is never activated.
The heating plate (TER) temperature is checked.
Following elements are activated in cooling mode:
- Beating (speed=5)
- Compressor (MC)

13
- EVF
Then the cycle is similar to the “Full Filling” cycle.
Half Filling Cycle Plus (60-40 plus)
Available only for pasteurization cycles.
Half Filling cycle Plus is activated by placing the asterisk to the side of “60-40 Plus”.
120-60

By selecting half filling plus, the automatic cycle will work at full filling in heating mode and at half
filling in cooling mode.

14
COOLING AGING (COOL/AGI)
In the first Cooling stage, the MC disables for a minute, while the cool SVs remain on.
After the first minute, the MC activates for another minute intermittently, 10” ON and 20” OFF.
After these 2 minutes, the actual Cooling starts.
PASTO +65
* COOLING/AGING
Also in this case, as in the case of pasteurization, the mix filling in the hopper at the beginning of
the cycle is requested.
120-60
* 60-40 Plus
full filling
half filling
Following elements are activated in cooling mode:
- Compressor
- Solenoid valve (EVF) in case of half filling cycle or EVF + EVF_SUP in case of full filling cycle
- Beating (speed=5)
In this phase, TGV temperature for anti-freezing is checked.
When TGV reaches the Anti-freezing set (programmable), EVGC is activated until temperature is
increased by its hysteresis (T07).
During EVGC activation, EVF is deactivated if step T29 is set to No, whereas it remains active if
step T29 is set to Yes.
On reaching 4°C Storage temperature, EVF is deactivated and MC+EVGC are activated for a
settable time at the T30 step, then all the outputs are deactivated and the machine is thermostat-
controlled indefinitely.
Therefore, if a cooling request is made (TEV=6°C), MC, EVF and Beating (speed=5) are activated.
After reaching the temperature, the aging time is measured as well. E.g.:
COOL/AGING120-60
+04 00:12:39 -01
At this stage Beating will start for 15 seconds every 30 minutes or each time the compressor is
activated in order to bring the mix to the set temperature.
