1.4.5.1 operational modes
in the lower part of the dispensing section installed is the refrigeration unit, which maintains the set
temperature. The temperature is maintained using the readings from 3 temperature sensors:
• Sensor №1 – Located in the lower part of the dispensing compartment;
• Sensor №2 – located in the upper part of the dispensing compartment;
• Sensor №3 – located on the refrigeration unit’s evaporator (see figure 6).
Note: Recommended temperature settings:

ATTENTION! To maintain proper settings for the refrigeration unit it is important that
temperature sensor 3 should be installed properly. It should be properly clamped on
the second last bend of the evaporator, as shown in figure 7. The sensor must be in
-
stalled before the refrigeration unit is fitted in the Machine. After the placement of the
refrigeration unit inside the Machine the Sensor’s connector must be connected to the
sensor connection strip.
The refrigeration unit’s operational modes are controlled using the Regulator. The refrigeration unit can
operate in 4 modes:
•
Standby
•
Defrosting
•
Cooling
•
