4.2.5 Refrigerant System Operation
When switching on the control unit for the first times there will be a delay of three minutes in
the compressor and evaporator fan starting .
During normal working, the compressor will stop only after reaching the set point temperature
and the evaporator fans will work always.
When opening the door (if there is a door switch) both the compressor (if working) and fans
will stop.
When closing the door, the fans will start immediately, while the compressor will have a delay
of three minutes from the last switching off, even if the door is closed before.
The cooling unit is controlled by various parameters inserted in the software of the control unit
and unchangeable by the User, this avoids possible and unwanted modifications to the same
parameters, that could cause a malfunctioning of the cooling unit. In any case, for any
particular needs it is possible to contact the technical assistance service that will assist you in
various problems.
