9.8 Alarm warnings _________________________________________________

In case of an anomaly, the microprocessor activates an alarm and the display shows the corresponding warning code
that identifies the cause. The symbol illuminates on the display to indicate an alarm condition.
Warnings "PR1" - "PR2" - "PR3" These warnings indicate a possible failure of the temperature probes installed in-
side the refrigerated cabinet.
Call Technical Support and have the technicians check the probe connections and replace them if it is necessary. If
the probe is broken, the refrigerated cabinet might not be able to maintain the proper temperature suitable for preserv-
ing the displayed products. Check the temperature with the digital thermometer in the refrigerated cabinet. Remove
the products and store them in an suitable refrigerated place (i.e. cold-rooms, another refrigerated cabinet) if it is nec-
essary.
Warning"AH"
This warning indicates high temperature for preserving the displayed products. Check the temperature with the digital
thermometer (it is inside the refrigerated cabinet) and the loading conditions of the displayed products (refer to Chap-
ter 6 "Loading and using the cabinet). Remove the products and store them in an suitable refrigerated place (i.e. cold-
rooms, another refrigerated cabinet) if it is necessary.
Warning "COH" or "CSd"
The refrigerated cabinet can be equipped with an additional temperature probe for measuring the condensation tem-
perature. These alarms indicate a reduced efficiency of the unit that is usually caused by the accumulation of dirt on
the front surface of the condenser. Clean the condenser as described in chapter 7 "User's maintenance". If the er-
ror continues call for the Technical Support.
A dirty condenser causes higher energy consumption and stresses the compressor resulting in a decrease of
duration of the compressor.
