8.8 Alarm warnings

In case of an anomaly, the microprocessor will activate an alarm and the display will show the corresponding warning
codes which identify the cause. All alarm warnings will automatically stop as soon as the normal conditions of opera-
tions are restored.
Warnings "P1 - "P2" - "P3"
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 a suitable refrigerated place (i.e. cold-rooms, another refrigerated cabinet) if it is neces-
sary.
Warning "HA"
This warning indicates a high temperature for preserving the displayed products. Check the temperature with the digi-
tal thermometer (it is inside the refrigerated cabinet) and the loading conditions of the displayed products (refer to
Chapter 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 "HA2"
If the refrigerated cabinet is equipped with the "SCE" (efficient condenser system), there is an additional probe for the
measurements of the condensation temperature. The warning indicates a reduced efficiency of the unit caused by the
accumulation of dirt on the front surface of the condenser. Clean the condenser as described chapter "7 User's
maintenance". If the warning remains, even after the cleaning operation, call for Technical Support.
A dirty condenser causes higher energy consumption and stresses the compressor resulting in a decrease of
duration of the compressor. Check the condenser periodically and clean it as given in the Scheduled maintenance
calendar in chapter "7 User's Maintenance".
This type of warning, in addition to the normal displayed messages, activates an intermittent sound signal. All
alarm warnings will automatically stop as soon as the normal conditions are restored (i.e. clean condenser).
