5.7 Defrost on glass dorr coolers (GDC)
Defrost cycles minimize the risk of the evaporator icingup. The defrost cycle occurs periodically as definedby
the defrostinterval (dE). The defrost interval starts when the ems controller is powered up or at the end of an
uninterrupted pull down. Some ems controllers also enable defrost cycles to be started manually.
The defrost cycle ends after the time defined by the defrost duration (dd) or on reaching the defrost termination
temperature (dtd), as shown below:
For more information about the parameters used in defrost:
• See ”defrost duration (dd)”
• See ”defrost interval (dE)”
• See ”defrost termination temperature (dtd)”
Note
Manual defrosts also end after the defrost duration(dd) or on reaching the defrost termination
temperature (dtd).
5.8 Freeze-up protection
Freeze-up protection prevents over cooling. Freeze-up protection occurs if the temperature measured on the
appliance sensor falls below the freeze-up protection (dtt) temperature. During freeze-up protection, ems
controllers display “888” and stop the compressor to prevent further cooling. ems controllers then resume normal
operation when the temperature rises to the freeze-up protection (dtt) temperature plus the differential (dIF)
temperature. For ems controllers that manage the evaporator fan, the ems controller starts the evaporator fan cycle.
