Power Switch
The cabinet is fitted with a power switch, usually located beside the electronic controller. Depending on the model, it may be necessary to open the unit front cover to access the switch.
Refrigeration
Unit
The compressor, and the condenser and evaporator fans should all operate within two minutes from the time the cabinet is plugged in. This may be verified by listening for compressor switch-on and checking for air movement inside the cabinet. The compressor and condenser fan will switch off when the cabinet internal air reaches a pre-set temperature.
Electronic
Controller
When the cabinet is connected to the power supply, the electronic controller will display the current cabinet temperature. The compressor symbol will come on after a few minutes, indicating the compressor and condenser fan is operating.
To ensure efficient operation, the electronic controller forces regular defrosts. During the defrost cycle, the compressor and condenser fan switch off and the evaporator fan stays on.

User Manual
SKOPE Centaur Series
Electronic Controller
Introduction
Depending on the model, the cabinet will be fitted with a CAREL Easy electronic controller or a CAREL ir33 electronic controller (refer to faceplate below to identify the type of electronic controller.
The electronic controller is visible through a cut-out in the front panel. It controls and displays the cabinet interior temperature and signals temperature alarms. It uses temperature probes around different areas of the refrigeration system to collect data and runs the cabinet accordingly .
The electronic controller is pre-programmed and requires no initial setup or additional programming. SKOPE does not recommend that the settings be changed unless it is absolutely necessary.
