Page 3: Operating The Product
Operating the product Connect the product to the socket. This is done by mounting the accompanying power cord first as shown in Fig. 4, and then subsequently connecting the cord to the socket. To switch the product on and set the desired temperature for the cabinet, the uppermost panel must be flipped up and held in that position. -
Page 4: Temperature Setting
Temperature setting Set the desired cabinet temperature in the following manner: It is important to make sure first that the keyboard is not locked. See how in the section below on keyboard locking. Press the key. The compressor lamp blinks, and the current cabinet temperature setting is shown in the display. -
Page 5: Alarms
Alarms The controls can show alarms that are related to the settings for the controls or the product's operation. The following alarms can occur: High temperature alarm. This code is shown in the display if the cabinet temperature is too high in relation to the product's set point. The alarm is automatically reset when the correct temperature is re-established. -
Page 6: Error Codes On The Display
Error codes on the display If Pr1 is shown in the display, it means that there is an error on the temperature sensor in the product, and service assistance should be summoned. The product will in the meantime attempt to maintain the set temperature. If the display is showing Pr2, there is an error with the evaporator sensor. -
Page 7: Defrosting
Defrosting Defrosting is automatically performed 4 times every 24 hours, by circulating the air inside the cabinet during a forced standstill of the compressor. The defrost LED lights to indicate the defrosting cycle is running. Defrosting is automatically performed 4 times every 24 hours, by a defrost heating element. Manual defrosting: If the cabinet is operating under severe load (frequent door opening and frequent replenishment), manual defrosting can become necessary. -
