Standby modeON BC/BF-MODELS ONLY13D1ABy pressing the “MODE” switch [A], you can change theprogram from blast chilling (bC) to (bF) blast freezing or tocombination of blast chilling on to blast freezing in oneoperation.2 45 6Picture 6. BC modeD2D3L1 L2 L3BCThe control processor has free memory slots for the operatorto customise the process to suit their requirements i.e. smallbatches, easily chilled food that make shorter period to chillthan normal or food being enterred below +70°C and the timerequired will be less than normally recommended. There are 9available programmable memory slots (bC1 to bC9 for allmodels and bF1 to bF9 BC/BF-models). To select the requiredprogram in the memory press either arrow up switch [3] or down[4] . All the entered programs can be altered prior tocommencement of the process by pressing switch [B] or [C].Please note these changes will not be saved in the memory.When chilling delicate foods that can be easily damaged orfrozen i.e. whipped cream, the fan speed can be adjusted bypressing switch [B] to half speed. But please note on half speedthe process may take longer.1234D1D2ABAlso to avoid freezing of the product during blast chilling theprocesses can be controlled by using the soft/hard switch [C].When adjusted to 1 the process retarted to gentle chilling mode,selecting position 7 blast chilling is at it’s most effective.5 6Picture 7. BF modeD3L1 L2 L3CWith the cabinet set to [bC] mode the chilling program can becontrolled by the actual food temperature or, as all the otherprocesses, by time. If you select to chill by food temperature theprobe must be inserted in to the food prior to starting the blastchilling program. When the food reaches selected temperaturethe processis complete and the room will revert to a normalholding mode. The actual product temperature is shown on thedisplay D2, while D3 shows the set point temperature.Once the selected program is activated by the start/stopswitch, then settings can not be alternated unless the processis stopped. After the program has ended (rdy), the fi rst defrostcycle starts after which the control unit automatically transfers tothe normal holding mode and the cabinet can be used totemporarily storing of cold/frozen products.Note: do not add warm foods when the cabinet is in holdingmode.6
