Delfield T14D, T20C, T40, T5, T24C manual Blast Freezing By Temperature, Haccp

The time setting (in minutes) can be modified by means of push-buttons 7 and 8.

Press push-button 3 HARDο again to return to standard display.

+38

• Start up the cycle by pressing push-button 6	. LED 5B	and push-button LEDs remain on and
LEDs 13 flash throughout the cycle.
• Internal cell temperature is shown on display 16	οC .
• Once the cycle has been started, the appliance operates initially with an air temperature below +32°F /

0°C (LED on push-button 3 HARDο flashes), then with temperatures around +32°F / 0°C (LED on push-button

+38

3 HARDο on). For example: HARD timed chilling cycle 90 minutes. First stage of 40 minutes with negative air

temperature. Second cycle stage of 50 minutes with air temperature around +32°F / 0°C.

•When the maximum chilling time has counted back to 0, the chilling cycle is completed and the appliance automatically switches to the set positive storage temperature for an indefinite interval.

•LEDs illuminate and the beep is activated when the cycle is finished (as in the temperature chilling cycle). The same applies for the storage function.

•Press push-button 6 to set the appliance to STOP status (relative LED switches off), ready for a new cycle.

IMPORTANT: During chilling or shock freezing by time it’s possible to read the evaporator temperature by pressing push button

5.6 BLAST FREEZING BY TEMPERATURE

• To select this cycle, press push-button 4 0ο (relative LED lights up), then press push-button 5 to

select the temperature mode (LED 5A on). Insert the core probe into the core of the product to be chilled.

• Start up the cycle by pressing push-button 6 . LED 5A and those relative to the pushbuttons pressed

illuminate throughout the cycle, while LEDs 13 flash.

•The appliance proceeds to operate in the same way as that described for the positive chilling cycle. During this cycle the compressor operates in continuous mode to enable the appliance to reach the cycle end temperature in the shortest time possible (default temperature at product core is set at 0°F / -18°C). Maximum freezing time is 240 minutes.

•The alarm (ALL 14) for excessively-long freezing and conservation functions cut in with relative indicators in the same way as for timed Soft blast chilling. The factory setting for negative storage temperature is -13°F / -25°C.

•LEDs illuminate and the beep is activated when the cycle is finished (as in the soft chilling cycle by temperature). The same applies for the storage function.

Press push-button 6 to set the appliance to STOP status (relative LED switches off), ready for a new cycle.

IMPORTANT: During chilling or shock freezing by core sensor it’s possible to read:
