BCB US Rev.02 05-2021 pag. 24
7 – USE
IN R449A APPLIANCES THERE IS A COMPRESSOR OIL HEATER, ONCE THE MACHINE FIRST
STARTS THE STANDBY MODE (MAIN SWITCH ON AND LED BOARD OFF), IT IS NECESSARY
TO WAIT AT LEAST 2 HOURS BEFORE STARTING A BLAST CHILLING CYCLE.
7.1 – USE FORSEEN
Blast chillers are appliances with a powerful refrigeration system that can rapidly reduce the temperature at the core of
food. Ideal for use in kitchens, bakeries and ice cream establishments.
The machine’s main work cycles are CHILLING and FREEZING. Each cycle includes two different end of cycle modes at
the point at which holding commences: temperature controlled (the probe inserted into the core of the product ends the
cycle when it reaches the set temperature) or time controlled (the cycle ends as soon as the set time expires).
- SOFT CHILLING. Positive “delicate” temperature reduction (+37°F). Food just out of the oven is quickly taken to
a temperature of 37°F in no longer than 90’, thus inhibiting bacterial proliferation and avoiding dehydration of the
cooked food due to evaporation. Food treated in this way can be preserved perfectly for 5-7 days without altering
its original qualities.
- HARD CHILLING. Positive “rapid” temperature reduction (+37°F). Also lasts for a maximum of 90’. This type
of process is used when the food to be chilled is thicker than an inch (i.e. large joints) and with dense or fatty
food. During this phase the appliance reaches -4°F air temperature and provides to accelerate penetration of
the cold into the food.
- FREEZING. Deep freezing or freezing (0°F). During this phase the appliance reaches -40°F air temperature.
This work cycle will take the core of the food to a temperature of 0°F in less than four hours (240’). The speed of
the process avoids the formation of macrocrystals, ensuring that when it is used the thawed food has its original
consistency, colour and quality.
- HOLDING. At the end of both the chilling and freezing cycles the machine will automatically go to the set holding
temperature.
7.2 – UNFORSEEN USE
Blast chillers cannot be used for purposes other than those described in point 7.1. In particular the appliance is not suitable
for storing food for an indefinite period.

The buzzer can be silenced, whatever its cause, by pressing any button.
Whatever situation the machine is in, holding down for 3 seconds cuts OFF the circuit board.
7.5 – USE PROCEDURES
Clean the inside of the chamber before using the machine.
After installation or a prolonged idle period, it is good practice to operate the empty appliance until it reaches the set
temperature. To achieve good output from the blast chiller it is advisable to place the food inside in such a way as to assist
air circulation: do not obstruct the fan, do not stack trays on top of each other, distribute the load neatly and do not cove r
the containers with lids or cling film.
In order to avoid altering the food, it is also advisable not to overload the machine beyond the permitted load, not to use
pieces thicker than 2-3” and to limit door opening as much as possible.
Clean and sterilise the core probe before use. The probe must be placed in the centre of the largest joint or piece, taking
care that the point does not go right through the food to come into contact with the tray.
To improve the efficacy of the working cycle is recommended to perform a pre-cooling of the cell, by turning on
the machine at least 15 min before insert the product, both in killing and freezing.
When a temperature controlled cycle is selected the electronic circuit board checks the temperature read by the
chamber probe and core probe to assess correct insertion of the probe (AUTOMATIC probe identification). This
check lasts just over two minutes, at the end of which the cycle proceeds normally if the probe is properly inserted.
This check lasts just over 2 minutes, accordingly with established parameters, at the end of which the cycle
proceeds with a temperature controlled cycle if the probe is properly inserted. In this case the temperature of the
probe will be showed and the icon will remain turned on.
If the test has a negative result, after a minute of buzzer’s alarm, the display will show the icon and the cycle
will proceed with a time controlled cycle.

7.9 – SPECIAL USES
7.9.1 – PRE-CHILLING FUNCTION OR CONTINUOUS CYCLE.
If the temperature of the food to be chilled is very high (above 149°F) it is advisable to pre-chill it in the following way:
press the button for some seconds, the device will start and the led will flash. Once reached the set point (-31°F),
the led remains on and it will be possible to choose any type of cycle or load the device with the foods you have to
chill/freeze. The new selected cycle will “overwrite” the continuous cycle, without turning off the device previously.
The continuous cycle is ideal for ice-cream laboratories, as the working cycles are very frequent (HARDERING).
It is necessary to have just the room temperature as parameter. Instead time is not a parameter necessary.
7.9.2 – DEFROST
The machine evaporator is defrosted by stopping the compressor. It can be Automatic or Manual and is shown on the
display by illumination of the wording “ dEF ” first fixed then, during the drip flashing.
Automatic defrost can only take place during the holding period, at intervals of 6 hours with a duration of 15’ and the
evaporator temperature does not exceed 46°F.
Manual defrosting can be activated when the machine is on STANDBY and the evaporator temperature does not exceed
46°F, by pressing . Because on STANDBY the compressor is already off forced ventilation takes place during Manual
defrost, so it is advisable to keep the door open throughout the cycle.
7.9.3 – LONG IDLE PERIODS
Turn the machine OFF by pressing for three seconds, switch OFF the main switch, then unplug.
Clean the machine thoroughly (see paragraph 8.2) and make sure the door is left open at the end of the operation and

8.4.2– ERRORS
Errors recognized by the electronic controller are:
- “ Pr 1 ” chamber probe error. On STANDBY impedes cycle start. On Chilling or Freezing causes the cycle to
stop and the machine to go onto STANDBY. During the Holding period the cycle is not interrupted and the
compressor works cyclically to ensure maintenance of the chamber temperature. Check probe connection and
replace if necessary.
- “ Pr 2 ” core probe error. On STANDBY impedes the start of a temperature controlled cycle. On temperature
controlled Chilling or Freezing causes the machine to go to a time controlled cycle. During the Holding period it
has no effect. Check probe connection and replace if necessary.
- “ Pr 3 ” evaporator probe error. On STANDBY, Chilling or Freezing and during Holding it has no effect. If
defrost is taking place it will end by time-out.
