8v: SOFT BLAST FREEZING AND CONSERVATION
The temperature soft blast freezing cycle and conservation cycle are distinguished by the followings three
phases:

soft blast freezing

blast freezing

conservation.
When the first phase ends the device automatically passes to the following one.
To start the cycle:
1. Make sure that the device is "on."
2. Make sure that the keyboard is not jammed and that a procedure is not in progress.
3. Press and release the BLAST FREEZING key: the LED , the LED and the LED HARD will
flash.
4. Press and release the HARD / SOFT key: the LED HARD will turn off.
5.1 If the parameter r19 is set to 0, the display will show the work setting from the blast freezing cycle; it is
also possible to plan this value through the parameter r8.
5.2 If the parameter r19 is set to 1, the display will show the end blast freezing temperature. It is possible to
set this value through the parameter r4.
5.3 Press and release the UP key or the DOWN key within 15 seconds to modify the value of the
parameter.
8vi: PRE-COOLING START
Every cycle of operation can be preceded by a pre-cooling phase.
To start the pre-cooling phase please operate in the suitable way:
1. Make sure that the device is "on."
2. Make sure that a procedure is not in progress.
3. Keep the BLAST CHILLING key pressed for 1 second: the LED will flash.
To stop the pre-cooling phase:
4. Keep the BLAST CHILLING key pressed for 1 second or start a cycle of operation.
The parameter r12 establishes the work setting from the pre-cooling phase.
When the cell temperature reaches the one established with the parameter r12 the pre-cooling phase continues,
the LED remains permanently turned on and the buzzer is activated for 1 second.
