Message
“OUT” message: the user must take products out and stop the storage cycle.
The machine is not designed to store products after cycles. The storage mode has a limited time 6h.
If product is not removed after cycle it could be defrosted after the maximum time.
Steps during launching a cycle:
• Freezing / chilling mode: it stops automatically when the set points are reached (clock or core probe
mode)
• Automatic storage mode after the cycle: it must be stopped manually by the user by pressing the “On / Off”
key. The purpose of this step is to maintain the products at a positive / negative temperature after a deep-
freezing / blast-chilling cycle in case the user is not near the equipment to take products out immediately.
It is not recommended to keep the equipment in storage mode. The equipment is not intended for.
• Automatic ventilated defrosting mode: it is automatically stopped after a certain time or when the
maximum temperature is reached. This mode is not activated in the case of blast chilling.

• Cycle animation
• Remaining time
If you are in “Time” mode, the LED of “Hourglass icon” is permanently green, otherwise you are in “Core
probe” mode and the LED of “Probe icon” is permanently green.
3 - DEFROSTING
3.1 Automatic defrost
A ventilated defrosting is automatically programmed at the end of a deep-freezing cycle. See section 2.1.1.
It stops automatically after a certain time or when the maximum temperature is reached.
3.2 Manual defrost
If you notice too much frost, you can start a manual defrost.
For this, make a long press on the “Enter” button.
