1. USE OF THE CONTROL PANEL
1.1 IMPORTANT
Stop of the unit does not cut the power supply to the appliance.
If the appliance is not to be used for a period of time, power must be cut off with the
insulation switch located on the control panel’s side, the plug or the disconnector because of
the risk of dammaging the refrigerating equipment.

1.3 GENERAL RECOMMENDATIONS
1.3.1 DEFROST, PREFUNCTION CYCLE
Before loading products, a prefunction cycle should be launched in order to cool the
interior of the appliance. It can be launched automatically when the appliance is powered up,
by modifying the factory settings (see ‘instructions’).
Each prefunction cycle is automatically preceded by a defrost cycle. If needed, this
function can be stopped (see paragraph 1.6 ‘special settings’)
During the defrost and/or the prefunction cycle, the display indicates the ambient
temperature of the appliance. Defrost is made with a weak ventilation (except for MI3). It can
be made with a strong ventilation by modifying the factory settings (see ‘instructions’).
After loading products into the appliance, choosing the chilling cycle at the closing of the
door can be made compulsory by modifying the factory parameters (see ‘instructions’)
1.3.2 CYCLE WITH CORE PROBE
It is recommended to use the core probe whenever it is possible because it
automatically controls the cycle. The 5 points core probe allows to read the hotest point at the
heart of the product. The cycle ends when the hotest sensor reaches the required
temperature (factory settings : +10°C in chilling mode and –18°C in freezing mode, which can
be modified case by case). The display alternately indicates the temperature at the heart of
the product and the remaining duration of the cycle.
With the factory settings, a core probe insertion test indicates that the probe is not used
for a hot product (sound alarm and the indication ‘SP’ is displayed)
1.3.3 CYCLE WITH TIMER
When the use of the core probe is impossible, a cycle with timer is possible (factory
settings : 2 hours in chilling mode and 4h30 in freezing mode. This can be modified case by
case). The cycle programming time depends on the type and the quantity of food to be
cooled. During the cycle the display indicates the remaining duration.
1.3.4 VENTILATION (except for MI3)
To avoid water spattering on the products, the ventilation power is automatically
controlled by the temperature of the appliance, with a factory level pre set at 12°C.
1.3.5 "FRAGILE PRODUCTS" FUNCTION
In some cases, in blast chilling cycle, it is possible to refrigerate the products avoiding
frost deposit (anti-freezing function). This function should only be used for reduced quantities
of products. After selecting the chilling cycle with core probe or with timer, press "Fragile
Products" key. In this case, the cycle will operate following the factory settings, with an air
temperature superior to -15°C with a strong ventilation. This can be modified case by case
whenever it is needed, for example, a weak ventilation can be applied for light products
(except for MI3) (see paragraph 1.6 ‘Special settings’)
1.3.6 PRESERVATION AFTER THE CYCLE
At the end of each cycle, the appliance programs automatically the preservation to a
temperature of +3°C for a chilling cycle with a weak ventilation (except for MI3), or to a
temperature of –18°C for a freezing cycle. The display indicates the ambient temperature.
The storage duration inside the appliance can be unlimited thanks to an automatic control of
the defrost during the preservation cycle.

2. USE
2.1 GENERAL REQUIREMENTS
Do not load products in a way that obstructs the air circulation, this is important to
ensure even distribution of cold air within the cavity.
When the probe is not used, it must be located absolutely on its support.
When the appliance is not used, it is recommended to let the door half-open.
2.2 LOADING
A space of at least 15 mm is required between each item to allow refrigerated air
to pass around the products.
The chilling or freezing time depends on the weight, nature and thickness of the
food, therefore it is difficult to accurately define a loading capacity.
2.3 CORE PROBE POSITION
The core probe must be introduced as deep as possible in the product to be
cooled.
2.4 VENTILATION
To guaranty refrigerating performance, take care the fans grids and the funnel for
air outlet have not been blocked up.
2.6 DEFROST WATER EVACUATION
Check that nothing blocks up the evacuation hole located at the bottom of the
tank in front of the evaporator.
It is necessary to empty the defrost water collection tray located under the
appliance once per day.

User Manual n°648261 – Page 12
3. MAINTENANCE IMPORTANT
Before any cleaning operation,
ensure that the appliance is unplugged.
Do not use a spray hose in order
to avoid water spattering
3.1 STAINLESS STEEL
Use warm soapy water or a non corrosive cleaner (such as Teepol or an
equivalent product) then rinse thoroughly and dry.
Do not use abrasive, aggressive or concentrated cleaning products.
Do not use wire wool under any circumstances. Fingerprints can be removed with a
cloth soaked in alcohol.
3.2 INTERIOR LINING
This should be cleaned daily.
To ease a complete cleaning, it is possible to dismantle the interior fittings.
1) Unhook the shelves runners c
2) Unhook the slides supports d
3) Unscrew the slides supports pins eand remove the
braces f
4) Unscrew the braces pins g
Do the opposite for the reassembly
To obtain a 600x400 (euronorm) interior lining, fix the slides supports pins e
directly in the interior lining without the braces pins gand the braces f.
3.3 REGULAR CLEANING.
The door seals can be removed easily for cleaning.
To ensure that the refrigeration system continues to operate properly and
provides long and reliable service the condenser must be cleaned every 3 to 6
months. This work should be undertaken by a refrigeration engineer (see instructions).
