BM Evolution freezers are Class A devices within the meaning of the EMC Directive.
In order to minimize energy consumption and reach announced performances, place the unit in a well-ventilated room,
away from sources of heat (radiator, heating ...) and avoid direct exposure to the sun. Place it on a flat surface. It is
essential for its proper functioning that the device is level. If necessary, use rigid shims.
It is important to ensure that no obstacle (wall, switchgear) interferes with the ventilation of the appliance (air inlet and
outlet). Remove about 200mm from each side of the freezer.
Lower the 2 front levelling feet, by performing an additional ¼ turn after contact with the ground.
The temperature of the room must not exceed + 35 ° C. The moisture content in the air should ideally not exceed 50%
RH. The use of air conditioning can significantly extend the life of compressors.
If you are using a liquid CO2or LN2liquid backup device, refer to the safety data sheets at the end of this manual.
4.3 POWER SUPPLY
See the manufacturer’s plate at the rear of the unit. 3 models are available:
-Voltage 230V ~ +/-10%, 50 Hz, protected by aM 12 A fuse.
-Voltage 110V ~ +/-10%, 50/60 Hz, protected by aM 20 A fuse.
-Voltage 220V ~ +/-10%, 60Hz, protected by aM 12 A fuse.
For voltage 220V ~ +/-10%, 60 Hz, refer to the characteristics of the voltage 230V ~ +/-10% 50 Hz in the previous table.
The connectors of the device (USB, serial port) must be connected to circuits rated S.E.L.V., according to standard IEC
61010-1: 2010.
4.4 TEMPERATURE RANGE
The BM ULT Freezer is factory set to optimise its power consumption.
On the -86°C model, the set point can be adjusted from -55°C to -90°C. The default setting is -80°C.
On the -45°C model, the set point can be adjusted from -20°C to -45°C. The default setting is -45°C.
The ambient temperature (recommended between +18°C and +35°C, ideally between 20°C and 25°C) also has a
significant impact on the power consumption of the equipment.
4.5 CONSTRUCTION AND INSULATION
The one-piece electro-galvanized steel exterior body is protected by an epoxy paint.
The inner tub is made of stainless steel. The thermal insulation is ensured by a set of insulating panels under vacuum /
polyurethane foam. The insulated swing door is mounted on a pivot.
The closing and sealing of the door are ensured by a progressive tightening handle.

8
Heated pressure relief valve:
The pressure relief valve allows a balance of pressures between the inside and the outside of the freezer which makes
it easier to open the door.
Frequent doors opening favours the introdution of moisture in the freezer and may induce frost formation after the air
intake tube where the valve is attached. A calibrated foam is placed into the air intake tube to limit this phenomenon.
Froilabo freezers are equipped with a heated pressure relief valve allowing a quick return to the ambient pressure inside
the enclosure, either after a door opening or after the injection of CO2or LN2, and without ice formation in the valve well.
In normal operation, this valve does not require any maintenance.
The heating element of the valve starts to heat when the temperature inside the freezer reaches -15 ° C.
However, check regularly (depending on use) that the pressure relief valve (located on the side of the device) and the
calibrated foam are working properly. Reposition it properly after cleaning.

After stopping the freezer completely, remove the valve foam to dry. Before restarting the freezer, replace the dry foam.
After CO2 or LN2 injection, it is necessary to dismantle the decompression valve and reposition the inner circular silicone
membrane properly in order to ensure the correct sealing inside of the valve.
Heating door seal:
Froilabo freezers are equipped with a heating door seal to prevent the formation of ice and thus maintain an optimal
seal of the freezer.
Refer to the "Maintenance, cleaning and decontamination" section for cleaning the door seal.
Air filter:
In order to maintain the cooling performance of the device and to preserve the compressors lifespan, an air filter is
placed in front of the condenser.
It is necessary to dust or wash this filter as frequently as necessary.
A device must never operate without a filter.
Clamping handle:
The device has a progressive tightening handle. Its double action makes it easier to open and close the door. The freezer
door can be locked thanks to the key lock located on the side of the handle.
