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 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 CO
2
or LN
2
liquid backup device, refer to the safety data sheets at the end of this manual.

OWER 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.

EMPERATURE 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 b18°C and +35°C
, ideally between 20°C and 25°C) also has a
significant impact on the power consumption of the equipment.

ONSTRUCTION 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.
