4.5 Performance and ambient temperature
The BM freezer is factory set to optimise its electricity consumption.
On the -86°C model, the setpoint can be adjusted from -55°C to -87°C. The default setting is -80°C.
On the -45°C model, the setpoint can be adjusted from -20°C to -45°C. The default setting is -45°C.
The ambient temperature (between +18°C and +35°C, ideally between 23°C and 25°C) also has a significant impact on
the electricity consumption of the equipment.

Original manual –Iss. 0.1 User manual –BM 3E Freezer 11/ 44
5. Installation
5.1 Delivery - Unpacking
Use a pallet truck to move the freezer on its pallet. The freezer must be supported during unpacking to avoid any risk
of toppling. The unit may be placed on the floor and manoeuvred on casters. Once the unit has been placed in the
desired location, remove the protective plastic film and chocks.
Froilabo freezers are delivered on a pallet with an unloading ramp. This means that no special equipment is required
to unload them from the pallet. Please refer to the handling and unpacking sheet affixed to the unit.
Do not use sharp objects as they might damage the paintwork.
Note: After unpacking, inspect (if possible with the carrier present) the condition of the unit and its accessories. If any
transport damage is observed, state the details on the delivery note and inform Froilabo without delay.
After receipt, please check the items delivered:
BM 3E –340 litres
BM 3E –515 litres
BM 3E –690 litres
1 non-detachable electrical power lead
1 filter cassette
1 set of two keys
1 pressure relief valve + filters
1 manual
1 shelf
2 shelves
3 shelves
2 brackets
4 brackets
6 brackets
5.2 Environment conditions
The freezer is designed for use under the following ambient conditions (in accordance with EN 61010-1):
Indoor use
Maximum altitude: 2000 m
Ambient temperature range between 5°C and 40°C
Maximum relative humidity of 80% for temperatures up to 22°C
Supply voltage ripple < ±10 % of rated voltage.
Supply network voltage surges: category II (Standard IEC 60364-4-44)
Maximum level of room contamination: 2
BM 3E freezers are Class A devices within the meaning of the EMC Directive.
5.3 Electrical environment
A 230 V / 50 Hz or 120 V / 60 Hz single-phase electrical power supply is required, as specified on the manufacturer’s
plate at the rear of the unit.
The freezer must be powered via a safety mechanism, such as a correctly rated differential circuit breaker, which
automatically cuts off the power supply if an insulation fault occurs.
To enable the unit to be electrically cut off, the circuit breaker must be readily identifiable and within reach of the
operator.
5.4 Location
To minimise power consumption and achieve the specified performance, place the freezer in a ventilated location,
away from sources of heat (radiators, heaters, etc.) and avoid locations exposed to sunlight. Place it on a flat surface.
For correct operation, it is essential that the freezer be placed level. Use rigid chocks if necessary.
Ensure that there are no obstacles (walls, equipment) that impede the ventilation of the freezer (air inlet and outlet).
Lower the two front legs, turning by an additional quarter-turn after they touch the ground.

Original manual –Iss. 0.1 User manual –BM 3E Freezer 12/ 44
Room temperature should not exceed 35°C. The moisture content in the air must not exceed 50% RH. The use of an
air conditioning system can considerably extend the service life of the compressors.
If backup systems using liquid CO2or nitrogen vapour injection are used, please refer to the corresponding safety data
sheets in section 13 SAFETY.
5.5 Construction and insulation
The self-contained outside casing is made from zinc electroplated steel sheet protected by epoxy paint.
The inner chamber is made from stainless steel sheet. Thermal insulation is provided by vacuum and polyurethane
foam insulating panels. The insulated swivel door is mounted on a hinge.
The door is closed and sealed by a progressive sealing handle.
5.6 Control console
The control console is located towards the top of the door. It comprises a main screen and a touch-sensitive alarm
window. The main screen is touch-sensitive only on the Evolution model.

5.7 Loading
In order to avoid any damage to the freezer and ensure that the specified technical performance is attained, the
following instructions must be followed:
-Do not place highly corrosive substances in the freezer.
-Do not place explosive or highly flammable substances in the freezer.
-Leave at least 3 cm clearance along internal walls.
-Do not pull out several shelves at once.
In order to avoid any risk of a heavily loaded freezer toppling, do not pull out several sliding shelves and/or drawers
simultaneously.
Do not under any circumstances exceed the maximum allowable load for each sliding shelf or drawer.
These freezers are not explosion-proof.
The interior surfaces of the freezer and the contents can be extremely cold (-86°C):
Protect yourself accordingly (in particular by wearing suitable gloves).
It is possible to replace a drawer with a shelf. A shelf cannot, however, be replaced with a drawer.

6. GENERAL USE
6.1 Commissioning
Follow the instructions in the correct order:
1) Install the drawers or shelves in each level.
2) Connect the freezer to a power outlet (230 V 50 Hz 16 A + neutral + earth) protected by a 30 mA differential circuit
breaker (the compressor(s) and fan will start up).
Press the On/Off button.
3) The screen displays “Froilabo” (start-up phase), then shows the temperature inside the chamber.
4) Adjust the setpoint (-45°C or -80°C by default, depending on model).
See the procedure in section 6.4 Adjusting the temperature setpoint.
5) Wait until the freezer reaches the set temperature (3 to 6 hours depending on model).
6) Load the freezer.
Note 1: The temperature in the freezer may rise if it is loaded with “hot” products. The high temperature alarm may
be triggered.
Note 2: The switch cuts off only the internal 24 V power supply required in particular for the processor and display.
The freezer is still powered as long as the power cable is connected to the mains.
Any electrical maintenance must be performed by qualified staff.
