4. First contact with your freezer
4.1 Delivery and unpacking
Use a pallet truck to move the freezer on its pallet. It is imperative to keep the freezer unpacked to avoid any risk of
tipping over. The device can be placed on the ground and maneuvered thanks to the wheels. After positioning the device
in the desired location, remove the various protective plastics and shims.
Do not forget to remove the foam padding shelves (at the bottom thereof) to avoid damaging the gates when closing
the door once the freezer is at -80 ° C.
Froilabo freezers are delivered on a pallet equipped with an unloading ramp. In fact, they do not require specific
equipment to get off the pallet. Please refer to the handling and unpacking sheet attached to the device.
After the reception, please check the contents of the delivery.
Do not use sharp objects to avoid damaging the paint. Do not tip the device. Preserve the device as much
as possible from all vibrations. Two people are needed to move the device.
Protective gloves should always be worn!

4.2 Implantation and installation
The freezer is designed for use under the following environmental conditions (according to EN 61010-1):
•Indoor use only
•Maximum altitude: 2000 m
•Ambient temperature range of 18 ° C to 32 ° 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
TRUST freezers are Class A devices within the meaning of the EMC Directive.
In order to minimize energy consumption and granted annonced 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 CO
2
or LN
2
liquid backup device, refer to the safety data sheets at the end of this manual.
4.3 Power supply
See the manufacturer's plate on the back of the device, 3 models exist:
-Tension 230V ~ +/-10%, 50 Hz, protection par fusible "aM 12 A"
-Tension 110V ~ +/-10%, 50/60Hz, protection par fusible "aM 20 A"
-Tension 220V ~ +/-10%, 60Hz, protection par fusible "aM 12 A"
For the voltage 220V ~ +/- 10% 60 Hz, refer to the characteristics of the voltage 230V ~ +/- 10% 50 Hz of the table in §
4.6.
The power supply must be single-phase, in accordance with the manufacturer's plate on the rear of the unit. It must be
equipped with a safety device ensuring the automatic shutdown of the power supply in the event of an insulation fault,
such as a properly sized differential circuit breaker.
In order to allow the electrical disconnection of the appliance, the circuit breaker must be immediately identifiable and
within easy reach of the operator
Your freezer is equipped with a detachable IEC connector with blocking.
The insertion of the male connector into the female connector (step a) is carried out
normally.
To remove the IEC connector (step c), slide the red pull tab back to allow the male
connector to be removed from the female connector.

4.4 Temperature range
The TRUST freezer is factory preset to optimized power consumption.
On the-86°C model, the setting ranges from -55°C to - 90°C, default setting being -80°C.
On the -45°C model, the setting ranges from -20°C to -45°C, default setting being-45°C.
The ambient temperature (recommanded between +18°C and +32°C, ideally between 20°C and 25°C) has a major
influence on the power consumption of the equipment.
4.5 Construction and isolation
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 is ensured by a progressive tightening handle.

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 promotes the introdution of moisture in the freezer and may induce frost formation after the air
intake tube to which 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 CO
2
or LN
2
, and that without ice formation in
the valve well.
In normal operation, this vlave 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 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 tha handle.
