DANGER! The refrigerants used, although classified as "non-toxic", can cause serious problems,
such as:
Altered heart rhythm - Asphyxiation - Anaesthetising effects - Frostbite to the eyes and skin. DO NOT
USE FLUIDS OTHER THAN THOSE SPECIFIED (E.G. AMMONIA) WHICH MAY DAMAGE THE UNIT.
Potential dangers
DANGER! In the medium pressure side of the system, carbon dioxide is present in the form of
liquefied gas; contact with the liquid refrigerant can cause cold burns and frostbite. At high ambient
concentrations there may be choking hazards due to insufficient oxygen.

10. Transportation, handling and lifting (Fig. 2)

The refrigeration unit features a self-bearing steel frame for transport using a forklift truck or an overhead crane. The forks
must be 150-200 mm longer than the depth of the machine to allow for it to be lifted safely. If an overhead crane is used, it is
necessary to use a four-point sling bar.
For the weight of each refrigeration unit, see the specific technical data sheet.
On the steel frame there are plates with a yellow background that indicate the exact lifting points for the purpose of load
stability. Use a lifting fork with a suitable capacity and/or a sling that complies with the yellow lifting plates in order to avoid
transverse stresses on the structure of the refrigeration unit and to avoid damaging its components. The refrigeration unit
features temporary support feet which must not be removed until the final positioning. The feet guarantee correct support
during transportation.
Make sure that the refrigeration unit always rests on its temporary feet before final installation.
ATTENTION! DO NOT USE LIFTING POINTS OTHER THAN THOSE INDICATED.
11. Installation and environmental conditions
For the installation it is necessary to respect certain limit environmental conditions that
are:
Temperature: from -10 °C to 45 °C;
Relative humidity: from 30% to 80%;
Degree of protection: OPEN version IP30 / CLOSED version IP44.
For conditions other than those indicated, suitable packaging will be provided in the form of supplementary notes.
For the installation proceed as follows:

The refrigeration unit must be installed in rooms where the presence of personnel is not continuous.

Allow access to the room only to specialist technical personnel.

Provide enough space for immediate access to the machine.
