Operating environment temperature
Temperature of the environment with the ma-
chine off (e.g., storage, transport, etc.)
Thanks to its modularity, each machine is able to adapt to different needs in terms of air flow
and thermodynamic treatments.
The optimised choice of every detail, the search for maximum efficiency in each
component, the adoption of specific materials and constructive solutions transform
environment friendliness and energy savings into valid and advanced technological solutions.
+5°C to +46°C
-40°C to +60°C
Environmental contamination
Depending on the installation operating environment, specific regulations must be followed and all the
necessary precautions must be taken to avoid environmental issues (a system that operates in a hospital
or chemical environment can have problems different from those in other sectors, even from the point of
view of disposal of consumable parts, filters, etc.).
It is mandatory for the buyer to inform and train workers regarding proper procedures.
Noise
The machines have been designed and manufactured in such a way as to produce sound
> 80 dB(A)
during the machine's actual use.
10
emissions below the threshold of 80 dB(A). It should be noted that every environment has
its own acoustic characteristics that can greatly affect the noise perceived during operation,
therefore it is necessary to consider the noise data provided as a point of reference, while it
is up to the buyer to perform specific sound level measurements at the installation site and
Ceiling and air duct specifications
The ceiling where you plan to install the machine must be:
- Perfectly flat and without roughness.
- Vibration resistant.
- Able to support the weight of the equipment considering an appropriate safety margin (see table of technical data on page
12).
The equipment installed on the ceiling can adapt easily to the presence of a false ceiling.
In fact, without sufficient space for up-and-over door opening, the inspection door can be transformed
into a panel able to slide on accessory rails (optional)
If provided, the air ducts must be connected directly to the machine, taking care to insert a suitable
anti-vibration system between the machine itself and the duct. When assembly is completed they must
not be taut, in order to avoid damage and transmission of vibrations.
To ensure the seal of the connections and the integrity of the machine, it is essential that the air ducts be
supported by special brackets that do not weigh directly on the machine.
