7. Vibrations
The cooling unit does not produce any significant vibrations as the parts which generate them are
installed on anti-vibration devices.
8. Mechanical Parts
8.1 STRUCTURE
These machines are composed using self-supporting panels which are made of steel zinc plate
sheet and are provided with a powder coating as a protection against corrosion (suitable only in
non-corrosive and non-salty environments). They make the machine easy to inspect and, at the
same time, offer adequate protection to its internal components.
Internal components of the structure are only accessible by removing cladding panels. These are
removed by extracting their fastening screws using suitable tools. The external panels are internally
lined out with sound-absorbing material of a thickness of 10 mm, which consists of polyurethane
foam based on open cell polyester, fire-tested according to FMVSS motor vehicle safety std 302.
8.2 AIR FILTER (EU3 class)
It is designed to prevent large dirt particles present in the environment from obstructing airflow
through the evaporator.
8.3 DAMPER (only free cooling)
This mobile damper powered by a servomotor directs the inside and outside air flow.
Damper: made of galvanized steel mounted on self-lubricating bushes.
8.4 FIXING BRACKETS
Consisting of steel zinc plate sheet with a powder coating as a protection against corrosion (suitable
only in non-corrosive and non-salty environments). To fix the evaporating unit to the ceiling or the
wall, use these brackets, following instructions in chapter 12.
6. Precautions when handling the Unit
Handle these units, when they are packaged, using a fork lift. When they are not packaged use a
hoisting machine equipped with cables or chains suited for supporting their weight.
