SECURITY
All the materials used were selected according to the UNI-CEI-EN specifications.
Thus these instruments, which received the CE marking, have reached a satisfactory degree of intrinsic safety, as long as the
users are qualified operators with knowledge of the rules for use and maintenance as exposed in this Manual, and safety devices
supplied are never misused.
There is even a ground point.
Acoustic pressure level is under 70dB.
I.P.D. ( Individual Protection Devices) - Minimum Req.'s
To avoid accidents, please follow these minimum requirements:
- Use protective gloves heat & steam-resistant.
- Use face-protecting mask to avoid possible scald injurie
Precautions
Ensure that:
- the unit is installed in a stable, horizontal position.
- the internal ventilation openings are not blocked.
- the instrument has a minimum space of 100 mm from the wall for a correct installation
- the working space has a temperature range from 5° to 40°C and the humidity range has to be between 30% and 80%.
