6.1 Safety precautions
Carefully read the instructions provided in chapter
"I. SAFETY PRECAUTIONS" on page 33.
6.2 Emissions
Vibrations
Under conditions of use that comply with the instructions for
correct use provided in this manual, any detected vibrations
do not give rise to dangerous situations.
Sound emissions
The noise level emitted by the machine is on average lower
than 70 dB; therefore, there is no obligation to use personal
protective equipment for the auditory system.
If the machine emits any unusual sounds, the Technician
mustbenotied.
Electromagnetic environment
The machine is designed to work properly in any industrial
electromagnetic environment, falling within the Emission and
Immunity limits provided by current standards.
6.3 Turning the machine on and off
During the machine's heating-up phase (which
varies depending on the model), the negative pres-
sure valve will release steam for a few seconds un-
til the valve closes.
If the machine is inactive for longer than a week,
the Technician must replace 100% of the water in-
side the hydraulic circuits.
Before turning the machine on, proceed as follows:
• Openthewatervalveofthewatermainsandsoftener.
• Make sure that the level of water in the heating unit is
higher than the minimum level indicated on the water
level window (1).
The level window is replaced with a green indicator
light (2) in some versions: when lit, it indicates the
correct water level in the heating unit and when it
ashes slowly, it indicates that the water is being loaded.
