5.3 Information about remaining risks of the equipment
Fire:
This equipment, in accordance to EN-378-2, is supplied with freon drain safety valve.
In case of fire it is preferable to use fire extinguishers or extinction systems basically composed of powder or foam or carbon dioxide: it is possible to
cool the equipment thanks to nebulized water.
Avoid the massive use of water because, in case of freon gas leak, the chemical reaction can cause caustic effects, even if small.
In any case it is necessary to cool down the ambient and/or the equipment’s temperature and before any intervention wait until the temperature has
been reduced.
Therefore it is preferable to insert this equipment into the Fire Prevention and Factory Safety Plan.
Arrange adequate actions capable to prevent and fight the possible risk.
Dispersion of freon gas in the ambient:
the refrigerant means is toxic only if inhaled at high concentration: it is necessary to provide an adequate ventilation in the room where the equipment
is installed.
In any case check the scheme showing the values and the risk sentences.
Excessive pressure on the compressed air side:
this equipment isn’t supplied with safety devices on the compressed air side.
The safety devices on the compressed air side must be carried out by the installer.
Such devices will have to be carried out according to the applicable National Norms and to the limits mentioned in this Manual.
Ozone layer deterioration:
The adoption of HFC freon reduce to the minimum ozone layer deterioration and greenhouse effect.
