Sign Descripon
Generic hazard warning.
Posioned near the condensaon discharge plug (if present), to warn of the possible
presence of hazardous substances and/or substances at a high temperature.
2.2 Mechanical characteriscs risks
The following is a list of specic hazards related to the fan’s mechanical characteriscs.
WARNING! Risk of personal injury.
A person may receive injuries as a result of:
• Being dragged between a moving part and a xed part, for example a impeller and the
casing or some other xed part of the fan.
• Being dragged into the fan through the air intake, with consequent contact with the
sha or impeller.
• Contact with a moving part, such as the impeller.
• Ejecon from the fan exit of fragments deriving from the introducon of residual solids
or liquids extraneous to the process, or deriving from the sucon environment.
• An object drawn into the fan mouth and ejected at high speed from the fan intake or
exit.
• Structural defects of fan components.
• Contact with fan surfaces at dangerous temperatures, for example below -20°C or higher
than +50°C.
• When working with hot uids, there may be losses of jets of hot uid from the
transmission sha hole that may cause burns or scalds.
• The potenal harmfulness of the uid being moved or the presence of substances that in
case of leaks may be hazardous (toxic and/or inammable).
• A hazard deriving from motor overspeed, which may cause the breakage of machine
parts.
• The intake of air at abnormal temperatures higher than those recommended may cause
structural deformaons, malfuncons and hazards.
2.3 Environmental risks
The fan is designed to operate in and to withstand ordinary condions of working
environments.
The presence of the following can aect the life span of components, causing premature
deterioraon, above all with respect to guards:
• Vibraons
• Corrosive agents (dust, gas, fumes, mist)
• High temperatures
• Condensaon
• Solid bodies
• Abnormal turbulence
• Currents of air
