Electricity
Touching voltage carrying components can result in electric shocks, burns or death.
➤ Allow only qualified and authorized electricians or trained personnel under the supervision of a
qualified and authorized electrician to carry out work on electrical equipment according to elec‐
trical engineering regulations.
➤ Before commissioning or re-commissioning the machine, the user must ensure adequate pro‐
tection against electric shock from direct or indirect contact.
➤ Before starting any work on electrical equipment:
Switch off and lock out the power supply disconnecting device and verify the absence of any
voltage.
➤ Switch off any external power sources.
These could be connections to floating relay contacts or the electrical machine heating, for ex‐
ample.
➤ Use fuses corresponding to machine power.
➤ Check regularly that all electrical connections are tight and in proper condition.
Forces of compression
Compressed air is contained energy. Uncontrolled release of this energy can cause serious injury
or death. The following information concerns work on components that could be under pressure.
➤ Close shut-off valves or otherwise isolate the machine from the distribution network to ensure
that no compressed air can flow back into the machine.
➤ Depressurize all pressurized components and enclosures.
➤ Do not carry out welding, heat treatment or mechanical modifications on pressurized compo‐
nents (e.g. pipes and vessels) as this influences the component's resistance to pressure.
The safety of the machine is then no longer ensured.
Compressed air quality
The composition of the compressed air must be suitable for the actual application in order to pre‐
clude health and life-threatening dangers.
➤ Use appropriate systems for air treatment before using the compressed air from this machine
as breathing air and/or for the processing of food products.
➤ Use food-grade cooling oil whenever compressed air is to come into contact with food prod‐
ucts.
Spring forces
Springs under tension or compression store energy. Uncontrolled release of this energy can cause
serious injury or death.
Minimum pressure / check valves, safety relief valves and inlet valves are powerfully spring-loaded.
➤ Do not open or dismantle any valves.
Rotating components
Touching the fan wheel, the coupling or the belt drive while the machine is switched on can result
in serious injury.
➤ Do not open the enclosure while the machine is activated.
➤ Switch off and lock out the power supply disconnecting device and verify the absence of any
voltage.
