PLEASE NOTE!
The replacement procedure is described for one

to replace the other valves.
Comply with the operating instructions of the
component manufacturer.
 Shut down the unit, cut off the power supply with the main
switch and secure it against being switched on again
unintentionally.
 Cut off the material flows with the shut-off valves.
 Cut off the compressed air supply using the shut-off valve
WARNING!
Risk of injury from compressed air!
If there is damage or connections are leaky, air can
escape under high pressure and damage the eyes,
for example.
Therefore:
– Wear safety glasses.
– Before starting work on the pneumatic system,
render it pressureless. Check the accumulator
and relieve all pressure in it.
– Before putting the unit back into operation,
ensure that the pressure settings do not exceed
the maximum permitted values in the technical
specifications.
