6.8.1 Safety valve (overpressure protection)
Risk of explosions
DANGER!
Risk of injury by explosions!
Explosions can cause severe injuries!
Therefore:
– Install the safety valve as instructed. Observe
the manufacturer's instructions.
– Only use the safety valve for its intended
purpose.
– Never block the safety valve.
The German accident prevention regulations require a non-
lockable safety valve to be installed after the VacuStar W at the
pressure side. This valve must be selected such that it prevents
the pressure to exceed the highest permissible operating pressure
by more than 10 %. It must be identified with a TÜV component
test number and be equipped with a manual venting element.
ATTENTION!
The safety valve (overpressure protection) must be
chosen to match the maximum permitted operating
pressure, the volume flow and the temperature
range.
Assembly
1.
Install the safety valve directly downstream of the
VacuStar W.
2.
Set the safety valve to the max. permissible operating
pressure, see Tab. 2: Operating data, observe drive type.
3.
Protect the settings against unauthorised or erroneous
changes.
