6.7 Safety equipment
The following safety equipment must be installed:
Safety valve
Monitoring the compression end temperature
Non-return valve always at the suction side
Vacuum suction filter
Protection against contact.
6.7.1 Safety valve
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 WR 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.
Assembly
1. Install the safety valve immediately after the pressure pipe
joint.
2. The nominal opening pressure may not exceed the maximum
permissible final overpressure (refer to Tab. 2) or the
permissible system pressure, provided the latter is lower.
