Risk of bursting in pressure equipment.
The valve and pressure element are pressure
equipment. Improper opening can lead to
bursting of the parts. In the installed state,
the spring in the operating element is pre -
loaded. Incorrect dismantling will release a
high amount of energy, which may lead to
serious injury.
− Do not dismantle the device.

support concerning maintenance or repair
work or when malfunctions or defects
arise.
