Risk of injury due to leaking medium
Inflammatory, irritating and harmful substances can escape from the gauge and lead to
skin injuries and burns. This danger is also to be expected in the case of an unpressurised
cooled system.
•
Wear protective clothing including safety glasses.
•
Check the danger posed by the medium and, if necessary, wear respiratory
protection or support.
•
Observe the order of work.
•
Perform work only when the gauge is depressurized and emptied.
•
In principle, do not consider any system to be depressurised.
8.1 Before commissioning
Torque
All valves are pressure tested before delivery. In individual cases, material settlement can
occur due to transport, long-term storage or during assembly. All screw connections must
therefore be checked for tightness and appropriate torque.

Leaks due to insufficient torques
•
Check screw connections for appropriate torque and a tight fit.
•
24 hours after commissioning, check all screw connections again for the correct
torque and possibly retighten.
•
Check for leaks in the first few days after commissioning

Property damage caused by contaminated medium
Impurities in the medium can cause leaks during commissioning and possible subsequent
flushing.
