WARNING!
Physical injuries and damage to property and the
environment caused by media escaping under high
pressure
With the pressurisation of the product, as a result of poor
sealing of the connections, media under high pressure can
escape.
Due to the high energy of the media that can escape in
the event of a failure, the possibility of physical injuries and
damage to property exists.
▶
The sealing of the connections must be carried out expertly
and checked for leak tightness.
WARNING!
Physical injuries and damage to property and the
environment caused by improper handling.
Incorrect opening or closing of a valve can lead to the
escape of media.
▶
The operator must be aware of the consequences prior to
changing the state to a specific valve position.
