10.1 Dismounting
WARNING!
Risk of burns!
Let the instrument cool down suciently before dismounting!
During dismounting there is a risk of dangerously hot pressure media escaping.
When removing the instrument, the force required to do this must not be applied through the case or the cap ring, but
only through the spanner ats provided for this purpose and using a suitable tool (see chapter 6.1.2 "Installing the
instrument").
When there is a cooling element, the lower hexagon should be used for unscrewing (see chapter 6.1.2 "Installing the
instrument")
Only disconnect the pressure transmitter once the system has been depressurised!
