CAUTION!

If faults cannot be eliminated by means of the measures listed above, shut down the pressure transmitter

being put back into operation inadvertently. In this case, contact the manufacturer. If a return is needed,

please follow the instructions given in chapter 10.2 "Return".

10. Dismounting, return and disposal

WARNING!

Residual media in dismounted pressure transmitters can result in a risk to persons, the environment and

equipment. Take sucient precautionary measures.

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!
