CAUTION!
Prior to commissioning, the pressure transmitter must be subjected to a visual inspection.
■ Leaking fluid is indicative of damage.
■ Only use the pressure transmitter if it is in perfect condition with respect to safety.
Making the mechanical connection
■ For model A-10 with parallel thread, the sealing ring is included in the delivery.
■ During mounting, make sure that the sealing faces at the pressure transmitter
and the measuring point are clean and undamaged.
■ Only ever screw in, or unscrew, the instrument via the spanner-flats and to
the prescribed torque using an appropriate tool. The correct torque depends
on the dimensions of the pressure connection and the gasket used (form/
material). When screwing in or unscrewing the pressure transmitter, do not
use the housing for purchase.
■ When screwing in, do not cross the threads.
