■

Remove the protection cap only just before installation.

■

When mounting the instrument, ensure that the sealing faces of the instrument and the

measuring point are clean and undamaged.

■

Do not scratch or nick the bead. Do not over tighten. Damage to the bead will aect the

tting's performance and may cause leakage in the system.

■

Screw in or unscrew the instrument only via the ats using a suitable tool and the prescribed

torque. The appropriate torque depends on the dimension of the pressure connection and on

the sealing element used (form/material). Do not use the case as working surface for screwing

in or unscrewing the instrument.

■

When screwing the transmitter in, ensure that the threads are not jammed.

WARNING!

For transducer with Ex-/FM-marking:

■

Protect the inner diaphragm against any contact with abrasive substances and pressure

peaks and do not touch it with tools. Damage of the diaphragm may result in losing the

explosion protection.

■

Observe the technical data for the use of the transducer in connection with aggressive /

corrosive media and for the avoidance of mechanical hazards.

Mechanical Connection

■

Prepare the gas line connections appropriately.

■

You should blow clean all tting components (such as sealing gaskets, for example) using a clean/ltered

gas. Please refer to the specic technical guides furnished by the gasket manufacturers for additional

specications.

■

You can then remove the protective lm, as well as any plastic caps there may be for protecting high-quality

ttings.
