self-sealing threads (e.g. NPT thread). For Model E-11 the sealing ring is included in delivery.

■

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

measuring point are clean and undamaged.

■

Screw in or unscrew the instrument only via the flats 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.

■

Do not torque the process connector with a force greater than 50 Nm / 442 lbf.

■

Be sure to install the system to meet NEC/CEC requirements.
