WARNING!
Protect the diaphragm against any contact with abrasive substances and pressure
■
peaks and do not touch it with tools.
Observe the technical data for the use of the pressure transmitter in connection
■
with aggressive / corrosive media and for the avoidance of mechanical hazards.
Remove the protection cap only just before installation and absolutely avoid any damage to
■
the diaphragm during installation as well (E-11).
For Model E-10 you have to provide for a sealing element; exceptions are instruments with
■
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.
