Specific Conditions of Use:
1. This device contains a thin wall diaphragm less than 1 mm
thick that forms a boundary between EPL Ga (process
connection) and EPL Gb (all other parts of the equipment). The
model code and datasheet are to be consulted for details of
the diaphragm material. During installation, maintenance, and
use, the environmental conditions to which the diaphragm will
be subjected shall be taken into account. The manufacturer's
instructions for installation and maintenance shall be followed
in detail to assure safety during its expected lifetime.
2. Flameproof joints are not intended for repair.
3. Non-standard paint options may cause risk from electrostatic
discharge. Avoid installations that could cause electrostatic
