The values indicated under "Technical data" apply only to vertically mounted differ-
ential pressure sensors (connection nipples pointing down).
The sensor is calibrated at the factor in the vertical position. As a consequence, the
sensor must be installed in the vertical position. For horizontal installation (hous-
ing cover top or bottom), deviations occur to measured values that negate the
measured values on the certificate.
The device is considered electrical and electronic equipment for disposal in terms
of the applicable European Directive and may not be disposed of as domestic gar-
bage.
• Dispose of the device via the channels provided for this purpose.
• Comply with all local and currently applicable laws and regulations.
