Remove the protection cap by hand only just before installation and absolutely avoid
any damage to the diaphragm during installation as well (P3291).
For Model P3290 you have to provide for a sealing element; exceptions are instruments
with self-sealing threads (e.g. NPT thread). For Model P3291 the sealing 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.
