4.1 Intended purpose
The compressed air counter is intended exclusively for use in pipe systems
for working compressed air, provided that the calibration certificate does not
explicitly allow using for other gases.
Thanks to the design, operation in systems that are under pressure up to
PN16 is possible.
The system must be depressurized before beginning the drilling and welding
work.
0699 6446: Before assembling or dismantling the sensor or the sealing cap
(available as an accessory), the system status must be at zero pressure.
Use which deviates from that described endangers the safety of people and
of all of the measuring equipment and is thus not permissible.
The manufacturer accepts no liability for damages that occur as a result of
improper or inappropriate use or installation.
To avoid damage to the instrument or health hazards, no manipulation using
tools may occur on the measuring units that is not expressly defined in this
operating manual.
0699 6446: Changing the sensors while in operation is not possible.
0699 6447: If all necessary operation steps are observed, changing the elec-
tronic sensor assembly while in operation is possible thanks to the inter-
changeable fitting.
The compressed air counter may only be operated under the ambient condi-
tions specified in the technical data. Otherwise, inaccurate measurements
occur or instrument malfunctions become possible.
To ensure the safety of the user and the operability of the instruments, the
commissioning steps, checks and maintenance work recommended by the
manufacturer are to be complied with and carried out.
These instructions do not contain complete detailed information for the sake
of transparency.
Should you require further information or should a specific problem occur
that is not comprehensively handled in the instructions, you can request the
required information directly from the manufacturer.
Read these operating instructions before commissioning the fitting. Store
these operating instructions in a location that is accessible for all users at all
times. Please support us in improving these operating instructions. We are
grateful for any ideas you may have.
