6. Commissioning, operation / 7. Maintenance and cleaning
Permissible vibration load at the installation site
The instruments should always be installed in locations free from vibration.
If necessary, it is possible to isolate the instrument from the mounting point, e.g. by installing
a flexible connection line between the measuring point and the instrument and mounting the
instrument on a suitable bracket.
If this is not possible, the following limit values must not be exceeded:
Frequency range < 150 Hz
Acceleration < 0.5 g (5 m/s

6.2 Commissioning

During the commissioning process pressure surges must be avoided at all costs. Open the
shut-off valves slowly.

7. Maintenance and cleaning

7.1 Maintenance

The instruments are maintenance-free. The indicator should be checked once or twice
every year. For this the instrument must be disconnected from the process to check with a
pressure testing device.
WARNING!
Danger to life due to impermissible filling/refilling of the instrument
with loss of explosion protection
The filling/refilling of instruments by non-authorised personnel leads to a loss
of the explosion protection and can lead to damage to the instrument.
▶ Repair of the instruments may only be carried out by authorised bodies.
If the instrument is exposed to intensive UV radiation, the colouring of the dial
printing may change. This has no effect on the function of the instrument.
