After mounting, set the compensating valve (if available)
from CLOSE to OPEN.
In order to avoid any additional heating, the instruments must not be exposed
to direct solar irradiation while in operation!
Admissible ambient and working temperatures
When mounting the pressure gauge it must be ensured that, taking into
consideration the influence of convection and heat radiation, no deviation above
or below the permissible ambient and medium temperatures can occur. The
influence of temperature on the display accuracy must be observed.
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
by installing a flexible connection line between the measuring point and the
pressure gauge and mounting the instrument on a suitable bracket.
Liquid-filled gauges (model 633.50) may only be used within the following
limits:
Frequency range < 150 Hz and
Acceleration < 0.5 g (5 m/s
The liquid filling must be checked on a regular basis.
The liquid level must not drop below 75 % of the gauge diameter.
Commissioning
During the commissioning process pressure surges must be avoided at all costs.
Open the shut-off valves slowly.
