5. Transport, packaging and storage
5.1 Transport
Check the pressure gauge for any damage that may have been caused
by transport. Obvious damage must be reported immediately.
5.2 Packaging
Do not remove packaging until just before mounting.
Keep the packaging as it will provide optimum protection during trans-
port (e.g. change in installation site, sending for repair).
5.3 Storage
Permissible conditions at the place of storage
Storage temperature: -30 ... +80 °C
Protect the instruments from moisture and dust.
6. Commissioning, operation
Installation and mechanical connection
In accordance with the general technical regulations for pressure
gauges (e.g. EN 837-2 "Selection and installation recommendations for
pressure gauges").
■
Process connection back mount (BM)
■
Protect measuring instruments from contamination, high temperature
changes and vibrations
■
air2guide Eco dierential pressure gauges are calibrated in vertical
position and should be installed in the same position to avoid loss of
class accuracy. If a dierent installation position is required please
specify when ordering. Gauges with high pressure ranges can
be installed in dierent non-vertical mounting position, by simply
adjusting the zero point.

Commissioning
■
During the commissioning process pressure surges must be avoided
at all costs
■
Install the pressure connection according to the symbols
⊕ high pressure ⊖ low pressure
■
Use the pressure gauge only if the diaphragm is undamaged and if it
is in perfect condition with regard to safety.
Option screw built-in variant
After tting the measuring element into the case
it can be moved in a clockwise and counter-
clockwise direction respectively for 15 angular
degrees in order to ensure precise horizontal
positioning of the instrument.
