for ecient and trouble-free operation.
2. Safety
WARNING!
Before installation, commissioning and operation, ensure
that the appropriate pressure gauge has been selected in
terms of measuring range, design and specic measuring
conditions.
Non-observance can result in serious injury and/or damage
to the equipment.
Further important safety instructions can be found in the
individual chapters of these operating instructions.
2.1 Intended use
This pressure gauge is designed for measuring very low pressures in
dry, clean, non-aggressive gases, primarily air.
The instrument has been designed and built solely for the intended use
described here, and may only be used accordingly.
The manufacturer shall not be liable for claims of any type based on
operation contrary to the intended use.

5. Transport, packaging ... / 6. Commissioning, operation
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 dierential pressure gauges are calibrated in vertical
position and should be installed in the same position to avoid loss of
class accuracy. If a dierent installation position is required please
specify when ordering. Gauges with high pressure ranges can
be installed in dierent non-vertical mounting position, by simply
adjusting the zero point.

6. Commissioning, operation
Panel mounting
1. Fasten the mounting ring using the supplied
three screws.
2. Insert the measuring instrument into the
mounting ring.
3.Turn the measuring instrument clockwise
or anti-clockwise, until an exactly horizontal

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.
