2. Safety
WARNING!
Before installation, commissioning and operation, ensure
that the appropriate inclined tube manometer has been
selected in terms of measuring range, design and specic
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 inclined tube manometer is used for the monitoring of ventilators,
blowers and lters in air-conditioning and clean room applications 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.

4. Design and function
Description
The pressure dierential between the lower and higher pressure is
indicated by the movement of an inclined liquid column.The higher
the pressure, the more the liquid is displaced upwards. A glass tube,
which has been lled with liquid to a specic extent, is used for this. The
pressure can be easily read on the scale.
Scope of delivery
Cross-check the scope of delivery with the delivery note.
5. Transport, packaging and storage
5.1 Transport
Check the inclined tube manometer 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
transport (e.g. change in installation site, sending for repair).
5.3 Storage
Permissible conditions at the place of storage
Storage temperature: -40 ... +60 °C
Protect the instruments from moisture and dust.

6. Commissioning, operation
Installation
■
The inclined tube manometer must be screw-tted on a suitable
vertical surface
■
The instrument has to be mounted horizontally using the attached
self-tapping screws.
Filling
Turn the zero button back up until the stop. Then turn approximately one
rotation in a clockwise direction, so that the adjustment can be made in
both directions. Unscrew the ll button and ll the measuring instrument
liquid until the liquid is visible near the zero point on the measuring
scale. Make an accurate adjustment with the zero button and then
re-seal the lling hole.
Connection to the air lter
Make the hose connection between the ⊖ connection of the measuring
instrument with the downstream side of the lter and the ⊕ connection
of the measuring instrument with the upstream side of the lter. Stick
the green and red labels next to each other on the scale, in order
to mark the initial (green) and nal pressure (red). Please note the
recommendations of the plant manufacturer regarding the maximum
allowable pressure drop values.
Information
The inclined tube manometer is specially designed
to prevent leakage of the indicator uid in the case of
overpressure.
