3 INSTALLATION
CAUTION
Please observe the following to ensure that the
C6097 is not damaged during installation and
operation:
– Dropping the device can cause permanent
damage. In this event, replace the entire device
and associated modules before use.
– Use approved sealing material only.
– Continuous operation with gases containing
more than 0.1%-by-vol. H
2
S or ozone
concentrations exceeding 200µg/m
3
accelerate
the ageing of elastomer materials and reduce
the service life.
– Check max. ambient temperature– see page
6 (9 Technical data).
– When using silicone tubes, only use silicone
tubes which have been sufficiently cured.
– Vapours containing silicone can adversely affect
the functioning of electrical contacts.
– Condensation or vapours containing silicone
must not be allowed to get into the housing. At
subzero temperatures, malfunctions/failures due
to icing can occur.
– When installing outdoors, place the C6097 in a
roofed area and protect from direct sunlight
(even IP65 version).
– Avoid strong impact on the unit.
– In case of highly fluctuating pressures, install a
damping nozzle/restrictor orifice.
Installation position
➔ Installation position as required, preferably with
vertical diaphragm. Then the switching point p
S
corresponds to the scale value SK set on the
hand wheel. In other installation positions, the
switching pointp
S
will change and no longer cor-
respond to the scale valueSK set on the hand
wheel. Check the switching point.

= SK p
s
= SK + 18 Pa p

= SK - 18 Pa
➔ The C6097 must not be in contact with masonry.
Minimum clearance 25mm (1").
➔ Ensure that there is sufficient installation space.
➔ Ensure unobstructed view of the hand wheel.
1
Disconnect the system from the electrical power
supply.
2
Close the gas supply.
3
Ensure that the pipeline is clean.

Seal the ports that are not in use.
CAUTION
Ports 3 and 4 are connected to the upper dia-
phragm chamber with the micro switch. For this
reason, pipes carrying gas must not be connected
to port 3 or 4.
➔ A filter pad at port 4 protects the electrical
contacts in the C6097 from dirt particles in the
surrounding air or in the medium.
