Explosion protection
●
Do not operate the device in oxygen-enriched atmospheres,
otherwise the device will not be explosion-proof.
●
The device must not be stored or operated in explosive envi-
ronments if there is a chance of strong electrostatic charges
occurring (e.g. from fast moving particles, hydraulically pro-
pelled liquids, pneumatically extracted dust or materials, in
electrostatic coating processes).
Maintenance
●
Perform device inspection and adjustment only in well venti-
lated rooms or outdoors.
●
Handle test gases in a professional manner.
Sensors
●
Have sensors replaced by SEWERIN Service when their ser-
vice life has expired.
●
SEWERIN recommends: Perform a device inspection when
the device has been exposed to gas concentrations above the
end of measuring range.
Special environments
●
Substances containing silicone, and silicone vapours, can con-
taminate the sensors.
−
Do not allow the device to come into contact with substances
containing silicone.
−
Use the device only in a silicone-free environment.
●
The device complies with the requirements of Directive
2014/30/EU (EMC). When using the product close to devices
with radio transmitters:
−
Comply with the information in the operating instructions for
the devices regarding emission of interference.
●
When used in mines:
−
Use the device only in environments where there is a low
risk of mechanical impacts.
