Strictly follow the Instructions for Use
Any use of the apparatus requires full understanding and strict observation of these instructions.
The apparatus is only to be used for purposes specified here.
Maintenance
The unit must be inspected and serviced regularly by suitably qualified persons.
Repair and general overhaul of the apparatus may only be carried out by trained service personnel.
We recommend that a service contract be obtained with DrägerService and that all repairs also be carried out by them.
Only authentic Dräger spare parts may be used for maintenance.
Observe chapter "Maintenance Intervals".
Use in areas subject to explosion hazards
Equipment and components which are used in explosion-hazard areas and which have been inspected and approved
in accordance with international or European explosion-protection regulations may be used only under the specified
conditions. The equipment or components may not be modified in any manner. The use of faulty or incomplete parts is
forbidden. The appropriate regulations must be observed at all times when carrying out repairs on the equipment or
components. If the transmitter has been installed with a suitable safety barrier, its case may be opened or the sensor
may be changed while the transmitter is operating.
When the transmitter is installed in Ex areas Class II, Div. 1 & 2, Group E, F, G the opening of the housing (inclusive
sensor replacement) must not be done when connected to power (power must be turned off or the area has to be
declassified). Explosion hazard!
If the transmitter is equipped, either when delivered or subsequently, with the relay module and/or the pump module,
the complete unit is no longer approved for use in explosion-hazard areas. The use of the Dräger Polytron 7000
equipped with a pump module and/or relay module in explosion-hazard areas is forbidden! Explosion hazard!
Not suitable for use in oxygen-enriched atmospheres, i.e. oxygen content exceeds 21 vol. %. Explosion hazard!
When used in transmitters with pump module, the O2 LS sensor (68 09 630) must always be installed at vibration-
free locations. If used in this combination, vibrations may cause the measured value to deviate outside of the permis-
sible range.
In applications where category 1G (Zone 0) or EPL Ga devices are required, intense electrostatic charging processes
must be avoided.
