Dräger Flame 3000
5 Maintenance
WARNING
Do not open the enclosure in the presence of an explosive
atmosphere as it could lead to an explosion.
Ensure that the ame path of the Dräger Flame 3000 is not
damaged during installation. A damaged ame path could lead
to an explosion.
CAUTION
Only appropriately trained service personnel may open
the enclosure. Disassembly of the Dräger Flame 3000 by
unauthorized personnel is not permitted and may damage the
equipment.
Any attempt to dismantle, remove or repair the detector assembly
by persons who are not appropriately trained service personnel will
invalidate the warranty of the Dräger Flame 3000.
There are no parts within the detector assembly that are serviceable
by the user. The only servicing requirements are to inspect and clean
the enclosure front cover window and functional test the Dräger Flame
3000. Dräger recommend that these tasks be completed every six
months.
The actual level of maintenance required is dependant on the operating
environment and the likelihood of damage or the rate of contamination
from oil, etc. It is advisable to regularly review maintenance reports and
adapt the maintenance period to the operating environment.
Periodic maintenance checks should be performed in accordance with
appropriate codes of practice or local regulations.
