both the enclosure rear cover and body.

WARNING
Explosion hazard!
Do not use the flame detector if the rear enclosure cover cannot be screwed
onto the enclosure body by five or more full turns. The detector has insufficient
explosion protection (the flame path is too short) and using it in an explosive
atmosphere may lead to an explosion.
► If so, return the detector to Dräger for investigation/repair.
8. Fully screw the rear enclosure cover to the enclosure body. Ensure that the
O-ring is beneath the cover and that the set screw will not interfere with or
be screwed into the threads of the flame path or the O-ring. Secure the rear
enclosure cover in place with the set screw.

Commissioning and functional testing
1. Switch on the Dräger Flame 3000.
When switched on, the Dräger Flame 3000 will perform an internal test
and system initialization that takes approximately five seconds.
2. Test the Dräger Flame 3000 using a flame simulator (refer to the flame
simulator instructions for details; Dräger recommend the Dräger FS-5000).
The status LED will turn red when it detects the simulated flame.
Failure of the Dräger Flame 3000 to respond to the flame simulator should
be reported to Dräger

Troubleshooting
WARNING
Do not open the enclosure in the presence of an explosive atmosphere as it
could lead to an explosion. Ensure that the flame path of the Dräger
Flame 3000 is not damaged during installation. A damaged flame path could
lead to an explosion.
CAUTION
Only appropriately trained service personnel may open the enclosure. Incorrect
disassembly of the Dräger Flame 3000 may damage the equipment.
There are no parts within the detector assembly that are serviceable by the
user. If any fault is suspected within the detector assembly, it should be returned
to Dräger for investigation and repair.
