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.
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.
When investigating power supply faults it is important to check that
all voltages are within the operating range (18 – 30 V) of the Dräger
Flame 3000 under full load conditions.
Contact Dräger if the symptom remains after all remedy actions have
been attempted, or if the symptom is not described.
