Cleaning the Enclosure
The enclosure should be cleaned periodically with a
damp cloth to maintain maximum light output. The
polycarbonate colored LED lens should be regularly
inspected for cracks. If it is damaged, it must be replaced.
Refer to the “Certification” section for any applicable
Specific Conditions of Use.
Replacing the LED Array
EXPLOSION HAZARD: To maintain the flameproof
integrity of the enclosure, DO NOT damage the lens
cover or threads while disassembling or reassembling
the beacon.
LIGHT HAZARD: To be an effective warning device, the
beacon produces bright light that can be hazardous to
your eyesight when viewed at close range. Do not stare
directly into the beacon at close range, or permanent
damage to your eyesight may occur.
BURN HAZARD: The LED array gets hot enough to burn
you. Always allow the array to cool before handling it.
STATIC SENSITIVE DEVICE: The circuitry of the beacon
can be damaged by an electrostatic discharge (ESD).
Always follow anti-static procedures while servicing the
beacon.
