MAINTENANCE
•
Perform visual, electrical and mechanical inspections on
a regular basis. The environment and frequency of use
should determine this. However it is recommended
that checks be made at least once a year. We
recommend an Electrical Preventive Maintenance
Program as described in the National Fire Protection
Association Bulletin NFPA No. 70B: Recommended
Practice for Electrical Equipment Maintenance (www.
nfpa.org).
•
The globe and reflector should be cleaned periodically
to insure continued lighting performance. To clean,
wipe the reflector, then the globe with a clean damp
cloth. If this is not sufficient, use a mild soap or a liquid
cleaner such as Collinite NCF or Duco #7 . Do not use
an abrasive, strong alkaline, or acid cleaner. Damage to
the reflector may result.
•
Check slip ring on the connection block for electrical
continuity. Remove any surface contamination by
lightly polishing contact ring(s). Carefully bend contacts
up to form a 45 degree angle.
• Visually check for undue heating evidenced by
discoloration of wires or other components, damaged
parts, or leakage evidenced by water or corrosion in
the interior. Replace all damaged or malfunctioning
components and clean gasket seals before putting the
luminaire back into service.
• Electrically check to make sure that all connections are
clean and tight.
• Mechanically check that all parts are properly
assembled.
CAUTION
Do not pull/carry the luminaire by the wires, this
may result in damaging the wire & the wire seal.
