MAINTAINING FLUORESCENT LAMPS
Fluorescent lamps should not be allowed to
run to failure . If a re-lamp schedule is not in
place, the tubes should be inspected for signs
of degradation (blackened ends) . Degraded or
failed tubes should be replaced .
Allowing severely degraded lamps to operate
may cause a ballast failure or could expose
the lamp holder to excessive heat . Replacing
degraded bulbs is more cost effective than
replacing ballast and lamp-holders .
Traditional re-lamp programs are 18- to 24-
month intervals . In the absence of a re-lamp
program, a yearly inspection of the lightning
system is recommended .
1 . Inspect all lamp sockets and plug–
receptacle connections for signs of arcing .
Replace any component that shows signs
of arcing .
2 . Make sure all unused receptacles have
their close-off covers securely installed .
3 . Make sure proper cleaning procedures
are followed . Lights and fans MUST be
turned off when a case is cleaned and
MUST be allowed to dry before turning
power back on .
4 . Do not use a pressure nozzle to clean
inside a case .
CLEANING STAINLESS STEEL RAILS
Use non-abrasive tools, and always polish with
grain of the steel .
Use alkaline chlorinated or non-chlorine
containing cleaners . Do not use cleaners
containing salts as this may cause pitting and
rusting of the stainless steel finish .
Clean frequently to avoid build-up of
hard, stubborn stains . Rinse and wipe
dry immediately after cleaning . Never use
hydrochloric acid (muratic acid) on stainless
steel .
CLEANING UNDER MERCHANDISERS
Remove splashguards not sealed to floor .
Use a vacuum with a long wand attachment
to remove accumulated dust and debris from
under the merchandiser .
REMOVING SCRATCHES FROM
BUMPER
Most scratches and dings can be removed
using the following procedure .
1 . Use steel wool to smooth out the surface
area of the bumper .
2 . Clean area .
3 . Apply vinyl or car wax and polish surface
for a smooth glossy finish .
