CLEANING COILS

Condenser coils should be cleaned at least
once per month. Additional cleaning may be
needed depending on the operational environ-
ment. A dirty condenser blocks normal airflow
through the coils.
Airflow blockage increases energy consump-
tion and reduces the merchandiser's ability to
maintain operating temperature.
To clean the coils, use a vacuum cleaner with
a wand attachment and a soft (non-metallic)
brush to remove dirt and debris. Do not bend
coil fins. Always wear gloves and protective
eye wear when cleaning near sharp coil fins
and dust particles.
NEVER USE SHARP OBJECTS AROUND
COILS. Use a soft brush or vacuum brush to
clean debris from coils. Do not puncture coils!
Do not bend fins. Contact an authorized
service technician if a coil is punctured,
cracked, or otherwise damaged.
ICE in or on the coil indicates the refrigera-
tion and defrost cycle is not operating prop-
erly. Contact an authorized service technician
to determine the cause of icing, and to make
adjustments as necessary. To maintain product
integrity, move all product to a cooler until
the unit has returned to normal operating
temperatures.

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 lighting
system is recommended.
1. Inspect all lamp sockets and plug-receptacle
connections for signs of arching. Replace any
component that shows signs of arching.
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
of case.
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.
