Service Deli Merchandisers
CLEANING THE BOTTOM DECK
Remove the bottom wire racks and painted
metal bottom racks. Clean the interior surfaces
as described on Page 4-1. The merchandiser
has a 1-inch floor drain that directs the water
outside of the merchandiser.
Use a bucket or connect the drain to a hose to
remove excess water. After cleaning the inside
of the merchandiser, replace the drain caps in
order to avoid air leaks and water dripping on
the floor.
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.
Unplug merchandiser before servicing. Always
wear gloves and protective eye wear when cleaning
evaporation pan.
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.
