CLEANING AMBIENT AIR FILTER
For proper refrigeration performance, the ambient
air filters should be cleaned or replaced at least
every six months. The filters are located on top of
the case and measure 36 x 4 x
1
/
4
inches (914 x 102
x 6.4 mm). There are two filters in an 8 ft
(2438 mm) case, three filters in a 12 ft (3658 mm)
case, and one filter in a 4 or 6 ft (1219 or
1829 mm) case.
The metal mesh filter can be lifted out without
tools. If preferred, the filter and its frame can be
removed together by removing sheetmetal screws
holding the frame. Gently shake the filter to
remove loose debris, then wash the filter with soap
and hot water. Allow to dry completely before re-
installing.
Replacement filters should be UL Class II type
filters.
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 or top rail.
2. Clean area.
3. Apply vinyl or car wax and polish surface for
a smooth glossy finish.
CLEANING HONEYCOMB ASSEMBLIES
Honeycombs should be cleaned every six months.
Dirty honeycombs will cause merchandisers to
perform poorly. The honeycombs may be cleaned
with a vacuum cleaner. Soap and water may be
used if the honeycomb is removed from the case.
Damaged honeycombs should be replaced.
