Case Cleaning
Long life and satisfactory performance of any equipment
are dependent upon the care given to it. To insure long life,
proper sanitation and minimum maintenance costs, the
refrigerator should be thoroughly cleaned frequently.
SHUT OFF FAN DURING CLEANING PROCESS. It can be
unplugged within the case, or shut off case at the source.
The interior bottom may be cleaned with any domestic soap
or detergent based cleaners. Sanitizing solutions will not harm
the interior bottom, however, these solutions should always
be used according to the manufacturer's directions.
It is essential to establish and regulate cleaning procedures.
This will minimize bacteria causing discoloration which
leads to degraded product appearance and signifi cantly
shortening product shelf life.
Soap and hot water are NOT enough to kill this bacteria. A
sanitizing solution MUST be included with each cleaning
process to eliminate this bacteria.
Remove all food stuffs, ice, debris, etc., and either access
the case from the rear or the front of the case. Allow the
case to come to room temperature.
