Appendix D. - Recommendations to
User
1.0 Hussmann Corporation provides instructions
and recommendations for proper periodic
cleaning. The user will be responsible for
such cleaning, including the cleaning of low
temperature equipment within the compartment
and the cooling coil area(s). Cleaning practices,
particularly with respect to proper refrigerator
unloading and warm-up, must be in accordance
with applicable recommendations.
1.1 Cleaning of non frozen food equipment
should include a weekly cleaning of the food
compartment as a minimum to prevent bacteria
growth from accumulating. Actual use and
products may dictate more frequent cleaning.
Circumstances of use and equipment design
must also dictate the frequency of cleaning the
display areas. Weekly washing down of the
storage compartment is also recommended,
especially for equipment subject to drippage
of milk or other liquids, or the collection of
vegetable, meat, crumbs, etc. or other debris
or litter. Daily cleaning of the external areas
surrounding the storage or display compartments
with detergent and water will keep the equipment
presentable and prevent grime buildup.
1.2 Load levels as defi ned by the manufacturer must
be observed.
1.3 The best preservation is achieved by following
these rules:
a) Buy quality products.
b) Receive perishables from transit equipment
at the ideal temperature for the particular
product.
c) Expedite perishables to the store's storage

equipment to avoid unnecessary warm-up
and prolonged temperature recovery. Food
store refrigerators are not food chillers nor
can they reclaim quality lost through previous
mishandling.
d) Care must be taken when cross
merchandising products to ensure that
potentially hazardous vegetable products are
not placed in non refrigerated areas.
e) Display and storage equipment doors should
be kept closed during periods of inactivity.
f) Minimize the transfer time of perishables
from storage to display.
g) Keep meat under refrigeration in meat cutting
and processing area except for the few
moments it is being handled in processing.
When a cut or tray of meat is not to be
worked on immediately, the procedure should
call for returning it to refrigeration.
h) Keep tools clean and sanitized. Since
mechanical equipment is used for fresh
meat processing, all such equipment should
be cleaned at least daily and each time
a different kind of meat product comes in
contact with the tool or equipment.
i) Make sure that all refrigeration equipment is
installed and adjusted in strict accordance
with the manufacturer's recommendations.
j) See that all storage and refrigeration
equipment is kept in proper working order by
routine maintenance.
