USER INFORMATION
STOCKING
In order to maximize product life, maintain a constant and
proper product temperature from the time the product is
received through storage, preparation and display.
Products should not be placed in merchandisers until all
refrigeration controls have been adjusted and merchandis-
ers are at proper operating temperature. Care should be
taken to place the bakery trays all the way to the front of
the shelf. This avoids blocking the rear refrigerated air dis-
charge. The load limit decals are affixed to the interior of
the merchandiser. Again, air discharge and return air
flue must be unobstructed at all times to provide
proper refrigeration.
There is also a row of vents located at the base of the
front glass, just above the front rub rail. These vents allow
a gentle air flow across the front glass from the ambient
fans that prevents any condensation on the glass. Do Not
place any signs or other restrictive objects on the
front of the merchandiser that will block these

CARE AND CLEANING
Long life and satisfactory performance of any equipment is
dependent upon the care it receives. To ensure long life,
proper sanitation and minimum maintenance costs, mer-
chandisers should be thoroughly cleaned, all debris removed
and the interiors washed down, weekly.
Warning - Do Not use HOT water on COLD glass
surfaces. This can cause the glass to shatter and
could result in personal injury. Allow glass fronts,
ends and service doors to warm before applying
hot water.
Exterior Surfaces - The exterior surfaces must be cleaned
with a mild detergent and warm water to protect and
maintain their attractive finish. Never use abrasive
cleansers or scouring pads.
Front Glass - DO NOT use the front glass as a support
during cleaning. Removal of the glass is NOT recommended.
Interior Surfaces - The lower display decks are remov-
able by sliding open rear drawer and lifting them up and
out. The interior surfaces may be cleaned with most do-
mestic detergents, ammonia based cleaners and sanitizing
solutions with no harm to the surface.
CAUTION: SHUT FAN OFF DURING CLEANING
IMPORTANT STEPS
1. For temperature settings, please see the Case
Specifications section in this book.
2. Temperature control should be by means of a T-Stat
and Suction Stop Solenoid at each case. Do not use
EPR valves, Liquid Line Solenoids or electronic
control devices of any kind, as these allow
temperature swings causing dehydration and
excessive energy consumption.
3. Product should be worked and rotated on a regular
basis, not to exceed a 4-hour period.
4. At night, turn off case lights and cover the product
with a damp (not wet) cloth similar to cheese cloth
(etc.). This should be washed out in the morning and
kept in a walk-in box during the day—so that it is cool
and moist when covering the product.
5. Discharge air temperature should be approximately
26°F, with between 150-200 FPM air velocity. Do not
display product directly within the air discharge.
6. Clean Humidity system a minimum of every 90 days
for proper system operation.
