7. Keep the service doors closed (when applicable).
Refrigeration performance will be seriously affected
if left open for a prolonged period of time.
8. Avoid the use of supplemental ood or spot lighting.
Display light intensity has been designed for
maximum visibility and product life at the factory.
The use of higher output uorescent lamps (H.O.
and V.H.O.), will shorten the shelf life of the product.
9. In the Deli, Meat and Fish cases, completely cover
the product each night with a clean damp cloth or
butcher paper (never use plastic, as it does not
allow for proper circulation). Make sure the cloth or
paper is in direct contact with the product.
10. Turn and rotate the meat fairly often. The blood
which gives the pink color works its way downward
with time.
11. Cold coils remove heat and moisture from the
case and deposit this as frost onto the coil. Thus,
a defrost is required. Our humidity system induces
moisture into the case and helps slow down the
dehydration process. The only other moisture within
the case is that in the product itself. A single level of
meat will dry out faster than a fully loaded case of
3-4 levels of meat.
Important Steps
1. Do not set temperature too cold, as this causes
product dehydration. Product Temperature:
33°-35°F! Set thermostat to cut in at 28°F discharge
air. Meat holding box: 32°F. Meat prep room: 55°F.
Meat bloom box: 36°F. Process the meat to enter
case at 40°F or below. Product deterioration is very
rapid above 40°F.
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.
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 entire 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
Hussmann’s directions. It is essential to establish and
regulate cleaning procedures. This will minimize bacteria
causing discoloration which leads to degraded product
appearance and signicantly 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.
1. Scrub thoroughly, cleaning all surfaces, with soap
and hot water.
2. Rinse with hot water, but do not ood.
3. Apply the sanitizing solution according to
Hussmann’s directions.
4. Rinse thoroughly.
5. Dry completely before resuming operation.
Cleaning Glass and Mirrors
Only use a soft cloth and mild glass cleaner for cleaning
any glass or mirrored components. Be sure to rinse and/or
dry completely.
Never use hot water on cold glass surfaces! It may
shatter and cause serious injury! Allow glass surfaces
to warm rst.
CLEANING PRECAUTIONS
When cleaning:
• Do not use high pressure water hoses
• Do not introduce water faster than waste outlet can drain
• NEVER USE A CLEANING OR SANITIZING SOLUTION THAT HAS AN OIL
BASE (these will dissolve the butyl sealants) or an AMMONIA BASE
(this will corrode the copper componets of the case)
TO PRESERVE THE ATTRACTIVE FINISH:
• DO USE WATER AND A MILD DETERGENT FOR THE EXTERIOR ONLY
• DO NOT USE ABRASIVES OR STEEL WOOL PADS AS THESE
WILL MAR THE FINISH
