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 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.
1. Scrub thoroughly, cleaning all surfaces, with soap
and hot water.
2. Rinse with hot water, but do not fl ood.
3. Apply the sanitizing solution according to the
manufacturer's directions.
4. Rinse thoroughly.
5. Dry completely before resuming operation.

Cleaning Glass and Mirrors

Only use a soft cloth and water 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 fi rst.

Non-glare Glass

The high optical clarity of this glass is possible due to
special coatings on the glass surface itself. To preserve this
coating and the optical clarity, keep the glass clean.
Water is the only solution recommended to be used to
clean the non-glare glass. The damage to the glass from
improper, caustic solutions is irreparable.
In addition to cleaning the glass with the recommended
product, there are precautions that should be taken when
working and cleaning the inside of the case.
• When cleaning the inside of the cases, we
recommend that the glass be fully opened and
covered to prevent to prevent solutions from
splashing onto the glass and ruining the coating on
the inside.

Plexiglass and Acrylic Care

Improper cleaning not only accelerates the cleaning cycle
but also degrades the quality of this surface. Normal daily
buffi ng motions can generated static cling attracting dust
to the surface. Incorrect cleaning agents or cleaning cloths
can cause micro scratching of the surface, causing the
plastic to haze over time.

Cleaning

Hussmann recommends using a clean damp chamois, or a
paper towel marketed as dust and abrasive free with 210
Plastic Cleaner and Polish available by calling Sumner
Labs at 1-800-542-8656. Hard, rough cloths or paper towels
will scratch the acrylic and should not be used.
