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 significantly 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 flood.
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 first.

CAUTION
CLEANING PRECAUTIONS
When cleaning:
Do not use high pressure water hoses
Do not introduce water faster then waste outlet can drain
NEVER INTRODUCE WATER ON SELF CONTAINED UNIT
WITH AN EVPORATOR PAN
NEVER USE A CLEANING OR SANITIZING SOLUTION
THAT HAS AN OIL BASE (these will dissolve the butyl
sealants) or an AMMONA BASE (this will corrode the
copper components of the case)
TO PRESERVE THE ATTRACTIVE FINISH:
DO USE WATER AND A MILD DETERGENT FOR THE
EXTERIOR ONLY
DO NOT USE A CHLORINATED CLEANER ON ANY
SURFACE
DO NOT USE ABRASIVES OR STEEL WOOL SCOURING
PADS (these will mar the finish)
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 for use in cleaning
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 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
buffing 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 marked 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.
Antistatic Coatings
The 210
has proven to be very effective in not only
®
cleaning and polishing the Plexiglass surface, but also
providing antistatic and anti-fog capabilities. This product
also seals pores and provides a protective coating.
