BEFORE
SERVICING
Always disconnect Electrical Power at
the Main Disconnect when servicing or
replacing any electrical component.

Heaters, Thermostats, and Lights.
Ballast
FIELD WIRING & SERIAL PLATE AMPERAGE
Field Wiring must be sized for component amperes
printed on the serial plate. Actual ampere draw may be
less than specified. Field wiring from the refrigeration
control panel to the merchandisers is required for
refrigeration thermostats. Most component amperes are
listed in the “Case Specs” section, but always check the
serial plate.
Ballasts are located within the access panel that runs the
length of the rear of the case. Refer to diagram below.
Maintenance
PLEXIGLASS & 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.
C L E A N I N G
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.
CLEANING PRECAUTIONS
WHEN CLEANING:
Never Use a Cleaning or Sanitizing Solution
that has an OIL BASE (these will dissolve the
butyl sealants) or AMMONIA 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 Abrasives or Steel Wool Scouring Pads
(these will mar the finish)
CLEANING GLASS & 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
GLASS
The non-glare glass supplied in your case has a special-
ized Anti-Reflective coatings on the surface of the glass.
These coatings reduce the glare from lighting so that the
products in your display are more visible to your
customers.
While the anti reflective coatings are durable, they are
susceptible to scratching if abrasive materials or liquids
are used for cleaning. Once the glass surface is damaged,
it is IMPOSSIBLE to restore it to the original finish. The
following materials are recommended for routine
cleaning:
Specialized cleaning cloths
•Scotch Brite @ High performance Cloth - manufac-
tured by 3M and available in most grocery stores.
This cloth is washable and may be reused as long as
the cloth stays clean and free from solvents.
•Spontex® Microfibre Cleaning Cloth - distributed by
