Wiring Color Code
CASE MUST BE GROUNDED
NOTE: Refer to label afxed to case to determine the actual
conguration as checked in the “TYPE INSTALLED”
boxes.
Electrical Circuit Identication
Standard lighting for all models will be full length uorescent
lamps located on the front of the parent case. The switch
controlling the lights is located on the parent case.
Electrical Service Receptacles (When Applicable)
The receptacles located on the exterior of the merchandiser
are intended for scales and lighted displays. They are not
intended nor suitable for large motors or other external
appliances.
BEFORE SERVICING
ALWAYS DISCONNECT ELECTRICAL
POWER AT THE MAIN DISCONNECT
WHEN SERVICING OR REPLACING ANY
ELECTRICAL COMPONENT.
This includes (but not limited to) Fans, Heaters
Thermostats, and Lights.
Field Wiring and Serial Plate Amperage
Field Wiring must be sized for component amperes printed
on the serial plate. Actual ampere draw may be less than
specied. Field wiring from the refrigeration control panel to
the merchandisers is required for refrigeration thermostats.
Case amperes are listed on the wiring diagram, but always
check the serial plate.
Ballast Location
Ballasts are located within the access panel that runs the
length of the rear of the case. Refer to diagram on page 6.
User Information
Stocking
Improper temperature and lighting will cause serious
product loss. Discoloration, dehydration and spoilage
can be controlled with proper use of the equipment and
handling of product. Product temperature should always
be maintained at a constant and proper temperature.
This means that from the time the product is received,
through storage, preparation and display, the temperature
of the product must be controlled to maximize life of the
product. Hussmann cases were not designed to “heat up”
or “cool down” product - but rather to maintain an item’s
proper temperature for maximum shelf life. To achieve the
protection required always:
1. Minimize processing time to avoid damaging
temperature rise to the product. Product should be
at proper temperature.
2. Keep the air in and around the case area free
of foreign gasses and fumes or food will rapidly
deteriorate.
3. Maintain the display merchandisers temperature
controls as outlined in the refrigerator section of this
manual.
4. Do not place any product into these refrigerators
until all controls have been adjusted and they
are operating at the proper temperature. Allow
merchandiser to operate a minimum of 6 hours
before stocking with any product.
5. When stocking, never allow the product to extend
beyond the recommended load limit. Air discharge
and return air ow must be unobstructed at all
times to provide proper refrigeration.
6. There are vents located at the base of the front of the
glass, just above the front rail. These vents supply a
continuous, gentle ow of air across the front glass
which inhibits condensation. Do not place any
signs or other restrictive objects on the front of
the refrigerator that will block these vents.
7. Keep the service doors closed (when applicable).
Refrigeration performance will be seriously affected
if left open for a prolonged period of time.
