Electrical
Wiring Color Code
CASE MUST BE GROUNDED
NOTE: Refer to label affixed to case to determine the actual configuration as checked in the “TYPE INSTALLED” boxes.
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 specified. 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.
Electrical Circuit Identification
Standard lighting for all models will be full length fluorescent 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.
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 flow 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 flow 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.
