Wiring and Serial Plate Amperage

Field Wiring must be sized for component amperes stamped 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.

ASHRAE Color Code

NOTE: All other manufacturers have no standard sensor codes.

Bumper Installation Tips

1.Start to attach the bumper at one end of the lineup, preferably on a straight case.

2.Push the end of the bumper into the bumper channel firmly. This may be difficult if bumper is cold.

3.Bend the bumper backwards to open and guide it forward onto the bumper channel.

4.An inside bumper miter must be cut on wedges.

5.Loose ends on miters must be anchored with screws on the bottom edge.

6.The top and bottom edges of the bumper must be firmly seated into the retainer by applying with a rubber mallet (not by hand).

7.The bumper should be struck by the mallet at a slight angle that forces the bumper back into itself to prevent stretching. The installation can be made easier by applying a paraffin block to the retainer grooves.

Installing Splashguard

After merchandisers have been leveled and joined, and all drip piping, electrical and refrigeration work has been completed, install the splashguards. Splashguards may

be sealed to the floor using a vinyl cove base trim. The size of trim needed will depend on how much the floor is

out of level.

NOTE: The splashguard must be removable to allow access to components behind it.

1.Remove all dirt, wax, debris, etc. from the area of the splashguard to ensure a secure adhesion.

2.Apply a good contact cement to the trim, allowing a proper dry time.

3.Install trim to the splashguard so that it is flush with the floor.

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 six (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.
