Operation
Merchandise should not be placed in the fixture until all controls have been adjusted and the case is at the proper
temperature. AT NO TIME SHOULD THE CASE BE STOCKED BEYOND THE LOAD LIMIT LINE OR OVER THE
FRONT EDGE OF THE ADJUSTABLE SHELVES.
CAUTION: Air discharge and return flues must remain open and free of debris or obstruction at all times to provide
proper refrigeration and air curtain performance.
CAUTION: Do not allow any product, signs, debris, etc., to block these grilles.
CAUTION: Do not use any non-approved shelving, display racks, or any accessory that could hamper air curtain
performance.
WARNING! Do not walk on top of the cases! This could result in damage to the case and serious personal injury
could occur. These cases are not designed to support excessive external weight. Do not use top of cases for storage.
1. Off-Cycle Defrost is standard on these models. The fans run continuously and defrost termination is by
termination sensor/Klixon.
2.
Electric Defrost Models are standard for low temperature cases. Electric heaters are utilized to melt the frost
and ice on the coil. The heaters are located in the air stream underneath the coil. The defrost cycle is time
initiated and temperature terminated. Case fans shut off during defrost. During refrigeration the fans start after
the evaporator coil temperature reaches 10ºF and run continuously thereafter. As a safety precaution, a safety
cutoff Klixon is wired in series with the defrost heater to turn the heater off at temperatures above 65ºF.
3. Single Condensing Case Systems – A thermostat should be used to control case temperatures. The ther-
mostat bulb should be mounted in the discharge air (see case data if your case is a single condensing case
system).
Cleaning
As a general rule, always use mild soap and water to wipe the case down, including the sliding doors at the back of
the case. Special precautions must be taken when cleaning some components of the case.
Exterior surfaces should be cleaned with warm water and mild soap to protect and maintain the finish. Do not use
cleaners containing abrasive materials or ammonia, which will scratch or dull the finish. The waste outlet should be
flushed with water following each cleaning.
Interior surfaces may be cleaned with most mild soap formulas, ammonia based cleaners, and sanitizing solutions
with no harm to the surface.
WARNING! Always shut power off during the cleaning process. Cleaning the case with electrical power applied is a
shock hazard that may cause serious injury or death.
WARNING! DO NOT USE HOT WATER ON COLD GLASS SURFACES. This could cause the glass to shatter and
could result in personal injury. Glass fronts and ends should be warm before applying hot water.
