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.

.   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 flue  must be unobstructed at all 

times to provide proper refrigeration.

  

6.  Keep the service doors closed (when applicable). 

Refrigeration performance will be seriously affected 

if left open for a prolonged period of time.

7.  Avoid the use of supplemental flood or spot lighting. 

Display light intensity has been designed for maximum 

visibility and product life at the factory. The use of 

higher output fluorescent lamps (H.O. and V.H.O.), will 

shorten the shelf life of the product.

important Steps

1.  Do not set temperature too cold, as this causes 

product dehydration.  

Recommended Omni-Stat Temperature Control 

Settings: 

-RCD 6° 

-FMSS-LT -15° 

See Case Specifications for Details.

.   Temperature control is adjusted by the Omni-Stat 

Temperature Controller.

case cleaning

Long life and satisfactory performance of any equipment 

are dependent upon the care given to it. To insure long 

life, proper sanitation and minimum maintenance costs, 

the refrigerator should be thoroughly cleaned frequently. 

SHUT OFF FAN DURING CLEANING PROCESS. It can be 

unplugged within the case, or shut off case at the source. 

The interior bottom may be cleaned with any domestic soap 

or detergent based cleaners. Sanitizing solutions will not 

harm the interior bottom, however, these solutions should 

always be used according to Hussmann’s directions. It is 

essential to establish and regulate cleaning procedures. 

This  will  minimize  bacteria  causing  discoloration  which 

leads to degraded product appearance and significantly 

shortening product shelf life.

CLEANING PRECAUTIONS 

When cleaning: 

Do not use high pressure water hoses 

Do not introduce water faster then waste outlet can drain 

NEVER INTRODUCE WATER ON SELF CONTAINED UNIT 

WITH AN EVPORATOR PAN 

NEVER USE A CLEANING OR SANITIZING SOLUTION 

THAT HAS AN OIL BASE (these will dissolve the butyl 

sealants) or an AMMONA 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 A CHLORANITED CLAENER ON ANY 

SURFACE 

DO NOT USE ABRASIVES OR STEEL WOOL SCOURING 

PADS (these will mar the finish) 

CAUTION

Soap  and  hot  water  are  not  enough  to  kill  bacteria. A 

sanitizing  solution  must  be  included  with  each  cleaning 

process to eliminate bacteria.

1.   Clear debris and solid food product that may be in 

areas that need cleaning.

.   Using a spray bottle, apply cleaning solution liberally 

to surfaces. Thoroughly scrub all surfaces using a 

non-abrasive cloth.

3.   Using another spray bottle containing only water, 

rinse surfaces that require rinsing. 

do not use 

running water to rinse. See warning above.

4.   Dry completely using a clean, non-abrasive cloth.
