Cold Wall (CW):  

Cold Wall type merchandisers utilize the merchandiser’s interior 

wall surface as the refrigeration evaporator. Frost accumulation will occur on 

all wall surfaces. The merchandiser can be defrosted by conventional methods 

using a wooden paddle or plastic scraper. Care must be exercised to prevent 

damaging piping and control parts. Do not use a sharp instrument to “chop” the 

frost from the interior surface as you may do irreparable damage. Remove the 

floor drain plug to allow water to drain.

Auto-Defrost (AD):

 Auto-Defrost (sometimes referred to as “electric defrost”) 

type merchandisers utilize a cooler evaporator with an electric defrost heating 

element to melt the frost off the evaporator coil. The defrost cycle is controlled 

by the electronic control system which energizes the electric defrost heating 

element. The electronic control is located in the condensing unit compartment. 

The control is programmed to periodically place the system in a defrost cycle 

automatically every two to four hours, depending on your control system, of 

compressor run time. The length of the defrost cycle is approximately 14 to 16 

minutes minimum and then 55°F at the coil. The electronic control used is non-

adjustable, however, defrost button may be pushed to start a manual defrost 

cycle. If your merchandiser has the electronic defrost timer, part number AT1032-1 

(not the electronic control system) you may turn the refrigeration system “OFF” 

with the toggle switch or unplug the wall plug, then turn it back to the “ON” position 

which will automatically start a manually induced defrost cycle.

Doors:

 Gaskets should be checked for tears or any other problems that would 

cause loss of seal. Replace torn/worn gaskets to maintain correct temperature 

and refrigeration efficiency.

Hinges exposed to harsh environmental conditions may require a lubricant for 

ease of operation. Spray light penetrating oil on the spring loaded hinge cartridge 

to extend the hinge life.

Finish:

 Schedule periodic cleaning of merchandiser interior and exterior. The 

cabinet can be cleaned with a mild detergent and water. 

DO NOT USE

 strong 

detergents, abrasive cleaners, or solvents, likely to leave objectionable odors 

which may be absorbed by the ice. Do not use wax or polish on the interior for the 

same reason. Wash exterior surfaces with a mild soap and warm water applied 

with a soft sponge or cloth. Wax exterior to maintain appearance and to protect 

the finish.

• Excess frost or water on the interior of the merchandiser should be removed 

or drained. Do not allow water to stand in or around the cabinet.
