Loading Merchandiser with Bagged Ice

After the merchandiser is operating at required temperature, load it with 

bagged ice. Bagged ice should not be stacked such that it will obstruct air flow 

in automatic defrost blower coil merchandisers.
Cold wall glass door units should have ice stacked to allow open-air access 

to thermostat sensor at upper rear interior. Approximately 3” needs to be clear 

from top of stacked ice to top of inside interior for effective refrigeration and ice 

storage.

“ON“ on the digital display means the refrigeration system has been 
“turned on”
“VH” indicates “voltage high”
“VL” indicates “voltage low”

The four buttons on the digital display will do the following:
Press and release the bottom left hand button (“OFF or ON“ will show on 
the digital display)
Manual defrost not active on cold wall units.
Arrow buttons change temperature up or down.
If the electrical power supply is interrupted the electronic control will 
always start automatically after a short delay in a new refrigeration 
cycle.

MAINTENANCE

Refrigeration: WARNING – disconnect electrical power before cleaning.

Clean refrigeration cover grill openings, condenser fins, and condenser fan 

blades at least two (2) times per year, more often if needed. A dirty condenser will 

cause the merchandiser to become less efficient, and may lead to compressor 

failure. Clean the evaporator coil and fan blades on auto-defrost merchandisers 

as required:

Defrosting:

 Frost cannot be avoided. It develops from moist air entering the 

merchandiser when the door is opened and forms on the evaporator. When the 

frost accumulation on the evaporator becomes too heavy, it acts as an insulator, 

which hinders the refrigeration efficiency.

• Clean condenser coil fins with a fine bristle brush or vacuum
• Routinely check wiring harness for loose connections or broken insulation
