CAUTION: DO NOT THROW ITEMS INTO THE STORAGE AREA. FAILURE TO HEED THESE
RECOMMENDATIONS COULD RESULT IN DAMAGE TO THE INTERIOR OF THE
CABINET.
REFRIGERATED CABINETS
Temperature range for the internal cabinets is 34°F to 38°F for all food prep units,
worktop refrigerators.
The rail's temperature range for all prep units is 33°F to 41°F.
Food Prep units should operate with pans in place. Operating without pans and/
or pan covers in place will lower the efficiency and may damage the unit due to
continuous over-use.
Continuous opening and closing of the door will prevent the unit's ability to maintain
optimum refrigeration temperature.
Top section is not intended for overnight storage. Product should be removed from
pans. Pans can remain in cabinet if empty.
DEFROSTING
Every 6 hours, the unit will turn off so the evaporator coil can defrost. The controller
now displays the defrost symbol. When the coil temperature reaches the terminal
temperature or after 20 minutes of defrost, the unit will turn on.
