Service and Installation Manual                                         

 

OPERATION                                                                                                                                               

 

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 28° F to 50° F for all food prep, undercounter and worktop 
refrigerator units; and -11° F to -1° F for undercounter and worktop freezers.     
Food Prep units should operate with pans in place. Operating without pans and/or pan covers in place 
will decrease the efficiency and may damage the unit due to continuous running. 

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 while empty. 

Defrosting:   

Every 6 hours, the unit will turn off to let the ice on the evaporator coil clear up. The control will display the 
defrost symbol. When the coil temperature reaches the terminal temperature or after 20 minutes 
(whichever comes first), the unit will turn on again.

 

On/Off Switch: 

An on/off switch is located on the front of the bottom panel and on the condenser compartment door for the 
Pizza prep tables. When the unit is on, the switch will glow green.
