temperature to keep food at a proper serving temperature. However, the operator should always test the food 
product itself to insure proper temperatures. 

REMEMBER - THE GREATER THE THERMOSTAT NUMBER SETTING THE HIGHER THE CABINET 
TEMPERATURE AND THE LOWER THE THERMOSTAT NUMBER SETTING THE LOWER THE 
CABINET TEMPERATURE.

 

CLEANING 

 
The interior of the cart should be cleaned whenever a food spill occurs. Use a mild soap and water to clean. The plate 
racks should be removed and cleaned in a sink if necessary. 

Never use harsh chemicals or abrasive pads to clean 

the cart.

 

REPLACEMENT OF ELECTRICAL COMPONENTS 

 
It is highly recommended that only Wittco Foodservice Equipment replacement parts be used to insure compatibility of 
component parts in the operation of the banquet cabinet. 

THERMOSTAT REPLACEMENT 

 

1.     DISCONNECT THE CABINET FROM ITS POWER SOURCE.

 

2.     Remove the top cover by removing the retaining screws and lifting the cover off the cabinet to expose the 

thermostat. 

3.     Remove the black thermostat knob from the control panel by loosening the "L-end" screws that holds it to the 

thermostat stem. 

NOTE: PRIOR TO LOOSENING THE "L-end" SCREWS, TURN THE BLACK THERMOSTAT 
KNOB SO THAT THE ARROW ON THE KNOB IS IN THE "OFF" POSITION

 

4.     Notice the arrangement and connection of all electrical leads and refer to the wiring diagrams for reference. 

5.     Disconnect the wire leads connected to the thermostat. 

6.     Loosen the screws holding the temperature sensing bulb and remove it from the interior of the cabinet by pulling 

it through the access hole located in the top of the cart. The temperature sensing bulb must be replaced whenever 
the thermostat is replaced. 

7.     Remove the two screws on the front of the control panel that hold the thermostat in place and remove it along 

with the sensing bulb.
