INTRODUCTION
The banquet cart series cabinets from Wittco Foodservice Equipment provide an efficient and sanitary method of
holding and transporting pre-plated food products in a banquet facility. The carts are designed to accommodate
covered or uncovered plates. The covered plates can be used with or without plate carriers and the uncovered plates
require the use of plate carriers. Each cart is designed to hold a predetermined number of 10 1/2 inch plates. They have
found wide acceptance in all types of food service operations. Hotels, restaurants, and casinos are all users of these
dependable and useful cabinets.
This manual has been produced to provide persons responsible for the operation and maintenance of the equipment
with a simple but comprehensive understanding of its proper use. We recommend that this manual be read and
understood prior to placing the cabinet in operation.
As with any piece of food service equipment, these banquet service carts will require a minimum amount of care and
maintenance. Suggestions for this procedure are contained in this manual and should become a regular part of the
operation of the unit.
NOTE: The banquet cart should be cleaned in accordance with the instructions contained in this manual.
It is recommended that prior to placing the banquet cart into operation that it be preheated at the highest temperature
setting for a period of 30-45 minutes.
Should repair or adjustment of the unit become necessary, we suggest that procedures described in this manual be
followed. The operator may also contact the authorized Wittco dealer who sold the product or an authorized Wittco
service agency. If the needed repair occurs during the warranty period, prior authorization is required from Wittco by
the service company before the work is done.
It is our sincere desire that you obtain the maximum benefit from your Wittco banquet cabinet. If at any time questions
arise or additional information is required, contact Wittco at 800 367-8413.
DESCRIPTION
The Wittco banquet carts provide an efficient means of holding and transporting pre-plated meals at proper serving
temperatures. These units have been designed around a 10 1/2" plate. If larger or smaller plates are used the capacities
will either increase or decrease. They will also accommodate optional covered or uncovered plate carriers.
UNCRATING
Each Wittco Foodservice Equipment banquet cart is packed in a cardboard carton which, in turn, is banded to a
wooden pallet. When the cabinet is received by the operator, the carton should immediately be inspected for any sign
of visible exterior damage. If carton is

punctured or dented, it may be an indication that the cabinet has sustained concealed freight damage.
It is very important that any evidence of damage be noted on the Bill of Lading at the time of receipt.
UNPACKING THE CABINET
1. Remove the banding material holding the carton to the pallet.
2. Remove the cardboard carton and the plastic bag covering the cabinet.
3. Remove the banding material holding the banquet cart to the skid.
4. Carefully move the banquet cart from the skid.
5. Open the doors and remove all packing materials and the retaining straps which have been used to hold the wire
plate racks in place.
6. Lift the wire plate racks into position on the side brackets.
7. Pre-heat the cabinet for 30-45 minutes before using.
ELECTRICAL REQUIREMENTS
The banquet service cart series are factory wired for either 110/120 volt or 208/240 volt, single phase operation. All
110/120 volt units are equipped with an 8 foot cord and NEMA 5-15 plug as standard equipment. All 208/240 volt
units are equipped with an 8 foot cord and NEMA 6-15 plug.
CAUTION: Verify that the power source matches the data plate on the lower rear of the cabinet and the plug
configuration before the connection is made.
OPERATION
The control panel of the banquet service carts contains a dual indicator operating light with both amber and red lamps,
a dial thermometer, and a full range thermostat.
After the cart is connected to an appropriate power source, the operator will notice that the red indicator light is
illuminated. This light will continue to be on as long as the cabinet is connected to the power source.
Rotate the thermostat knob so that it points to the number 5. This will cause the heating elements to start heating.
When this occurs the amber indicator light will be illuminated. This light will stay on as long as the heating elements
are engaged. Once the predetermined temperature is achieved, the heating elements will begin to cycle. During this
period the amber light will turn on and off.
As the elements are heating, the thermometer will begin to move and indicate the interior temperature of the cabinet.
At the number 5 setting the thermometer should indicate an average temperature of approximately 150 degrees0F.
NOTE: The temperature in any heated cabinet will fluctuate as the heating elements cycle on and off. The
thermostat setting will supply an average temperature air

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.
