DESCRIPTION
The Wittco 1220-105 series provides an efficient means of transporting, holding, displaying and serving a variety of

prepared foods at proper serving temperatures. These units are provided with individual thermostatically controlled
heated compartments, an ambient holding compartment, and top mounted heated serving wells. The holding
compartments accommodate the standard 12 X 20 steam table pans of depths up to six inches.

UNCRATING
Each Wittco unit is packed in either a cardboard carton and skidded or crate and skid depending upon the model. When

the unit is received by the operator, the carton should immediately be inspected for any sign of visible exterior damage.
If carton or crate 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 UNIT

1. Remove the cardboard carton from the skid or the wood crating from the skid depending upon the model.

2. Remove all exterior packaging and protective materials from the unit.

3. Carefully remove the unit from the skid.

4. Open all doors to the holding compartments and remove all interior packaging materials.

5. Pre-heat the unit by turning all the thermostats to their highest temperature for a period of 30-45 minutes.

ELECTRICAL REQUIREMENTS

The Wittco 1220-105 series are factory wired for either 110/120 volt or 208/240 volt, single phase operation
depending upon the model. All 110/120 volt units are equipped with an 8 foot cord and NEMA 5-15 plug as
standard equipment. All 208/240 units are equipped with an 8 foot cord and NEMA plug compatible to the total
wattage load depending upon the model.

CAUTION: Verify that the power source matches the data plate on the located on the unit and the plug
configuration before the connection is made.

OPERATION

The control panels of the 1220-105 series contain dual operating indicator lights for the holding compartments,
single operating indicator light for each top mounted heated well, full range thermostat for each holding
compartment and top mounted heated well, and dial thermometer for each holding compartment.

After the unit has been connected to an appropriate power source the operator will notice that the red indicator
light(s) are illuminated. This light(s) will continue to be on as long as the unit is connected to the power source.

HEATED HOLDING COMPARTMENTS - Rotate the thermostat knobs so that they point to the number 5. This
will cause the heating elements to start heating. When this occurs the amber indicator light(s) will be illuminated.
This light(s) will stay on as long as the heating element(s) is engaged. Once the predetermined temperature is
achieved, the heating element(s) will begin to cycle. During the cycling period the amber light(s) will turn on and
off.

As the element(s) is heating, thermometer will begin to move and indicate the interior temperature of the unit. At
the number 5 setting the thermometer(s) should indicate an average temperature of approximately 150 degrees F.

HEATED TOP MOUNTED SERVING WELLS - Rotate the thermostat knob so that it point to the number 5. This
will cause the well heating element to start heating. When this occurs the red single indicator light will illuminate.
This light will stay on as long as the heating element is engaged. Once the predetermined temperature is achieved,
the heating element will begin to cycle. During the cycling period the red light will turn on and off.
