It is recommended that prior to placing the drawer warmer into operation that it be pre-heated
at the highest temperature setting for 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 commenced.

warmer system. If at any time questions arise or additional information is required, contact
Wittco at 800 367-8413.
DESCRIPTION
The Wittco 200 series of Slim-Line drawer warmers provide an efficient means of holding a
variety of prepared hot food products at proper temperatures until serving. The 200 Slim-Line
series is provided with a large 12 X 20 X 4 steam table pan insert.
UNCRAT1NG
Each Wittco drawer warmer system is packed in a cardboard carton. When the unit is received
by the operator, the carton should immediately be inspected for any sign of visible exterior
damage to the carton. If the carton is punctured or dented, it many be an indication that the unit
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. -1-

UNPACKING THE UNIT
Remove the cardboard carton and the plastic bag covering the unit.
Carefully lift the unit off the carton bottom and pallet and place it on the floor or table.
Remove the legs for the unit located in the drawer of the unit.
Secure the legs to the bottom of the drawer warmer by screwing the legs into the holes
provided.
Remove any and all packaging materials in the drawers.
Thoroughly clean the unit as described in the instructions.
ELECTRICAL REQUIREMENTS
The 200 Slim-Line drawer warmer series are factory wired for either 110/120 volt or 208/240
volt, singles phase operation. All 110/120 volt units are equipped with a 8 foot cord and NEMA
5-15 plug as standard equipment. All 208/240 volt units are equipped with a 8 foot cord and
NEMA 6-15 plug.
CAUTION: Verify that the power source matches the data plate on the lower rear corner
of the unit and the plug configuration before the connection is made.
OPERATION
The control panel of the 200 series contains an operating indicator light and full range
thermostat.
Once the unit has been connected to the appropriate power source the unit is ready for operation.
the operating thermostat also acts as the on/off switch to the drawer warmer system. Turning
the thermostat counter clock-wise until it stops will turn the system off.
Rotate the thermostat dial so that it points to the number 5. This will cause the heating elements
to start heating. When this occurs the red operating indicator light will illuminate, this light
will stay on as long as the heating element are engaged. Once the predetermined temperature
is achieved, the heating element will begin to cycle. During this period the red operating
indicator light will turn on and off as the heating elements cycle.
As the heating elements are heating, the thermometer will begin to move and indicate the interior
temperature of the cabinet. At the number 5setting the thermometer should indicate an average
temperature of approximately 150 degrees F.
NOTE: The temperature in any heated unit will fluctuate as the heating element cycle on
and off. The thermostat setting will provide an average temperature in the unit. However,
the operator should always monitor the food product to insure that it remains at proper
temperatures.
