INTRODUCTION

The Wittco 600 series can be either mobile (with casters) or counter top (with legs) for transporting, holding and displaying prepared food products for either self-service grab and go programs or operator serviced programs.

As with any piece of food service equipment, this unit will require a minimum 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 unit should be thoroughly cleaned in accordance with the instructions contained in this manual.

It is recommended that prior to placing the unit into operation that it be pre-heated 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 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 display/merchandising system. If at any time questions arise or additional information is required, contact Wittco at 800 367-8413.

DESCRIPTION

The Wittco 600 series provides an efficient means of transporting, holding, displaying and merchandising a variety of prepared foods at proper serving temperatures. These units are provided with adjustable and removable wire racks.

UNCRATING

Each Wittco unit 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. 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 UNIT

1. Remove the cardboard carton and the plastic protective bag covering the unit.

2. Install the legs packaged with the unit by screwing the legs into the holes provided on the bottom of the unit.

NOTE: Casters are factory installed when ordered.

3. Open the door to the unit and remove all packaging materials.

4. Install the removable adjustable wire shelves.

5. Pre-heat the unit at its highest temperature for a period of 30-45 minutes.

ELECTRICAL REQUIREMENTS

The Wittco 600 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 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 located on the unit and the plug

configuration before the connection is made.

OPERATION

The control panel of the 600 series contain dual operating indicator lights, full range thermostat, and dial thermometer.

After the unit has been 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 unit 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 element is engaged. Once the predetermined temperature is achieved, the heating element will begin to cycle. During the cycling period the amber light will turn on and off.

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

NOTE: The temperature in any hearted cabinet will fluctuate as the heating elements cycle on and off. The thermostat setting will provide an average air temperature in the cabinet. However, the operator should always

monitor the food product to insure that it remains at proper temperatures.

REMEMBER - THE GREATER THE THERMOSTAT NUMBER SETTING THE HIGHER THE

SURFACE TEMPERATURE AND THE LOWER THE THERMOSTAT NUMBER SETTING THE

LOWER THE TEMPERATURE.

CLEANING

Witteo 600 series are constructed from heavy duty stainless steel. It is highly recommended that when cleaning only a mild soap and water solution be used to clean. Never use harsh chemicals or abrasive pads

to clean the cabinet.
