INTRODUCTION

The 1826 DBL and 1826 DBL IS series of commercial and institutional cabinets from Wittco Foodservice Equipment

provide an efficient and sanitary method of holding and transporting prepared food products. Because these cabinets

provide individual controls for each of the two compartments, the operator is able to hold two different products at two

different temperatures in separate sections of the same unit. They have found wide acceptance in all types of food

service operations. Schools, hospitals, restaurants, and correctional facilities 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, this holding and transport cabinet 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 holding and transport cabinet should be cleaned in accordance with the instructions contained in

this manual.

It is recommended that prior to placing the holding and transport cabinet 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 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 heated holding and transport cabinet. If

at any time questions arise or additional information is required, contact Wittco at 800 367-8413.

DESCRIPTION

The Wittco 1826 DBL series cabinets provide an efficient means of holding and transporting bulk prepared foods at

proper serving temperatures. The 1826 DBL commercial series cabinets will accommodate 7 each 18 X 26 sheet pans,

7 each 12 X 20 X 2 1/2 steam table pans, or a combination of both by utilizing the adjustable universal tray slides. The

1826 institutional series will accommodate 7 each 18 X 26 sheet pans, 14 each 12 X 20 X 2 1/2 steam table pans, or a

combination of both. It will also accommodate 1/1 or 2/1 gastronome pans.

UNCRATING

Each Wittco Foodservice Equipment cabinet 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. Carefully move the cabinet off the carton bottom and pallet.

4. Open the cabinet doors and remove the boxes containing the adjustable tray slides and upright tray slide side

supports.

5. Remove the cardboard element cover protector from the bottom of the cabinet.

6. Open the boxes and install the tray slide supports in each compartment. To install the supports, hook the openings

in flat flange of the support over two vertical carriage bolts on the interior of the cabinet. Make sure that all

flanges on the four supports are facing the door opening. Remove the adjustable tray slides from the box and

install them in the cabinet. The hook on the end of the slide must be up in order for slides to be properly installed.

7. Pre-heat the cabinet for 30-45 minutes before using.

ELECTRICAL REQUIREMENTS

The 1826 series of holding and transport cabinets 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 1826 DBL series cabinets contains a dual indicator operating light with both amber and red

lamps, a dial thermometer, and a full range thermostat.

After the cabinet is connected to an appropriate power source, the operator will notice that the red indicator lights are

illuminated. These lights will continue to be on as long as the cabinet is connected to the power source.

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 lights will be illuminated. These lights 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 lights will turn on and off.

As the elements are heating, the thermometers will begin to move and indicate the interior temperature of the

compartments. 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 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 CABINET

TEMPERATURE AND THE LOWER THE THERMOSTAT NUMBER SETTING THE LOWER THE

CABINET TEMPERATURE.

CLEANING

The interior of the compartments should be cleaned whenever a food spill occurs. Use a mild soap and water to clean.

The tray slides should be removed and cleaned in a sink if necessary. Never use harsh chemicals or abrasive pads to

clean the cabinet.

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 holding and transport

cabinet.

The controls of the lower compartment are accessed by opening the door and removing the door gasket from the top of

that compartment. Two screws are then visible and when they are removed, the control panel will tip forward allowing

access to the compartment controls.
