INTRODUCTION

Wittco Foodservice Equipment's Touchmaster Cook and Hold Oven System is a basic unit of food preparation
equipment. It has found wide acceptance in both institutional and commercial food service operations.

This manual has been produced to provide persons responsible for the operation and maintenance of the oven with a
simple but comprehensive understanding of its proper use. We recommend that this manual be read and understood
prior to placing the oven into operation.

As with any piece of food service equipment, this oven system 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: BEFORE USING THE OVEN IT SHOULD BE THOROUGHLY CLEANED IN ACCORDANCE
WITH THE INSTRUCTIONS CONTAINED IN THIS MANUAL.

It is recommended that prior to placing the oven system into operation that it be operated on the cook cycle for
approximately two (2) hours at 350° F.

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.

It is our sincere desire that you obtain the maximum benefit from your Cook and Hold Oven System. If at any time
questions arise or additional information is required, contact Wittco at 800 367-8413.

DESCRIPTION
Operators have found that cooking foods utilizing low temperature methods reduces the amount of product shrinkage

and increases the amount of product yield. This is because less moisture is cooked out of the food when it is prepared
at 225° F. than when it is prepared at 350° F. Because of this fact, the operator will serve a product that has greater
customer satisfaction because of the increased flavor and moisture this meat possesses.

UNCRATING

Each Wittco Foodservice Equipment oven 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 lift the cabinet off the carton bottom and pallet and place it on the floor. Note: The casters for the
Touchmaster III are shipped in a separate carton. Remove it and install the casters on the oven.

4. Remove the box containing the cooking racks that are supplied with the oven.

5. Remove any packing materials which may have been used to hold the tray slides in place.

6. Heat the oven at 350° F for approximately 2 hours before using.

CABINET LOCATION

PLACING THE OVEN IN THE PROPER LOCATION IS IMPORTANT FOR EFFICIENT OPERATION.
CHOOSE A LOCATION FOR THE OVEN IN AN AREA WHICH WILL PROVIDE EASY LOADING
AND UNLOADING WITHOUT INTERFERING WITH THE FINAL ASSEMBLY OF FOOD ORDERS.
PROVIDE AT LEAST SIX INCHES OF SPACE ON EACH SIDE OF THE OVEN FOR PROPER Am
CIRCULATION AROUND THE OVEN.

OPERATING CONTROLS

A complete explanation of the operating controls will be found in the Cook Guide which is supplied with the oven.

All operating controls are located on the front control panel. This panel contains the on/off button and the touch pad
operating controls.

NOTE: IT IS RECOMMENDED THAT THE OVEN CONNECTION TO THE POWER SOURCE BE
DONE BY A LICENSED ELECTRICIAN.

NOTE: UPON CONNECTING THE CONTROL MODULE TOP TO THE POWER SOURCE, THE
COOLING FANS MAY NOT OPERATE. THESE FANS WILL ONLY OPERATE WHEN THE
THERMOSTAT TO WHICH THEY ARE CONNECTED REQUIRES IT.

ELECTRICAL REQUIREMENTS

Wittco Cook and Hold Ovens can be factory wired for 120, 208,220, or 240 volts AC, single or three
phase, 60 or 50 cycle service.

VERIFY THAT THE VOLTAGE AND PHASE OF THE POWER SOURCE IS IDENTICAL TO
THE OVEN SYSTEM DATA PLATE BEFORE CONNECTING.

The oven must be adequately and safely grounded before operation. A separate disconnect switch or
circuit breaker is recommended at a convenient location between the oven and power source.

TESTING THE OVEN

Each oven is completely checked and tested prior to shipment. However, it is a good practice to
completely check the unit again after unpacking and installation.

1. Connect oven to power source.

2. Turn the oven on by depressing the power button.

3. Set the roasting oven temperature by depressing the up/down arrow touch pad until the LED
display reads 350° F and then depress the enter touch pad.

4. Set the hold temperature by pushing the up/down arrow touch pads until the LED display reads 140° F and then
depress the enter touch pad.

5. Set the roasting time by pushing the time touch pad and the up/down arrows until the LED indicator shows
1:00 (one hour)

6. Depress the start cook touch pad.

7. The oven should immediately start heating. The red "heat" indicator light will

illuminate. At this time the LED will read 01:00 in the top section and the bottom section will read 350. The
Cook indicator light will also be illuminated. The oven timer will begin to count down to 0:00 and when it
reaches that point the oven will switch from the roasting to the holding cycle.

If all of the functions perform satisfactorily, the oven is ready for operation.

CLEANING

The interior of the oven should be cleaned whenever a food spill occurs. Use a mild soap and water to clean. Never use
harsh chemicals or abrasive pads to clean the cabinet.
The simple cleaning process follows.

1 DISCONNECT THE OVEN FROM THE POWER SOURCE.

2. Remove the control module top and place it away from the oven cabinet.

CAUTION - THE OVEN INTERIOR COMPARTMENT SHOULD NEVER BE HOSED DOWN
WHEN THE CONTROL MODULE TOP IS ON THE OVEN BODY.

3. Lift and tip the side tray racks toward the center of the cabinet. Remove them from the cabinet. These racks
should be taken to a sink or dish washer for a thorough cleaning.

4. Remove the interior rear mounted air distribution tunnel and take it to a sink or dish washer for cleaning.

5. Clean the interior oven cavity with soap and water.

6. Reassemble the oven.

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 cook and hold oven
