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
i
PDF compression, OCR, web optimization using a watermarked evaluation copy of CVISION PDFCompressor

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
Remove the banding material holding the carton to the pallet.
Remove the cardboard carton and the plastic bag covering the cabinet.
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.
Remove the box containing the cooking racks that are supplied with the oven.
Remove any packing materials which may have been used to hold the tray slides in
place.
Heat the oven at 35Ø0 Ffor 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 AIR CIRCULATION AROUND THE OVEN.
OPERATING CONTROLS
A complete explanation of the operating controls will be found in the Cook Guidewhich 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 CONNECTD4G.
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.
Connect oven to power source.
Turn the oven on by depressing the power button.
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.

Set the hold temperature by pushing the up/down arrow touch pads until the LED
display reads 1400 F and then depress the enter touch pad.
Set the roasting time by pushing the time touch pad and the up/down arrows until
the LED indicator shows 1:00 (one hour)
Depress the start cook touch pad.
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.

TROUBLE SHOOTING PROCEDURE
WARNING: EXTREME CAUTION MUST BE EXERCISED WHEN WORKING
AROUND ELECTRICAL EQUIPMENT TO PREVENT THE POSSIBILITY OF
ELECTRICAL SHOCK RESULTING IN INJURY OR DEATH. THESE TEST
PROCEDURES SHOULD ONLY BE DONE BY A LICENSED ELECTRICIAN
OR AN AUTHORIZED SERVICE AGENCY.
Always work in a safe manner. Be sure the power supply is turned off before touching any
wires or terminals to prevent the possibility of electrical shock or damage as a result of
electrical short by the meter probes.
No wires should be disconnected from the terminals without first disconnecting the power
source to the oven.
This procedure supplies a list of symptoms that may be observed and a reference section
that may be referred to locate and correct the problem.
TEST EQUIPMENT REQUIRED
The preferred piece of equipment required is a DVM (Digital Voltmeter) and a clamp-on
ammeter. If one of these is not available, on ohmmeter is necessary to determine if a short
circuit or a ground exists. The meter should be capable of reading O to loo k ohms full
scale.
NORMAL OPERATION
It is preferred that the technician has had the opportunity to observe the normal operation
of the oven so that when there is a malfunction, it may be easily recognized with a
minimum of testing.
In normal operation, as soon as power is applied to the oven and the power switch is
turned on, the HEAT and the COOK CYCLE indicator lights should be illuminated. In
addition, the air circulating fans inside the oven should start.
TROUBLE SHOOTING
I. NO HEAT IN THE HOLD CYCLE
Check that the oven is connected to the power source and the circuit breaker or
fuse is not tripped.
Check that the oven power switch is on.
If the power switch is in the on position and the heat indicator light is not
illuminated, remove the fuses and verify continuity with the ohmmeter. If the fuses
'o
PDF compression, OCR, web optimization using a watermarked evaluation copy of CVISION PDFCompressor

are defective, there is probably a shorted component or wire. Refer to Section A
for additional testing.
Replace fuses with the same type that were supplied with the oven. Use only
#SLC-3 current limiting fuse, Type G, 250 volt.
II. ERROR DETECTION
When a "000" is displayed in the lower LED display during a Cook or Hold cycle,
it indicates that the temperature sensing probe is open or shorted.
When a "000" is displayed in the lower LED display during a probe cook function,
it indicates that the product sensing probe is open or shorted.
SECTION A. TESTING FOR GROUNDS AND/OR SHORTED COMPONENTS
DISCONNECT THE OVEN FROM THE POWER SOURCE BEFORE
PERFORMING ANY TESTING WITH AN OHMMETER
TESTING FOR GROUNDS
Power switch in the off position.
Connect on lead of the ohmmeter to the metal oven top.
Touch the other lead to the following and observe that there should be an open
circuit in each case:
Ti on element contactor
T2 of element contactor
Wire 7 on vent fan switch
Wire 29 on power switch
Wire 50 on power switch
Wire 10 on power switch
Wire 29 on power switch
Any reading at all, indicates a component partially or completely shorted to
ground.
TESTING FOR SHORTED COMPONENTS
Test the following to determine which component is shorted. If any component has
significantly lower reading than is listed, it is suspect and should be replaced.
TESTING HEATING ELEMENTS
Test between Ti and T2 on the contactor with the ohmmeter and compare the
value to the table below:
11
PDF compression, OCR, web optimization using a watermarked evaluation copy of CVISION PDFCompressor

The basic element has a resistance of 23 ohms regardless of the voltage rating on
the oven. Because the number of elements in the oven effects the reading, compare
the number of elements in the oven to the following chart to determine if any
elements are open or shorted.
I element
23 ohms 2 elements
11.5 ohms
Reconnect the wires to the terminal strip.
WIRING INSPECTION
Check for frayed or touching wires on any terminal strip, especially on the set
point relay. Clean and dress up the wires as needed.
TESTING THE MOV VARISTOR
Lift one wire of each MOV from the terminal and check with an ohmmeter. If the
reading is less than 100K ohms, the unit is defective.
TESTING THE CONTACTOR COIL
Disconnect all wires from one side terminal of the contactor coil. The ohmmeter
should read approximately 675 ohms for a 208/240 volt unit or 235 ohms for a
120 volt unit. If the circuit is open or shorted, the contactor must be replaced.
TESTING THE ROASTING TIMER COIL
3 elements
7.7 ohms 3 elements 3 PH
L1-L2 15.3 ohms
L1-L3 15.3 ohms
L2-L3 15.3 ohms
TESTING COOLING FAN MOTORS
Test wire 7 to wire 50 on the cooling fan motors. A typical reading on a 120
volt oven is 47 ohms. A 208/240 volt oven will have 183 ohms.
NOTE: These readings are for two fans connected in parallel. A new replacement
fan will read double.
TESTING BLOWER MOTORS
1. Disconnect the blower motor wires from the terminal strip and test with an
ohmmeter to determine whether they are shorted or not. The reading should be
approximately as shown in the table below. Ifa discrepancy exists, check each
motor individually.
12
Voltage i Blower 2 Blowers 3 Blowers
120 Volt 19 ohms 9.5 ohms 6.3 ohms
208/240 Volt 70 ohms 35 ohms 23.3 ohms
PDF compression, OCR, web optimization using a watermarked evaluation copy of CVISION PDFCompressor

Disconnect all wires from terminal #1. The ohmmeter should read approximately
520 ohms for a 240 volt unit or 140 ohms for a 120 volt unit. If the circuit is open
or shorted, the timer must be replaced.
TESTING THE SET POINT RELAY COIL
Unplug the set point relay from its socket and measure coil resistance. Ohmmeter
should read approximately 17.2K ohms across relay coil contacts.
SECTION E GENERAL VOLTAGE TESTING
Test for line voltage between the following:
Li and L2 on the contactor.
Wires 29 and 50 on the power switch
Terminal 15 and 2 on the timer
Wire 47 on the contactor coil and 25 on the electronic circuit board
Connect one voltmeter probe to wire 47 on the contactor coil and the other to the
following wires in succession:
Wire iO on the power switch,
Terminal 14 on the timer,
Wire 25 on the circuit board.
If an intermittent loss of voltage, or a low voltage condition, the cause must be
determined and corrected.
SECTION F. CONTACTOR TESTS
If the contactor has line voltage on the coil but it is not picked up to close the
power contacts, the coil is failed open and the contactor must be replaced.
