A. INSTALLATION OPTIONS & KIT AVAILABILITY
IMPORTANT
IT IS THE CUSTOMERS RESPONSIBILITY TO REPORT ANY
CONCEALED OR NON-CONCEALED DAMAGE TO THE FREIGHT
COMPANY.
If the installation will require two or three ovens to be stacked, you
must use the separately-available Stacking Kit (P/N T2114STACK).
One Kit is required for a two-stack, while two kits are required for a
three-stack. Stacking more than three ovens is not permitted.
Wherever the Stacking Kits instructions are different from those listed
below, follow the instructions provided with the Kit.
2. Installing the Conveyor End Trays - see Figure 3.
a. Press one of the conveyor end trays down over the end plate
of the conveyor frame.
b. Fasten the end tray in place with one of the supplied 8-32x3/
8 screws.
c. Repeat the above steps to install the second end tray at the
opposite end of the conveyor frame.

CAUTION
THE SUPPLIED LEGS AND THE END TRAYS MUST BE FASTENED

C. ELECTRICAL CONNECTION
IMPORTANT
Wiring diagrams for the oven are provided at the back of this
Manual.
The electrical connection to the oven requires a circuit breaker/
fused disconnect. Consult applicable IEC/CEE and local code
requirements to determine the rating of the breaker/disconnect.
Electrical specifications are listed on the ovens serial plate (shown
in Figure 4) and on the wiring diagrams at the back of this Manual.
The oven must be electrically grounded in accordance with current
IEC/CEE and local code requirements. The location of the
equipotential ground lug is shown in Figure 5.
Consult all applicable IEC/CEE and local codes for further electrical
connection requirements.
Figure 4
B. ASSEMBLY
1. Installing the Legs - see Figure 2.
a. Carefully tilt the oven onto its rear side. The front (controller)
side should be facing directly upwards.
b. Thread the four legs into the four holes provided on the bottom
of the oven. Tighten them until they are secure.
Serial plate
2
1. Before proceeding with the electrical connection, check that the
electrical supply matches the ovens requirements. Refer to the
serial plate (Figure 4) and to the electrical specifications shown
on the wiring diagrams at the back of this Manual.
WARNING
ENSURE THAT BOTH THE CIRCUIT BREAKER/FUSED DISCONNECT AND THE POWER ON/OFF (I/O) SWITCH ARE IN
THE O (OFF) POSITION BEFORE PROCEEDING.
WARNING
ENSURE THAT ANY PACKING MATERIAL RESIDUE HAS
BEEN REMOVED FROM INSIDE THE OVENS COOKING
CHAMBER.
2. Single-phase ovens only:
Check that the appropriate receptacle is available for the
power cord plug.
Insert the power cord plug into its receptacle.
3. Three-phase ovens only:
Remove the two screws that hold the rear cover panel in
place; then, remove the cover panel.
Insert the end of the electrical supply through the connector
shown in Figure 5.
Attach the electrical supply wires to their terminal block
connections, as shown in Figure 5.
Secure the supply wires to the floor of the electrical
compartment using the supplied cable clamp. The wires must
not interfere with the drive chain and sprocket. See Figure 5.
Secure the supply as it passes through the connector on the
outside wall of the oven.
Replace the rear wall of the oven and fasten it in place.
4. All ovens:
Connect an equipotential ground wire to the lug shown in Figure
5. The equipotential ground connection must meet current IEC/
CEE and local code requirements.

III. OPERATION
A. Location and Function of Controls
This section provides a basic description of the oven controls, their
location, and the functions they perform. The operator MUST be familiar
with the controls. Refer to Figure 6.

2. Conveyor speed control knob
Adjusts the speed of the conveyor. This controls the bake time.
1 is the minimum speed setting, which produces the longest
available bake time.
9 is the maximum speed setting, which produces the shortest
available bake time.
3-4. Upper and Lower temperature adjustment knobs
Adjust the temperature settings of the upper and lower heating
zones.
1 is the minimum temperature setting, which sets the heating
zone to the lowest available temperature.
9 is the maximum temperature setting, which sets the
heating zone to the highest available temperature.
B. Operation Procedure
1. Adjust the position of the draft curtains at the ends of the cooking
chamber (if necessary). This procedure is described in detail in
Part D, Draft Curtain Adjustment, in this section.
IMPORTANT
When cooking at very high temperatures (a setting of 8 or higher
on either temperature adjustment knob), the oven should be preheated for at least 10 minutes WITH THE DRAFT CURTAINS IN
THE FULLY-LOWERED POSITION. After pre-heating, the curtains
may be repositioned as required.
2. Restore electrical power to the oven at the circuit breaker/fused
disconnect.
3. Switch the Power On/Off (I/O) Switch to the ON (I) position.
4. Adjust the bake time (if necessary) by turning the conveyor speed
control knob. Adjust the upper and lower temperature settings (if
necessary) by turning the temperature adjustment knobs.
5. Allow the oven to pre-heat for at least 10 minutes.
6. Load the entrance end of the conveyor with the food product. The
motion of the conveyor will move the food product into the cooking
chamber.
C. Shutdown Procedure
1. Switch the Power On/Off (I/O) switch to the OFF (O) position.
2. Wait for the ovens cooling fan to turn off.
3. Disconnect electrical power to the oven at the circuit breaker/fused
disconnect.

D. Draft Curtain Adjustment
The draft curtains may need to be repositioned to provide adequate
clearance for some food products. The curtains should be positioned
to prevent drafts into the oven, and heat loss into the environment.
The draft curtains can be removed from the oven to permit the maximum
vertical clearance above the conveyor.
WARNING
BEFORE ADJUSTING THE DRAFT CURTAINS, SWITCH THE
POWER ON/OFF SWITCH TO THE OFF (O) POSITION.
WHEN REPOSITIONING THE CURTAINS:
WEAR A HEAVY OVEN MITT.
DO NOT REACH INTO THE OVENS COOKING CHAMBER!
See Figure 7.
1. To reposition the draft curtains:
a. Loosen the two screws that hold the draft curtain in place.
b. Slide the curtain to the desired clearance above the conveyor.
c. Tighten the two screws to hold the curtain in place.
d. Repeat these steps for the curtain at the opposite end of the
oven.
2. To remove the curtains from the oven:
a. Remove the two screws that hold the draft curtain in place.
b. Remove the draft curtain.
c. Repeat these steps for the curtain at the opposite end of the
oven.

E. Daily Cleaning
WARNING
WHEN CLEANING THE OVEN:
NEVER USE PRESSURIZED WATER.
NEVER USE A CLEANING SOLUTION OTHER THAN SOAP
AND WATER ON PORTIONS OF THE OVEN THAT COME
INTO CONTACT WITH FOOD PRODUCTS. THESE AREAS
INCLUDE THE CONVEYOR BELT AND END TRAYS.
NEVER APPLY ENOUGH LIQUID TO STAND IN PLACE ON
THE OVEN. LIQUID INSIDE THE OVEN WILL CAUSE A
SEVERE ELECTRICAL HAZARD AND MAY OTHERWISE
DAMAGE THE OVEN.
CAUTION
DO NOT clean your oven using abrasive cleaners or pads. Both will
scratch and dull the finish.
1. With the conveyor running, use a brush to clean any crumbs off
the conveyor into the crumb trays.
2. Switch the Power On/Off (I/O) switch to the OFF (O) position,
and wait for the cooling fan to turn off.
3. Disconnect electrical power to the oven at the circuit breaker/fused
disconnect.
4. Allow the oven to cool.
CAUTION - HOT SURFACES
DO NOT TOUCH HOT SURFACES ON THE OVEN, OR REACH
INTO THE COOKING CHAMBER, UNTIL THE UNIT HAS
COOLED THOROUGHLY.
5. Clean the fan grill on the front of the oven using a stiff nylon brush.
6. Clean the end trays USING SOAP AND WATER ONLY and towel
them dry. If necessary, the end trays can be removed for cleaning
by removing the screws that hold them in place. See Figure 3 (in
Section II).
IMPORTANT
If the end trays are removed for cleaning, they must be replaced
prior to operating the oven.
7. Slide the end crumb trays out from underneath the entrance and
exit ends of the conveyor. See Figure 8.

9. Clean all three of the crumb trays using a commercial oven cleaner.
If necessary, towel them dry.
10. Replace the center crumb tray in the oven as shown in Figure 8.
IMPORTANT
Proper positioning of the center crumb tray is REQUIRED for proper
cooking. Ensure that the tray is replaced inside the conveyor frame,
as shown in Figure 8, and NOT on the floor of the cooking chamber!
11. Replace the two end crumb trays.
12. Clean the outside of the oven using a damp cloth with EITHER
soap and water OR a stainless steel cleaner. Use caution to ensure
that liquids do not enter the oven during cleaning.
