Control Operations
Rocker (Power) Switch
Keypad and Display
When placed in the ON position, the rocker switch allows control
panel operation. The power switches are located on the front
panel.
Indicator Light
The lights on the front panel indicate when the heaters are
operating.
Heating Zones
Each half of the lower (12") cook surface is referred to as a
zone. Each upper cook surface is referred to as a platen. Within
each zone and platen are three independent electrical heating
elements. The elements operate independently to assure an
even temperature throughout the cooking surfaces.
Release Material (units with upper
platens only)
Release material completely covers the upper platen cooking
surface. To attach the release material, insert thetwo metal rods
through the envelopes on each side of the release material. Put
the release material into position and fasten the rods using the
springs to secure the material into position.
Located on the front panel, beneath each cooking zone, is an
alpha-numeric LED display and a group of keypads used for
operating, programming, and servicing the grill and its
microprocessor control.
The keypads are illustrated with icons, descriptive of their
functions, and referred to in these instructions as follows:
Temperature Controls
Each 12" grill surface is equipped with individual temperature
controls. The lower cooking surface temperatures can be set
manually from 150°-400° F (65°-204°C). The upper platen
cooking surface temperatures can be set manually from 150° 425°F (65° - 219°C). The left and right sides (zones) of the grill
operate independently.
Control Board
This unit is equipped with a microprocessor control,
programmable by the operator.
The display is a visual message center for the user, operator
(maintenance personnel or manager), and the service technician.
Operating Screen and Controls
The VERSION SCREEN is viewed when a grill is powered for
normal operation. It indicates the version of software the
microprocessor is using.

Cook Timers
Each item selection has two programmable cook timers. The first
timer is the cook cycle timer. This timer measures the amount of
time the product should be cooked.
The second timer is an alert timer. This timer can be set to alert
the operator to add seasonings, to turn the product, or to start
warming buns for the cooked product.
For example, item one has been programmed to cook for 30
seconds. The operator wishes to add salt in the middle of the
cook cycle. Timer two should then be programmed for 15
seconds. Once the cook cycle begins, a tone will sound 15
seconds after the first timer starts. This tone alerts the operator
to raise the platen, season the product and lowerthe platen to
complete the cycle. Press the timer keypad to stop the tone. The
first timer will continue to measure the full 30 second cook cycle.
Atone will sound 5 seconds before the time elapses, and will
continue to sound until the timer keypad has been pressed.
Note: The factory default settings are 30 seconds forthe first
(cook cycle) timer, and 0 seconds for the second (alert) timer.

Gapping Procedures
The gapping procedure is necessary to level the upper cooking
surface. The procedure should be performed during grill
installation and any time that the cook surface appears uneven.
Step 1
The gapping adjustment needs to be performed while the grill is
at operating temperature. Remove the platen shroud and release
sheet.
Step 2
To allow adjustment of the gap pins, loosen the two set screws
located on the side of the front and rear gap slide.
Step3
Raise or lower both gap pins on the front gap slide until they are
flush with the top edge of the gap slide. Repeat this step for the rear
gap slide. Slide the gap slide to the right.
Step6
Step 4
For each grill surface requiring adjustment, place 4 gap blocks on
the grill surface, approximately 2" in from each corner. Slide the gap
slide to the right.
Figure 5.
Step5
Lower the platen assembly. Loosen and slowly move the T-handle
to the left until the gap slide plates touch the grill surface, and
tighten the T-handle.
Wearing proper protection, carefully attempt to raise the gap slide
plate to evaluate which gap pin is in need of adjustment.
With the gap slide plate raised, slowly turn the gap pin needing
adjustment until it makes contact with the grill surface. Repeat
these steps for both gap slide plates.
Step 7
Raise the platen arm and remove the four gap blocks.
Step 8
Lower the platen arm into the COOK position.
Step 9
Wearing proper protection, attempt to rock the platen assembly.
Apply pressure on the thumb screws at opposite corners to each
other as shown in Figure 8.
Step 10
If the unit rocks, adjust the gap pins slightly across the uneven
corners, as shown in Figure 9.
Note: If adjustment is needed, split the adjustment between the gaps
in need.
Step 11
After adjusting, verify the unit for stability.
Step 12
If all adjustments on the platen are correct, and no rocking occurs,
tighten the two screws located on the side of the front and rear gap
slide plate to lock all adjustments from moving.
Mechanical-Electrical Checkout
Step 1
Check the tightness of all screws and terminals on electrical
components.
Step 2
With the power switches off, record the voltage of all supply
circuits at the circuit breakers. Record the voltage of all supply
circuits at the terminal strip on the front of the grill. The volt
readings should match.
Step 3
With the unit properly connected to the supply circuit, place one
rocker (power) switch in the ON position and record the voltage
reading at the terminal strip. Repeat this step for the second
rocker (power) switch. The volt readings should continue to
match. If the volt reading at the terminal strip drops significantly,
the circuit supply is inefficient or the power cord is undersized or
too long.
Note: To conserve energy and for the grill to heat up faster,
have the upper platen in the COOK position.
Step 4
Start the grill. When operating temperatures have been reached,
lower each upper platen into the COOK position. The control will
display "ITEM1".
Step 5
Verify cook timers (if active).
Step 6
Inspect all mechanical fasteners on the lift mechanism. Make
sure there are no loose nuts or bolts. Secure the back panels
and the grease plates.
Step 7
Calibrate temperatures according to instructions on page 9.
Step 8
Verify gap adjustments according to instructions on page 13.
Step 9
Secure all panels and note the condition of the machine's
exterior.
