Initial Start Up
Level unit using the adjustable feet under the unit (approximately 1/2" adjustment).
Before using the unit for the rst time, clean and heat for approximately 30 minutes. The grill may
emit a small amount of smoke as the cooking surfaces reach 300-350°F. Do not be alarmed, as
the smoke is caused by oils associated with the manufacturing process and will stop when the grill
reaches 400°F.
Seasoning The Cooking Surfaces
First Time Seasoning
Follow your company/corporate guidelines for seasoning cooking surfaces or
1. Bring the grill to 300°F and leave it on while doing the next three steps.
2. Brush the cooking surfaces with a release agent. If using an aerosol agent,
rst apply into a cup and then brush onto cooking surface.
3. Let sit for 20 minutes, and then wipe clean using a warm damp cloth.
Daily Seasoning
The grill should not require much seasoning while in use. In most cases, brush a light coating of the
baking release agent in the morning and occasionally throughout the day will be enough to prevent
any sticking. It is not necessary to spray before grilling each item.
MANUAL CONTROL OPERATION
Setting The Temperature
The thermostat control knob is used to set the temperature to your requirements. The maximum set
point is 550°F (288°C), the minimum set point is 175°F (79°C). See Knob Settings.
Setting The Timer (Timer Models Only)
(9 MIN. 59 SEC. MAX)
The timer may be factory pre-set. If changes are required follow these simple steps:
1. To increase time, press and hold the (UP) button.
The Start/Stop button can now be used to increase the cooking time.
2. To decrease time, press and hold the (DOWN) button.
The Start/Stop button can now be used to decrease cooking time.
Knob Setting
Knob Position Approx. Temp
1-2 175°F / 79°C
3 200°F / 93°C
4 250°F / 121°C

9 500°F / 260°C
10 550°F / 287°C
On/off Rocker Switch
(Timer Models Only)
The switch turns the unit on and off. The switch has three positions:
With the switch in this position, both top and bottom platens will heat.
With the switch in this position, neither platen will heat.
With the switch in this position only bottom platen will heat.

6
Daily Operation
Always allow 30 minutes of preheat time before loading the unit with product. Failure to allow
sufcient preheat time will result in unsatisfactory cooking of the rst load.
Check the power cord to insure that it is plugged into a proper outlet.
Check that the switch and thermostat control are turned on.
Set the unit's ON/OFF rocker switch to desired position.
Set the thermostat control knob to desired temperature.
Operating Hints And Safety
Disconnect power to the unit with the switch at the end of each day of operation.
Do not leave the unit in operation without an attendant.
Turn thermostat down to 200°F (93°C) during idle periods. It will take only a few minutes to regain
operating temperature.
Use spatula to push excess grease into grease drawer after each load of food is cooked. This will
reduce smoking of hot grease and carbonizing.
Do not leave the unit at high temperature when not in use or during idle periods. This will cause food
particles and grease lm to carbonize.
"Season" cooking surfaces with non-salted vegetable oil to reduce product sticking.
Monthly Lubrication/Inspection
Apply two (2) drops of non-toxic mineral or vegetable oil to counter balance shoulder rivets and plastic
spacers.
Check and clean brass rollers to make sure they are rolling and not sliding on the cam
surfaces of the counterbalance.
Check the bolts, screws and nuts, tighten if necessary.
Cleaning
Begin cleaning procedure by using the operating procedures within your organization, or follow the
steps below:
1. If particles adhere to the cooking surface during the day, scrape them off with a spatula.
NOTE: It is best not to let food cook onto the grill, as food build-up on the grill will increase
sticking and smoking. In addition, carbon may build up on the grill surface and reduce the
cooking efciency.
Carbon Buildup: A black matter that forms on or near the cooking surface. Generally this is a
combination of: releasing agents, oils, food particles etc. ,that have cooked to the surface. After a
period of time without cleaning, this will reduce performance and material may start aking off. When
that happens, follow the "Carbon Cleaning" procedures.
2. At the end of the day, wipe down all surfaces with a warm, damp cloth and mild detergent, then
dry.
Carbon Cleaning
When carbon build up occurs, use a carbon removal agent (safe for aluminum surfaces) according
to the instructions provided with the cleaner. When this process is complete, you must re-season the
grill according to your company/corporate guidelines, or the seasoning instructions in this manual.
DO NOT IMMERSE OR LET THE UNIT STAND IN WATER.

7
DO NOT HOSE DOWN THE UNIT OR THE TABLE/COUNTER IF THE UNIT IS ON THE TABLE/
COUNTER.
KEEP AWAY FROM RUNNING WATER.
DO NOT USE SHARP OBJECTS TO REMOVE CARBON BUILD-UP.
DO NOT USE ICE ON THE COOKING SURFACE!
BEFORE CLEANING MAKE SURE POWER IS TURNED OFF, UNIT IS UNPLUGGED AND IS
NOT TOO HOT.
While holding top lid with one hand, apply only cleaners which are safe for aluminum
and iron surfaces. Wipe with clean sponge or towel until unit is clean.
DO NOT SPLASH FRONT CONTROL PANEL!
DO NOT SPLASH FLEX CONDUIT CONNECTING TOPAND BOTTOM OF THE UNIT.
Remove and empty to clean grease catcher drawer as required using mild detergent and water.
WARNING
Do not use ice or cold water to clean the cooking surfaces when the unit is hot.
The surfaces are cast aluminum or cast iron and may crack or deform under the shock of
rapid temperature change.
Operation Troubleshooting
1. Unit not heating.
A. Check if unit is plugged in correct receptacle.
B. Check incoming power line.
C. Check that the switch is in correct position.
D. Check that thermostat is set to proper temperature.
2. Top platen not heating.
A. Check that the ON/OFF switch is in correct position.
3. Counterbalance roller not rolling.
