View the platen temperature:
To view the unit’s actual temperature by pressing
the Logo button. The window will display the
platen temperature and the corresponding
indicator light is on. Press the product button
“1”&“2” to view the top and bottom temperature
in turn.
Flat Grill Mode:
Press top heater button, located on the right of
display window, to turn off the top platen and the
top heating indicator light is off simultaneously,
activate the bottom platen only. Press the button
again, top platen is activated accordingly.
Cooking Instructions:
1. Start up the unit by placing the power switch into
the ON position. The heating indicators, located on
the left of window, turn red and the letters “L o” will
display in the window. This indicates the unit is in a
warm-up mode. Press one of number product
buttons and the LED above it will light. If the platen
temperature is higher than the preset temperature
and the window will display “HI”, that means to cool
down the platen. When the preset temperatures
are reached, the heating indicators will turn green
and the display window will show time of the
selected product button.
NOTE: Initial warm-up time is approximately 20 minutes .
2. Place product on the cooking surface and close the
lid.
3. Press the product button for this product and let the
display time countdown to “0” at which time the
unit will beep. To turn off the alarm, press the
product button again.
NOTE: To cancel a program early, just press the product
button and hold for 2 seconds.
4. Raise the lid until it stays put at the proper position
and remove the food. Using a spatula, scrape
residue into the grease tray.
5. Turn the unit off when it is not in use.
NOTE: When not in use it is recommended that the lids be
closed to save energy.
Initial Start-Up
1. Place unit on table
2. Before using the unit for the first time, wipe
down the exterior and toasting area with a damp
cloth.
3. Take to a well ventilated area and heat for
approximately 30 minutes.
4. Brush off any debris from the toasting surface.
NOTE: The grill may emit a small amount of smoke as the
cooking surfaces reach 512°F (266°C). Do not be alarmed, as
the smoke is caused by oils associated with the manufacturing
process and will stop when the burn off is complete.
If the cooking platen is made of carbon steel and it may look
blue because the cooking surface produced oxide film after
heating in production. That is normal, do not affect usage.
Seasoning the Cooking Surfaces
First Time Seasoning
Follow your company/corporate guidelines for
seasoning cooking surface, or
1. Bring the grill to 300°F (149°C) and leave it on
while doing the next three steps.
2. Brush the cooking surfaces with a release agent.
If using an aerosol agent, first 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, brushing a light coating of the
release agent in the morning and occasionally
throughout the day will be enough to prevent any
sticking. It is not necessary to brush before grilling
each item.

DO NOT IMMERSE OR LET THE UNIT STAND IN
WATER. DO NOT HOSE DOWN THE UNIT. KEEP
THE UNIT AWAY FROM RUNNING WATER.
DO NOT SPLASH THE CONTROL HOUSING!
DO NOT SPLASH THE CONDUIT CONNECTING THE
TOP AND BOTTOM OF THE GRILL!
DO NOT USE ICE ON COOKING SURFACE!
Daily Operating Hours
1. After each cook cycle remove all grease and food
residues from the cooking surface with a spatula. The
spatula should have rounded corners to prevent the
cooking surface from being scratched or marked.
2. Wipe cooking surface with a damp cloth if necessary to
minimize grease buildup. If sticking begins to happen
on a regular basis, apply a light coat of release agent as
described in the “Seasoning the Cooking Surfaces”
section of this manual.
3. Empty grease tray at least daily or as necessary during
high use periods.
Never use pumice, griddle stones, or abrasives on
platen surface.
Never strike the griddle surface with a sharp
instrument or spatula edge.
Abusing surface voids the warranty.
After Hours
1. Press and hold “SET” button for 4 seconds to activate the
cleaning mode. The window will display “COOL” until
both plates cool to 149°C (300°F) and the window
displays “CLN”.
2. While in the clean mode, remove grease by applying
liquid dish detergent( recommend using Ecolab™ Heat
Activated Grill & Toaster Cleaner)to the cooking surfaces
with a sponge or plastic scrubbing pad.
NOTE: cooking surfaces are still hot.
3. Rinse surfaces twice with a clean damp sponge or cloth.
4. Repeat as necessary.
5. Apply a light coat of release agent as described in the
“Seasoning the Cooking Surfaces” section of this
manual.
6. Use a clean cloth and good nonabrasive cleaner to clean
all non- cooking surfaces including the front displays.
Wipe all surfaces with a soft cloth.
7. Press top heater button to exit cleaning mode.
8. To remove carbon buildup (a black matter resulting from
burnt on food residue, oils, and release agents) from the
cooking surfaces, use an approved carbon removal
agent (aluminum safe) applied in accordance with the
instructions provided with the agent. After this process
the cooking surfaces will need to be re-seasoned
according to the instructions in the “Seasoning the
Cooking Surfaces” section of this manual.
Platen Surface Limited Warranty Exclusions
The grill has been designed to give you many years of cooking reliability and requires minimum maintenance to keep
the surface in its original condition. All platen surfaces are warranted for a period of 1 year against manufacturing
defects to the original owner from the date of installation. This limited warranty is void if it is determined by Prince
Castle or one of its authorized representatives that the platen surface has been misused or abused or subjected to the
following situations:
1. Improperly installed.
2. Incorrect voltage applied to unit allowing the surface to overheat and discolor.
3. The misuse of any instrument or tool which scratches or makes indentations in the surface which could
cause the surface to peel, flake, or chip off.
4. The use of any chemical or abrasive cleaning solution, griddle brick, stone, screen or other cleaning
products which could damage and affect the performance of the platen surface.
5. The neglect of daily routine maintenance to the platen surface.

600-C602 RevB_EN 8/ 14

Spring Adjustment
NOTE: The spring setting which holds the top housing in the up position is set at the factory and should
provide many years of use without the need of adjusting.
After an extended period of time the top housing may not maintain its original setting, therefore the spring
tension can be adjusted by loosening and tightening the screws on the back of the unit. The detailed steps as
below:
1. Unscrew the screws marked in
circles with screwdriver and take
the cover off.
2. Insert the screwdriver into the hole on the
collar and hold on, then using a hex wrench
(size 3/16), loosen the set screw. To tighten the
spring, turn the screwdriver at a proper angle
following the arrow.(turn in the opposite
direction to loosen the spring), then tighten
the sew screw.
3. Put the cover back and attach the screws.
Note: to get the proper spring pretension force,
may need to repeat the operation one or several
times.
