INITIAL START UP
Griddles
Prior to putting any griddle into full time operation at normal cooking temperatures, it must be thoroughly
“seasoned” and dried out. Moisture absorption in the closed spaces, in the insulation and even inside
the heating elements can cause future trouble if not properly treated.
Before seasoning the griddle it is rst necessary to remove the shipping preservative from the griddle
surface. To do this, add a mild detergent to hot water and wash the griddle plate. Rinse with a damp
sponge and dry with a clean rag.
To “season” the griddle, set the thermostat dial to 300°F. Allow unit to come up to temperature and
cycle off. Apply a thin coat of high-grade, non-salted vegetable oil to the griddle surface. Rub the oil
into the griddle surface with the at side of a spatula or a towel. Re-coat any dry spots that appear then
wait two minutes and wipe off any excess oil. Repeat these steps at 350°F, 400°F, and 450°F.
To “dry out” the Griddle, set the thermostat to 250°F and turn on the power switch. Allow the unit to
cycle at least 15 minutes at this heat level. Reset the thermostat to 350°F allowing the same time.
Reset the thermostat to 450°F and allow the unit to maintain the temperature for a minimum of 4 hours.
More time may be required if the unit will be operating in a moist or humid environment.
If the unit is out of use for three or more days, a one-hour preheat schedule should be used, especially
when exposed to high humidity and/or cool temperatures.
TH Hood
After the griddle has been completely seasoned and dried out place hood in standby mode and allow to
hold for a minimum of one hour.
NOTICE: Duringtherstfewhoursofoperationyoumaynoticeasmall
amount of smoke coming off the griddle, and a faint odor from the
smoke. This is normal for a new griddle and will disappear after the
rstfewhoursofuse.

10
OPERATION
General
The suggested time and temperature chart (below) is provided as a guide for the products listed only.
If different temperature settings are to be used, select one side of the griddle and operate at the lowest
temperature. Adjoining sections should be set at progressively higher temperatures.
Do not try to operate the end sections hot and the center sections cool.
ALWAYS KEEP THE AREA NEAR THE APPLIANCE FREE FROM
COMBUSTIBLE MATERIALS.
KEEP FLOOR IN FRONT OF EQUIPMENT CLEAN AND DRY. IF SPILLS
OCCUR, CLEAN IMMEDIATELY, TO AVOID THE DANGER OF SLIPS & FALLS.
Loading the Griddle
Griddle
An understanding of how the griddle sections are controlled will be a valuable aid in loading your griddle.
A mechanical thermostat independently controls each 12-inch section of your griddle. The thermostat
capillary tube is mounted in the center of each 12-inch cooking section under the griddle plate.
If the product is loaded directly over the thermostat capillary tube, that section will turn on and the burner
will heat the entire cooking section. If the product is loaded to the side, front or back of the thermostat
capillary tube, the thermostat will react to the temperature change much slower.
During slow periods with minimal loads, do not load directly over the thermostat capillary tube as this will
unnecessarily turn the burners on and overheat the remainder of the section not being utilized.
Turn the product and continue cooking until it has reached its desired degree of doneness.
Remove the product from the griddle.
When reloading the griddle, rst use the griddle surface on which a previous load was not placed.
This will help insure the proper griddle temperature.
TH Hood
Once the griddle has been loaded properly lower the hood over the product.
Below is a chart and with some basic products the suggested cooking temperatures, and cooking time.

MAINTENANCE & CLEANING
WARNING: KEEP WATER AND SOLUTIONS OUT OF CONTROLS. NEVER SPRAY OR HOSE
CONTROL CONSOLE, ELECTRICAL CONNECTIONS, ETC.
MOST CLEANERS ARE HARMFUL TO THE SKIN, EYES, MUCOUS
MEMBRANES AND CLOTHING. PRECAUTIONS SHOULD BE TAKEN TO WEAR
RUBBER GLOVES, GOGGLES OR FACE SHIELD AND PROTECTIVE CLOTHING.
CAREFULLY READ THE WARNING AND FOLLOW THE DIRECTIONS ON THE
LABEL OF THE CLEANER TO BE USED.
Daily Cleaning
Griddle
Empty the grease drawer or whenever it is 3/4 full by pulling straight out toward the front.
It is easily removed for washing.
Daily, use a clean cloth and a good non-abrasive cleaner to clean the stainless steel body of the
griddle. Wipe the polished front with a soft cloth.
Keep the griddle surface clean. After each cooking load, scrape the griddle surface to remove any
carbonized grease.
TH Hood
The TH hood is a self-cleaning device and does not require any other cleaning.
Do not use any water or cleaning solution on the elements. Clean the exterior of the appliance with a
good non-abrasive cleaner, to maintain a gleaming appearance. Wipe drip shield between hood and
griddle to remove any grease.
Weekly Cleaning
Griddle Surface Care (non-chromium surfaces)
It takes very little time and effort to keep the griddle attractive and performing at top efciency.
If grease is permitted to accumulate, it will form a gummy cake and then carbonize into a hard
substance which is extremely difcult to remove. To prevent this condition, the following suggestions
for cleanliness should be followed:
After each use, scrape the griddle with a scraper or exible spatula to remove excess grease and
food. A waste drawer is provided for the scrapings. If there is an accumulation of burned on grease
and food, the griddle should be thoroughly scoured and reseasoned. Use pumice or griddle stone
while the griddle is warm.
Do not use steel wool because of the danger of steel slivers getting into the food.
TH Hood
It may be necessary after high use to allow the hood to burn off any carbon build up.
With a cold griddle, lower the hood and allow the hood to cook for 15 minutes. Additional time may
be necessary for more baked-on grease.
GRIDDLE CARE (CHROME SURFACES)
It takes very little time and effort to keep this Industrial Chrome griddle surface sparkling clean and
performing at top efciency. DO NOT allow grease to accumulate as it will carbonize and become
difcult to remove.
To prevent this condition, the following cleaning suggestions should be followed:
1. Remove excess oil and food regularly with a 4” (100mm) wide razor sharp type scraper and wipe
surface with a damp cloth if desired.
2. Followingthescraping,forendofthedaycleaning,adampclothandanon-silicated,non-abrasive,
non-chlorinated cleaner such as Bon-Ami may be used to wipe surface clean, followed by wiping
with clean wet cloth.
3. Follow daily cleaning steps for Non-Chrome Surfaces.
CAUTION

12
ON CROME SURFACES:
1. Never use pumice, griddle stones, or abrasives on the surface.
2. Never strike the griddle surface with a sharp instrument or spatula edge.
3. Never use steel wool.
4. Never use commercial liquid grill cleaner on the griddle surface.
5. Abusing the surface voids the warranty.
MAINTENANCE & CLEANING
Griddle
Calibration Check
Set the griddle temperature to 350°F on all sections (it should take approximately 22 minutes to reach temperature).
Let the griddle reach 350°F and cycle off and on at least three times.
Measure 6” from the left, and 11 1/2” from the front of the plate for the rst checkpoint. This will check the center of
the probe for the rst cooking section.
Each checkpoint is located every 12” to the right from the last point, and always 11 1/2” from the front.
(See illustration below.)
Calibration
A 1/16” at blade screwdriver with a 2” shaft is required to make adjustments on the thermostat.
Maintain the units temperature at 350°F.
Without turning the thermostat, remove the knob.
Locate the adjustment screw at the base of the shaft and insert the screwdriver.
Grasp the shaft and turn the screwdriver counter clockwise to increase temperature and clockwise to decrease
temperature (1/8 of a turn will move the temperature 5-7° in either direction).
Reinstall the knob and recheck the temperature.
