Installing Griddle into Cabinet
Turn the griddle over, taking care not to kink the thermostat capillary tubes.
Set the griddle on the table that it is to be installed in (leaving a hole big enough to
slip the control panel through).
Insert the control panel through the hole and out the control opening of the cabinet.
The hole must be a minimum of 12” from the griddle and such that the control box
can come out of the cabinet 18” for serviceability.
Lower the griddle plate to sit flat in the table opening.
ELECTRICAL CONNECTION
The electrical connection must be made in accordance with local codes or in the
absence of local codes with
STD. C22.1
A power connection box is provided for power connection.
This box must be installed a minimum of 18 inches away from the heating elements
in the cabinet box.
All electrical connections can be made at this box.

Prior to putting any griddle into full time operation at normal cooking
temperatures, it must be thoroughly "seasoned" or 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 first necessary to remove the shipping
preservative from the griddle surface. To do this set 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°. Allow unit to cycle once.
Apply a thin coat of high-grade, non-salted vegetable oil to the griddle surface.
Rub the oil into the griddle surface with the flat side of a spatula or a towel. Recoat any dry spots that appear then wait two minutes and wipe off any excess oil.
Repeat these steps at 350°, 400°, 450°, 500°, and 550°.
INITIAL START UP
NOTICE:
During the first 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 first few hours of
use.

OPERATION
CAUTION:
CAUTION:
The griddle is provided with two thermostats for controlling the middle two feet of
the griddle surface. The outside one-foot of the griddle is not directly heated.
All cooking should be done on the middle two feet of the griddle surface. All
holding should be done on outside one foot of the griddle.
The thermostats are provided with indicator lights that will go off when the griddle
section reaches the set temperature.
Turn the thermostat dials to the desired cooking temperature and allow the indicator
to cycle on and off a minimum of three times before beginning to cook.
If the product is loaded directly over the griddle thermostat the elements will react
much quicker and the unit will heat up faster. If the product is loaded to the sides
of the griddle thermostat then the reaction time for the elements to come on will be
slightly delayed.
Turn the thermostat dial to the off position at the end of the shift.
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 OR FALLS.

MAINTENANCE & CLEANING
Cleaning
WARNING: KEEP WATER AND SOLUTIONS OUT OF
CONTROLS. NEVER SPRAY OR HOSE
CONTROL CONSOLE, ELECTRICAL
CONNECTIONS, ETC.
CAUTION:
The griddle should be thoroughly cleaned at least once a week in addition to the
normal daily cleaning to insure against the accumulation of foreign material.
NOTICE:
Electric equipment is inherently clean and sanitary, but may become unsanitary if
dirt is allowed to accumulate on it. Take advantage of the clean, sanitary features
of electric equipment, give it the regular attention that it deserves the same as any
other highl y perfected machinery, to insure best results and continued high
operating efficiency.
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.
Any cleaner used should be marked: “SAFE ON
ALUMINUM”.
CALIBRATION
Calibration Check
!
Place thermometer or thermocouple in the center of griddle.
!
Set thermostat to 350°.
!
Allow the griddle to Preheat for at least half an hour.
!
Note cycle on temperatures and cycle off temperatures for 3 cycles. (Red indicator
light indicates when oven is calling for heat)
!
After 3 cycles average the temperature. ( Add all six temperatures and divide by 6)
Calibration Adjustment
!
A 1/16” flat blade screwdriver with a 2” shaft is required to make adjustments on
the thermostat.
!
Maintain the oven temperature at 350°.
!
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 and
clockwise to decrease (1/8 of a turn will move the temperature 5-7 ° in either
direction).
!
Reinstall the oven knob and recheck the oven temperature.
