Initial Start-Up
Prior to putting any unit 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.
R12-ATG
To “dry out” the Hot Plate, set the thermostat dial at 250°F and turn on the power switch. Allow unit
to cycle at least 15 minutes at this heat level. Reset the thermostat to 350°F allowing the same
time. Then reset the thermostat to 450°F allowing the same time. Continue doing this until you
reach 850°F then allow the unit to maintain this temperature for a minimum of 4 hours. More time
may be required if the unit has to operate in a moist 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.
R12-ATH
To “dry out” the French Plate, set the six-heat switch to the rst setting and turn on the power
switch. Allow unit to cycle at least 15 minutes at this heat level. Reset the six-heat switch to
position two and allow the same time. Reset the six-heat switch to position three and allow the
same time. Continue doing this until you reach position six (6) then allow the unit to maintain the
temperature for a minimum of four (4) hours. More time may be required if the unit has to operate
in a moist 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.
NOTICE During the rst few hours of operation, you may notice a small amount
CAUTION
of smoke coming from the unit, and a faint odor from the smoke. This is
normal for a new unit and will disappear after the rst few hours of use.
Operation
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.

Cleaning & Maintenance Procedures
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.
The unit 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: Any cleaner used should be marked “SAFE ON ALUMINUM”.
Keep-drip pans under Add-A-Section Top plates clean.
Keep hotplate surfaces clean.
Outside of unit and top should be kept clean.
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 highly perfected machinery, to insure best
results and continued high operating efciency.
Calibration
Calibration Check
Place thermometer or thermocouple in the center of Hotplate.
Set thermostat to 350°F.
Allow the Hotplate 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” at blade screwdriver with a 2” shaft is required to make adjustments on the thermostat.
Maintain the oven 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 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.
