pages 11 - 12 Wiring Diagram) to see if the griddle is
connected three phase or single phase. All wires,
cords, plugs, receptacles and circuit breakers must be
sized adequately for the full load rating of the griddle as
specified by local codes or, in the absence of local
codes, by the current National Electrical Code
ANSI/NFPA 70 or the Canadian Electrical Code CAN
22.2 as applicable.
The Electric MIRACLEAN
®
Griddle is also equipped
with a grounding lug next to the terminal block. For
proper grounding procedures, see local codes or, in the
absence of local codes, the current National Electrical
Code ANSI/NFPA 70 or the Canadian Electrical Code
CAN 22.2 as applicable.
NOTE:
The connections to the griddle can be changed
in the field from three phase to single phase or from
single phase to three phase. This can be done by
simply changing the wiring at the terminal block. To
change the connections for your griddle, see the wiring
diagram for your griddle on pages 11 - 12.
NOTE:
For griddles rated at 208-240 volts, the
amperage ratings marked on the nameplates of the
griddles are listed at 240 volts as required by UL. If
your griddle uses a 208 or 220 volt system, refer to the
Electric Griddle Specifications on pages 14 to 16 to
determine the full load rating of the griddle.
NOTE:
A hole has been punched in the rear of the
griddle cabinet for a cord or conduit exit. If a cord is
used, the National Electrical Code, UL standards and
most local codes require a bushing or strain relief (not
provided by Keating) to protect the cord.
WIRE SIZE
Use the table below to help determine the proper wire
size for electrical service hook-up. Use the largest amp
value of the three conductors for 3-phase installations
when using the table. The amperage values for a
product can be found on its serial number tag. Consult
the National Electrical Code Handbook for additional
information or to help answer questions about wire size
selection.
*For runs greater than 75' up to 125', use the next wire
size larger to keep the voltage drop to less than 3%.
For runs greater than 125', consult the National
Electrical Code Handbook to help determine the proper
wire size.
**2/0 wire ambient temperature must be kept at less
than 104°F (40°C).
III OPERATING
CONDITIONING THE
GRIDDLE
The MIRACLEAN
®
Griddle plate has been “seasoned”
at the factory. The chrome surface when heated
creates a thin layer of chrome oxide which acts as a
releasing agent for food products. If you feel you need
to recondition the surface, the following instructions
should be followed:
1. Follow cleaning instructions on page 5.
2. Heat the MIRACLEAN
®
to 400°F for one hour.
3. Lower thermostat to 350°F, allowing the
MIRACLEAN
®
to cool to about 350°F, as is evident
when griddle cycles on or surface thermometer
indicates correct temperature.
4. Lightly coat the MIRACLEAN
®
surface with griddle
oil.
NOTE:
Despite the food releasing properties, the
chrome surface is not a true “non-stick” surface. For
best cooking results and product appearance, use
griddle oil for products that require the surface to be
conditioned.
COOKING
Keating MIRACLEAN
®
Griddles are designed to
provide maximum production efficiency and deliver
high quality food products. Follow cooking procedures
below.
1. For 208-240 Volt Unit: Set ON/OFF switch to “ON”
position. The Power indicating light will illuminate.
For 480 Volt Unit: Rotate thermostat knob from
“OFF” position to desired temperature. The power
indicating light will illuminate.
2. Set the thermostat to the desired temperature and
wait approximately ten minutes for preheating.
Recommended cooking temperatures for various
food products are as follows:
