2M-W352: Thermostatic Electric Griddle, 124T - 172T
EQUIPMENT DESCRIPTION
Exterior Construction
The griddle dimensions are 17” (43.18cm) High, 30” (76.20cm) Deep, and width is dependent on the
actual model number.
The Sides, Bottom, and Rear wall are constructed of double wall stainless steel, which allows closer
installation to combustible surfaces.
The griddle surface is made of 1” thick, highly polished steel to reduce hot and cold spots, recovery
problems, warping, and ensure even heat to the edges of the griddle.
Controls
Each twelve-inch section has its own temperature dial that snaps into place to lock in any temperature
from 175°F to 450°F (79°C to 232°C) in 25° increments.
Each twelve-inch section of the griddle is controlled by an area sensitive RTD probe, which can sense
and react to a temperature change of +/- 4°F.
Each twelve-inch section has a set of 6 K.W. elements for high efciency, quick recovery and outstanding
performance
Technical
The 100 series thermostat griddle operates on either 208, 220, 240, 380, 440 or 480V, are shipped three
phase, (unless in specic specications). 208, 220, 240V can be eld converted to single phase.
Minimum clearances: 2” from side and back
NOTICE The data plate is on the right side of the griddle. The griddle voltage,
wattage, serial number, wire size, and clearance specications are on
the data plate. This information should be carefully read and understood
before proceeding with the installation.

Do not install the griddle closer than 12 inches from an uncontrolled heat source (char broiler etc.).
Keep the appliance area free and clear of combustible material and do not obstruct the ow of
combustion or ventilation air.
Electrical Connection
Detach cover on junction box at rear of unit. There is one power supply connection on the 2, 3,
and 4-foot griddles. There are two power supply connections on 5 and 6-foot griddles. Refer to the
power supply chart in the Technical Specication Data portion of this manual (pg 4 & 5), for proper
power supply size.
There is (1) one 1 1/4-inch conduit knockout on 2, 3 and 4-foot griddles located at the rear of the
griddle, through the back and the bottom of the griddle body. There are (2) two 1 1/4-inch conduit
knockouts provided on the 5 and 6-foot griddles. Use a supply wire suitable for at least 90°C/194°F.
This griddle is shipped from the factory set up for a three phase service. On 208V, 220V & 240V the
wiring can be changed in the supply terminal junction box to convert the griddle to single phase.

2M-W352: Thermostatic Electric Griddle, 124T - 172T
INITIAL START UP
Pre-Power On
Before starting the griddle for the rst time, clean the griddle body and cooking surface.
Use a mild soap and water solution, then rinse with clear water and dry.
The griddle is shipped with a protective coating and craft paper covering the cooking surface.
This MUST be removed before heating the cooking surface. After removing the craft paper, the coating
can be scrapped from the cooking surface and then wiped with a dry cloth.
Power On
Set the temperature dials to 200°F (93°C).
Heat the griddle at 200°F (93°C) for 2 hours to evaporate any moisture that may be in the elements.
Wipe surface again with dry cloth to remove any residue that still remains.
After 2 hours at 200°F (93°C), turn the temperature up to 350°F (176°C) for ½ hour.
After the griddle reaches 350°F (176°C) for ½ hour, turn the griddle up another 50°F (10°C) for another
½ hour and repeat this until it is at 450°F (232°C) for ½ hour.
The unit may emit a small amount of smoke as the cooking surface passes the 300°F (148°C) point.
Do not be alarmed as the smoke is caused by oils associated with the manufacturing process and will
stop when the griddle reaches 350°F (176°C).
Seasoning Cooking Surface
The cooking surface must be “seasoned” in order to eliminate product sticking during cooking.
To season, heat the griddle to 250°F (121°C).
Once at 250°F (121°C), coat the cooking surface with non-salted vegetable oil.
Allow the griddle to stand at 250°F (121°C) until the cooking surface looks dry then coat it again.
Heat the griddle to 350°F (176°C) and repeat the procedure.
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.
