Exterior
The Griddle dimensions are 26” (66cm) Deep, 5 3/8” (13.65cm) High, and width is
dependent on model number.
The griddle surface is constructed of 1” thick highly polished steel to reduce hot and cold
spots, recovery problems, and ensured even heat through out the griddle.
Controls
Each twelve-inch section has its own easy to use solid-state temperature controls with a
temperature range from 175°F to 450°F in 25° increments.
Each twelve-inch section has a set of 6 kW elements for high efficiency, quick recovery and
outstanding performance.
Receiving the Griddle

be noted on the freight bill at the time of delivery and signed by the carrier's agent.
Concealed loss or damage means loss or damage, which does not become apparent until the
merchandise has been unpacked. If concealed loss or damage is discovered upon unpacking,

packing material should be kept for inspection. Do not return damaged merchandise to Lang
Manufacturing Company. File your claim with the carrier.

and strapped to a skid. Remove the cardboard cover, cut the straps and remove the
wood frame.

INSTALLATION OF THE UNIT MUST BE DONE BY PERSONNEL QUALIFIED
TO WORK WITH ELECTRICITY. IMPROPER INSTALLATION CAN CAUSE
INJURY TO PERSONNEL AND/OR DAMAGE TO EQUIPMENT. UNIT MUST BE
INSTALLED IN ACCORDANCE WITH ALL APPLICABLE CODES.
The data plate is on top of the control box. The griddle voltage, wattage,

This information should be carefully read and understood before proceeding
with the installation.
The installation of any components such as a vent hood, grease extractors,
fire extinguisher systems, must conform to their applicable National, State
and locally recognized installation standards.
Cabinet Preparation
Cabinet Base must have cross air ventilation. It does not matter if it is on the ends
or sides.
If vents are not installed, the controls may overheat rendering the griddle
inoperative.
For best results provide a knockout for the control panel a minimum of 4½”-inches
from griddle support surface as on the following pages.
Installing Griddle into Cabinet
Turn the griddle over, taking care not to kink or pinch any sensor wires.
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 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 NFPA No. 70; latest edition (in Canada use: CSA
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.
The griddle can now be connected to power.
