EQUIPMENT DESCRIPTION
Lang Model: XL
Electric Clamshell
The Electric Clamshellconsists of an electric griddle base and an electric hood.
Exterior
♦Griddle
Griddle dimensions are 17” (43.18cm) high x 30” (76.20cm) deep x width is dependent
upon model number.
The sides, bottom, and rear wall are constructed of double wall stainless steel that allows
closer installation to combustible surfaces.
The griddle surface is made of 1” thick, highly polished steel that eliminates hot and
cold spots, recovery problems and warping, and ensures even heat to the edges of the
griddle.
♦XL Hood
Hood dimensions (including griddle and legs) are 22¼” (55.88cm) high with hood
lowered, (44¾” [113.67cm] high with hood raised, 31½” (80cm) deep, x 24” (61cm)
wide.
The hood wrap is constructed of stainless steel.
There is a 3” clearance between griddle and hood.
Controls
♦Griddle
Each twelve-inch section has a manual thermostat with a temperature range of 175°F to
450°F in 50°increments.
The thermostat is mounted in a fully enclosed, air-cooled compartment for protection
from heat and grease.
Each thermostat has a pilot light indicating when heating elements are energized. Light
shuts off when griddle reaches set temperature.
♦XL Hood
The XL Hood has an “on/off” toggle switch located in the griddle base control area that
energizes the heater. A tilt switch is integrated in the top of the hood that activates the
heater to “full on” when lowered, standby when raised.
A “on/off” heat indicator lamp is located next to the “on/off” toggle switch.

♦Griddle
The griddle is standard 208/240 dual voltage, 3 phase, for on-site installation to either
208v or 240v. For simple conversion to single phase power connection see the phasing
portion of this manual. This conversion is extremely easy and neither terminates the
Lang warranty nor is chargeable to Lang as warranty service.
♦XL Hood
The hood is standard 208 or 240 single phase. The voltage must be specified when
ordering.
CLEARANCES
Spacing requirements are 2” from the sides and back.

merchandise has been unpacked. If concealed loss or damage is discovered upon
unpacking, make a written request for inspection by the carrier's agent within 15 days of
delivery. All packing material should be kept for inspection. Do not return damaged
equipment to Lang Manufacturing Company. File your claim with the carrier.
Location

help protect the unit from the physical damage normally associated with moving it through
hallways and doorways.
Uncrating
The unit will arrive completely assembled inside a wood frame covered by a cardboard box
and strapped to a skid. Remove the cardboard cover, cut the straps and remove the
wood frame.
CAUTION: THE UNIT IS EXTREMELY HEAVY. FOR SAFE HANDLING,
INSTALLER SHOULD OBTAIN HELP AS NEEDED OR EMPLOY
APPROPRIATE MATERIALS HANDLING EQUIPMENT (SUCH
AS A FORKLIFT, DOLLY OR PALLET JACK) TO REMOVE THE
UNIT FROM THE SKID AND MOVE IT TO THE PLACE OF
INSTALLATION.
CAUTION: ANY STAND, COUNTER OR OTHER DEVICE ON WHICH THE
UNIT WILL BE LOCATED MUST BE DESIGNED TO SUPPORT
THE WEIGHT OF THE UNIT.
CAUTION: SHIPPING STRAPS ARE UNDER TENSION AND CAN SNAP
BACK WHEN CUT.
Remove the unit from skid and place in intended location.
INSTALLING THE LEGS
The XL Hood comes standard with 4-inch stainless steel legs. A optional stand is available.
To install the legs, remove the legs from the grease drawer. Using extreme caution elevate
the griddle 10 inches off the ground and install the legs in the threaded holes provided.
To install the stand, turn the stand so that the legs are sticking strait up positioning the side
with the three holes to the rear. Place the metal spacer on the legs and slide the shelf over
the legs until it rests up against the spacer. Tighten the Allen screws on the shelf so that it is
stationary. If casters were ordered, install the caster onto the threaded stud provided in the
bottom of the leg to the desired height and tighten the Allen screws on the stand. Flip stand
over onto the legs so that the three holes are in the back. Using extreme caution, set the
griddle onto the stand. Using the threaded holes provided on the bottom of the griddle
screw the 5/8 bolt through the stand into griddle.

ELECTRICAL CONNECTION
♦Griddle
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 1 1/4-inch conduit knockout through the back and the bottom of the griddle body is
located at the rear of the griddle. A 3-pole terminal block is provided for service
connections and can be accessed through a removable panel on the back of the griddle.
Use a supply wire suitable for at least 90 degree centigrade.
The griddle is shipped from the factory wired 208/240 dual voltage. Jumper wires on
terminal strip next to the main power supply connection determine the griddle voltage.
For a 208- volt power supply, leave the jumpers in place. For a 240 -volt power supply
disconnect the jumpers to the terminal strip as indicated on the tag.
♦XL Hood
For power connection to the hood, a two pole terminal block is provided next to the
three pole terminal block on the back of the griddle.
The hood is shipped either 208 or 240 volt single phase only. The voltage must be
specified when ordering.
WARNING: MAKE SURE THE MAIN POWER SUPPLY TO THE GRIDDLE IS
TURNED OFF AT THE SOURCE PRIOR TO CONNECTING POWER
TO THE GRIDDLE.
CAUTION: BE SURE THE POWER SUPPLY VOLTAGE MATCHES THE
VOLTAGE SPECIFIED ON THE NAMEPLATE LOCATED ON THE
FRONT OF THE GRIDDLE.
