Page 20

NOTICE: During the first few hours of operation you may notice a

small amount of smoke coming off the griddle surface, and a faint odor from the smoke. This is normal for a new griddle and will disappear after the first few hours of use.

CAUTION: ALWAYS KEEP THE AREA NEAR THE APPLIANCE FREE

FROM COMBUSTIBLE MATERIALS.

CAUTION: KEEP FLOOR IN FRONT OF EQUIPMENT CLEAN AND

DRY. IF SPILLS OCCUR, CLEAN IMMEDIATELY, TO AVOID THE DANGER OF SLIPS OR FALLS.

OPERATING INSTRUCTIONS

An understanding of how the griddle sections are controlled will be a valuable aid in loading your griddle.

Each 12-inch section of your griddle is independently controlled by a temperature controller. The temperature control sensor is mounted in the center of each cooking section under the griddle plate.

If the product is loaded directly over the temperature sensor, that section will turn on and the burner will heat the entire cooking section. If the product is loaded to the side, front or back of the temperature sensor, the thermostat will react to the temperature change much slower.

During slow periods with minimal loads, do not load directly over the thermostat sensors as this will unnecessarily turn the burners on and overheat the remainder of the section not being utilized.

Turn the product and continue cooking until it has reached its desired degree of doneness.

Remove the product from the griddle. When reloading the griddle, first use the griddle surface on which a previous load was

not placed. This will help insure the proper griddle temperature.

OPERATION

INITIAL START-UP

Prior to putting any griddle into full time operation at normal cooking temperatures, it must be thoroughly "seasoned" and 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.

Before seasoning the griddle it is first necessary to remove the shipping preservative from the griddle surface. To do this, add a mild detergent to hot water and wash the griddle plate. Rinse with a damp sponge and dry with a clean rag.

To "season" the griddle, set the thermostat dial to 300. Allow unit to come up to temperature and cycle off. Apply a thin coat of high-grade, non-salted vegetable oil to the griddle surface. Rub the oil into the griddle surface with the flat side of a spatula or a towel. Re-coat any dry spots that appear then wait 30 minutes and wipe off any excess oil. Repeat these steps at 350, 400, and 450.

To “dry out” the Griddle, set the thermostat to 250 and turn on the power switch. Allow the unit to cycle at least 15 minutes at this heat level. Reset the thermostat to 350 allowing the same time. Reset the thermostat to 450 and allow the unit to maintain the temperature for a minimum of 4 hours. More time may be required if the unit will be operating in a moist or humid 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.

Page 21

OPERATION CONT’D

NORMAL OPERATION

Each 12-inch section of your griddle is independently controlled by a temperature controller. The temperature control sensor is mounted in the center of each cooking section under the griddle plate.

Turn the griddle thermostat to the desired temperature and allow 30 minutes to preheat. Once griddle has been preheated place product on the griddle and allow to cook.

CAUTION: MOST CLEANERS ARE HARMFUL TO THE SKIN, EYES,

NOTICE: Service on this, or any other, LANG appliance must be

performed by qualified personnel only. Consult your LANG authorized service agent directory or call the factory at 314-678-6315, or www.langworld.com For the service agent nearest you.

WARNING: BOTH HIGH AND LOW VOLTAGES ARE PRESENT INSIDE

THIS APPLIANCE WHEN THE UNIT IS PLUGGED/WIRED INTO A LIVE RECEPTACLE. BEFORE REPLACING ANY PARTS, DISCONNECT THE UNIT FROM THE ELECTRIC POWER SUPPLY.

CAUTION: USE OF ANY REPLACEMENT PARTS OTHER THAN

THOSE SUPPLIED BY LANG OR THEIR AUTHORIZED DISTRIBUTORS CAN CAUSE BODILY INJURY TO THE OPERATOR AND DAMAGE TO THE EQUIPMENT AND WILL VOID ALL WARRANTIES.

DAILY CLEANING

Empty the grease drawer or whenever it is 3/4 full by pulling strait out toward the front. It is easily removed for washing.

Clean the exterior of the appliance with Lang Mfg. Prima Shine (72804-41) cleaner to maintain a gleaming appearance.

Keep the griddle surface clean. After each cooking load, scrape the griddle surface to remove any carbonized grease

WEEKLY CLEANING

Once a week (or when necessary) the griddle surface should be cleaned and reseasoned. Use Lang Mfg Carbon Release (72804-32). Rub with the grain of the metal, being careful not to scrape the splashguard.

Be sure to rinse thoroughly and re-season to prevent rusting and corrosion.

Page 23

MAINTENANCE AND CLEANING CONT’D

CALIBRATION CHECK

Set the griddle temperature to 350F on all sections (it should take approximately 22 minutes to reach temperature).

Let the griddle reach 350F and cycle off and on at least three times. Measure 6” from the left, and 11 1/2” from the front of the plate for the first

checkpoint. This will check the center of the sensor for the first cooking section. Each checkpoint is located every 12” to the right from the last point, and always 11

1/2” from the front. (See illustration below.)

CALIBRATION

A 1/16” flat blade screwdriver with a 2” shaft is required to make adjustments on the thermostat.

Maintain the oven temperature at 350. 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 in crease temperature and

clockwise to decrease temperature (1/8 of a turn will move the temperature 5-7  in either direction).

Reinstall the oven knob and recheck the oven temperature.

ELEMENT REMOVAL

Disconnect power from griddle. Prop griddle plate up. Disconnect power wire attached to heating element terminals. Mark or identify each

wire to ensure correct replacement on new heating element. Inspect for frayed ends, broken strands and grease soaked insulation. Replace as necessary.

Remove the two sheet metal screws securing the thermostat capillary tube clip to the element pan. Pull the clip and the tube down and out of the center slot of the element pan. Take care not to break the capillary tube, as it may be brittle from prolonged exposure to high temperature.

Remove the nuts and washers retaining the element pan and pressure plate. Drop the element pan straight down until studs are cleared and pull forward out of

griddle body. The elements will normally drop down with the element pan and are now accessible for replacement as necessary.

Compare voltage and wattage marking of old element with new one to ensure proper replacement.

Reverse the removal procedure to install the new element. Be sure the nuts holding the element pan are snug as this will assure proper contact between the element and griddle plate. The capillary tube bulb must also be tightly clamped against the griddle plate to obtain proper temperature control.

THERMOSTAT REPLACEMENT

Disconnect power from griddle. Prop griddle plate up. Loosen the two sheet metal screws securing the thermostat capillary tube clip to the

element pan. Gently pull the thermostat capillary tube from the clip. Remove the two sheet metal screws from the rear of the control panel box and pull off

the box cover. Remove thermostat control knob. Loosen and remove the two screws securing the

thermostat body to the front panel. Remove wires from thermostat terminals. Mark for proper replacement.

Reverse this procedure for replacement.

PILOT INDICATOR REPLACEMENT

Disconnect power from griddle. Prop griddle plate up. Remove the two sheet metal screws from the rear of the control panel box and pull off

the box cover. Remove the wires from the pilot indicator. The pilot light is held firmly in place by means of a spring metal speed nut on the back.

Remove the pilot indicator by removing the speed nut and pulling it out through the front. It may be necessary to break the pilot light in two to remover he speed nut.

Install the new pilot light and hold in place with speed nut. Reverse the procedure to reinstall.
