EQUIPMENT DESCRIPTION

Lang Model: XLH12

12-Inch Electric Clamshell

Controls

The XLH12 Broiler has a power switch located on the right of the pylon mounted control panel. A white indicator light adjacent to the power switch indicates power when power is on. A plunger switch mounted at the center of the control panel, actuated by placing the hood in the up “idle” position, switches between full and idle power settings. A green indicator light indicates when full “cooking” power is set. A standby circuit, consisting of a momentary contact switch and an amber indicator light, allows element power to be reduced to idle when the hood is in the down “cooking” position.

Technical

The broiler, not including the griddle, is standard 208 or 240-volt, single phase. The voltage must be specified when ordering.

NOTICE

Each unit is preheated, tested and calibrated at the factory before shipment. However, due to temperature and climate changes during shipment the unit can absorb moisture and should be dried out before attempting to put it in full operation.

Prior to putting any unit into full time operation at normal cooking temperatures, it must be thoroughly "seasoned" or 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 the initial use of the unit, the element must be thoroughly allowed to dry out. This can be done by cycling the unit on and placing the hood into the down position. Allow the unit to saturate until all vapor and condensation has been eliminated. For best operating results allow the unit to thoroughly dry out for 8 to 12 hours.

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.

During the first few hours of operation you may notice a small amount of smoke coming from the appliance, and a faint odor from the smoke. This is normal for a new oven and will disappear after the first few hours of use.

INITIAL START UP

CAUTION

ALWAYS KEEP THE AREA NEAR THE APPLIANCE FREE FROM COMBUSTIBLE MATERIALS.

KEEP FLOOR IN FRONT OF EQUIPMENT CLEAN AND DRY. IF SPILLS OCCUR, CLEAN IMMEDIATELY, TO AVOID THE DANGER OF SLIPS OR FALLS.

GENERAL

Once the griddle has been loaded properly lower the hood over the product.

Elements must not touch product when clamshell is in the closed position.

MAINTENANCE & CLEANING

WARNING

CAUTION

KEEP WATER AND SOLUTIONS OUT OF CONTROLS. NEVER SPRAY OR HOSE CONTROL CONSOLE, ELECTRICAL CONNECTIONS, ETC.

MOST CLEANERS ARE HARMFUL TO THE SKIN, EYES, MUCOUS MEMBRANES AND CLOTHING. PRECAUTIONS SHOULD BE TAKEN TO WEAR RUBBER GLOVES, GOGGLES OR FACE SHIELD AND PROTECTIVE CLOTHING. CAREFULLY READ THE WARNING AND FOLLOW THE DIRECTIONS ON THE LABEL OF THE CLEANER TO BE USED.

DAILY CLEANING

The XLH12 hood is a self-cleaning device. When the hood is in the down position it will bake off any debris that may accumulate during normal business operation.

Do not use any water or cleaning solution on the elements.

Clean the exterior of the appliance with Lang Mfg. Prima Shine (72804-41) to maintain a gleaming appearance. Wipe drip shield between hood and griddle to remove any grease.

WEEKLY CLEANING

It may be necessary after high use to allow the hood to burn off any carbon build up. With a cold griddle, lower the hood and allow the hood to cook for 30 minutes. Additional time may be necessary for more baked-on grease.
