6.1 General

The Lang Electric Cheese-melter can be used to poach, sauté and brown. In addition
to melting cheese on sandwiches, French onion soup, hot apple pie and casseroles, it
may be used for finishing Italian, Mexican and au gratin dishes utilizing less energy
than conventional broilers.

The product is heated with infrared energy provided by quartz heaters. Although
the heating elements are not directly controlled to regulate heat, the exposure of the
product to heat is adjustable. Heat adjustment may be obtained by raising and
lowering the rack position. The shelf positions provide a choice of cooking positions
for a variety of applications. The top position is very hot, and can be used for quick
browning and toasting, with the heat decreasing at each lower position.

In order to change positions, simply slide the rack in and out of the slots provided.

6.2 Operation

Controls are located on the front panel and consist of the following items:

Power Switch

- a toggle switch used to turn the unit on and off.

OPERATING DO's and DON'Ts

DO:

Insure all dishes placed in the cheese-melter are oven safe.
Pre-heat pans in the cheese-melter or on a stove.
Turn products halfway through cooking, as needed.

DON'T:

Do not use the cheese-melter as a cooking or baking device, it is best suited for
finishing dishes immediately pr ior to serving.

Do not use the unit to heat or thaw chilled or frozen product.
Do not place aluminum foil on the rack or bottom shelf. This will reflect heat

and expose components to unnecessary high temperatures.

Do not move rack from one position to another without hand protection.

CLEANING & MAINTENANCE

WARNING: KEEP WATER AND SOLUTIONS OUT OF CONTROLS.

NEVER SPRAY OR HOSE CONTROL CONSOLE,
ELECTRICAL CONNECTIONS, ETC.

CAUTION:

MOST CLEANERS ARE HARMFUL TO THE SKIN,

weaken the element and break the glass.

7.2 Maintenance

ELEMENT REPLACEMENT

Quartz Elements are replaced as follows:

De-energize unit and open power supply breaker.
Remove rack and set to one side.
Remove three (3) screws from each element bracket. Brackets support each end of

the elements. One or both brackets may be removed.
Remove ceramic wire nuts from both ends of the element, label wires as necessary

to allow ease of reconnection.
To check each element, use an ohmmeter and check for continuity from one end of
