General Usage

Do not use this product for anything other than its intend-
ed usage.

Principles of Operation

The furnace chamber incorporates a heating element that
is embedded into the side walls and top and back of heat-
ing chamber. The ceramic fiber oval muffle with four
heating surfaces creates even heat distribution within the
chamber. The temperature is controlled by a micropro-
cessor control with a type K Chromel/Alumel Thermocou-
ple. A fan is provided in the furnace to provide forced air
cooling for the temperature controller. A door safety
switch removes power to the heating elements whenever
the furnace door is opened.
