General Cleaning Instructions

Wipe exterior surfaces with lightly dampened cloth contain-
ing mild soap solution.
A few simple procedures will help insure that your furnace
will give you long service.
1. Keep the chamber clean; this furnace is capable of
achieving temperatures which will cause vaporization
of many materials. In turn, these vapors can react with the
heating elements, the insulation, or other materials you
have placed in the chamber. In many instances this
reaction is detrimental to operation.
2. Clean exterior surfaces with lightly dampened cloth
containing mild soap solution.
3. Occasionally check the electrical connections in the
control section. Repeated heating and cooling can cause
terminals to loosen.
4. The type B thermocouple used in this furnace is
matched to the temperature controller. It is possible that its
calibration can drift, particularly when operated near
the upper temperature limit, and especially in the
presence of contaminants. It is a good idea to inspect it
at regular intervals or when its accuracy is suspect.
5. Check the cooling fans at regular intervals to be sure
they are functioning properly and are not obstructed.
