This unit is equipped with a venting system
on the top of the furnace. This is for the
removal of fumes from the chamber of the
unit.
Contamination is a major cause of element
failure, therefore, remove all fume forming
material before heating. (e.g. clean cutting
oil from tool steel).
Housekeeping is vital to your electric furnace
– KEEP IT CLEAN. Run your furnace up to
871°C (1600°F) empty occasionally to burn
off the contamination that may exist on the
insulation and elements. Maintain 871°C
(1600°F) for at least 4 hours to ensure com-
plete ashing of foreign materials.
Element life is reduced somewhat by repeat-
ed heating and cooling. If the furnace is to
be used again within a few hours, it is best
to keep it at the operating temperature or at
a reduced level such as 260°C (500°F). We
highly recommend that you replace the ther-
mocouple periodically (once every six
months) to ensure temperature accuracy.
General Cleaning Instructions
Wipe exterior surfaces with a lightly damp-
ened cloth containing a mild soap solution.
