Preventative Maintenance
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 el-
ement 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 1600°F empty occasion-
ally to burn off the contamination that may exist on the in-
sulation and elements. Maintain 1600°F for at least 4
hours to insure complete ashing of foreign materials.
Element life is reduced somewhat by repeated heating
and cooling. If the furnace is to be used again within a
few hours, it is best to keep it at the operating tempera-
ture or at a reduced level such as 500°F (260°C).
General Cleaning Instructions
Wipe exterior surfaces with lightly dampened cloth con-
taining mild soap solution.
