Preventive 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 element failure, therefore, removes 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° (1600°F) for at least 4 hours to ensure 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 temperature or at a reduced level such as 260°C
(500°F). We highly recommend that you replace the thermocouple periodically (once every six
months) to ensure temperature accuracy.
General Cleaning Instructions
