G. Furnace and Element Maintenance
G.1 Preventative Maintenance
Once a month, ensure the thermal insulation is not damaged, cracked, or ill-tting. If the
thermal insulation is cracked, eliminate heat loss at these points by sealing cracks with a
blanket insulation of a similar temperature rating.
G.2 Embedding & Patching Elements
If heating elements have exposed wire, use only ATS supplied embedding compound to
secure them.
NOTE: Not all elements require embedding cement. Contact ATS with any
questions by calling +1-724-283-1212.
The following tools are necessary for this procedure:
• Embedding compound powder
• Distilled water
• Tool to mix compound
1. After the furnace is in place and the leads are secure, mix the embedding compound
powder with distilled water so a paste is formed. The paste should be thin enough to go
down into the coils, but thick enough to maintain body.
2. Work the paste down into the groove, making sure it goes between the coils. Smooth
the surface and remove any excess paste.
3. After the coils are embedded, turn the power on to heat the element to approximately
200°C. This will allow the cement to dry quickly and prevents possible coil damage.
NOTE: Do not overheat the coils at this point. If necessary, turn the
power on and o in order to prevent the coils from becoming so hot they
are red. Notice that the compound texture is powdery at this time. The
compound will harden when it is brought up to operating temperature
later.
