Lower the elements into position, and connect the braids according to the scheme
shown below, using the clip tool provided. The braids must be held tightly to the
element as the clips are fitted:
good contact is essential
; poor contact can lead to sparking and destruction of the
top of the element.
Ensure that the elements are correctly placed: the thin part of the element, and the
tapered section, should ideally be entirely within the heating chamber; the element
should not touch the bottom of the chamber.
Important
-There should be a minimum clearance of 10 mm below the bottom of the
element, and a minimum clearance of 15 mm from the sides of the chamber. The
elements should be parallel with the side walls.
Replacements:
Read the section above on initial installation.
Remove the aluminium braids and clips using the clip tool provided with the furnace. Lift
out the old elements and the insulation blocks: handle the insulation pieces with care as
they are fragile.
Carefully loosen and remove the clamps.
Prepare and install the new elements as explained above.
Heat up the furnace to a moderate temperature and ensure that the furnace is
controlling properly, in case the previous element failure resulted from a fault in the
control system.
After installing new elements run the furnace at 1500 °C for an hour. This creates a
protective glaze on the element surface.
