3.
Inspect the heater cavity, and look for molten flux spills. If molten flux is
found, scrape the insulation clean, or replace the soft insulation completely.
IMPORTANT:
Remember that molten flux on the soft insulation could transfer
onto the new element and ruin it rapidly. Ensure that the heater’s cavity is
completely clean before installing a new element.
4.
Carefully insert the new element through the opening on the top of the
heater’s soft insulation. Be extra cautious to not crush the thermocouple tip.
5.
The two element’s leads should run through the matching holes in the bottom
of the heater.
6.
While holding the element in the heater, gently tilt the heater forward, in the
pouring position.
7.
Using thin pliers, gently pull on the two element leads. No need to pull hard;
the idea is to just relieve any compression stress, which could cause
premature failure of the element. (Note that the ceramic connector is not
show on the picture, for clarity.)
8.
Re-install the terminal screws and washers onto the connector (see step 4.2 at
page 44).
9.
Tighten firmly, to ensure a good electrical contact.
10.
Straighten the crucible heater back to the upright position.
11.
Re-install the “Black Ceramic” tube inside the element coil. Make sure to insert
the protruding tip end first. Rotate the cylinder until its tip inserts into the
matching notch in the bottom ceramic disk of the heating element.
12.
Re-install the five ceramic plates.
13.
Re-install the top ring, and fasten its five (5) screws.
