Element Fitting and Replacement - 1400 °C Models
Replacements: see section 6.7. If at any time the power limit has been increased, reset
it to its original value (see section 10.0 at the back of this manual for the original value).
New elements must not be mixed with aged elements. If a single element fails in an
aged set of elements then replace with a new set. The remaining aged elements can be
used as spare parts in the future.
Disconnect the product from the electrical supply.
Remove the products end panels to gain access to the element connections.
The elements are expensive and fragile and can be damaged by contamination: handle
them with care and keep them clean.
Replacements only: make a note of the actual braid and cable connections to the
elements. Disconnect the clips with the special tool provided (or with finger pressure,
depending on the type of clips supplied), lift off the braids and carefully withdraw each
element. See fig. 5.
Carefully insert the new elements into the product.
Attach the connection braids according to the note made above or to the appropriate
diagram, fig. 6. Use the special tool (or finger pressure) to fit the clips. Take care that
adjacent clips do not touch each other.
Replace the products end guards and connect the product to the electrical supply.
If aged elements have been replaced, reset the product power limit.
