2.0 Installation
Ensure that the product is placed in such a way that it can be quickly switched off or
disconnected from the electrical supply.
If the product is supplied with a work tube or any accessories fit these into position.
For optimum temperature uniformity, insulating plugs should be placed in the tube ends
as shown in fig.1. With a long work tube, the stem of the plug assembly should line up
with the end of the tube as in fig.2. Alignment of radiation shields is similar to that of
plugs.
If stainless steel seals with gas inlets are supplied, they are to be fitted as shown in
fig.3; the stem of any insulating plug should touch the seal.
For vertical models with stainless steel seals, a hook and eye arrangement holds the
upper insulating plug assembly.
Horizontal models: if heavy fittings are to be clamped to the end of an extended work
tube they can increase the bending stress at the centre of the tube. Support such
fittings in such a way that expansion of the tube is allowed.
If a metal work tube is being used in the product, ensure that it is earthed for operator
safety.
