Fitting the standard work tube in an EST/EZS furnace. (No tools required.)
The fitting of the work tube is as follows with reference to Figure 2-3. Please note that
standard work tubes are also referred to as tubes suitable for working in air. They are 150mm
longer than the heated length of the furnace (see Table 9-1 page 24). Read section 5.2 before
fitting the work tube.

Release the top fixing clips item 4 in Figure
2-9; lift the lid by the handle (1).

Place the work tube into the bottom half of
the furnace in the tube adaptors, between
the work tube end stops (5). Note that the
work tube might be a tight fit when it is
new and may need to be twisted backwards
and forwards slightly as it is placed.

Lower the lid by the handle and refasten the
clips.

Note in Figure 2-3 the right hand furnace
end guard (8) is not shown so that the tube
adaptor (3) and tube end stop (5) can be
seen. It is not necessary to remove the
guards to fit the work tube.
