
Loosely fit the work tube support boss Figure 2-15 (5), “O” ring (6), clamp ring (7), clamp
(8), extended work tube slide bracket (3) and adaptor plate (4) onto the work tube in the
position shown in Figure 2-14 (approximately 77 to 79mm from the work tube end). Note
that the clamp is on the outside of the bracket and that the gap of approximately 7 to 9mm
on the inside of the bracket is to allow the work tube to expand at high temperatures.

Tighten the compression clamp (8) then adjust the position of the slide bracket until it
begins to support the weight of the work tube. Tighten the screw knobs (9) to hold in place
and check the work tube ends are still supported, if not then readjust.
Note that the position of work tube supports should be checked before each time the
furnace is used
