→ The vessel support collar must be positioned correctly to ensure smooth operation of the vessel
support clamp. If after assembling the support collar the vessel is not vertically aligned when
located in the clamp, it may be possible to loosen the fastening bolt on the vessel support collar
and realign the vessel whilst it is located in the clamp. Once correctly aligned, the fastening bolt
on the collar must be retightened.
→ Alternatively, remove the vessel and refit the vessel collar (as described earlier), ensuring the
distance from the bottom of the vessel neck to the top of the protruding lugs on the collar is
between 40 and 41mm. (Use the alignment jig or a ruler to ensure this is the case.)
For units manufactured before mid 2010 only
Units manufactured before mid 2010 feature two
extra locking knobs on either side of the clamp.
To further secure the vessel, hand-tighten these
locking knobs until they lightly grip the side lugs on
the vessel support collar.
Note: The locking knobs must be loosened before
the final clamping operation is performed, as the
vessel must be free to move as it is being clamped.
→ It is advisable to make any adjustments to the height of the vessel on the framework at this stage
by loosening the locking knobs on the support clamp and sliding it up or down. Subsequent
adjustments to the height of the manifolds and stirrer support may also be necessary.
→ If using a filter vessel, ensure there is enough space below the vessel to allow the BOV piston to
be fully opened, and the filter plate assembly to be lowered sufficiently to enable the filter cake
to be fully withdrawn from the filter vessel body.
