Lock the clamp in place with the fastening clip.
This is done by hooking the bolt of the fastening
clip into the retaining recess of the clamp and then
snapping the clip shut.
Visual inspection of the O-ring through the opening
at the front of the clamp should indicate a witness
line where it seals against the lid flange.
→ There should be minimal movement of the vessel and lid when clamping them together. If
signifcant movement is observed (either sideways or vertically), it is likely that the vessel support
collar is incorrectly positioned on the vessel neck. You will need to remove the vessel from the
vessel support clamp and reposition the vessel support collar.
See Section 6.1.6 on page 13 – Locating the vessel into the framework, for reference.
❖ The vessel support clamp can be adjusted by screwing the
bolt on the fastening clip in or out to tighten or loosen
the grip. This is best done when the clamp is open.
Never use too much force when locking the vessel support clamp as this may damage the vessel.
