Clean the bed support if required, for example due to clogging, or a change of
medium type in the column. To clean the bottom bed support use the procedure
described for cleaning the adapter bed support using an ultrasonic bath (Servicing
the stainless steel adapter bed support, on page 112)
7
Check the O-ring [607] {411b} for visible signs of damage. If damaged replace it with
a new one.
Reassembling the stainless steel bottom bed support
1
Fit the O-ring [607] {411b} into the groove in the bottom plate [502] for 50 and 70
columns, or the end cell {404} for the 100 column.
2
Fit a new O-ring [606] onto the bed support [302].
3
Refit the bed support [302] onto the bottom plate [502] being careful to align the
holes around the circumference on both parts.
NOTICE
The bed support must be mounted in the position according
to figure A below before the bolts [403] are tightened. Damage
to the bed support can occur if the bed support slides on only
partway, as in figure B below. This implies that the O-ring [607]
{411b} has snapped off the groove in the adapter for the 50 or
70 column, or the end cell for the 100 column. Tightening of
the bolts [403] will cause the O-ring [607] {411b} to be pushed
onto the bed support and damage the bed support.
