Servicing the stainless steel
bottom bed support
Disassembling and servicing the stainless steel bottom bed support
This procedure assumes that the top plate and adapter have been removed from the
column (see Removing the top plate and adapter, on page 49).
1
If the column is used together with the pivot stand (standard for 70 and 100 columns,
accessory for the 50 column), invert the column in the stand (Using the pivot stand,
on page 38). For AxiChrom 50 column in the foot [123-1], unscrew the bolts [123-2]
and lift the column out of the AxiChrom foot and place the column lying down on
the flanges.
2
Remove the bottom plate assembly [C] from the column:
a
Unscrew the six bolts [801] from their holes.
b
There are three additional threaded holes on the bottom plate assembly. Use
three of the removed bolts [801] and insert them into these three holes.
c
Gently screw in each bolt a little at a time to jack the bottom plate assembly (C)
until it slides out from the bottom flange (805).
Figure 6.5: Inserting the bolts to jack out the bottom plate assembly.
3
Remove and discard the O-ring [606] on the bed support [302].
4
Use an Allen key to remove the bolts [403] on the bottom plate [502].
5
Remove the bed support and rinse with water. Inspect it for signs of damage. If
necessary replace the entire bed support.
NOTICE
Always wear gloves when handling the bed supports to prevent
the transfer of fats and other contaminants from your fingers.
