Reassembling the plastic adapter bed support
1
Fit the scraper seal [605] and O-ring [604] using the following procedure:
NOTICE
Improper fitting of the scraper seal and O-ring, or damage
caused to either part, may cause leakage. Follow the instruc-
tions carefully.
a
Place the adapter distributor onto some plastic foil on a flat surface. Lubricate
the O-ring on the bed support with 20% (v/v) ethanol.
b
Fit the scraper seal [605] onto the distributor [402]. Ensure that the flat underside
of the scraper seal is placed in contact with the flange of the distributor.

Figure 6.14: Placement of the scraper seal onto the distributor (A) with the flat
surface face downwards until it sits on the distributor flange (B).
c
Fit the O-ring [604] by gently moving it down the distributor a bit at a time around
the circumference. Use 20% (v/v) ethanol for lubrication. This may be achieved
by gently pulling a section of the O-ring out from the distributor wall and moving
it downwards a fraction, and then repeating on an adjacent section of the O-ring
and so on.
The scraper seal can be mounted in a plastic container filled with water
to facilitate the placement of the scraper seal and O-ring and to avoid
trapping air.
Note:
NOTICE
Avoid rolling the O-ring down the distributor as this may
lead to twisting of the O-ring, which may cause leakage.
