Figure 1-46 Rinse Tubing and Y-Connection Assembly Installed on
Peristaltic Pump and Rinse Station (ASX-520)
To retrofit the rinse station on an ASX-520HS with existing Large Bowl Rinse
Station to the Standard Bowl version, complete the following:
1. Gently pull the rinse station away from the autosampler rinse block.
2. Remove the tubing connecting the rinse station to the peristaltic pump.
Remove the tubing connecting the rinse station to the drain/waste
container. Set the rinse station and all tubing aside, as those items will
not be reinstalled.
3. Connect the Y-tubing assembly to the lowest fitting of the supplied
standard-bowl rinse station (both provided in the upgrade kit), and to
the discharge ports of the peristaltic pump (Figure 1-46).
4. Connect one end of the supplied drain tubing to the drain/overflow
fitting (highest fitting) of the rinse station. Connect the drain tube from
the rinse station to a suitable waste container, ensuring that the end of
the drain tube does not become submerged below the waste liquid
level, as that condition will impede proper drainage. Note: This length
of tubing may be cut to accommodate your specific
position/arrangement.
5. Gently push the Standard Bowl Rinse Station into place onto the rinse
station holder block (mounted on the autosampler front cover) as
shown in place in Figure 1-45.
6. Replace the peristaltic pump input rinse tubing (suction tubing
connecting the input of the peristaltic pump to a rinse solution supply
container) with a single length of tubing, found in the completion kit, as
shown in Figure 1-46 and Figure 1-47. Leave one peristaltic pump
channel input connection open to the atmosphere to allow air to be
drawn in through one channel, while rinse solution is drawn in through
the other channel (Figure 1-47).
