There are two drain outlets located on the underneath side of the
reagent module. The outlet closest to the front face of the module is
for tray overflow, the other is to drain liquid from the gas/liquid
separator. Drain tubing should be connected to both of these drain
outlets.
Figure 4. Drain outlets
To connect drain tubing to the drain outlet of an AA reagent
module:
1 Cut a suitable length of the plastic drain tubing supplied with
your reagent module.
2 Connect one end of the tubing to the large outlet underneath the
module tray. The tubing should be connected between the inner
and outer rings on the outlet.
3 Place the free end in your waste vessel. Ensure that the tubing is
free of kinks or sharp bends so that the waste liquid will drain
freely into the waste vessel.
NOTE
The end of the tube must be above the surface of the liquid in the waste vessel.
If the end of the drain tube is submerged, possible back-pressure may lead to
unreliable results.
