4.2.1.4 Pump and pump flow symbols
Figure 32 represents the reagent pump. The top arrow indicates the pump flow direction.
The other two upper lines refer to the rinse water lines attached to the wash reservoir in
the sampler. The wash line is connected to the bottom nipple of the wash reservoir.
4.2.1.5 Reagent line representation
The reagents and sample lines are represented by a straight line crossing the rectangle
(Figure 33). The specified color is the color of the tabs of the pump tubes to use for that
line. All pump tubes have different color tabs on each side to indicate that the tubing has
a certain inner diameter. The direction of pump tube installation is not critical (Figure 34).
