12.3.3 Peristaltic pump tubing.
The expected life of the peristaltic pump tubing is one year.
To replace pump tubing:
1. Turn off the sample and reagent pumps.
2. The reagent and sample tubing is connected to the pump tubing
with luer fittings. See Figure 12-6. Disconnect the fittings from
the pump by turning the fitting in the direction of the arrow.
3. Using your thumb and forefinger gently pinch the sides of the
pump cover. Slide the cover upwards to remove it. See Figure
12-7.
4. Using your thumb as shown in Figure 12-8, push the tubing fit-
ting straight outward until the fitting slides out of the socket.
Repeat the process for the other fitting.
5. Remove and discard the pump tubing.
6. Insert the new tubing one end at a time. Tongues on the sides
of the gray fittings at the ends of the tube fit into receiving
grooves in the pump casing. See Figure 12-9. Push the fitting
into place until it clicks. Gently stretch the tubing over the rollers
and insert the other fitting into the receiving socket on the other
side of the pump.
