Extensive testing has shown that the minimum motor speed required to prime
the tubing varies significantly with the size of the tubing. These variances are
shown in Table 9-3 in Chapter 9. If the tubing will not prime regardless of motor
speed, simply press on the pump stator (refer to Figure 3-11) while the stator is
shut and the motor is running. Pressing on the stator enhances the priming
action of the pump. Release pressure after the tubing is primed.
