Operating the Pump

5.3 Operating the Pump
With the pump set up, adjust all control settings for the pump
motor and start pumping. Figure 5-5 shows fluid flow
directions with respect to motor directions.
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 9-1 in
Chapter 9. If the tubing will not prime regardless of motor
speed, simply press on the stator (refer to Figure 5-3) while
the stator is shut and the motor is running. Pressing on the
stator enhances the priming action of the pump. Release the
pressure after the tubing is primed.

Make sure that the stator is fully latched before motor
power is turned on. If the motor is turning, and the stator is
unlatched for any reason, make sure to keep fingers and
clothing away from the moving rotor assembly until the
motor is turned off and the rotor assembly comes to a
complete stop.
