section of the rotor. Locate into the delivery side w-block clamp. Make sure that there are no twists or kinks in the
tubing after loading as this will adversely affect tube life. If using a long length of tubing it is best to remove the w-

 Replace the transparent guard and secure in place.
 Compressing the spring on the track occlusion pin (picture 9 and 22) will increase the suction height and
performance against back pressure.
