by turning the pump head drive screw with a flat head screw driver. Look in the left or right panel
to see if the motor drive shaft moves. If it does it is properly installed.
8.5.7 Replace the left / right and lower front panels.

tubing end.

tubing in place.
8.6.5 The tubing must then be pulled free from the wire / tubing management system.
