5. Using 3/8” a hex wrench, loosen and remove the two
pump manifold mounting screws (6).
6. Pull the pump manifold (7) down approximately 4 cm from
the pump housing to clear the transducer.
7. Slide the pump block and piston rod forward until the
piston rod is out of the T-slot (4) on the slider assembly
(3).
8. Remove the four heat sink assembly mounting screws
(8). Pull back the heat sink assembly (9) for access to the
