5. Locate and fit the ProFlow transfer head unit to the pressure mechanism
by means of the two locating dowels. Slide the unit onto the pressure
mechanism. Once the unit is slid fully home, it is secured by closing the
locking clip.
6. Connect both curly air lines to the self-seal pneumatic connectors situated
either side of the ProFlow printhead mechanism, figure in Step 2 refers.
7. Connect the ProFlow Paste Level connector to the print carriage, left hand
side, figure in Step 2 refers.
NOTE
a If the squeegee paste dispenser is fitted to the print carriage, before
using ProFlow, ensure that the paste dispenser regulator gauge reads '0'
pressure.
b. This electrical connection informs the machine of ProFlow fitment and
must always be connected whilst the ProFlow unit is fitted otherwise
damage may occur if machine is run.
8. Switch the mains isolator to ON and ensure that the machine recognizes
the ProFlow module fit by displaying ProFlow Uninitialised during the
machine initialisation sequence.
9. Carry out the ProFlow Contact Position Setup in the Calibrations section
later in this chapter.
