3. Fit the pressure mechanism part of the ProFlow unit to the ProFlow print-
head mechanism bearing block by means of the two securing bolts.
Tighten using a 5mm Allen key.
4. Ensure that the locking clip on the pressure mechanism is pressed over to
the right and clicks into place, as shown in the figure below. This ensures
that the locking clip is in the correct position to secure the transfer head.

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.

10. Remove the ProFlow pressure mechanism and transfer head.
11. Loosen the four captive screws securing the ProFlow printhead mecha-
nism to the print carriage using a 4mm Allen key. Carefully remove the
mechanism from the print carriage.
12. Placing the unit on a secure surface, slacken off the four screws securing
the stepper motor to the support plate.
13. Remove the old belt and fit the new belt in position.
14. Using a cable tie wrap or similar, provide a loop around the top of the
motor body enabling the motor to be pulled using a force meter. Ensure
that the force meter is pulled in the direction which the drive belt is fitted.
15. Pull the force meter until a tension of 3kgs to 4kgs is monitored on the
meter. Tighten the four screws whilst the motor is under tension.
16. On completion re-fit the printhead mechanism to the print carriage and re-
connect all leads to the print carriage.
17. Re-fit pressure mechanism and transfer head to printhead mechanism.
