ProFlow Unit 1. 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.

NOTE

Unit shown in unlatched position to identify bolts.

2. 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.

3. 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 mecha-

nism. Once the unit is slid fully home, it is secured by closing the locking clip.

4. Lift the light shroud for access (if fitted) and plug the electrical connection

ProFlow Fitted from the ProFlow unit into the socket sited on the right hand

side of the ProFlow on the print carriage, (figure below refers).

CAUTION

ELECTRICAL CONNECTION.

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.

Connect the curly pneumatic leads from the pressure mechanism to each

respective left and right pneumatic connector sited either side of the ProFlow

printhead mechanism (figure below refers).

NOTE

If the squeegee paste dispenser option is fitted to the print carriage, before

using ProFlow, ensure that the paste dispenser regulator gauge reads '0'

pressure.

5. Connect the pneumatics and switch the machine to ON. To ensure that the

machine recognizes the ProFlow module, the following indications on the

machine MMI are evident:

a. During the boot up sequence the operator is prompted to fit the ‘ProFlow

cover’.

b. The soft key that previously indicated ‘Paste Load’ now indicates

‘Knead Paste’.
