7. VALVE SETUP AND CLEANING

7.1 Valve removal.

1. Turn Off or disconnect the fluid pressure the syringe/fluid supply

line from the material reservoir.

2. Switch-Off the control unit.

3. Disconnect all valve cables.

4. Remove the valve from the XYZ table.

5. The valve can be now taken apart for cleaning, refer to section 7.3

for cleaning instructions.

6. After replacing the new valve or new control unit, repeat section 4.2

for setup and section 4.3 for nozzle calibration.

7.2 Installation of new nozzle insert.

1. Turn Off or Disconnect pressure to material syringe.

2. Unscrew the Nut and bushing assembly from the fluid manifold using

the nozzle adjustment tool.

3. Unscrew the nozzle bushing/insert assembly from the nozzle adjustment

nut using the nozzle installation tool.

4. Remove the nozzle insert from the nozzle bushing.

5. Place new nozzle insert on the nozzle bushing with the smaller end

facing outward and screw the assembly back into the nozzle adjustment

nut using provided tools. Caution: Keep the assembly in vertical

position while tightening to keep the nozzle seating in the proper

position. Use both tools to help torque the bushing onto the nut.

6. Screw the nozzle assembly unit back onto the fluid manifold and repeat

section 4.3 for nozzle calibration.

7. Re-connect or turn On the fluid supply and pressure. Run the several

purge cycles to remove air bubble from the nozzle replacement. Wipe

and Clean the nozzle tip and the system is now ready for dispensing.

Attention: Inspect the nozzle’s cleanliness under microscope if available.

7.3 Cleaning

WARNING:

• Proper gloves and eye protection must be worn before

disassembling the valve for cleaning.

• Never use wire brushes or machines that cause surface abrasion.

Unsuitable cleaning fluids may damage the valve. Before using

extremely aggressive cleaning liquids or solvents, make sure to

check that all fluid contacting parts are compatible.

The following cleaning tool kit (9800-CLEANKIT-XX) which consists

of the following:

1. Pin Vise

2. Cleaning wires (XX will designate the wire diameter)

3. Cleaning brush

For pre-cleaning purposes, disconnect pressure remove the

dispensing fluid, then connect an empty but clean syringe to the

valve. Use the pressurised air hook up to the syringe to push out any

residue fluid left in the valve out.

The cleaning of the TS9800 Jet Valve can be carried out via:

• Purge fluid path with appropriate cleaning solutions

To remove the remaining dispensed fluid, purge the system with

an appropriate cleaning solution (refer to the material safety

data sheet of the dispensed media and suitable cleaning

solution). For this method, connect a syringe filled with an

appropriate cleaning solution to the valve, then connect the

syringe to the supply pressure. Touch and hold the ‘Purge’ icon

on the controller to purge the system. Run the purge until

the system is clean. Ideally the only material left during the

purging should be the cleaning solution, that would be a good

indicator that the fluid path is clean.

• Thorough Cleaning

1. Perform the above step to purge the system with an appropriate

cleaning solution. Turn the system Off and disconnect all the

connections to the valve.

2. Remove the nozzle adjustment nut (8) by using the nozzle

adjustment tool to rotate it counter-clockwise.

3. Remove the nozzle bushing (6) with the nozzle insert (7) from

the nozzle adjustment nut by using the nozzle installation tool to

rotate it counter-clockwise.
