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.

4. Remove the nozzle insert (7) from the nozzle bushing (6).

5. Use the provided 2mm hex key to remove the two mounting

screws (5) and pull the fluid manifold (4) from the valve body

(1). Caution: When remounting the fluid manifold, it’s highly

recommended to torque the two mounting screws to 2.5 – 3.0 lb-

in (0.28 - 0.33 N-m).

Note: Perform step 6 only if the tappet seal (3) must be replaced or a

thorough cleaning is required. If the manifold is removed for whatever

reasons on a regular basis the tappet seal should also be replaced on a

regular basis.

6. Remove the tappet seal (3) from the fluid manifold (4) by

inserting the provided tappet seal tool from the fluid manifold’s

outlet hole and slowly push upward on the seal.

• To install a new tappet seal, carefully place the seal in the

centre hole of the fluid manifold so that the small end of the

seal is facing inward. Make sure that the seal is positioned

evenly and centrally to the hole, then slightly push the seal

with your thumb to engage the seal to the hole. Caution: Do

not push the seal all way inside the hole with your thumb.

• Use the nozzle installation tool with the small pin inserting

into the centre hole of the seal. Slowly push the seal into the

centre hole of the fluid manifold until the seal is fully engaged

with a click noise.

7. Using the Phillips screwdriver to remove the plug screw (9) with

O-ring (10), items 9 & 10 come as one piece.

8. Remove the inlet Luer lock fitting (12) with O-ring (11).

Note: Examine O-rings for damage, replace them if necessary.

9. Using the tappet changing tool to remove tappet assembly (2).
