8.3.2 Rinsing with Purifying Agent
After pre ‐ purification by compressed air, residual liquid may still be present inside the fluid
system (particularly when dispensing high ‐ viscous substances) . You can only remove it with a
flushing procedure. For this purpose, the following agents may be suitable:

Distilled water

Ethanol

Isopropanol (IPA)

Acetone
WARNING! (potential chemical reactions)
Before the start of the procedure, carefully read the safety data sheet of the dis ‐
pensed substance. Ensure compatibility with the cleaning agent. The cleaning agent
itself should not react with any part in contact with the fluid. Consult the manufactur ‐
er in case of need, especially if aggressive material is intended to be used. In case of
need, consult the manufacturer.
Step 1: The dispensing process must be completed. The valve is in closed position.
Do NOT switch OFF the control unit.
Step 2: Separate the compressed ‐ air connection.

The pressure must be reduced to 0 bar.

Disconnect the PP adapter fitting from the cartridge.
Step 3: Replace the used cartridge by a new one. The purifying agent can be supplied.
CAUTION!
All of the connectors must be installed and leak ‐ tight.
Step 4: Reinstall the compressed ‐ air connection as follows:

Place the PP adapter fitting on the cartridge. Rotate clockwise, until it latches in place.

Connect the PVC hose with the KS4 ‐ CK ‐ 6 coupler plug to a compressed ‐ air supply. For
this purpose you require a KD4 ‐ 1/2 ‐ A coupler socket.

Activate the compressed ‐ air supply.
Step 5: Place a container underneath the valve, to collect any liquid dripping out. The
container needs sufficient capacity to contain the purifying agent together with
the solved residual liquid.
Step 6: Initiate the purging procedure by pressing [F1] .
Keep the [F1] key pressed until the procedure is complete and no more liquid
flows out through the nozzle unit.
INFORMATION (automatic closing)
After ca. 2 min the valve closes automatically, in order to protect the actuator.
Alternatively, the procedure can be performed via the RS ‐ 232C interface.
Use the commands VALVE:UP and VALVE:DOWN for this purpose.
Step 7: Separate the compressed ‐ air connection and remove the cartridge.
Step 8: Make sure the collected liquid in the container is disposed of according to local
regulation.
