8.3.1 Pre ‐ purifying
Pre ‐ purifying consists in purging the system with compressed air.
CAUTION! (potential liquid spurts)
During this procedure, liquid droplets may be expulsed!
Users must protect themselves correspondingly.
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.
Step 4: Reinstall the compressed ‐ air 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.
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 by 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 regu ‐
lation.
