cleaning!
Make sure water supply (01) is connected, turned on and guaranteed.
Open drain pipe (08, 09), if provided.
Switch over 3-way valve (04) from scavenging air mode to water sup-
ply.
Set the required volume of water on the flowmeter as shown in the ta-
ble (see table Cleaning parameters).
Shut off the water supply again by switching the 3-way valve (04) to
scavenging air mode after injecting the required volume of water.
The injection process has been completed.
