water.
Ensure all connections between lines
are firm during installation.
Turn off the appliance.
Unscrew filter chambers.
Remove and clean filter insert.

The pump pressure of the immersion pump
in the pump basin can be read on the indi-
cator.
For the proper function of the hydrocyclone
a pump pressure of at least 0.05 - 0.08 MPa
is required.
Check pump pressure.
If the indicator shows less than 0.05
MPa, determine the cause (see Chap-
ter "Troubleshooting").
The outlet pressure of the compressed air
supply pressure reducer can be read on the
gauge.
An outlet pressure of 2.5 bar is required for
proper function.
Check the outlet pressure.
If the gauge shows less or more than
2.5 bar when in operation, correct the
