Cleaning the air system
Filter units
– If the filter units are only lightly contaminated: clean the outside
surface of the filter units with a vacuum cleaner.
– If the filter units are heavily contaminated: replace them.
Important notes:
– Apply the vacuum cleaner only to the outside surface of the filter units
so that the contaminatory matter does not penetrate deeper into the
filter fabric and reduce the efficiency of the filter.
– The filter units must not be used for more than 1 year. Under severe
operating conditions, the maximum service time must be reduced
accordingly.
– Install only absolutely dry filters. Damp filters promote the growth of
microorganisms.

Wash all components with a lukewarm soap solution and then rinse
thoroughly with water.
Note: observe the instructions regarding cleaning agents in the “Cleaning
the water system” section.
Before starting with the reassembly, check all components for operational
integrity and any defects. Pay special attention to the float switches and the
drain valve (SU11 and DU11 only). Replace defective components.
Reservoir installation
• Insert the reservoir on the drain connection side into the retainer of the
base unit, swing upwards and secure with the retaining latches.
• Push the drain tubing onto the connection on the reservoir.
• Caution! In the case of the SU21/DU21 base units, secure the drain
tubing with a hose clip and close the drain tube with the threaded
cap.
Filter unit installation
• Insert filter unit(s) (FU1 or FU2) from underneath into the retainers of the
base unit. Swing up and secure with the retaining latches.
