Cleaning: Clean polluted impellers by using compressed air (not in direction of motor bear-
ing)
Positioning: If vibrations occur, slightly loosen hexagon nut, rotate impellers against each
other and fasten hexagon nut; repeat procedure until the unbalance is cancelled (function
check according to chapter 11.2)
Replacement: Replace impellers if they are either damaged or essentially deformed; we
recommend polluted impellers to be replaced rather than to be cleaned
