2b - USING THE CARTRIDGE FILTER ELEMENT
• Release the motor unit.
• Place the filter element (b) onto the motor support (c).
• Fit the adapter disk (a) onto the filter element (b) and fasten the two parts together,
by turning the knob clockwise.
• Fit the motor unit back onto the container-drum.
• We strongly recommend using this filter element when vacuuming dust and
solids; it can be used along with the filter paper bag. This helps keep the
filter element from clogging, and has the advantage of making the disposal
of vacuumed debris quick and sanitary.
3b - USING THE MOUSSE FILTER
• To vacuum liquid substances, use the mousse filter.
