• Remove the supply unit as described above.
• Place the supply unit onto your working surface in a way that the front
panel is directed towards you.
• The wire bracket which fixes the filter mat is hooked into four recesses;
first unhook at the upper right, then at the upper left.

• For inserting the new filter mat tilt the supply unit to the left. Carefully lift
the lower part of the wire bracket by a small amount with an appropriate

sure that all the air vents are covered by the filter mat and readjust it, if
necessary.

bracket first at the left, then at the right-hand side.
• Recheck that all the air vents are covered by the filter mat.
