Working with the unit
Refer to the operating instructions for the fi lling
level of the medium and the immersion depth
into the dispersing element used.
Caution: Burns hazard!
If a dispersing element
is not inserted into the drive fl ange as far as the
mark it can become extremely hot in operation
and thus suffer damage.
So as to avoid unintentional ingress of air into the
medium due to excessively turbulent rotation, the
whole unit can be placed a little off centre in the
stirring vessel.
By using the turning knob (pos. 10) the speed may
be infi nitely varied to meet the requirements of the
medium to be processed.
The idle speed for the drive unit can be adjusted
in the range 3 000 and 25 000 rpm; the value will
be shown on the LED display.
If these conditions are met
the unit is ready for service
when the mains plug has
been plugged in.
The driving unit is switched on by means of the
On/Off- switch (pos. 9).
Also pay attention to the ambient conditions lis-
ted in the “Technical data”.
Assembling the dispersion tool
(Overview fi g. 5)
- Open the knurled screw (pos. 3) so that the th-
read does not protrude into the hole.
- Insert the dispersing element (pos. 2) from
the bottom into the drive unit (pos. 1) as far
as the stop. The shaft will audibly click into
place when a small amount of force is ap-
plied (sprung ball bearing) - depending on
the type of disperser. The dispersing element
is fi tted correctly if the dispersing element is
fl ush with the bottom edge of the drive unit.
-
Attention:
Now secure the dispersing element
by screwing the knurled screw tight (pos. 3).
