Working with the unit
Check that the voltage listed on the designation plate matches the
mains voltage. Also pay attention to the ambient conditions listed
in the technical data.
Assembly of the dispersing tool (see Fig. 1 and Fig. 3)
- Open the shaft lock (3) by turning to the left as far as the stop.
- Insert the dispersing element into the collet as far as the stop.
- Lock the shaft lock (3) by turning it to the right until it noticeably
clicks into place. The marks (A) on the shaft lock (3) and mark (B)
on the casing should be over each other when closed.
The distance between the dispersion tool and the vessel bottom
should not be less than 10 mm.
Please observe also the operating instructions of the dispersion
tool to ensure a safe usage.
The entire unit may also be arranged somewhat off centre in order
to avoid any undesired air admission caused by the strong rota-
tional turbulence.
Set the adjusting wheel (1) to the minimum speed before switch-
ing on the instrument. You can read the set speed by comparing
the numbers on the adjusting wheel (1) and the speed table (see
chapter:
Speed Table ).
By using the adjusting wheel (1) the speed may be infinitely adjusted
to meet the requirements of the medium to be processed. The no-
load speed of the
T 10 basic ULTRA-TURRAX
®
driving unit may
be set between 8.000 and 30.000 rpm.
Error correction
The instrument is appropriate for short-time duty (10 minutes
ON /5 minutes OFF ), i.e. the OFF time must be noted. Failure to
observe the ON/OFF time, the instrument can switch off depend-
ing upon load by temperature rise during the dispersing, since the
drive is equipped with an overload safety device, which switches
the instrument off with overload or temperature rise. If the instru-
ment switched off at the
ON/OFF switch, after an appropriate
cooling time the equipment can be restartet.
Note: The instrument does not restart it after responding the
overload safety device automatically, must for cooling at the rocker
switch (2) be switched off.
Maintenance and cleaning
Cleaning:
Drive unit:
The drive unit is maintenance-free but not immune from wear. The
carbon brushes of the motor wear down over the time.
For cleaning disconnect the main plug.
Only use cleansing agents which have been recommended by IKA :
water (containing surfactant) and isopropyl alcohol.
Disassembly (see Fig. 1 and Fig. 2)
• For the disassembly of the dispersion instrument from the clamp (6),
turn handle (5) firstly to loosen the clamp.
• Hold the dispersion instrument with a hand, with the other hand
to pressure on the locking lever ( Fig. 2 ). Now, the dispersing
instrument could be disassemble from the clamp.
The unit is ready for service when the mains
plug has been plugged in.
The driving unit is switched on by pressing the rocker switch (2)
in "
I " position.
