Switching The Unit On; Permitted Dispersion Tools - IKA T 65 D ULTRA-TURRAX Mode D'emploi

Switching the unit on

Check that the voltage stated on the rating
plate matches the available mains supply vol-
tage. The socket used must be earthed (pro-
ATTENTION!
tective earth contact). If these condition are
fulfilled, the unit is ready for service, after the
mains plug is inserted. Otherwise, safe opera-
tion cannot be guaranteed, or the unit can be
damaged.
Before switching the unit on, the dispersion tool
must be immersed to the minimum immersion
depth in the medium (see "Technical data"). Be-
cause of the suction effect, the clearance to the
base of the vessel must not be less than 30 mm.
Dispersion tools serie S 65 ....
The T 65 D ULTRA-TURRAX
only be operated with dispersing elements from
the S 65 .... range!
A dispersion tool serie S 65....consists of a shaft
and a generator (stator/rotor). The shaft carries
the marking S 65 KG-HH, where KG stands for
the ball bearing and HH for a slide ring seal made
of hard metal. The seal prevents liquid rising up
the shaft and destroying the ball bearing. The top
end of the shaft is in the form of a plug-in coup-
ling. The bottom end of the shaft carries a thread
for mounting the stator. The shaft – running in
ball bearings- carries the rotor.
For the S 65 range, there are three types of gene-
rator, designated G 65 G, G 65 M, G 65 F, where
the prefi x G stands for generator and the suffi ces
G for coarse, M for medium and F for fi ne.
ATTENTION!
The appropriate generator must be used accor-
ding to the medium. When the starting material
is too coarse for the generator, the generator can
clog up and hence become ineffective. In additi-
on, the sealing surfaces run dry, so that they are
damaged.
The generators are suitable for solids compo-
nents with the following grain sizes:

The dispersion tool must be brought into the
vessel off-centre, to avoid rotational turbulence
(vortexing).
For safety's sake, the vessel must always be well
secured.
When operating with the SI 400 safety limit
switch, the unit is only ready for service when it
has been locked in position at the planned wor-
king height and the switch contact operates the
safety limit switch.
The unit is started by pressing the ON button (A).
The unit is stopped by pressing the EMERGENCY
STOP button (B).
It can often be helpful to process a medium with
all three generators in sequence, starting with
generator G 65 G. Although it is easy to change
the generators, in such cases, it is worth buying
three shafts, that can then be changed with fe-
wer manipulations.
Pre-assembly of dispersion tools
Before the dispersion tools are connected to
the dispersion unit, the shaft and generator are
pre-assembled. The following tools (set of tools
included in the T 65 D ULTRA-TURRAX
package) are required to change the generator:
The slide ring seal must be correctly fi tted be-
fore pre-assembly of the shaft and generator.
