7.6 Special Function:
Automatic Parameter Display at
Programme Selection
With the automatic parameter display function acti-
vated:
• The LEDs under the keys of those parameters for
which a value not equal to zero has been defi ned
go on for approx. 2 seconds when a programme is
selected.
• The parameter values are each displayed for ap-
prox. 1 second in the following sequence:
Premix >> Pre-vacuum >> Speed >> Mixing time
>> Interval >> Post-vacuum
At the same time, the LED under the associated pa-
rameter key goes on.
This sequence can be interrupted at any time by
pressing a parameter key or by attaching a mixing
bowl.
Automatic parameter display at programme selection
can be activated / deactivated by:
1. Switching the unit off;
2. Simultaneously pressing and holding down the
pre- and post-vacuum keys;
3. Switching the unit on (while continuing to press
the pre- and post-vacuum keys, Figure 25).
4. The status change is indicated by a short audible
signal.
8. Cleaning / Maintenance
The Twister evolution pro mixing unit is practically
maintenance-free.
Nonetheless, the inlet fi lter and the seals should be
cleaned regularly as part of a preventative mainte-
nance programme.
8.1 Cleaning the Inlet Filter
The vacuum built-up is only warranted with
cleaned suction fi lter.
Clean the suction fi lter regularly according to soiling,
at least monthly.
When fi lters are too heavy soiled, they have to be
changed (see spare part list).
1. Switch the device off.
2. Unscrew the intake fi lter (Fig. 27).
3. Clean the fi lter in an ultrasound bath
(we recommend GO-2011 plaster solvent,
Art. No. 2011-0000).
4. Reinstall the intake fi lter (Fig. 27).
Never operate the unit without the inlet fi lter!
8.2 Seal Surfaces
The following seal surfaces must always be kept
clean in order to ensure correct vacuum built up and
the secure retention of the mixing bowl during the
mixing process:
• Seal between the unit and the paddle
(Figure 28a);
• Seal between the paddle and the bowl
(Figure 28b).
8.3 Replacing the Unit and
Motor Fuse
1. Unplug the unit from the wall outlet (Figure 13).
2. Unscrew the fuse holder cover (Figure 29).
3. Remove the fuse and replace it (Figure 30). Refer
to the "Technical Specifi cations" for the proper
fuse ratings.
Never use fuses with a higher current rating!
4. Reinstall and close the fuse holder (Figure 29).
9. Spare Parts
Please refer to the enclosed spare parts list for the
order numbers of spare parts and consumables.
10. Warranty
Provided the unit is properly used, Renfert warrants
the Twister evolution pro for a period of 3 years .
Presentation of the original bill of sale is required for
all warranty claims.
Components subject to natural wear (e.g., paddles,
mixing bowls, and intake fi lters) are excluded from
this warranty. The warranty is voided in case of im-
proper use; failure to observe the operating, cleaning,
maintenance, and connection instructions; in case of
independent repairs or repairs by unauthorized per-
sonnel; if spare parts from other manufacturers are
employed, or; in case of unusual infl uences or infl u-
ences not in compliance with the utilization instruc-
tions. Warranty service shall not extend the original
warranty.

Tip:
You should occasionally coat the rubber seals on
the paddle with Vaseline. This will extend the seals’
service life and ensures optimum vacuum force.
