Cleaning & Maintenance; Spare Parts - Renfert Twister Mode D'emploi

The vacuum pump starts automatically.
5. Wait until sufficient vacuum has been
created >>> the indicator must be out
of the red range on the scale (Fig.
21a). To start mixing, press the
control button (Fig. 21b). The device
will beep when mixing is completed.
6. To remove the mixing bowl, press the
control button (Fig. 21b). Caution:
Hold the bowl securely! The bowl will
be released in a few seconds.
6.2 Interrupting the Mixing
Process
1. To stop the motor, press the control
button once (Fig. 21b).
2. To shut off the vacuum, press the con-
trol button again (Fig. 21b).
Caution: Hold the bowl securely!
6.3 Adjustments During the
Mixing Process
• You can change the mixing time and
speed while the device is operating
(Fig. 15/16).
• The mixing time you set before starting
the process is saved.
• If you change the mixing time during the
process, the new time will not be saved.
Tip:
Only mix the same type of material
in a given bowl. Residue form pre-
vious mixing processes can have a
negative influence (e.g., silicon fails to
harden, etc.).
We recommend a separate bowl for
each type of material (plaster, invest-
ment, silicon).
7. Cleaning / Maintenance
The Twister vacuum mixer is practically
maintenance-free.
7.1 Intake Filter
The vacuum built-up is only
warranted with cleaned suction
filter.
Clean the suction filter regularly according
to soiling, at least monthly.
When filters are too heavy soiled, they
have to be changed (see spare part list).
1. Switch the device off.
2. Unscrew the intake filter (Fig. 22).
3. Clean the filter in an ultrasound bath
(we recommend GO-2011 plaster
solvent,
Art. No. 2011-0000).
4. Reinstall the intake filter (Fig. 22).
Never operate the device without
the intake filter!
7.2 Seal Surfaces
The following seal surfaces must always
be kept clean in order to ensure correct
vacuum built up and the secure retenti-
on of the mixing bowl during the mixing
process:
a) Seal between the device and the
paddle (Fig. 23a);
b) Seal between the paddle and the bowl
(Fig. 23b).
Tip:
You should regularly coat the rubber
seals with Vaseline. This will signifi-
cantly increase their service life and
optimize to unit's function
