6. Commissioning /
Operation
1. Connect the unit to the wall outlet (Figure 13).
2. Switch the unit on (Figure 14).
Your Twister evolution pro is now operational.

6.1 Mixing Process

When mixing investment material, please
always observe the manufacturer's material
safety data sheets (health-hazardous dust
emissions).
Do not fi ll the mixing bowl beyond the maxi-
mum fi ll mark. The maximum fi ll mark ap-
plies to powders and liquids in their unmixed
states.
Attempting to mix small quantities in large
bowls will result in inadequate mixing.
Tip:
Only mix the same type of material in a given
bowl. Residue form previous mixing processes
can have a negative infl uence (e.g., silicon fails to
harden, etc.).
We recommend a separate bowl for each type of
material (plaster, investment, silicon).
1. Select an appropriate size mixing bowl.
2. Using a spatula, lightly mix the materials together
(Figure 15) or use the premix function (refer to
Sec. 7.4).
3. Install the appropriate paddle (Figure 16).
Make sure the bowl rim (Figure 17a) and
cover rim (Figure 17b) are clean!
4. Select the desired program:
• Press the programming key, "P" (Figure 18). The
LED below the programming key goes on.
• Select the desired program by turning the control
knob (Figure 19).
5. Couple the mixing bowl to the unit (Figure 20). Do
not release the bowl until it stays in place by itself!
The motor should start automatically and run
briefl y when the bowl is inserted. The unit is
equipped with an automatic coupling aid that
locks the paddle to the motor shaft when the
bowl is inserted.
6. The vacuum pump starts automatically.
7. Once the minimum vacuum has been achieved
(the unit beeps), the mixing program begins auto-
matically.
8. The unit beeps once the mixing program has been
completed.
9. To remove the mixing bowl, press the control knob
(Figure 21). The bowl will be released in a few
seconds.
Hold the bowl!
6.2 Interrupting the Mixing
Process
The mixing process can be cancelled at any time
prior to its normal end.
1. Stop the mixing process:
>>> Press the control button once (Figure 21).
2. Remove the bowl:
>>> Press the control knob again (Figure 21). The
bowl will be released in a few seconds.
Hold the bowl!
6.3 Adjustment During the
Mixing Process
During the mixing process, all mixing parameters
can be displayed on display B by briefl y press-
ing the associated parameter key (E) (Figure 22)
(refer also to Sec. 7.2).
All mixing parameters can be also changed during
the mixing process.
After pressing the desired parameter key, the as-
sociated LED goes on. While the LED remains on,
you can change the selected parameter by turning
control knob F (refer also to Sec. 7.3).
Any changes made to the mixing parameters
during the mixing process will only apply to
the current cycle and cannot be permanently
saved. Refer to Chapter 7 for instructions on
how to change and save mixing parameters.
7. Programming
The Twister evolution pro allows mixing parameters
to be saved to 10 programmes (0 – 9).
Mixing parameters can be permanently saved under
a programme number, or they can simply be changed
and applied to the next mixing process.
When the unit is at rest, display C shows the currently
selected programme, while display B indicates the
mixing time (the LED under the "Mixing time" param-
eter key is on)

7.1 Programme Selection

1. Press programming key "P" (Figure 18). The LED
under the programming key goes on for approx.
6 seconds.
• While this LED is on a programme can be selec-
ted.
2. Select the desired programme (0 - 9) by turning
the control knob (Figure 19).
3. The selected programme is active once the LED
under programming key "P" goes out. This hap-
pens when:
• The control knob is not turned for a period of
longer than approx. 6 seconds;
• One of the parameter keys, E, is pressed;
