4. Installation

4.1 Wall Mounting

(with the included mounting set)
Please have the following on hand:
• Pencil;
• Drilling template;
• Philips head screwdriver;
• Power drill;
• 8 mm [0.3152 inch] drill bit, suitable for
penetrating the intended wall material.
Inspect the wall on which you intend
mounting the unit to ensure that it is capa-
ble of bearing the unit's weight!
1. Determine the optimum working height (Figure 1).
2. Align the drilling template and mark the drill holes
(Figure 2).
3. Drill the required holes (using the 8 mm [0.3152
inch] drill bit >>> to a depth of at least 55 mm
[2.167 inches]) + insert the dowels (Figure 3).
4. Screw the top screws into the dowels first
>>> allowing the screw heads to protrude 9-
10 mm [0.3546 - 0.394 inches] (Figure 4).
5. Mount the bottom mounting bracket (Figure 5).
6. Hang the unit on the wall (Figure 6).
7. Secure the unit with the knurled nut
>>> Securely tighten the knurled nut (Figure 7).
4.2 Benchtop Units
The Twister venturi can be operated as a benchtop
unit when a stand is employed.
1. Position the stand on a level surface (Figure 8).
2. Hang the unit in the stand (Figure 9).
3. Secure the unit with the knurled nut
>>> Securely tighten the knurled nut (Figure 10).
The stand is not part of the standard delivery and
must be ordered as an optional accessory (refer to
the „Accessories" section).

5. Commissioning /
Operation
Observe the pressure range information
in the technical specifications. A higher
inlet pressure will result in a lower vacuum
build-up.
For optimal operation as well as to prevent
damage, the compressed air should be cle-
an, dry, and oil-free.
Where the compressed air supply produces
an inlet pressure that is too high, or where
the compressed air is moist, contains oil, or
is contaminated, the Twister venturi should
only be operated with an upstream filter
pressure regulator (refer to the „Accessori-
es" section).

5.2 Commissioning
1. Connect the unit to the compressed air supply
(Figure 13a/b). A slight resistance which must be
overcome is felt when connecting the compressed
air hose to the unit (Figure 13a). Select the proper
coupling from the set provided and install it on the
other hose end to connect it to the compressed air
system (Figure 13b).
2. Connect the unit to the wall outlet (Figure 14).
3. Switch the unit on (Figure 15).
4. Adjust the desired speed
>>> 100 - 400 rpm (Figure 16).
5. Adjust the desired mixing time
>>> 0 - 5 min. (Figure 17).
Your Twister venturi is now operational.
5.3 Mixing Process
When mixing investment material, please
always observe the manufacturer's material
safety data sheets!
Wear appropriate protective gear as re-
quired!
