2. Safety
Please use this information to brief operators on how to use this appliance and about possible applications
and potential hazards during use.
This user information should be made available to the operator at all times.
2.1 Intended use
The Twister evolution / Twister evolution venturi vacuum mixer is designed solely for homogeneous, bubble-free mi-
xing of dental casting and modelling materials such as plasters, investments, and silicones.
2.2 Improper use
No accessories may be used on this appliance other than those supplied by Renfert.
The use of other components is not approved and carries the risk of serious injury.
2.3 Ambient conditions (according to DIN EN 61010-1)
7KHDSSOLDQFHVKRXOGRQO\EHRSHUDWHG
- indoors

Tests with various investment materials have shown that the best mixing results (smooth, homogeneous casting re-
sults) are obtained at the maximum vacuum setting. As a rule, this also applies to plasters. In individual instances,
independent tests have shown that – under extremely high vacuum – the partial pressure in the mixing bowl can
sink to a point where bubbles due to boiling can form in certain plasters. Then reduce the vacuum setting.
5.4 Mixing Process
Always read the safety data sheets supplied by the manufacturers when mixing investment materials!
