solely for homogeneous, bubble-free mixing of dental
casting and modelling materials such as plasters,
investments as well as silicones.
2.1 Ambient Conditions
(in accordance with DIN EN 61010)
The unit may only be operated:
• Indoors;
• Up to an altitude of 2,000 m above sea level;
• At an ambient temperature range between
5 - 40ºC [41 - 104ºF] *);
• At a maximum relative humidity of 80% at 31°C
[87.8°F], dropping in a linear manner to 50% rela -
tive humidity at 40°C [104°F] *);
• With mains power where the voltage fluctuations
do not exceed 10% of the nominal value;
• Under over-voltage category II conditions;
• Under contamination level
2 conditions.
*) Between 5 – 30°C [41 – 86°F], the unit can be operated at
a relative humidity of up to 80%. At temperatures between
31 – 40°C [87.8 – 104°F], the humidity must decrease
proportionally in order to ensure operational readiness (e.g., at
35°C [95°F] = 65% humidity; at 40°C [104°F] = 50% humidity).
The unit may not be operated at temperatures above 40°C
[104°F].
