Information for Operators

The following information is intended to assist you,
the operator, in safely working with the Duomix in
your laboratory.
Using these operating instructions as a
starting point, instruct all operators of the
unit with regard to the area of application,
the possible hazards during operation, and
the proper operation of the unit.
Please have these operating instructions readily
available for the operators.
A. Application Area

A.1 Proper Use

The Duomix is designed solely for the extrusion of
2-component precision impression materials.
The Duomix is capable of working with 5:1 cartridges
or tubular bags in reinforcing cartridges from various
manufacturers.
Always comply with all safety and
processing instructions provided by the
manufacturer!
Impression materials are to be processed in
accordance with the manufacturer's
instructions!
Dynamic mixing nozzles with hexagonal head drives
can be used for mixing.
Only the mixing nozzles specified by the
manufacturer may be employed.

Error
• Incorrect mixing nozzle installed.
• Mixing tip/ foil bag not compatible.
• Pressure discs are too worn or have
been damaged, causing the tubular
bag to be pinched between the pres-
sure disc and the cartridge.
• The material has partially hardened
in the cartridge.
• Material has hardened in the mixing
nozzle.
• The controller has detected an over-
load.
• Material has hardened in the cart-
ridge.
• Insufficient spindle lubrication.
Corrective action
• Use the mixing nozzle specified by the manufacturer.
• Contact the manufacturer of the mixing tip / foil bag.
• Replace the pressure discs (refer to Sec. 3.3).
• Replace the cartridge (refer to Sec. 2.2).
• Use a new mixing nozzle.
• Impression material is too cold, Refer to the
manufacturer's processing instructions.
• Use a new cartridge.
• Lubricate the spindles (special grease!)
A.2 Ambient conditions for
safe operation
Safe operation of the unit can only be ensured under
the following ambient conditions:
• Indoors;
• Up to an altitude of 2,000 m above sea level;
• At an ambient temperature range between
15 - 40ºC [59 - 104ºF] *);
• At a maximum relative humidity of 80% at 31ºC
[87.8ºF], dropping in a linear manner to 50%
relative humidity at 40ºC [104ºF] *);
• With mains power where the voltage fluctuations
do not exceed 10% of the nominal value;
• Under contamination level 2 conditions;
• Under over-voltage category II conditions.
*) Between 15 – 30°C [59 – 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].
A3. Ambient conditions for
storage and transport
Ensure the following ambient conditions during sto-
rage and transport:
• Ambient temperature -20 – +60ºC [-4 – +140ºF],
• Maximum relative humidity 80%
