1.1 Designated application

Flow Components Capital Equipment Engineered Processing Units

GUTH mixers ar

e designed and built solely for commercial and industrial use. They are used to mix, stir, disperse and homogenize. The mixer is mounted to the tank with fittings. The fittings and tank must be capable of withstanding the forces that occur.

Possible applications {XE "Possible applications"}:

- Stirring of liquids to prevent sedimentation of pulp and other solids, e.g. stirring of wine yeast for biological

acid decomposition.

- Production of uniform liquid mixtures even where various specific weights are involved.

- Clarification and homogenization when blending.

- Mixing of liquids with solid or gaseous products, e.g. to disperse clearing agents, sulphurous acid or carbonic acid.

- Emulsification of sterile preparations and homogenized distillates.

- Acceleration of reactions and dissolution processes, e.g. influencing of fermentation by dissolving sugar and

sugar solutions.

- Intensification of the efficacy of hot and cold influencing processes, e.g. uniform interspersion of liquids in

cooling processes.

- Activation of low-fermentation yeasts.

3.3 Built-in safety systems {XE "Safety systems"}

- The mixer is equipped with a one or thr

ee-phase, three or fivewire supply system with current-carrying N and

separate earth conductor (with yellow/green insulation).

This operating manual is an integral part of the mixer and must be kept readily at hand for the operators at all times. The safety instructions in it must be followed. Also pay attention to the protective motor switch built into the motor as safety system; see separate operating manual.

It is strictly forbidden to render any of the safety devices inoperative.

3.4 Safety precautions{XE "Safety precautions"} (to be carried out by the customer)

The customer must

- instruct his operating and maintenance personnel in the use of the mixer and its safety devices and

- ensure that the safety precautions are being adhered to. This operating manual is an integral part of the

mixer and must be kept readily at hand for the operators at all times.

The work described in this operating manual is explained in such a way that

- the chapters Transport, Operation and Installation can be

understood by a trained worker and

- the chapters Maintenance and Troubleshooting by a qualified technician.

Work described in the chapters Maintenance and Troubleshooting may only be carried out by qualified technicians.

Definitions based on EN 60204-1.

Trained worker {XE "Trained worker"}

- A person familiarized with and, if applicable, trained in his particular duties by a qualified technician and instructed

in the potential dangers in the event of improper conduct and in the necessary safety devices and safety precautions.

Qualified technician{XE "Qualified technician"}

- A person who, on account of his technical training, know-how, experience and knowledge of relevant standards, is

able to assess the work assigned to him and identify potential dangers.
