1. Notes for the user
1 . 1 Intended use
GUTH mixers are designed and constructed solely for commercial and industrial use. They are
used for mixing, stirring, distribution and homogenising purposes.
The mixer must be attached to the container by using appropriate fittings. The attachment and the
container must be designed to withstand the forces that occur. Stirring solid materials and materials
with a relatively high viscosity is considered as predictable and improper use of the mixer.
Do not use the mixer in a hazardous area!
1 . 2 Notes on the guarantee
All obligations arising in connection with the guarantee are contained in the General Terms and
Conditions of Guth Ventiltechnik GmbH.
1 . 3 Safety instructions
The mixer may only be fitted and commissioned by qualified personnel.
Based on the definition laid down in EN 60204-1. Qualified personnel:
A person who, on the basis of his or her specialist training, has acquired knowledge and experience
as well as knowledge of the relevant standards and can evaluate the work entrusted to him or her
and any possible hazards.
NOTICE
Please read this handbook carefully before you begin with the assembly of, commissioning of or
any other work connected with this mixer.
• The mixer may only be used for approved purposes.
• The GUTH company shall accept no liability for damage and operational malfunctions resulting
from failure to observe these instructions.
• Technical modifications resulting in deviations from the illustrations and information contained
in these instructions may be made without prior notice being given.
• The mixer may only be fitted and commissioned in accordance with these operating instruc-
tions.
• The manufacturing process did not take account of safety precautions in respect of external
fire.
• The mixer may only be converted or modified after consulting with the GUTH company.
• The original replacement parts supplied by the GUTH company serve the purpose of ensuring
safety. Should other parts be used, the GUTH company shall accept no responsibility whatso-
ever for any damage that may result.
• The mixer may only be disassembled when it is not connected to a voltage supply or under
pressure.
• Prior to repair and maintenance operations, the product line must be de-pressurised and free
of fluid product. Product residues and cleaning agents must be removed as well.
• Mixers that come into contact with hazardous media must be decontaminated.
• Never touch the mixer when hot liquids are being processed or the sterilization process is
underway.
• Never touch the rotating parts of the mixer.
• If hot or cold parts represent hazards, then these parts must be shielded against the possibility
of persons coming into contact with them by the plant operator.
• The mixer must always be rendered pressure-less during all assembly and disassembly work.

1. Notes for the user 4
The mixer may only be fitted and operated by a trained person.
Based on the definition laid down in EN 60204-1.Trained person:
A person who is taught by a qualified employee about the tasks entrusted to him/her and the pos-
sible hazards caused as a result of improper conduct and if necessary trained and who has learnt
about the necessary protective equipment and protective measures.
1 . 4 Safety instructions
Failure to observe the specified hazard warnings may pose a risk to persons as well as the envi-
ronment, mixer and plant. Specifically, failure to observe the warnings may cause the following haz-
ards to arise:
• the failure of important functions of the mixer and the plant.
• the failure of prescribed methods for maintenance and repairs.
• hazards to persons caused by electrical, mechanical or chemical agents.
• environmental hazards on account of leakage of hazardous substances.
1 . 5 Safety tests
Safety tests "carried out by the manufacturer in the factory".
Safety tests according to DIN EN 60 204-1
- Continuous connection of the protective conductor system.
- Insulation resistance tests.
- Voltage tests.
- Protection from residual voltages.
- Functional tests.
- The functions of the electrical equipment, especially those which relate to safety and protective
measures.
ATTENTION
The mixer may only be operated when it is in perfect working order. In addition
to the documentation, instructions on the following also apply:
- Internal plant working and safety instructions
- National regulations in the country of implementation
- Generally accepted safety regulations
- Accident prevention regulations
DANGER
• The electrical connecting cable must be laid in a position where nobody can trip over it!
• Only assemble or disassemble the mixer when the mains plug has been pulled out.
• Please ensure that the container fittings are connected correctly to the filled container when
using the mixer.
• Close the container fitting before disassembling the mixer.
• Pay attention to ensure that you collect or divert the product liquid that is produced when
employing or removing the mixer.
• Avoid knocking over the electrical connecting cable.
• Please ensure that the electrical connecting cable does not cause an injury.
• Pay attention to the clockwise field of rotation when configuring the three phase current of the
motor. Otherwise two phases of the connecting cable must be exchanged by qualified electri-
cians.

2 . 3 . 2 Types of propeller
2 . 3 . 3 Accessories
Pivioting sash propeller
The pivoting sash propeller (standard) is primarilyused to
ensure installation on closed and filled containers. It is
introduced into the container fitting in a folded state and
unfolds when the device is started.
Triple vane propeller
Due to its robustness, the triple-vane propeller enhances
the process of dissolving sugar, fining agents and similar
substances in open containers or tubs.
Fig. 3 Propeller-types
Mixing head
The mixing head is a triple-vane propeller with an addi-
tional protective ring. This ensures that damage caused
from stirring in open containers is avoided.
Gassing device
A special flange housing enables direct gassing with sul-
phur dioxide, carbon dioxide and similar elements when
the agitator shaft is rotating. This enables the gases
being fed to the liquid to be mixed thoroughly immedi-
ately upon influx.
Fig. 4 Accessories
Tapping pipe
The tapping pipe with union nut enables the GUTH mix-
ers to be installed on the flap gates and similar fittings
without the agitator shaft being damaged upon being
introduced and removed.
