Information about explosion protection

Many of our competitors have been marking their products with the Ex symbol as a matter of prin-ciple for some time now.

At Krautzberger we do not do that.

We engineer and manufacture our products in line with currently applicable directives.

If the labelling on the product is required, it is affixed to the product as the result of the necessaryanalysis of ignition sources. If no labelling is affixed, the analysis of ignition sources and previousexperience with the assessment of the suitability of products for use in a potentially explosive areahave shown that the product described in this operating manual does not represent a potentialsource of ignition, with the exception of an electrostatic charge.

Taking into account the potential equalisation (provided by proper earth connection), the use in anarea at risk for explosions is permitted in accordance with the currently valid directives.

3 Safety and responsibility3.1 Responsibility of the ownerOwner

The owner is the person, who directly operates the machine for commercial or economical pur-poses or who allows a third-party to use/apply it and who is responsible for the legal product stew-ardship for the protection of the user, the personnel or third parties.

Owner responsibilities

The machine is used in an industrial environment. The owner of the machine is therefore subject tothe obligations as stipulated by the Occupational Health and Safety Act.

In addition to the safety information in this manual, the country-specific safety, accident preventionguidelines and environmental protection regulations, applicable at the site of implementation of themachine must be adhered to.

Furthermore, the owner is responsible for making sure that the machine is always in perfect tech-nical condition. Therefore, the following applies:

n The owner must ensure that the maintenance intervals described in this operating manual areadhered to.

n The owner must have all safety equipment checked regularly for functionality and complete-ness.

3.2 Intended useThe electric agitator is used to stir and mix fluids in closed depressurised or pressurised con-tainers.

The intended use also includes compliance with all of the specifications in this operating manual.

3.3 Specification for the operation of a complete machinen The operation without CE-marking is prohibited.n Prior to its use, the agitator must be assembled to form a complete machine.

3.4 Predictable misuseAny use beyond the intended use or any other use constitutes misuse.

n Always carry out installation, commissioning, and use in accordance with the steps describedin this operating manual.

n Ensure that the hose lines used meet requirements in relation to pressure as well as chemicaland mechanical loads.

n Always observe the applicable safety, accident prevention, occupational safety and environ-mental protection regulations for the area of use for the agitator.

n The chemical resistance of the materials which we use cannot always be assessed withauthority due to the large number of fluids, concentrations, temperatures and impurities used.For this reason, please test the suitability because we cannot offer any guarantees in thisregard.

n Only use the manufacturer's OEM parts.n Only operate the agitator in installed condition and in closed containers.n Only operate the agitator in a vertical position with agitator impellers facing down.n Only operate the agitator in compliance with the values specified in ( Ä Chapter 13 ‘Technical

data’ on page 47).



GB–11

n Adhere to the safety data sheets of the spray medium manufacturer.n The conformity of the product is voided in case of structural modifications to the agitator.

No claims of any kind can be asserted due to damage resulting from misuse!

3.5 General safety instructions

DANGER!

Risk of death due to electric shock!Touching conductive parts presents a direct risk of death. Damage to the insulation or to indi-vidual system components can be life-threatening.

Note:

– In the event of damage to the insulation, switch off the power supply and initiate repair.– Work on the electric system must only be carried out by qualified electricians.– Disconnect the system from the power supply and ensure that there is no residual

voltage present.– Prior to any maintenance, cleaning or repair work, switch off the power supply and

secure against restart.– Do not bypass fuses or take them out of commission. When changing fuses, make sure

you use the correct amperage.– Keep moisture away from live parts. Moisture can cause a short circuit in the system.

WARNING!

Risk of fatal injury from electrostatic charge!Electrostatic charges can cause shocks and sparks and thus lead to explosions.

– Ground the device or the machine properly.– Use conductive hose line (< 1 MW).– Place the device or the machine on an anti-static surface if possible.



WARNING!

Risk of death, risk of injury or property damage due to hazardous media!Potential consequences: The application of hazardous media can lead to death, severe inju-ries or property damage.

When handling hazardous substances, ensure that the current safety data sheets of the haz-ardous substance manufacturer are available. The necessary measures can be derived fromthe content of the safety data sheet. Since the hazardous potential of a material may be reas-sessed at any time due to new lessons learned, the safety data sheet must be checked regu-larly and replaced if necessary.

The system owner is responsible for the presence and the up-to-date status of the safety datasheet and the associated generation of the risk assessment of the effected workstations.

WARNING!

Health hazard due to the use of incorrect lubricants!Incorrect lubricants in the food and pharmaceutical industries can pose a health hazard.

– If used in the food and pharmaceutical industries for lubrication, only use food-grade oilsof viscosity class HL 32.

Outdoor operation and operation in exterior areas!

If in operation, use suitable measures to protect the device from environmental impacts in anexterior area through:

– Moisture– UV radiation– Frost, etc.

3.6 Residual risksDevices, machines or systems made by Krautzberger GmbH have been manufactured based onstate-of-the-art technology and in compliance with technical safety regulations.

Nonetheless, their use may pose a threat to the life or health of users or third parties, or harm thedevice, the machine, the system or other material assets.

n Mechanical hazards (crushing, shearing, cutting, jamming, burning, etc.) are possible at anytime during the installation, during operation as well as during maintenance work and serv-icing.



GB–13

3.7 Course of action in an emergency

In principle, the applicable national, regional and internal company regulations concerning thecourse of action in case of an emergency must be adhered to and if necessary respectivesafety measures must be taken on the system owner's side.



4 Transport, storage, and packaging4.1 Transportn The agitator is protected by cardboard packaging.n The cardboard packaging can be reused for storage.

4.2 StorageStore packages under the following conditions:

n Do not store outside.n Store in a dry and dust-free environment.n Keep away from any aggressive media.n Protect from UV radiation.n Avoid mechanical shocks.n Storage temperature: 15 to 40 °C.n Relative atmospheric humidity: max. 60%.

4.3 PackagingThe agitator is packaged in accordance with the anticipated transport conditions and the packagingneeds to protect it against transport damage, corrosion, and other damage.
