Safety
General Guidelines
• The owner must comply with these operating instructions and the authorized use of this piece of equipment. Should problems
arise that cannot be solved using these operating instructions, please contact Dixon Sanitary. We will be happy to provide
further assistance.
• If any modication work is performed on the product by the owner, Dixon shall no longer be considered the manufacturer of the
device. In such cases, all components must be subjected to a new certication process for any applicable certications that the
equipment holds. Unless agreed to in writing by Dixon, liability, warranties, and guarantees shall immediately be deemed null and
void as soon as you:
- Perform modications/conversion work on the product.
- Use the product for unauthorized purposes.
- Remove or disable safety elements.
- Process products whose material, form, and size do not correspond exactly to the description provided.
- Make alterations to the original state of the device.
• The operating instructions are regarded as part of the valve.
• The operating instructions shall be valid for the entirety of the device's lifespan.
• The operating and maintenance personnel must always be able to access the operating instructions.
• The safety instructions provided in the operating instructions must be observed.
• The operating instructions must be maintained and updated as necessary.
• The operating instructions must be passed on to any subsequent owners or operators of the device.
The following signs may be used in this manual. To avoid serious injury and/or possible damage to equipment, pay attention to
these messages. Hazards or unsafe practices could result in severe personal injury or death.
Use only replacement parts and devices recommended by the manufacturer to maintain the integrity of the equipment. Make sure
the parts are properly matched to the series, model, serial number, and revision level of the equipment.
Safety labels are placed on equipment where appropriate. Do not remove any labeling from any piece of equipment. Replace any
label that is missing.
DO NOT modify any Dixon® product. Non-factory modications could create hazardous conditions and void all warranties. DO NOT
attempt to use a Dixon product in any application that exceeds the product rating.
Indicates a hazardous situation that, if not avoided, will result in death or serious injury.

Safety
Owner Must Ensure...
• The product is used only as authorized.
• The product is used only when it is in fault-free, fully functional condition and the safety equipment is regularly checked to ensure
that it is fully functional.
• The product is operated, maintained, and repaired only by personnel with the appropriate qualications and authorization.
• Checks are made before the product is put into operation to ensure that only the authorized person is in the work area and no one
is in danger of being injured if the product is in operation.
• The product is checked for visual damage prior to commissioning to ensure that it is operated only when free of faults.
• Any defects are reported immediately to the appropriate supervisor.
• All safety and warning notices attached to the equipment are legible, and none are removed.
• The operating instructions are always kept close to the product operation site, in a legible and complete state.
• Personnel are regularly instructed on all occupational safety and environmental protection issues and are familiar with and
observe the operating instructions, especially the safety instructions contained herein.
• Personnel are trained and supervised to ensure that they follow safety measures, including the obligatory use of personal
protective equipment.
• The product is only connected to pipelines that are depressurized at the time of connection.
• There is no tensile or compressive stress acting on the product connections.
• There is no residual risk at any point where pressure could occur. Pressure can cause sudden failure in or damage to the lines
and connections.
• Warning notices in the documentation for supplier modules are observed and integrated into the risk assessments
in the workplace.

Care of Stainless Steel
The stainless steel components in Dixon®Sanitary equipment are machined, welded, and assembled by skilled craftsmen using
manufacturing methods that preserve the corrosion-resistant quality of the stainless steel. Retention of corrosion-resistant qualities
under processing conditions requires regular attention to the precautions listed below. Examples of corrosion that can result from
improper care are included below.
• Regularly check all electrical devices connected to the equipment for stray currents caused by improper grounding,
damaged insulation, or other defects. Corrosion: Pitting often occurs when stray currents encounter moist
stainless steel.
• Never leave rubber mats, ttings, wrenches, or other tools in contact with stainless steel. Corrosion: pitting or galvanic action.
Objects retard complete drying, preventing air from reforming the protective oxide lm. Galvanic corrosion occurs when two
dissimilar metals touch when wet.
• Immediately rinse equipment after use with warm water until the rinse water is clear. Clean the equipment (COP or CIP) as soon
as possible after rinsing. Corrosion: discoloration, deposits, and pitting. Product deposits often cause pitting beneath
the particles.
• Use only recommended cleaning compounds. Purchase chemicals from reputable and responsible chemical manufacturers
familiar with stainless steel processing equipment. Ensure they continuously check the effects of their products on
stainless steel.
• Use cleaning chemicals exactly as specied by the manufacturer. Do not use excessive concentrations, temperatures, or
exposure times. Corrosion: pitting, discoloration, or stress cracks. Permanent damage often occurs from excessive chemical
concentrations, temperatures, or exposure times.
• For manual cleaning, use only soft non-metallic brushes, sponges, or pads. Brush with the grain on polished surfaces to avoid
scratching the surface. Corrosion: pitting, scratches. Metal brushes or sponges will scratch the surface and promote corrosion over
a period of time. Metal particles allowed to remain on a stainless steel surface will cause pitting.
• Use chemical bactericides exactly as prescribed by the chemical manufacturer in concurrence with the local health authority.
Use the lowest permissible concentration, temperature, and exposure time possible. Flush immediately after bacterial treatment.
In no case should the solution be in contact with stainless steel for more than 20 minutes. Corrosion: protective lm destroyed.
Chlorine and other halogen bactericides can destroy the protective lm. A few degrees increase in temperature greatly increases
chemical activity and accelerates corrosion.
• Regularly inspect the joints in pipelines. Be sure all connections are tight tting without binding. Corrosion: crevice corrosion.
Small crevices caused by improperly seated gaskets will promote crevice corrosion. Stainless steel under stress will develop
stress cracking, especially in the presence of bactericides containing chlorine.
• Regularly inspect equipment for surface corrosion (i.e. pitting deposits, stress cracks, etc.). If deposit or color corrosion is
detected, remove it immediately using mild scouring powder and detergents. Rinse thoroughly and allow to air dry. Review
production and cleaning procedures to determine the cause. NOTE: If corrosion is not removed, the protective lm cannot be
restored, and corrosion will continue at an accelerated rate.
