The following instructions must be observed to ensure safe, proper, and fault-free use of the product. DL Kunststofftechnik GmbH accepts no liability for damage, defects, or consequential damage resulting from improper use, incorrect or unprofessional installation, failure to observe this user information, or use outside the intended conditions. The customer's statutory warranty rights remain unaffected by this.<\/p>

1. General<\/strong><\/p>

All work must be carried out in compliance with the applicable occupational health and safety, safety, and accident prevention regulations, as well as the recognized rules of technology. All persons involved must wear the necessary personal protective equipment.
Pipes and tanks for wastewater, sewage, urea, or fuels must be permanently and clearly marked\u2014either visually or in writing\u2014with the words \u201cNot for drinking\u201d to prevent misuse. Since even with correct labeling, confusion cannot be completely ruled out, it is recommended that suitable safety mechanisms (e.g., child-proof valves) be installed at all taps.<\/p>

2. Composition<\/strong><\/p>

The product is made of high-density polyethylene (PE-HD), which has properties such as food safety, excellent resistance to diesel, seawater, acids, and alkalis, temperature resistance up to 80\u00b0C (diesel and urea up to 50\u00b0C), odor impermeability, low density (approx. 0.96 g\/cm\u00b3), good UV and aging resistance, corrosion resistance, and excellent electrical insulation properties.<\/p>

3. Construction<\/strong><\/p>

Each product must have at least one separate vent at the highest point. This also applies if corresponding openings have not been provided by the manufacturer. Liter figures, volume specifications, or fill quantities specified, calculated, or expected by the customer are for guidance only and do not constitute a guaranteed property. The design, construction, and manufacture of the product are based exclusively on the drawing approved by the customer. DL Kunststofftechnik GmbH is entitled to make design adjustments, in particular to baffle plates. No separate consent from the customer is required for this. Unless expressly agreed otherwise, black weld seams are used on white tanks. Due to the design, threaded areas are always reinforced by approx. 8 mm from the inside. Baffle plates are not attached to the tank cap unless this is expressly and clearly specified in the drawing.<\/p>

4. Installation<\/strong><\/p>

Before installation or assembly, it is essential to check the product for damage, leaks, dimensional accuracy, and functionality (e.g., by performing a test fill). Any manufacturing residues must be completely removed before commissioning. Failure to do so may result in blockages, malfunctions, or consequential damage to the product and connected systems.
No sharp or pointed objects may be used during installation. Ensure that the product is permanently protected against mechanical stress, movement, and torsion when installed. Installation under tension or pressure can lead to material fatigue, cracking, deformation, or sudden failure of the product. Due to temperature-related expansion and contraction of the material, the tank bottom must rest fully and permanently on a stable base, even in multi-stage or sloped designs.
Straps, perforated tapes, or similar fasteners must not be attached directly to weld seams for fastening purposes. Fastening to weld seams can damage or detach them and cause the product to burst or lose its tightness during operation. All threads must be properly sealed with suitable sealants. Installation in the engine compartment is not permitted.
Overpressure tests may only be carried out with the prior written approval of DL Kunststofftechnik GmbH. Overpressure tests that have not been approved may lead to excessive stress and cause the product to deform or burst.
Lifting and transport may only be carried out by lifting the tank from underneath or using the designated lifting points or crane eyes. Improper lifting, especially using improvised lifting points such as straps or loops, can lead to damage, cracking, or complete failure of the product.<\/p>

5. Warnings<\/strong><\/p>

The products must always be handled with care. They must be stored frost-free and protected from direct sunlight. No objects may be placed on the products. The products must be protected from fire and must not be exposed to mechanical, thermal, or chemical overload. Ventilation openings must not be used as overflows under any circumstances. Only liquids expressly specified in the offer or on the invoice may be filled into the products. In the case of shower trays, shower bases, wet rooms, or similar applications, a non-slip mat must be placed on the product to minimize the risk of accidents.<\/p>

6. Instruction for use and operation<\/strong><\/p>

The products must be handled with care. The products must never be dropped, as this can cause unacceptable damage that impairs their tightness, stability, and safe functioning. If products have been dropped or mechanically damaged, it is essential to carry out a new function and tightness test before further use.<\/p>

Before each filling and before each operation, check that:
\u2013 the vent pipe is functional, clear, and unobstructed,
\u2013 all cleaning openings are properly closed,
\u2013 All connections are securely and tightly connected with the designated hoses\/pipes.<\/p>

Ventilation
The vent line is a safety-related component. It must only be used for venting and must not be closed, kinked, narrowed, or used for any other purpose. A blocked or misused vent line can lead to unacceptable overpressure in the product.<\/p>

Filling and monitoring
The filling process must be monitored continuously. During filling, always check for leaks. Overfilling must be avoided at all costs.<\/p>

The product must not be filled completely. The maximum fill level of 95% must not be exceeded, as otherwise there will not be sufficient expansion space for the liquid to expand. Overfilling can lead to overpressure and failure or bursting of the product.<\/p>

Operating conditions \u2013 Risk of overpressure
The products must only be operated without pressure. Any form of overpressure\u2014e.g., due to overfilling, blocked or incorrectly used vent lines, or thermal expansion of the liquid\u2014is not permitted. Deviating from the specifications for pressureless operation can lead to serious damage, leaks, or the product bursting. There is a risk of significant personal injury, environmental damage, and property damage.<\/p>

Filling with hazardous liquids
When filling with hazardous or water-polluting liquids, a suitable drip tray must be placed under the product to safely collect any spilled liquids.<\/p>

7. Maintenance<\/strong><\/p>

The product must be checked for leaks at least once a year and cleaned if necessary. As part of maintenance, all connecting parts must also be cleaned and checked to ensure that they are securely fastened and in good working order.<\/p>

8. Information for the disposal<\/strong><\/p>

High-density polyethylene (HDPE) is a recyclable material. At the end of its useful life, the product can be disposed of properly at appropriate recycling or recovery facilities.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
