Primarily for use in enamelled boilers or hot water tanks with other types of passive protective coatings. Signal anodes replace consumed conventional sacrificial anodes primarily in hot water tanks with a capacity of 100 to 500 litres. Defective areas in enamel or other passive protective coatings are subject to corrosion; this causes a flow of current which is transformed into a protective current by the anode material. The anode material thus falls victim to electro-chemical corrosion. Since the protective function of the anode rod is not unlimited, consumed anodes have to be replaced. Universal, complete signal anode as per EN 12828, made of magnesium alloy. Version with screw fitting, signal unit and instruction label. The parts submerged in water are heat-resistant up to operating temperatures of 100 C and comply with the German Food Act. When the anode material is used up, water penetrates the test space and causes a red discolouration of the signal unit to indicate that the anode is used up. In the case of conventional anodes, the boiler has to be opened for anode inspection.

10 Filters Water technology equipment Water filter WAF 04 with pressure reducer, backwashable With integrated pressure reducer Inlet pressure compensation for constant outlet pressure Rotatable cover to indicate the next backwashing date Transparent filter cup shows degree of pollution of the filter Innovative backwashing system fast and thorough cleaning of the filter, low water consumption Description For the protection of drinking water installations against corrosion as per DIN 188. The pressure reducer reduces the inlet pressure to an even, system-specific pressure in order to protect the installation and to ensure economical water consumption. Water filters help to keep pollutants such as rust particles and sand grains from reaching the domestic water installation and thus protect valves, machines, flow heaters, etc. from malfunctions caused by pollution. Ideal for modernisation of domestic water installations where an existing filter needs to be replaced. DVGW-tested water filter, compact plastic version with backwashable fine filter, integrated pressure reducer and pressure gauge for the outlet pressure. The fine filter consists of an upper part and a combined lower part. In the operating state "Filtration", the small upper filter is closed so that the water can only flow through the main filter from the outside to the inside. When the ball valve for "Backwashing" is opened, the filter is pressed down until the water supply to the outside of the main filter is interrupted. At the same time, the water flow through the upper filter is opened. The water required for cleaning the filter flows through the upper sieve, the rotating impeller and the main filter from the inside to the outside. This ensures effective cleaning of the filter across the entire surface of the sieve at full inlet pressure. When the ball valve is closed again, the filter automatically resumes normal operation. The pressure reducer operates on the basis of a force comparison system, i.e. the force of a spring counteracts the force of a diaphragm. The input pressure neither acts in the opening nor in the closing direction. Therefore, pressure changes at the inlet pressure side do not affect the outlet pressure.

The water filter keeps pollutants such as rust particles or sand grains from reaching the domestic water installation, thus protecting valves, machines, boilers, etc. from malfunctions caused by dirt. With its straightforward design and unobtrusive colour, the domestic water system centre fits in perfectly with modern equipment rooms, basements and utility rooms. Compact, tightness-tested domestic water system centre as a complete solution for the distribution of drinking water in buildings. The base version of HWSC consists of a backflow preventer, filter combination with fine filter and pressure reducer, drain unit with connection possibility to the wastewater system, three supply outlets, safety valve and all function components. The individual components are DVGW-certified or comply with the DVGW regulations. The assembly is contained in a form-fit insulation for easy access and operation. The integrated transparent front door allows for checking the system pressure and the safety valves and provides easy access to start backwashing; it is not necessary to remove the upper part of the insulation. The memory pointer on the door lets you set the date for the next backwashing procedure. HWSC excels with a dramatic reduction of the installation time: a drilling template is shipped with the unit for precise positioning of the three holes. Hanger bolts allow for precise adjustment of the domestic water system centre to the wall and enable easy horizontal and vertical alignment. HWSC features a variable height adjustment from 65 to 115 mm to allow for precise adaptation to the individual distance of the water meter from the wall. The default connection setting is intended for left-side connection, but HWSC can be converted to right-side connection in a matter of minutes. The integrated filter combination features an innovative backwashing system with rotating impeller which ensures fast and thorough cleaning of the fine filter and low water consumption. The entire sieve surface of the filter insert is cleaned at high pressure. The pressure reducer reduces the inlet pressure to an even, system-specific pressure; part of the water flows directly and without pressure reduction to the high-pressure outlet for the garden line. If this is not required, it can be converted into an additional pressure-reduced supply outlet. The insulation can accommodate up to four supply outlets; any additional outlets must be mounted outside the insulation. Due to the modular design and the defined connections, it is easy to fit extensions with an automatic backwashing unit, a refill combination for filling heating systems or a water softening system.

15 Water technology equipment Rainwater harvesting Rainwater harvesting an ecological necessity 75 % of the surface of our planet is covered with water, but only 0.03 % of all this water is potable. Almost 1 billion people have no access to clean water in Europe, however, toilets are still flushed primarily with drinking water. But even in Europe the call to save water is growing. The effort and money invested in drinking water treatment are on the rise. The almost 2 million rainwater harvesting systems already installed in Germany are evidence of increasingly responsible use of this valuable resource. This figure grows by about 65,000 new systems every year. Approximately 20,000 new systems are installed in France, 8,000 in Great Britain, about 2,500 in Austria and just under 1,500 systems in Switzerland. A rainwater system reduces the annual consumption of drinking water by about half; it often pays for itself within a few years and contributes to sustainable environmental protection. 1 6 Rainwater system centre RWSC II Probe for minimum level 2 7 Level indication Calmed inlet Rainwater suction line Plastic manhole cover Ø 500 for steel tank with inner lining Rainwater filter with stainless steel sieve Rainwater inner lining Floating suction fitting Downpipe filter Rainus Rainwater harvesting in single family homes with the rainwater system centre RWSC II and AFRISO oil tank conversion kits for decommissioned fuel oil tanks. 286 Division I

16 Rainwater harvesting Water technology equipment Facts Drinking water is too valuable for watering gardens, flushing toilets, washing clothes Rainwater harvesting helps to save energy (treatment and transport) Even in dry summers, there is usually a sufficient supply of rainwater Lime-free rainwater is better for horticultural purposes and requires less detergents Rainwater tanks serve as retainers and protect the mains drainage system from overloads Climate change has an effect on precipitation: both the intensity of rainfall and the duration of dry periods are on the rise. For an increasing number of municipalities, rainwater harvesting is not just a meaningful, but an essential and necessary part of local and regional water management In some countries and regions, rainwater harvesting systems are subsidised Rainwater harvesting saves money and protects the environment The rainwater collected on the roof area is fed through a filter system to the rainwater storage tank. The rainwater storage tank is connected to a control system (such as the rainwater system centre RWSC II) via a PE pipe. If water is requested, it is provided via the pressure-controlled pump of the RWSC II to the service water system of the domestic installation. If the supply of rainwater is insufficient, the system automatically switches over to drinking water. Rainwater tanks can be installed in the basement or underground in the garden. New installations normally use plastic or concrete tanks. However, it is also possible to convert existing cisterns, cesspits or oil tanks. For such purposes, AFRISO supplies special, customised linings made of plastic film (Sikaplan ) as well as plastic manhole covers with all the required connections. The AFRISO rainwater product portfolio focuses on the measuring and control components as well as conversion kits for decommissioned oil tanks.

17 Water technology equipment Rainwater harvesting Rainwater system centre RWSC II Suitable as a fully automatic rainwater harvesting system together with all standard rainwater storage tanks. For single-family homes, apartment buildings as well as small and medium-sized businesses For garden watering, washing machine and toilet Complies with DIN 188, DIN 18, EN 12056, EN 1717 and DVGW directives A A Page 14 Page 20 Description RWSC II is a reliable microprocessor-based control unit for the entire operation of rainwater harvesting systems in conjunction with all types of rainwater storage tanks (converted fuel oil tanks, plastic tanks, concrete cisterns). RWSC II is available in 2 versions: RWSC II 550 W is used for distances from the rainwater storage tank of up to 15 m. RWSC II 750 W is designed for distances from the rainwater storage tank between 15 m and 40 m. The compact RWSC is designed for continuous operation. Mains water backup to the mains water backup tank via a new, proven, reliable float valve. All other components such as the pump, pressure switch, control unit and three-way valve are modular and arranged on top of the mains water backup tank. This ensures easy accessibility for service and maintenance. RWSC II primarily uses rainwater from the rainwater storage tank. If the water level in the rainwater storage tank falls below a preset level, RWSC II switches over to mains water backup and uses mains water via the mains water backup tank. A short rain shower is often sufficient for RWSC II to switch back to rainwater mode. The integrated level indicator TopFlex provides precise information on the water level in the rainwater storage tank. With the digital tank contents indicator DIT, the level can also be displayed in "Litres", "m³", "%" or "Level mm" (option). If there is a danger of backflow, RWSC can be equipped with a backflow monitor (option). Drinking water backup can be monitor with Maximelder. RWSC II has been designed as per DIN 188 and DIN 18 and may be installed both above and below the backflow level.

18 Rainwater harvesting Water technology equipment Oil tank conversion kit I for rainwater usage in homes and gardens If heating oil storage tanks can no longer be used, for example due to corrosion, or if the heating system is converted to other types of fuel, it is a good idea to use the existing tank to collect rainwater and to integrate it into a rainwater harvesting system. For this purpose, the tank is cleaned by a specialised company and then fitted with an inner lining suitable for water. The old, standardised manhole cover (Ø 500 mm) is replaced with a plastic cover specially designed for rainwater harvesting; this considerably facilitates the conversion. The manhole cover contains all the required connections (filter, inlet, suction line and level probes). Description/ scope of delivery Conversion kit I contains: Rainwater system centre RWSC II 550 W Plastic manhole cover Ø 500 mm with 2 connections for pipes Ø 100 mm Cartridge filter PF for direct mounting to the manhole cover. Connections for inlet and outlet for pipes Ø 100 mm. Suitable for roof areas up to 210 m 2. Height offset inlet outlet 60 mm. 2 pipe couplers for the inlet and outlet pipes.

19 Water technology equipment Rainwater harvesting Oil tank conversion kits II + III for rainwater usage in gardens Oil tank conversion made easy. We supply a number of special rainwater components for quick and easy installation of rainwater harvesting systems. The tank cover is the most important component of the kit as it enables simple and clean piping through two openings. The pipe is routed from the downpipe to the tank top and connected to the filter system. Depending on the site conditions and the available space in the manhole, it is recommended to install a downpipe filter or a cartridge filter. Pipe couplers are used to connect the filter elements. The pipe to the sewage system must form a siphon using the drain pipe elbows. A self-priming jet pump with integrated pressure and dry run protection is ideally suited for water withdrawal.

20 Rainwater harvesting Water technology equipment Rainwater inner lining AR-SM with magnets Operation without vacuum type leak detector, no pressure, no current Easy and fast installation by means of powerful neodymium magnets Perfectly fitting, robust PVC lining Description For converting cylindrical steel DIN tanks such as decommissioned fuel oil tanks, diesel tanks or storage tanks into reliable, high-grade rainwater storage tanks. No pressure or flow required. The rainwater inner lining AR-SM with magnets is suitable for storing rainwater in cylindrical steel tanks (3,000 to 100,000 litres). The new rainwater inner lining AR-SM with magnets allows owners to convert a decommissioned steel tank into a rainwater storage tank with very little effort. Please note: In the case of coated steel tanks, verify that the attractive force of the magnets is sufficient. The rainwater inner lining AR-SM is a PVC lining with flat, round, extremely powerful neodymium magnets welded into lateral and top areas. The lining is reliably held at the inner wall by the magnets - no pressure or flow are required inside the tank. A tank can be conveniently converted into a rainwater storage tank: First, the tank is measured and then a precisely fitting lining is manufactured. The tank is prepared on the basis of a defined procedure (thorough cleaning of the tank, corrosion checks, etc.); depending on the condition of the tank, a fleece layer is placed on the tank floor for impact protection. Then the lining is fitted in the tank and inflated by means of a blower; if necessary, the final fit is achieved by means of a vacuum pump. When the PVC lining is inflated, the magnets click into place exactly where planned. The fit of the PVC lining is checked and then it is fastened in the manhole by means of a fastening ring. The tank is ready for storing rainwater immediately after the lining has been installed. Scope of delivery Rainwater inner lining AR-SM, made of plastic film Sikaplan WP black, film thickness 0.8 mm, for closed tanks, with all neodymium magnets welded into the film in the lateral and top areas, with film flange for the standard fastening ring. i Not only cylindrical DIN steel tanks, but certain steel tanks with different geometrical shapes can be converted into rainwater storage tanks. Please enquire. i Depending on the local conditions and on the tank, a fleece lining may be required in the bottom area of the tank as an impact protection. Different dome distances and special dimensions are manufactured at the same conditions. PG Part no.
