3 3 1. Technology in generally The following references and information are purely recommendations. In principle current standards, guidelines and recognized rules of technology are to be considered by the processing plant. 1.1 Storage and transport With storage and transport, damages, contamination and in particular with stainless steel materials, the contact with iron and unalloyed steel must be avoided. Thus, it is recommended to cover, e.g. in the case of transport on a truck, the loading area with a foil if previously this truck transported pipes or construction units of unalloyed steel. 1.2 Outside corrosion protection Usually the corrosion resistance of SANHA system components (fittings and pipes) makes an outside corrosion protection dispensable. Ambient atmosphere and/or medium temperature can nevertheless make an outside, diffusion-close insulation necessary in order to hinder corrosion attacks from the outside. Special attention should be paid with aggressive content materials in the atmosphere and during a possible condensation on the outside pipe surface. 1.3 Insulation of pipes Pipe insulation depends, in particular regarding the isolation strength, on the respective application. The isolation strengths are to be selected by the processing plant depending on operational area and according to the legal defaults and regulations. The processing references of the insulating material manufacturers are to be observed. 1.4 Sealants and sealing aids Sealants, like e.g. gaskets, may not deliver chloride ions to the water or lead to local enrichments of lead chloride ions. With the Centellen seals used in SANHA components, this requirement are fulfilled. For thread connections, the use of a permanent elastic thread sealant is recommended. When using hemp, a chloride-free sealing aid is to be used. The use of thread tape (Teflon band) is not recommended. 1.5 Leak test The leak test with water according to EN 806 and/or the national standards and regulations may be executed only if the drinking water unit is taken into operation times at the latest 48 hours hereafter. During the compression test with water, the test pressure must correspond to 1.5-fold of the system operation pressure. For hygienic reasons, the leak test of drinking water pipelines should be carried out as dry testing by means of inert gases (e.g. nitrogen) or oil-free compressed air. The examination is accomplished in two sections. The leak test (preliminary test) is carried out with a pressure of 110 mbar over a period of time of 30 minutes with maximum content of the drinking water pipe system of 100 litres. For every 100 litres, the test period is extended by 10 minutes. The strength test (main examination) is executed with a maximum pipe dimension up to DN 50 with a test pressure of 3 bars and with a maximum pipe dimension larger than DN 50 with 1 bar, over a period of 10 minutes. For the pressure measurement, a calibrated manometer with a display accuracy of 1 mbar must be used. Appropriate inspection reports can requested from the technical SANHA hotline as well as downloaded on the Internet under The leak test must be executed at one time, at which the connection points are still accessible and not yet covered.

4 4 1. Technology in generally 1.6 Flushing the drinking water installation In principle all drinking water pipelines, independent of the kind of material used, are to be flushed thoroughly with filtered drinking water. Rinsing must be carried out as early as possible and following the pressure test. Thereby the following goals are to be achieved: Ensuring the drinking water quality (hygiene) Cleaning the tubing interior surfaces Avoidance of malfunctions at armatures and apparatuses These demands are fulfilled by two flushing methods: Flushing with air-water mixture Flushing with water An additional disinfection of the pipes is in principle not necessary according to EN 806 and/or the national standards and regulations do not require it. Nevertheless, if in individual cases a disinfection of the pipes be necessary for special reasons, then the details concerning certified disinfectants and disinfection methods should be coordinated with our technical customer advisory service in advance. Appropriate flushing protocols can be requested from the technical SANHA hotline as well as downloaded on the Electrical trace heating Electrical trace heating can be used for the SANHA building services systems if the pipe s inner wall temperature does not exceed 60 C in the long term. A brief rise of the temperature up to 70 C for the purpose of the thermal disinfection is permissible. With the use of electrical trace heating, closed pipe sections ranges, which do not have their own safety devices, may not be heated in order to avoid an unintentional increase in pressure within these ranges. It is essential that EN 806 and EN 1717 are observed. 1.8 Electrical protective measures For all electrically conducting system components, a potential equalization is to be carried out. The metallic SANHA installation systems (,, SANHA Therm) execute a continuous electrically conductive fitting and thus must be included in the potential equalization. For the implementation of these electrical protective measures, the installer of the electrical system is responsible.

15 2.6. Linear extension of the pipes Heated pipes extend themselves differently depending upon material and temperature difference. If the pipes are prevented from this thermally caused length variation, then the mechanical stresses predominating in the pipe material can exceed the permissible values, whereby damage (usually in the form of fatigue fractures) can be caused. In order to avoid this, sufficient extension leave must be given to the pipes. 15 Thermal expansion of various pipe materials Dl = a l 0 DT Pipe material Heat extension coefficient a[ 10-6 K -1 ] (20 to 100 C) Dl [mm] for l 0 = 10 m DT = 50 K Stainless steel 16,5 8,3 Copper 16,6 8,3 Steel pipe galvanised 12,0 6,0 Compound pipes 23,0 11,0 For the compensation of aforementioned length variations, often the elasticity of the pipeline can be used. It is necessary to establish within the range of pipe detours the correct arrangement of the securing clips to ensure sufficiently flexible pipe limbs. The basic principle reads that between two fixed points there should always be sufficient stretching possibility If natural pipe conduit does not offer sufficient compensation for the possible thermal expansion, this must be ensured through the installation of special construction units such as e.g. metal bellow compensators. If sufficient space is available, also a U-pipe-compensator can be used. With concealed piping, the unhindered thermal expansion is to be ensured by the fact that the pipes are covered with flexible chloride-free material of sufficient thickness. In particular with ceiling ducts, insofar no specific fixed point has been set, are to be padded sufficiently Spacing between pipe mountings Pipes are to be connected by means of commercial clips direct with the building and may not be fastened to other pipes. In order to fulfil the noise control requirements, clips with rubber lining are to be used. The clip spacing is shown in the following chart. Mounting spaces for metallic pipes Pipe outside diameter in mm ,1 88,9 108 Mounting space in m 1,20 1,20 1,50 1,80 1,80 2,40 2,40 2,70 3,00 3,00 3,00 3,00 Mounting space for Multilayer pipes Pipe outside diameter in mm Mounting space in m 1,00 1,00 1,50 2,00 2,50 3,00 3,50 4,00 In each case, clips may be attached on the pipe, not on the fitting. In order not to set unintended fixed points, a certain distance from detours is to be observed. Since apparatus and device connections function as fixed points, a certain distance is to be kept also by these.

16 Permissible bending radii Stainless steel, copper and C-steel pipes can be bent with suitable bending tools within certain limits cold. A bending radius, measured in the neutral fibre of the sheet, is to be observed for SANHA system pipes of stainless steel and unalloyed steel of at least r = 3.5 x d and for copper of at least r = 3 x d. It is to be made certain that after bending, a sufficiently long cylindrical pipe for the subsequent treatment is present. With larger than above specified dimensions, the manufacturer of the bending implement is responsible for a perfect bending result. SANHA system pipes can be bent up to the dimension of 28 mm cold. MultiFit -Flex system pipes can be bent by hand, with bending springs and with bending devices. Depending on the assigned bending procedure, the minimum bending radii with bending assistance may not fall below r = 2 x d and without bending assistance r = 5 x d. The pipe may not be curved on a length of at least 1 x d (outside diameter) after the grouting. Warm bending of stainless steel and C-steel pipes is not permitted. Copper tubes may not be warm-bent (inclusive) with drinking water installations up to the dimension of 28 mm Space requirement For installation required spacing of the pipe from the wall, corner and wall masonry is to be inferred from the following sketches and charts. Minimum spacing between two press points (see following chart) Minimum spacing to wall (see following chart) Pipe outside diameter in mm Nominal size DN Insertion depth in mm e Minimum spacing in mm A min L min B min C min , , , Minimum spacing between two press points as well as between wall and press point

17 17 3. Pipe connections 3.1. Recommended pressing tools General requirements SANHA is the only manufacturer of press systems who independently gives guarantee for the tightness of the press connection, regardless of the manufacturer of the pressing tools if the press machines and press jaws fulfil the following requirements: The pressing tools must be maintained according to the respective manufacturer guidelines. Compact press machines (up to including 28 mm) must exhibit a minimum pressing force of 18 kn and a pin diameter of 10 mm. Conventional and electronic pressing machines (up to including 108 mm) must exhibit a minimum pressing force of 30 kn and a pin diameter of 14 mm. With metallic fittings up to including 54 mm in diameter, pressing jaws and slings for press connections of the type M-MM must exhibit the original profiles SA, M or V. With metallic fittings with more than 54 mm in diameter, pressing jaws and slings for press connections of the type M-MM must exhibit the original profiles SA, M. For plastic compound fittings, pressing jaws and slings must exhibit the original TH-outline. The SANHA installation instructions for the finished system must be observed SANHA pressing tools Each SANHA pressing machine is provided with a round maintenance plaque. From the marking of this plaque can be inferred, when the machine must be sent to the Company Novopress or one of the companies Novopress authorised for maintenance. With regular maintenance (once a year) the guaranty increases to three years. Press machines of other system suppliers and/or machine manufacturers are to be maintained according to their stipulation, however at least once a year The pressing jaws are stressed by strong, oscillating forces. This can lead in extreme cases to material fatigue, at least however to a clear wear - in particular that of the pin. In order to exclude dangerous accidents, here are two feasible ways presented: Regular maintenance of the pressing jaws Here, all worn parts or deformed parts are to be exchanged, so that after this maintenance, the user has a pressing jaw which is almost as new. Limitation of the life span The other possibility of preventing accidents consists of attaching at the pressing jaw a break section in such a way that the pressing jaw is destroyed after a certain life span and thus is no longer usable. With SANHA pressing jaws and slings, both procedures will be used.

18 18 With pressing jaws and slings for the electronic pressing machine (catalogue number 6920, 6932, 6933 and/or intermediate jaws catalogue number 6931,1, 6931,2, 6931,3) and with SANHA pressing jaws and slings for service plus for conventional (compatible) pressing machines (catalogue numbers 6940, 6932 and/or intermediate jaws catalogue number 6930) the procedure of regular maintenance is used. These Pressing jaws are as already stipulated with SANHA Novopress pressing machines provided with an inspection label, on which the next inspection date is given. With regular annual maintenance, the guaranty for these pressing jaws and/or pressing slings is increased up to five years. SANHA pressing jaw standard (catalogue number 6958) should be checked at the latest once a year after purchase or after 10,000 pressing jobs (depending on, which enters first) by an authorised inspection station. This examination is to be repeated at the latest one a year and/or 10,000 pressing jobs after the respective inspection. Basically it is to be differentiated between conventional and electronically controlled pressing. With conventional pressing we are talking about a pressing job, which always takes place in the same way with same energy expenditure. In contrast to it, with the electronic controlled pressing by means of chip integrated into the pressing jaw which communicates with electronics of the pressing machine the pressing job is force-optimised and thus gentle to the material, tool, fitting and pipe. In particular with the smaller dimensions, this leads to a substantial increase of the life span of the pressing jaw and the pressing machine fit -Press installation tools For a professional installation of the 3fit -Press system, apart from the pressing tools specified before, a pipe cutter (SANHA article no ) or suitable pipe cutting equipment as well as dimension-dependent calibrating tools with UVUD function ( un-pressed leaky ) (e.g. SANHA article no , article no ) are necessarily for cutting to length and deburring/calibrating the MultiFit -Flex system pipes. Calibrating tools with UVUD function may not be used for 3fit -Push fitting!
