It is a complete system of tubes, fittings and tools, mostly used for heating applications, but also for e.g. cooling, compressed air and heat pump connections. With the growing importance of safety & security on one hand and lack of time on the building site on the other, making the VSH carbon steel press system available for sprinkler installations was an obvious choice. Therefore VSH has obtained the German VdS approval early 2008 and will soon obtain other relevant approvals as well. 3

2 2 Advantages of VSH Press Sprinkler Galvanized system In the building installation market the advantage of press systems over traditional solutions like black steel and threaded fittings have long been recognized. The same advantages apply for sprinkler installations, the most important ones we summarize below: Performance guaranteed Reliable Easy & Clean Safe Speed Apart from these advantages, the aesthetics of a VSH carbon steel installation (compared to e.g. black steel) are often a reason for architects & designers to prescribe our system for in-sight installations. 2.4 Safe Installation of the VSH Press Sprinkler Galvanized system does not require a heat source (as for welding) or other potentially dangerous tools. Moreover, the light weight of the precision thin-wall steel tubes ensures improved labour conditions and as such a healthier way of working. 2.5 Speed Reduced labour time is probably the most important advantage of the VSH Press Sprinkler Galvanized system, not only resulting in reduced costs but also important in times when it is difficult to find sufficiently skilled people to work on the projects. Based on given advantages, we believe that the VSH Press Sprinkler Galvanized system will have the preference for sprinkler installations in particular for distribution systems. VSH Press Sprinkler Galvanized system, an impressive solution! 4 2.1 Performance guaranteed 5 With all fittings being manufactured in our state-of-the-art factory in The Netherlands, VSH can guarantee consistent quality and supply. High-tech manufacturing using laser welding technology ensures that all welded fittings are tested 100%. This leak test is entirely integrated and automated in the laser welding process. Furthermore all straight connectors with a threaded end, as well as most reducers, are made out of one piece. This means no risk of leakage and short build-in dimensions. Performance in flow is obvious, with the extremely smooth surface of tubes and fittings, flow rates are much better than those in traditional solutions. 2.2 Reliable In VSH Press Sprinkler Galvanized systems, the quality of the connections is mainly determined by the tool and not the operator, therefore reducing the risk of installation mistakes. All fittings are equipped with Leak Before Pressed (LBP) o-rings, to reduce this risk even further. This LBP function ensures that fittings that have not been pressed, will leak during the initial pressure test. The installer can immediately see which fitting he forgot to press and correct this. Once pressed, the system is guaranteed water and air tight. 2.3 Easy & clean The VSH Press Sprinkler Galvanized system is extremely user friendly: No need to thread the tubes No lubrication Easy tube insertion due to the special VSH design of fittings Short radius bends, compact installation This means that less skills are required for the installation and that installation can take place in a more pleasant environment.

3 3 Components 3.1 Preliminary remark These assembly and installation instructions apply to the VSH Press Sprinkler Galvanized system for the construction of fixed wet sprinkler systems only. The VSH Press Sprinkler Galvanized system consists of the following components: VSH Press Sprinkler Galvanized fittings VSH Press Sprinkler Galvanized tubes Press tools VdS recognition of the VSH Press Sprinkler Galvanized system was awarded in 2008. It applies to the dimensional range with a diameter DN20 to DN50 (22-54 mm) with an operating pressure of 16 bar for wet tube sprinkler systems. Here VSH press fittings made of zinc-plated unalloyed steel are used, including a C-steel tube produced specifically for the VSH Press Sprinkler Galvanized system whose inner and outer surface is galvanized. 3.3.1 VSH Press Sprinkler Galvanized tube The VSH Press Sprinkler Galvanized tubes for wet sprinkler systems are thin-walled precision steel tubes corresponding to EN10305-3 (previously DIN 2394/NEN 1982). The tubes are made from cold rolled steel that is galvanized using the Sendzimir process. During this process zinc is brought onto the metal strip, running through a zinc bath, covering both sides simultaneously. The tube is protected both on the inside and outside with a zinc layer. The thickness of this layer is at least 12μm. With the Sendzimir process good adhesion of the zinc layer and corrosion resistance are achieved. Fire behaviour VSH Press Sprinkler Galvanized tubes are classified as non-combustible tubes of building material class A, DIN 4102, part 1. 3.3.2 VSH Press tools The prescribed available press tools consist of a press machine and the accompanying press jaws or press slings. The press machine can be battery or mains operated. For each tube diameter the corresponding press jaws or press slings should be used in order to ensure a completely tight connection. 6 7 3.2 The press fitting connection The connection between the tube and fitting is created by pressure using a press tool. The fitting sleeve is deformed and adapts to the surface of the tube, which is then pressed in turn against the sealing rings on the surface of the fitting. This ensures the sealing effect and prevents the tube from slipping out. See illustrations 1 & 2. All VSH Press fittings are produced with the "M" pressing contour. Pressing of the VSH Press Sprinkler Galvanized system is only permitted with press machines and press jaws or slings (M profile) made by Novopress. Other machines are not permitted due to the VdS system test symbol on the VSH Press Sprinkler Galvanized system. In this section an overview is provided of all press machines, press jaws and press slings made by Novopress which are approved. 3.3.2.1 Overview of the VdS-approved press tools Novopress Comfort line Basic line ECO ACO EFP AFP before pressing after pressing 201 201 201 201 Illustration 1 Illustration 2 301 3.3 VSH Press Sprinkler Galvanized fittings The VSH Press Sprinkler Galvanized fittings are manufactured from unalloyed steel with the material no. 1.0034 [steel 34-2]. They are protected against external corrosion by means of a zinc layer (8-15 µm) applied by electroplating. VSH Press Sprinkler Galvanized fittings are produced in the dimensions DN20 to DN50 (22-54 mm). The fittings are equipped with an LBP sealing ring (EPDM) as standard. 3.3.2.2 Comfort line Novopress ECO 301 DN20-50 (22-54 mm) Power supply Power Piston force Piston stroke Dimensions L x B x H Weight 220-240 V / 50 Hz 560 W 45 kn 45 mm 420 x 85 x 110 mm 5.0 kg 1 LBP: Leak Before Pressed

Regular maintenance and lubrication of the press jaws, slings and tools is required. Please see the manufacturer s instructions for use and maintenance.

4 4 Applications 4.1 Fixed sprinkler systems Fixed sprinkler systems are permanently installed fire extinguishing and fire protection systems which independently detect and report a fire and automatically start the extinguishing process. The installation of the VSH Press Sprinkler Galvanized system in sprinkler systems is carried out in accordance with appropriate guidelines (e.g. (VdS)-CEA 4001).

The fastener distances apply if there are no other working installations such as other tubes located above the sprinkler tube 10 When the VSH Press Sprinkler Galvanized system is used it should also be ensured that no loads can fall on to the tube network under normal conditions or in the case of a fire; for example ventilation ducts and cable trays must not be installed above the sprinkler tubes. If the sprinkler tube has to cross other structural elements such as ventilation ducts or cable trays for planning or structural reasons, the sprinkler tube must be secured in front of and behind these potential loads by additional components (see illustration 3). In addition, ventilation ducts should be attached by further approved fasteners in the crossover area (see illustration 4). The values listed in table 4 apply to the fastener distances.

In dimensions within the range DN20 to DN50 (22-54 mm) with the black EPDM sealing ring VSH Press Sprinkler Galvanized is only approved for use with wet tube sprinkler systems. 11 Illustration 3: Arrangement of the retaining fixtures in the case of crossovers (cable tray) Illustration 4: Arrangement of the retaining fixtures of crossovers (ventilation duct)

5 4.2 VdS certification The VSH Press Sprinkler Galvanized system has been tested and certified in accordance with the VdS guidelines for use in fixed wet tube sprinkler systems. These guidelines refer to the VSH Press Sprinkler Galvanized system with a working pressure of 16 bar in the dimensions DN20 to DN50 (22-54 mm), such as those included in the VSH Press Sprinkler Galvanized System product range (see section 7). Additionally, the approval can be found on a double-sided galvanized steel tube specifically developed for the sprinkler system, with a zinc layer on both the inside and the outside of the tube. VdS certification is a system approval, meaning that the approval is valid if the following components are combined: VSH Press Sprinkler Galvanized fitting VSH Press Sprinkler Galvanized tube Press tool According to the VdS certification, the VSH Press Sprinkler Galvanized system may only be used in fixed sprinkler systems. Use in other extinguishing systems and dry sprinkler systems is not permitted. 12 13 The VdS-approved system may only be used for branch and distribution systems and not for risers. 4.3 Corrosion 4.3.1 Internal corrosion The VSH Press Sprinkler Galvanized tube is made of unalloyed steel and has a cathodic corrosion protection both on the inside and outside. The VSH Sprinkler Galavanized tube is produced out of zinc plated (Sendzimir process) material. The minimum thickness of the protection layer is 12 µm both on the inside and outside. After welding the tube is zinc plated 100%. The zinc layer is the cathodic protection and is functioning as a sacrificial anode to counteract corrosion. Entrance of oxygen from outside is alsmost neglegible. In order to avoid frost damage, calcification or corrosion, appropriate chemical additives should be put in the water (for example glycol). Please enquire about the chemical additives which should be used. 5 Technical data 5.1 VSH Press Sprinkler Galvanized fittings VSH Press Sprinkler Galvanized fitting Laser marking Press Galvanized VdS Dimension Table 6: Identification markings for press fittings Packaging Label Typ C...

Nevertheless, it is possible that in some cases systems are exposed to the undesirable penetration of moisture or steam for prolonged periods, which may lead to problems. However, the operator and plumber are responsible for carrying out appropriate measures. Illustration 5

6 Thanks to the special grooves in the O-ring (illustration 5) the Leak Before Pressed O- ring (LBP) ensures optimum control of the system during the prescribed pressure test according to CEA 4001, no. 17.1.1. Unpressed connections will leak water and are therefore easy to detect (illustration 6). During the pressing procedure the O-ring deforms and the connection between the tube and fitting is sealed, ensuring a watertight connection. Illustration 6 6 Processing instructions 6.1 Transport and storage During the transport and storage of VSH Press Sprinkler Galvanized tubes and press fittings it is important to avoid damage and soiling. 6.2 Cutting the tube to size After the measurements have been taken the VSH Press Sprinkler Galvanized tube for sprinklers can be cut to size with a tube cutter or fine-toothed handsaw (illustration 7). 6.3 Deburring the tube The tube ends should be carefully deburred on the inside and outside after cutting to length in order to prevent damage to the sealing ring when the tube is inserted into the press fitting (illustration 8). Deburring can be carried out both on the inside and outside either with a suitable hand deburrer or with an electric tube deburrer. Burrs sticking to the tube must definitely be removed. 14 15 6.4 Calibration It must be ensured at all times that the tube ends are radial and even rounded.

The tube, press fitting and O-ring should be examined for foreign matter (e.g. dirt, burrs), which should be removed if necessary. 6.6 Fitting depth marking In order to guarantee secure and professional pressing, the required insertion depth (see table 10) has to be marked on the tube or the press fitting before assembly (illustration 9). Reliable pressing with the corresponding tensile strengths can only be achieved by proper installation. The pressing operation behind the crimp is of crucial importance for the tensile strength. After the pressing process the marking on the tube must still be visible! Illustration 9 Illustration 10

6 6.7 Assembly of tube and fittings Before the pressing operation the fitting or the tube is inserted as far as the insertion depth while being rotated slightly and pressed in an axial direction at the same time (illustration 10). The marking for the insertion depth must still be visible! In the case of fittings without a stop (e.g. sleeves) the tube must be inserted at least as far as the marked insertion depth. Rough and careless insertion of the tube into the press fitting may result in damage to the sealing ring and is therefore not permitted. The assembly of tube and fittings may be made more difficult due to the permitted tolerances in size. In this case the sealing ring can be treated before assembly with a lubricant, e.g. soapsuds or water. Under no circumstances may oils or grease be used as lubricants. For practical reasons and in order to optimise the installation time, it is standard procedure to establish a certain number of connections first before pressing the different tube connections one after the other. Marking the distance (A) is therefore necessary in order to ensure that the tube has not been pressed out of the fitting during the pressing procedure for the different connections. 16 17 Before the final pressing operation is carried out for the different tube connections, some of the minimum clearances must be checked (see table 10). a b d a c Illustration 11 Illustration 12 Illustration 13 b 6.7.1 Pressing Before starting the pressing process the press jaw must be checked for dirt, which must be removed if present. Furthermore, it must be ensured that the press machine is in good condition and that the instructions for operating the device, regular maintenance and the manufacturer's instructions have been followed. It must also be ensured that the correct press jaws and press slings for the fittings are used. In order to create a proper pressed connection, the groove of the press tool must enclose the press fitting o-ring bead. Once the pressing has started always complete the press cycle and under no circumstances interrupt the process. Insertion depth Table 10: Minimum distance between pressings Table 11 lists important minimum distances and the space requirement for an installation in order to guarantee correct processing.

For this, commercially available manual, hydraulic or electric bending tools with the corresponding bending segments are used. The suitability of the bending tool is defined by the manufacturer. VSH Press Sprinkler Galvanized tubes for sprinkler installations are cold pliable. C-steel tube Due to the danger of corrosion the tube must not be bent when it is warm. The minimum bending radius is as follows: Rmin = 2 x D 6.7.3 Threaded couplings The VSH Press Sprinkler Galvanized product range also comprises articles with internal and external thread for connection with other threaded parts of a tube network (for example sprinkler heads, valves, mountings). Internal and external threads are produced in accordance with DIN 2999/ISO 7/1. Teflon may be used as sealing material for the C-steel threads. For threaded connections we recommend that the pressed connections should not be subjected to a load. [*Slings]

6 6.8 General instructions for use 6.8.1 Flushing the network After completion of the installation work the entire sprinkler system has to be thoroughly rinsed through with filtered (drinking) water. Flushing of the system is necessary in order to guarantee that it is working correctly and to prevent contamination within the system. After the system has been rinsed through it has to be drained off. The sprinkler heads then have to be attached after the removal of all the materials required for flushing the network. 6.8.2 Filling and bleeding the tube network After flushing of the tube network has been carried out, it should be filled with filtered drinking water and completely bled. Local pressure drops Local pressure drop is, as mentioned in the introduction of this section, the resistance to flow that results from changes in the flow direction and cross-sectional area, flow splitting over several channels, etc. There are in general two possibilities to calculate these flow resistances: the direct analytical method and the method using equivalent lengths. DN 20-50 (Ø 22-54 mm) Method of equivalent length (m) 1,5 0,7 0,5 0,5 0,4 0,9 1,3 1,5 3,0 m 6.8.3 Pressure testing The tubes belonging to the sprinkler system must be subjected to a pressure test according to valid guidelines, for example (VdS) CEA 4001, no. 17.1.1. lasting at least two hours. During the 18 25 28 1,90 0,90 0,60 0,60 0,50 1,10 1,50 1,90 3,80 19 test a pressure (measured at the alarm valves) corresponding to 1.5 times the permitted positive operating pressure - but at least 15 bar - must be maintained. This pressure test is a check of both the strength and tightness of the system. 6.8.4 Flow loss Every fluid that flows through a tubing system experiences continuous and local flow resistances that are apparent from the pressure drop in the system. There is a difference between the continuous and the local pressure drop. The continuous pressure drop is mainly caused by the flow resistance in straight tube sections which in turn essentially results from the friction between the fluid and the tube wall. Local pressure drops, on the contrary, are those flow resistances that are caused by turbulence, for instance where there is a change of internal tube diameter, a tube branch, in an elbow, etc. Continuous pressure drop To calculate the total pressure drop resulting from the flow of fluids in a straight section of the tubing system, first determine the pressure drop over a unit of length and then multiply the total length with this value. This value can be determined analitically using the Hazen-Williams formula. 6,05 x 10 5 p = ------------------------- x Q 1,85 C 1,85 x d 4,87 DN mm ζ Direct analytical method 20 22 1,40 0,60 0,50 0,50 0,40 0,80 1,20 1,40 2,80 32 35 2,50 1,20 0,80 0,80 0,70 1,50 2,10 2,50 5,00 40 42 3,10 1,40 1,00 1,00 0,90 1,80 2,60 3,10 6,20 50 54 4,00 1,80 1,30 1,30 1,10 2,30 3,30 4,00 8,00 Table 12: Table of localized flow loss values of [ ζ ] and [equivalent meters] Direct analytical method The local pressure drop can be calculated with the following mathematical equation: v = flow velocity of the fluid [m/s] γ = specific gravity of the fluid [kg/m 3 ] ζ = local flow resistance coefficient PL= ζ x v 2 x γ/2 x 10-5 [bar] Table 12 gives the [ζ] values for every type of fitting. The given values are calculated for a water velocity of 0.7 m/s. We can assume that [ζ] is velocity independent for those velocities that occur in domestic installations or in other normal applications; this is supported by the fact that the change of [ζ] as a function of the Reynolds number in these velocity ranges is only minimal. Once the [ζ] value is known, one can read off directly the corresponding local pressure drop. p = pressure loss in the pipe [bar/meter] Q = flow through the pipe [l/min] d = mean internal diameter of the pipe [mm] C = constant for type and condition of the pipe C=140 for VSH Press Sprinkler Galvanized pipe Tables for other situations can be requested at VSH or downloaded from website www.vsh-fittings.com The pressure loss due to velocity may be ignored.

7 Equivalent length method This is a calculation method that solves the calculation problem as a function of a particular local resistance and gives the equivalent length of a straight piece of tube with the same diameter that would have the same pressure drop. In order to use this method of calculation all length-equivalent values for each fitting type in table 12 are to be added to the actual length of the supply network. The total calculation of the equivalent length is multiplied by continuous pressure drop [bar/m]. This will show the overall resistance in the circuit. This method is not as accurate as the direct method but has the advantage that the calculation can be carried out faster.
