3 Installation requirements Manifold location Manifolds in manifold cabinets for tap water must be installed at a lower level than the outlets they serve. If this is not possible, a seal must be established between the conduit and the media pipe at the outlet, e.g. in the case of a kitchen connection. See Working procedure, section 8. Stud wall installation For installation to a stud wall, the minimum stud-frame thickness required is 95 mm for UNI cabinets, 120 mm for UNI 550 L and 145 mm for UNI 550 XL. If the cabinet is installed in a wet room, the cabinet must not be placed with the opening in wet zone 1. See image below from the Swedish industry regulations on Säker vatteninstallation (Safe water installation) for a definition of wet zone 1. 1,0 m våtzon 1 1,0 m Stud wall installation. Wallboard shall be cut edge to edge towards the manifold cabinet. Installation close to wall When installing near a stud wall, a distance of at least 35 mm is required from the outside of the cabinet to the adjoining wall in order to provide space for the LK Frame/hatch UNI INB. Working procedure 1 - Knockout If the feed is coming from the right or left side, see the arrows in the diagram below in order to select the right knock-out hole depending on whether the coupling pipes are to be connected from below or above. Knock out the knock-out hole using a hammer. Wet zone 1 Installation in a fire cell separation wall with LK Fire Hatch UNI When the cabinet is to be installed in a fire cell separation wall, the front edge of the cabinet must be positioned min. 70 mm from the outside of the finished wall. Installation height when installed on a stud wall To be able to install and create space for the drainage pipe, the cabinet must be installed at a height of at least 250 mm from the underside of the cabinet base to the finished floor. Installation height when installing on the surface of a wall During installation externally on an inner wall, the cabinet should be placed 250 (± 25) mm above the completed floor in order to provide space for the base. Coupling pipes from below and above. Cold water feed to the cabinet should come in to the left side and feed the lower manifold, and hot water is to be installed on the right side, feeding the upper manifold. For heating systems, the supply pipe is laid on the left side in the cabinet and supplies the lower manifold, and the return pipe is drawn on the right side and supplies the upper manifold. 3 (11)

4 2 - Prepare pipe inlets Prepare a LK Pipe Inlet for feeding pipes and coupling pipes by adapting/cutting inlets to the correct dimensions. LK Pipe Inlet 25 conduit, which is precut and adapted to 25 mm conduit, is available as an alternative. Pipe inlets are ordered separately. If the seal for the pipe dimension is damaged when cutting, then it must be replaced with a new seal. 1 Sealing Cutting of LK Pipe Inlet UNI.

5 3 - Assemble the pipe inlets and sealing plugs Mount the pipe inlets and the LK Sealing Plug before the cabinet is to be installed in its final location. Pay particular attention during the installation of pipe inlets and sealing plugs so the cabinet base is sealed. Plug the holes in the base that are not being used with the LK Sealing Plug. Mount these so that the LK Logo can be seen inside the cabinet. Mount pipe inlets and sealing plugs 4a - Mount the cabinet to the wall Fix the manifold cabinet in the building structure. For wood stud constructions, use the screws and sealing plates supplied. The cabinet can also be fixed using the LK Leg Stand. See under Installation aids. Position the cabinet correctly in terms of depth so there is space for any pipe insulation. The cabinet should never be installed further out than edge to edge with the stud-frame, so that the Frame/hatch INB can be installed. If LK Fire Hatch UNI is to be installed, the cabinet is to be installed at least 70 mm from the front edge of the cabinet to the outside of the finished wall. If the cabinet is placed on an outer wall, it should be installed on the warm side of the construction, inside the airtight foil. Attaching a cabinet to a stud wall 4b - Mounting a surface-mounted cabinet Secure the manifold cabinet to the building structure using an appropriate screw and the sealing washer supplied. Note that there must be no pipe lead-throughs in floors with sealing layers in bathrooms or shower rooms, except for drains and floor drains. 4c - Installing the cabinet to the ceiling Secure the manifold cabinet to the building structure in an appropriate manner, e.g. by securing suspended support M8 to the back of the cabinet. Only a layer of plaster or a ceiling panel may be applied between the cabinet and the frame. This is so that any water leaking out can escape quickly through the drainage holes in the hatch. 5 - Brackets The bracket is adapted for LK Manifold UNI 3/4 and pipe dimension mm. If LK Manifold UNI 1 is to be used, a rubber inlay must be removed. Bracket adapted for LK Manifold UNI 3/4 and pipe dimension mm. Bracket adapted for LK Manifold UNI 1. 5 (11)

6 6 - Bracket location Manifold bracket UNI-cabinet low is used for the upper manifold when coupling pipes are laid downwards, or for the lower manifold if coupling pipes are laid upwards. 8 - Pipe inlets/conduit umbrella Pipe with conduit is then installed up through the pipe inlet and cut/deburred. Manifold bracket UNI-cabinet low. Manifold bracket UNI-cabinet high is used for the lower manifold when coupling pipes are laid downwards, or for the lower manifold if coupling pipes are laid upwards. Manifold bracket UNI-cabinet high. Fit the manifold brackets low 2 pcs. and high 2 pcs. to the cabinet's rails. If more brackets are needed, these can be ordered as spare parts. Extra bracket bags are also available for UNI L and UNI XL. 7 - Mount the manifold To install the manifold in the brackets, use the self-tapping screw supplied (T25), which attaches the rubber-coated clip to the bracket. When the manifold is in place, all screws can be tightened. When the manifold is fitted, lock the brackets through tightening the wing nut against the rail. Installing a manifold Assembly of LK Conduit umbrella The LK Conduit umbrella can be installed if the outlet's conduit termination is lower than the one in the manifold cabinet. The LK Conduit umbrella is to be installed on the media pipe and pressed down towards the conduit. It can also be installed to coupling pipes for heating systems. 9 - Pressure and tightness check Pressure and a tightness check must be carried out according to "Assembly instructions for LK Universal Pipe PE-X & PAL" or in accordance with the Industry regulations Säker Vatteninstallation (safe water installation). Pressure and tightness check should be carried out before the wall covering is to be installed Tightness check of the cabinet base Connect the conduit to the bellow sleeve towards the cabinet s drainage opening. Bind the conduit so its opening is slightly above the base of the cabinet, or alternatively, use the accessory LK Bottom Plug in a drainage elbow or manifold cabinet. Pour water up to the edge of the cabinet base and wait about 10 minutes. Then check that the cabinet base is sealed. Look at the underside of the cabinet base to be sure there is no trace of water. After completing the tightness check, the cabinet is emptied of water and any residual water is dried up. Tightness testing must always carried out on the cabinet base before the wall covering is to be installed. 6 (11)

7 Then connect the drainage elbow to the conduit. Note that the pipe should rest in the drainage elbow, at a depth of about 40 mm. Then secure the drainage elbow in a suitable position against a wall stud or floor joist. Use the two installation screws supplied in any attachment holes. Tightness check of the cabinet base 11 - Installation of cabinet drainage Drainage outlets from cabinets with tap water installation must always open out into an area with a floor drain or watertight floor. Drainage outlets from cabinets with installations for heating systems may open out from the wall surface beneath the cabinet. Bear in mind that it must be possible to rapidly detect a potential leakage. 11a - Drainage elbow directly joined to the cabinet's outlet drainage The drainage is from the wall surface under the cabinet. Ensure that the white rubber seal is correctly mounted in the drainage elbow. Connect the drainage elbow directly to the cabinet's outlet drainage when all pipe inlets and sealing plugs have been mounted. For cabinets mounted externally on the wall, the drainage elbow opens out into the pre-drilled hole in the base. In the case of a pipe lead-through in a wall, the dimensions between the pipe and the adjacent wall or the sealing layer of the floor must be no less than 60 mm. Ensure that the conduit is installed with a slope towards the outlet and the conduit is secured. Drainage elbow connected by means of a conduit. 11c - Coupling of drainage pipes It is possible to connect drainage pipes from two cabinets. The illustration below shows side-byside installation, but drainage pipes can also be coupled at different cabinets. Use LK Drainage Kit 25 duo. Drainage elbow connected directly to the cabinet s outlet opening 11b - Drainage elbow connected via a conduit Connect the conduit to the bellow sleeve towards the cabinet s drainage opening. The bellow sleeve must not be deformed in a way that impedes any water leakage. Ensure that the white rubber seal is correctly mounted in the drainage elbow. Drainage elbow connected via LK Drainage Kit 25 duo. In the case of a pipe lead-through in a wall, the dimensions between the pipe and the sealing layer of the adjacent wall or floor must be no less than 60 mm. Ensure that the conduit is installed with a slope towards the outlet and the conduit is secured. 7 (11)

8 12 - Installation of outlet plate Install a wall panel with a hole for the drainage elbow s outlet pipe. Hole diameter approx. 26 mm. Connect any sealing layer as per the instructions of the supplier of the sealing layer. The LK Pipe Membrane can be obtained from LK Systems, but the sealing contractor should carry out the installation and be responsible for the sealing layer in line with the Swedish industry regulations from Byggkeramikrådet (The Council on Construction Ceramics) (BBV), GVK (Wet room inspection in the flooring industry) (Säkra Våtrum) and Måleribranschens våtrumskontroll (Wet room inspection in the painting industry) (MVK). Upon completing installation of the wall covering, the length of the drainage elbow must be cut down using the LK Pipe Mill DB. Alternatively, the drainage elbow can be cut to a suitable length using a hacksaw blade or knife, for example. Ensure that the surface layer is not damaged, leave 1-2 mm of the outlet pipe outside the wall surface. Install the LK Outlet Plate in the outlet pipe. If necessary, the inside of the outlet pipe can be lubricated with soapy water or similar. A more exclusive finish is available as an accessory with the LK Outlet Plate Chrome. In the case of roof mounting, splash protection must NOT be installed in the cabinet as drainage must take place through drainage holes in hatch Installation of frame/hatch There are four types of frame/hatch depending on whether the cabinet is built into or installed externally on an inner wall, in a ceiling or a fire cell separation wall. On delivery the hatch is fitted with a screwdriver lock, though an LK Key Lock is also available as an accessory (not for LK Fire Hatch UNI) Installation of frame/hatch UNI INB When the cabinet is fitted into a wall, use an LK Frame/hatch UNI INB, which has a flared frame to cover the holes around the cabinet. The frame covers an area of 15 mm beyond the edge of the cabinet. Fit LK Frame/hatch with the screws supplied. If the cabinet is installed as far into the wall that the screws provided do not suffice, these can be replaced with longer M5 screws (not in the LK standard range) LK Frame/hatch UNI INB Assembly of the LK Outlet Plate 13 - Installation of splash protection Install the splash protection supplied. Take care to ensure that the guard is pushed out to the side so the entire cabinet width is covered by the guard. Should be fitted during the construction period in order to prevent dirt and dust getting into the cabinet. The splash protection is what makes the cabinet safe from water damage, and it must always be mounted. 14b - Installation of frame/hatch UNI UTV When the cabinet is installed externally on a wall, use LK Frame/hatch UNI UTV which ends edge to edge with the cabinet s outsides. Plate and screws for LK Frame/hatch UNI UTV 8 (11)

9 Install the frame using the screws and mounting plate provided. See picture above. Mount the four white cover plugs on the ends of the cabinet intended hole. The lower part of the base is then pulled out to meet the floor. When the correct height is reached, the installation is done using screws on the front of the base. Then adapt the length of the drainage elbow to the outside of the base and install the outlet plate. LK Frame/hatch UNI UTV 14c - Installation of frame/hatch UNI TAK This product is only available for manifold cabinets UNI 350 and 550. When the cabinet is built into the ceiling, LK Frame/hatch UNI TAK is used which has a precipitating frame in order to cover the hole around the cabinet. The frame covers an area of 15 mm beyond the edge of the cabinet. The following is applicable to tap water installation: as the leakage indication takes place through the holes in the hatch, the cabinet must be positioned in a space with a floor drain or watertight floor. Only a layer of plaster or a ceiling panel may be applied between the cabinet and the frame. Fit LK Frame/hatch with the screws supplied. Fit the red plastic plug supplied in the drainage hole on the UNI cabinet (installed from inside the cabinet). LK Base installation Outlet plate mounted on base With ceiling mounting, the splash protection shall NOT be fitted in the cabinet as drainage shall take place through drainage hole in the hatch. 14d - Fitting a Fire hatch UNI When LK Fire Hatch is to be installed, take care with the positioning of the cabinet on a wall. Mount LK Fire Hatch UNI as indicated in the enclosed instructions for the product Installation of the base When installing LK Manifold Cabinet UNI externally, install LK Base by first securing the upper part of the base in the designated slots. Also ensure that the drainage elbow opens out into the 9 (11)

10 Installation aids Installation is done with the LK Cabinet Stand The back of the cabinet is fitted with four anchor points (M8 nuts) which can be used to mount the cabinet before the concrete slab is cast. LK Cabinet Stand, which is installed as shown below, is available as an aid. Mounting using the LK Leg Stand The LK Leg Stand simplifies cabinet assembly on prefabricated concrete joists. Manufactured from galvanized steel plate. Supplied in pairs with 4 self-tapping screws to fix to the manifold cabinet. The feet have 6 mm holes for fixation to the concrete floor structure. The legs are fixated using a bolt or metal nail plug (not supplied). In cases where the manifold cabinet is not adequately secured by the leg stand, then the cabinet should also be secured to the wall LK Cabinet Stand fitted along with LK Fixing plate Pipein-Pipe 25. LK Legs Replacement of pipes Fit lock plate on the conduit just above LK Pipe Inlet 25 in connection with any pipe replacement. LK Lock plate is ordered separately. Close-up of attachment to cabinet. Insert the four M8 bolts supplied in the back of the cabinet. Screw the pipe clamps on to the protruding bolts. Thread in the round bars and slip on the conduit parts supplied with the stand. The conduit prevents the stand from getting stuck, and as a consequence the stand is reversible. Push the round bars through the insulation and down into the sand until the installation feels steady. Raise the cabinet up to a suitable height and tighten the clamps. Tape the conduits to the stand legs to prevent the conduits from rising during casting. LK PE-X Universal pipe X16 can only be replaced starting from the angle wall bracket.
