LK Shunt Cabinet VS2, Shunt Cabinet VS2 Prefab Design LK Shunt Cabinet VS2 The LK Shunt Cabinet VS2 is designed to be used when you wish to hide the LK Manifold RF and LK Manifold Shunt VS2. The cabinet has a sealed base with rubber pipe grommets. The base of the cabinet is fitted with a drainage opening which allows any water leakage to drain to a location that can be inspected in accordance with industry practices. The cabinet is made from 1 mm powder coated steel plate, RAL 9016. The cabinet can either be built into a wall or externally on a wall. The minimum stud-frame thickness when builtin is 95 mm. The cabinet is intended for right mounting, i.e. the primary shunt connection is from the right side via the cabinet base. The cabinet should be supplemented with a frame/hatch. There are two types of frame/hatch depending on whether the cabinet is built into or installed externally on an inner wall. LK Shunt Cabinet VS2 For external mounting, the cabinet should also be supplemented with a base to hide the pipes between the cabinet and floor. The LK Shunt Cabinet VS2 is supplied with pipe grommets, a bellow sleeve for drainage, 1.5 metres conduit for drainage, a drainage elbow with outlet plate, cable grommets for room control, spray guard and installation instructions. The back of the cabinet has four prefitted M8 nuts, which can be attached to the LK Cabinet Stand if you wish to install the cabinet before a concrete base is cast. LK Shunt Cabinet VS2 Prefab The upper side of the cabinet includes knock-out holes if needed for cable grommets for room control. LK Shunt Cabinet VS2 Prefab The LK Shunt Cabinet VS2 Prefab has an identical design to the above but with a pre-installed LK Manifold Shunt VS2 and the LK Manifold RF. The manifold is fitted with the LK Connection Couplings for PE-X/PAL pipes dim. 16. 1 (11)
LK Frame/hatch GV The LK Frame/hatch GV is intended for use with the LK Shunt Cabinet VS2. On delivery, the hatch is fitted with a screwdriver latch and a key latch is available as an accessory. The LK Shunt Cabinet VS2 should be supplemented with a frame/hatch. There are two types of frame/hatch. When the cabinet is built into a wall, the LK Frame/hatch UFH INB 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. When the cabinet is installed externally on a wall, the LK Frame/hatch UFH UTV is used, which fits edge to edge with the outsides of the cabinet. Assembly requirements Assembly in stud-frame For installation in a wall, a minimum stud-frame thickness of 95 mm is required. In cases where the cabinet is in a wet room, the cabinet must not be placed with its opening in wet zone 1. See image below from the Swedish industry rules on Säker vatteninstallation for a definition of wet zone 1. 1,0 m våtzon 1 1,0 m Wet zone 1 Installation height when installing in a stud-frame In order to assemble and leave space for the drainage pipe then the cabinet must be mounted at least 250 mm between the bottom of the cabinet base and the installed floor. The drainage pipe should be installed with a slope. LK Frame/hatch INB LK Base The LK Base is used when the Shunt Cabinet VS2 is installed externally on a wall. The LK Base hides the pipe installation between the cabinet and floor. The base can slide for heights from 220 to 280 mm. The base includes holes for installing cabinet drainage. If an alternative placement is used for cabinet drainage, the supplied cover plug can be used to hide the hole in the base. Installation height when installing ext. on a wall When installing externally on an inner wall the cabinet should be placed 250 (± 20) mm above the completed floor in order to provide space for the base. Assembly in stud-frame LK Base Assembly near a wall When installing near a wall in a stud-frame, at least 35 mm is required from the outside of the cabinet to adjoining walls to provide space for the LK Frame/hatch INB. 2 (11)

2 - Knock-out Remove the required number of knock-out holes for cables to room control. Install the cable grommets. If the feed pipes are to be connected from the side, the knock-out holes are removed from the side of the cabinet. The pipe grommets are then installed for the feed pipes. 4 - Install the cabinet Install the cabinet in the stud-frame externally on an existing wall taking into account the headings above regarding assembly height, wet zone 1 and installation near a 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. Pay attention to the depth of the cabinet's placement so there is also space for any pipe insulation. The cabinet should never be installed further out than edge to edge with the stud-frame, so the Frame/hatch GV INB can be installed. If the cabinet is placed on an outer wall, it should be installed on the warm side of the construction, inside the airtight foil. Remove the knock-out holes using a hammer and screwdriver 3 - Assemble the pipe grommets and sealing plugs Fit the adapted pipe grommets and the LK Sealing Plug before the cabinet is installed in its final location. Pay particular attention during the assembly of pipe grommets and sealing plugs so the cabinet base is sealed. LK Sealing Plugs are fitted so the LK Logo can be seen inside the cabinet. Securing the cabinet in a stud-frame 5 - Assemble the manifold & manifold shunt Assemble the bracket attachments on the cabinet's rail. Refer to picture below, Assembling the LK Manifold RF. LK Manifold RF is then mounted on the bracket attachments (when installing the LK Shunt Cabinet VS2 Prefab, the manifold is already mounted). Follow then the included instructions for installation of the manifold and pressure and tightness testing of its pipe connections. Install the shunt bracket at the assigned place in the cabinet. Then install the shunt group in the bracket. Push the manifold to the shunt group and tighten the unit. Assemble the pipe grommets and sealing plugs 5 (11)
Assembling the LK Manifold RF Leak testing of the cabinet base 8 - Install cabinet drainage Note that any leakage should be easy to quickly discover, which you should take into account when deciding where to have the outlet. Two different types of drainage elbows can be used, see below. Assembling the LK Manifold Shunt VS2 6 - Pipe grommets Pull the underfloor heating pipes through the pipe grommets. This is easier if the pipes have been lubricated with soapy water or similar. The pipes are then connected to the manifold in accordance with the instructions for the manifold. 7 - Leak testing of the cabinet base Connect the conduit with the bellow sleeve to the cabinet's drainage opening. Bind the conduit so its opening is slightly above the base of the cabinet, or alternatively, use the 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. When the cabinet seal has been checked, the cabinet drainage is assembled as below. A leak test is always carried out on the cabinet base before the wall covering is mounted. 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. For cabinets mounted externally on the wall, the drainage elbow runs through the pre-drilled hole in the base. The drainage elbow connected via a conduit. Connect the conduit with the bellow sleeve to the cabinet's drainage opening. Ensure that the white rubber seal is correctly mounted in the drainage elbow. Then connect the drainage elbow to the conduit. Note that the pipe should rest in the drainage elbow, about 40 mm deep. Fix the drainage elbow in a suitable location against the wall or floor beam. Use the two screws supplied in securing holes of your choice. Max. length for the conduit should not exceed 1.5 m and should have at most one 90º elbow. Ensure that the conduit is installed with a slope towards the outlet and the conduit is fixed. 6 (11)
Install the LK Outlet Plate in the outlet pipe. If necessary, the inside of the outlet pipe can be lubricated with soapy water or something similar. A more exclusive finish is available as an accessory with the LK Outlet Plate Chrome (Article no. 188 09 99). Drainage elbow directly joined to the cabinet's outlet drainage Assembly of the LK Outlet Plate 10 - Install Spray Guard Assemble the spray guard supplied. Be careful that the guard is pushed out to the side so the entire cabinet width is covered by the guard. The drainage elbow connected via a conduit 9 - Install outlet plate Install the wall board with holes for the drainage elbow's outlet pipe. Hole diameter approx. 26 mm. Connect any sealing layer in accordance with instructions from the supplier. The LK Pipe Membrane can be obtained from LK Systems (Article no. 481 43 82), but the sealing contractor should carry out the assembly and be responsible for the adhesiveness of the seal in line with the Swedish industry regulations from Byggkeramikrådet (BBV), GVK (Säkra Våtrum) and Måleribranschens våtrumskontroll (MVK). Upon completing installation of the wall covering, cut the length of the drainage elbow using the LK Pipe Mill DB, or cut the pipe to a suitable length using a hacksaw blade or knife. Ensure that the surface is not damaged, leave 1-2 mm of the outlet pipe outside the wall surface. 11 - Install Frame/hatch There are two types of frame/hatch depending on whether the cabinet is built into or installed externally on an inner wall. On delivery the hatch is fitted with a screwdriver latch, though an LK key latch is also available as an accessory (LK-no 327 85). 11a - Install Frame/hatch UFH INB When the cabinet is built into a wall, the LK Frame/hatch UFH INB 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. Install the LK Frame/hatch using the M5 screws provided. If the cabinet is installed so far into the construction that the screws are too short, then these should be replaced with longer screws (not included). 11b - Install Frame/hatch UFH UTV When the cabinet is installed externally on a wall, the LK Frame/hatch UFH UTV is used, which fits edge to edge with the outsides of the cabinet. 7 (11)
Installation of LK Shunt Cabinet VS2 Prefab The cabinet is installed in accordance with the instructions above with the exception of the installation of the LK Manifold RF and the LK Manifold Shunt VS2, which are already assembled on delivery. Plate and screws for the LK Frame/hatch UFH UTV Install the frame using the screws and mounting plate provided, see picture above. Fit the four white cover plugs on the end of the cabinet. Assembly aids Assembly is easier with the LK Cabinet Stand The back of the cabinet is fitted with four anchor points (M8 nuts) which can be used to assemble the cabinet before the concrete base is cast. The LK Cabinet Stand can be used as an aid and is assembled as below. 12 - Install Base With an external installation of the LK Shunt Cabinet VS2, install the LK Base by first pushing the upper part of the base into the intended grooves in the cabinet frame. Also ensure that the drainage elbow runs through the intended hole. The lower part of the base is then pulled out to the floor. When the correct height is reached, then the installation is fixed using screws on the front of the base. Adapt the length of the drainage elbow to the outside of the base and install the outlet plate. LK Cabinet Stand with anchor clips. LK Base installation Outlet plate fitted on base Mount the four M8 nuts provided in the back of the cabinet. Attach pipe fixings to the extended bolts. Slip on the round bar and attach the conduit pieces provided with the stand. The conduits stop the stand from becoming set in the concrete, making it reusable. Knock down the round bars through the insulation and into the sand until the installation feels stable. Lift up the cabinet to a suitable height and tighten the fixings. Tape the conduits to the legs of the stand to stop the conduits from moving when pouring the concrete. 8 (11)
