2 Geberit Syphonics Geberit Pluvia is the leading syphonic roof drainage system used throughout the world. Architects, Consultants and Contractors have Examples of the 3 Outlet Types Available (See following pages for other variations of outlet) Series 7 (max 12l/s capacity) Series 7 Outlet in a Steel Profile Roof Deck (without Vapour Barrier Clamping unit) chosen the system for some of the most prestigious and ground breaking building Joint foil to suit membrane (see page 3) Pluvia Outlet Roof Membrane Thermal Insulation Vapour Barrier designs due to the freedom and flexibility it provides. Pluvia uses the ingenious gravity induced vacuum principle to create a syphonic action, which allows the complete drainage of a roof area with smaller diameter pipes than used in a conventional gravity system. Geberit Pluvia Advantages No slope in pipework required Less underground pipe Less sitework Fewer pipes and fittings Steel Roof Profile Decking 90 0 Bend Electroweld Coupling and Brackets (Creating on Anchor Point) Geberit Pluvia Rail System Series 7+ (max 25l/s capacity) Series Litre Outlet in a Concrete Slab Roof Pluvia Outlet Geberit PVC Coated Outlet Flange bonded to PVC Roof Membrane (This outlet is also available without PVC coating for other roof finishes Reduced pipe dimensions Less space required Self cleaning action Quick and easy fastening system The only system to be fully BBA Accredited Concrete Slab Series 5 (max 6l/s capacity) Series 5 Outlet - 56mm(6 L/s) with PVC Roof Finish Pluvia Outlet Geberit PVC Coated Outlet Flange bonded to PVC Roof Membrane CD-ROM available with installation details of various outlets and roof configurations.

Tension wedge for sliding and anchor bracket (electro-galvanised) Mounting plates (electro-galvanised) 1/ Electroweld Tapes ød Electroweld tapes are an alternative method of creating an anchor point, see page 7 for details. 5

7 Pluvia Rail System The Geberit Pluvia rail system was developed for the installation of horizontal pipework. Advantages of the rail system Quick installation Fewer ceiling fastening points Controls thermal movement No expansion because of rigid installation No expansion sockets in the horizontal pipes Simple prefabrication is possible One fastening for anchor and sliding brackets The expansion and contraction of the pipework is prevented by the rail system, the properties of HDPE allows rigid fixing. G Pluvia Rail Support Angle Bracket Allows T connections using single studding drop Locks rail together providing a true anchor point Quick and easy to install Pluvia Rail Threaded Rod M10 Tension Wedge Pluvia Bracket Connector to Rail Rail Clamp

Chamfering the inserted pipe end to approximate Check the scale on the outer surface of the expansion socket for insertion depth. 3. Mark the correct insertion depth on the pipe. 4. Lubricate the pipe end well with soft soap, Silicone or Vaseline. N.B. Do not use oil or grease which can damage the rubber seal. Table A Dia mm Vert. m Ø Max. 6m Using expansion joints Expansion Joint For spacing between guide bracket see table A Expansion Joint Example: Insertion depth in an ambient temperature or 20 C (vertical assembly) Rigid fixing Anchor point with electroweld tape Max. 6m Fixings must be strong enough to resist forces of thermal expansion (See application guide for HDPE for data) Sliding brackets Fixings must be strong enough to resist forces of thermal expansion (See application guide for HDPE for data) Anchor point with electroweld tape For spacing between guide bracket see table A 8

11 Maintenance Geberit recommend that a maintenance programme is always implemented on completion of the project. The intervals between inspection will depend on the location of the building. The maintenance programme should include: Clearing of all outlets of any debris or silt as shown in figure 1. a Remove lid b + c Remove function disc d Rinse function disc with water Check that no pipes connecting to outlets are blocked with silt etc, if blockages are found they can be removed by using a water jet through the outlet after removing the top unit and function plate (a, b & c in figure 1) Ensure all outlets have gratings and tops in place. `order spares from Geberit if necessary. e Wipe outlet with cloth d a c b b e Figure 1 Testing of System On completion of a Geberit Pluvia System the integrity of all joints must be tested using an air test as described in BS EN 12056, which in general requires a 38 mm air test for 3 minutes. If the installation has been designed using the Geberit software it is not normally necessary to performance test the installation. Third party approval by the BBA included verification that the software is a true reflection of the actual flow performance. 10
