Cleaning the filter………………………………………………………………….08ManualVolume Filter VF2, VF3, VF4, VF6Maintenance advice:Once a year flush out the sump and manhole with a hose. The sump can be emptied through a littleorifice in the sump floor if absolutely necessary. Therefore the inlet to the tank should be sealedtemporarily or drained to the chamber floor.The lamella unit can be cleaned with a high pressure cleaner, but take care not to hold any lancetoo close to the delicate mesh, lest it damage the mesh itself.07Cleaning the filter:Monitor the filter regularly, clean if necessary.Removal of lamella filter unitManualVolume Filter VF2, VF3, VF4, VF6Installation advice:We recommend you remove the filter mesh unit(s) before installation and store safely. Install the 4 threaded boltfeet, length c. 25 cm, and lower the filter into the manhole.Now push the connection pipe (and seals) through the manhole wall into the corresponding sealingrings of the filter. Small height differences are then accommodated using the the adjustable feet(threaded bolts).Check, with a spirit level, that water will be level in the filter’s receiving sump for optimalperformance.We also recommend covering the filter during installation to keep it clean (during any setting ofconcrete rings and lid etc.)Optimal installation situation:Bypass and inlet feed to both sides of filter. High security due to bypass installation, because of thisyou can connect the filter to larger roof areas. Higher efficiency is obtained if you use inlets on bothsides of the filter.06IncomingrainwaterInletrainwaterFilteroutletto storage tankOutlet tosewer Overflowstorage tankInletrainwaterControltankRainwaterstoragetankManualVolume Filter VF2, VF3,VF4, VF6 VF4 Installation VF6 Installation03Filter InletRainwaterOutlet tosewerOutlet tostoragetankA inmmB inmmC inmmD inmmE inmmF inmmG inmmMeshsizeMin ØmanholeMaximumRoof AreaVF2 1 x DN2001 x DN2001 x DN 150 670 540 525 390 325 275 320 0.4 x 1mm1000 1200 m²VF3 2 x DN2001 x DN2001 x DN 150 670 540 525 980 325 275 880 0.4 x 1mm1200 1500 m²VF4 2 x DN2501 xDN2501 x DN 150 670 540 575 980 325 275 880 0.4 x 1mm1200 2300 m²VF6 2 x DN2501 xDN2501 x DN 200 670 540 575 980 325 275 880 0.4 x 1mm1200 3000 m²12345How it works:1. As rainwater arrives the water level builds up,and flows evenly across the filter sump lip.This ‘weiring over’ ensures water isdistributed evenly across the whole width ofthe highly self cleaning filter cascade.2. Pre cleaning through the cascades. Largerdirt particles are washed across thecascades directly to the sewer.3. Pre filtered water then flows over thesecondary mesh filter. Due to the innovativestructure of the 3P sieve mesh, any dirt iswashed directly to waste which means thefilter is highly self cleaning and lowmaintenance. Debris cannot sit on 3P Filters.3P Volume Filters VF2, VF3, VF4, VF6 for installation in buildings with large roof areas.4. The filtered water flows through a DN 150 /DN 200 outlet into the storage tank.5. Dirt passes through to the sewer.ManualVolume Filter VF2, VF3, VF4, VF604UsageRainwaterInlet ManholeWaste waterOutletOverflowCalmed InletStorage Tank Storage Tank Storage TankCleaned waterInstallation guide:ManualVolume Filter VF2, VF3,VF4, VF605Manhole: Chamber diameter 100 or 120 cm.We recommend installing the filter in its working location. From experience in the “realworld” we recommend use of short connection pipe lengths (rocker pipes) to anymanhole chamber, pushed in from the outside through the chamber wall inlets into thecorresponding connections of the filter. This will help to minimise the risk of theconnecting pipes or seals being displaced during the subsequent constructionprocess. (settlement etc.)When connected up at a construction site please make ensure that all seals are setcorrectly. The pipe should not project into the filter more than 5 cm. The filter shouldbe installed perpendicular and horizontal. There are adjustable feet to accommodatesmall height differences. The manhole itself should be set level. The manhole chamberbase should ideally have a gradient of approximately 5% or more towards the outlet towaste or to sewer. This ensures any sediment is more easily rinsed away.We recommend that the distance between the base of the manhole floor and the lowersump in the filter should be at least as big as the diameter of the filter rainwater inletpipe. However, this is not absolutely necessary.You can adjust this distance with the help of the adjustable feet (the threaded bars).You may wish to have your installer/drainage contractor prepare the manhole chamberaccording to the following dimensions. The diameter of the chamber wall orifices willdepend on the selected seals for the pipes.Outlet to waste:Base of outlet pipe = base of manhole floorOutlet to storage tank:Invert of outlet pipe = x cm above floor of manhole chamber (see Table on pg 3 fordata)2x inlet rainwater:Invert of 2 No inlet pipes = 32 cm from invert of pipe outlet to storage tank, which istherefore ideally 57 cm from base (floor) of chamber.
