ACO EuroCoverINSTALLATION GUIDELINESInstallation procedureGeneralAllow sufficient time for mortars and concrete toreach required minimum compressive strength.Step 1Ensure the supporting structure and / or theground conditions are adequate to support theexpected operating service load.The frame assembly must be continuouslysupported along its entire length and width on amortar of minimum compressive strength30N/mm 2 to a minimum depth of 10mm.Position the top edge of the rigid frame assemblyso that it is level with the finished floor, or at amaximum of 1.5mm below the finished floor.Step 2Backfill around the ACO EuroCover, and, if usingACO Building Drainage Vinyl Seal ® with sheetflooring refer to the installation details overleaf.A mastic sealant of bead width 5-8mm isrecommended to the edge of the ACO EuroCoverto ensure a watertight seal.Step 3Place the recessed cover on a level and flat surfaceand fill with a suitable 10mm aggregate concreteinfill of minimum compressive strength of40N/mm 2 . To accommodate various floor finishesthe cover may be filled to within 12mm of thefinished floor level.Step 4Ensure the double seal gasket is clean and inposition. Lift the complete recessed cover intoplace using supplied lifting keys and appropriatelifting apparatus; depending on size and infillmaterial the complete cover may exceed Healthand Safety Regulation lifting recommendations.Lubricate and insert all 4 fixings, locating eachpositively before tightening. Fasten down the coveruntil resistance is felt, observing the followingsequence: top left hand, bottom right hand,bottom left hand, top right hand. Finally tightena further one quarter turn.Step 5Insert supplied grit seal between the recess coverand frame.ACO EuroCover installation diagram2 1 26 3 4558 761 ACO Building Drainage Vinyl Seal ®5234Sheet flooringSpecified floor material, maximum depth12mm, for example: ceramic tile, epoxy,polyurethane or concrete screeds.Removable grit seal678Mastic sealantFinished floor level maximum 1.5mm aboveACO EuroCover.Bearing width of mortar bed.10mm aggregate concrete infill of minimumcompressive strength of 40N/mm 2 to within12mm of finished floor level.

ACO EuroCoverINSTALLATION GUIDELINESACO Building DrainageVinyl Seal ®Step 1Ensure the assembled rigid and flexible Vinyl Seal ®sits square and horizontal in the ACO EuroCoveredge detail.Step 2Install the ACO EuroCover into the groundensuring that the flooring screed is flush to the topedge of the rigid PVC extrusion. Protect the ACOEuroCover and seal assembly from splashes ofconcrete/screed.Step 3Depending upon the installation, additionalsuitable fixings may be required to secure the rigidextrusion to the floor substrate. If this should berequired, separately drill and countersink the rigidextrusion making sure that all fixings are finishedflush with the top of the extrusion.Step 4Grout any voids at connecting rigid PVC joints atmitred corners, straight joints or fixings, to ensurea continuous supported floor finish.Prior to laying the vinyl sheet flooring, peel theprotective film from the rigid extrusion (a knife maybe required to cut the film adjacent to the flexibleseal) and ensure all surfaces are clean and dry.Apply a compatible adhesive also to the top surfaceof the rigid PVC extrusion, for example, Altrofix 19two-part water resistant eurethane adhesive, takingcare not to apply adhesive to the flexible seal.Lay the sheet flooring against the flexible seal edgeand prepare the welded joint between the flexibleseal and vinyl sheet flooring as normal by scoringthe sheet / seal joint to approximately half thedepth of the sheet flooring thickness.Either in-colour or black welding filler rod may beused to weld the joint. Remove surplus weldmaterial from the joint using a spatula when thewelded joint has cooled.Channel Edge Flexible seal Heat welded joint(Patent applied for)Vinyl sheet flooring(2-4mm thick) Floor adhesiveRigid seal extrusionOperation and MaintenanceFor general maintenance and cleaning of stainlesssteel refer to ACO Building Drainage Eurogully orModular channel catalogues.To remove the recessed cover remove the push fitgrit seal, then undo hexagonal cap screws. Undogradually observing the sequence in step 4 ofinstallation instructions. Insert lifting key fully intothe cover at two or more points. Lift withappropriate apparatus. To replace the cover followstep 4 of installation instructions.NBS Specification Clause ReferenceFor relevant NBS specification, refer to NBS SectionP31 holes/chases/covers/support for services,Clause 370 access covers/gratings and insert theappropriate model reference number.7
