Installation guide & sitework details
These details are intended as a general guide to correctinstallation - it is appreciated that site practice can varydepending on the design of slab, type of finish etc.
Further advice is always available from our TechnicalDepartment who can be contacted between the hours of 9 am and 5.30 pm on 01920 463230, or alternativelyyou can email them at [email protected].
PreparationCovers are supplied ready for installation internally without furtherpreparation. In external locations, or those that may be permanentlywet, all aluminium surfaces in contact with concrete should receivetwo coats of bituminous paint.
Single covers1. The cover should be placed into the outer frame and securing
bolts screwed in loosely if applicable. For stainless covers bend out anchor lugs.
2. The whole assembly should be bedded down to the correct level. Haunch mortar up on outside of outer frame, to prevent any possible distortion of outer frame when surrounding floor finish is laid.
3. Leave the bedding mortar to cure, then complete the surrounding floor finish.
4. The cover should now be filled (with the exception of the 5 Bar series) without removing it from the outer frame, and using spacers provided between cover and frame. (Note that the designloading and if applicable, fire resistance can only be achieved if the infill is equivalent to the 28 day cube strength of OPC concrete of 40 MPa.)
5. When properly set remove cover and clean taking care not to damage any seals. Make good pointing to the underside of the outer frame. Replace cover.
Duct covers1. The outer frame will be either of one piece construction if size
permits or sectional if large. If it is sectional several covers will have been screwed into the outer frame sections (these should now be loosened) to pre-space to the correct span dimensions if possible. If the unit incorporates steel beams, the beam receiving pockets (if not already attached to the outer frame) should be fitted using the screws provided. Fix stop ends to the end of the outer frame section with connecting spigots supplied.These are only for the purpose of locating one length of outer with the next and are not intended to provide a full strength joint.
2. Fix anchor lugs to the outside edge of the outer frame by crimping with pliers at approx. 600 mm (24”)centres. For stainless covers, bend out anchor lugs.
3. Place all of the removable cross members into position, (if fitted)then bed frame down to correct line and level, (if the frame is sectional working away from the stop end) making sure that the frame remains straight and is not distorted in any way. If universalbeams are incorporated they require levelling by placing packing mortar between base of beam pocket and loose beam seating plates supplied.
4. As work proceeds place loose covers into duct frame to check that the gap between the outer frames is correct making sure that spacers supplied are used between cover and frame to maintain a minimum 1mm joint.
5. When outer frame is properly set remove any “spacer” covers that have been screwed into the outer frame and place in correctposition in the duct frame along with all of the loose covers making sure that spacers are used to maintain a minimum 1mm (1⁄32”) joint between the cover and frame, and bolts if fitted
are screwed in loosely. The covers may now be filled (with the exception of the 5 Bar series) and the floor finish to the outside of the outer frame completed. Again taking care not to distort either the cover or the outer frame sections. Larger span covers may require propping from below to prevent distortion caused by the weight of the wet concrete infill. (Note that the design loading and if applicable, fire resistance can only be achieved if the infill is equivalent to the 28 day cube strength of OPC concrete of 40 MPa).
6. When properly set the covers should be removed, and cleaned taking care not to damage any seals, the joint between the cross members, (if fi tted) and outer frame should be sealed with mastic.
HSE 75 series1. Remove the hinge securing bolts, then lift out the cover from
the outer frame. Assemble the lower gas spring fixing brackets with the outer frame using the bolts supplied.
2. Bed the outer frame on mortar to the correct line and levelensuring that the lower gas spring brackets are in contact with the vertical concrete face of the pit wall.
3. Mark and drill the 8 fixing holes through the lower gas springbrackets into the vertical concrete face of the pit wall, and then bolt to the concrete using suitable fasteners.
4. At this stage the cover should be positioned within the outer frame and the hinges bolted to outer frame, the safety stay should also be attached using the bolts provided. The hinges should now be adjusted to provide a minimum 1mm gap between the cover and frame (stainless version only), the spacers provided should be used to maintain the minimum 1mm gap. Haunch mortar up on outside of outer frame, to prevent any possible distortion of outer frame when surrounding floor finish is laid.
5. Leave the bedding mortar to cure, then complete the surrounding floor finish.
6. The cover should now be filled without removing it from theouter frame. (Note that the design loading and if applicable, fire resistance can only be achieved if the infill is equivalent to the 28 day cube strength of OPC concrete of 40 MPa.)
7. When properly cured the cover should be lifted with care usingthe keys provided making sure the safety stay engages. The cover and frame should be thoroughly cleaned taking care not to damage any seals or intumescent strip fitted. Make good pointing to the underside of the outer frame.
8. The gas springs should now be screwed into position, thenthe cover can be gently lowered and locked into the closed position.
Lifting and maintenance procedures1. Remove all bolts from the lifting points using key provided
except the 5 Bar series where the bolts should be loosened.2. Screw in by 12-15 mm (1⁄2 - 3⁄4”)a lifting key into each lifting point
except the 5 Bar series where the key should be positioned under the bolt head. A lifting device should be used where the weight to be lifted exceeds the Manual Handling Operations Regulations 1992.
3. Lift out cover without dragging across outer frame to avoid damage.4. Clean thoroughly both the seating and cover checking the
condition of the double base seal and intumescent seal if fitted, also checking the top edge dirt seal. Then re-treat the underside of the cover with waxoyl or similar inhibitor if required.
5. Check condition of gas springs on HSE 75 series.6. Replace cover carefully and insert all securing/plug bolts taking
care not to over tighten.
Should any of the seals, bolts or other removable componentsbe damaged or missing they are available for replacement.

Installation guide & sitework details
Visedge series access covers – Single coversSet the cover in the outer frame, fitting the securing or blankingbolts supplied. Maintain a 1 mm (1⁄32”) gap between the cover andthe frame sections.
Lay the screed up to the outer frame, ensuring that the PVCextrusion is kept clean.
When the screed has cured and the installation of the sheet flooringis about to commence, remove the protective tape from the PVCextrusion on both the cover frame and the outer frame. Cut theflooring material up to the upstand of the PVC extrusion on theouter frame and lay into position, using adhesive as necessary. In similar manner cut the flooring material within the cover frameup to the upstand of the PVC extrusion and under the clamping ferrules around the lifting/locking bolts, and bond with adhesive.The floor finish should then be welded, in accordance with the manufacturer’s instructions, to the top edge of the PVC extrusions,on both the cover frame and the outer frame. Screw down theclamping ferrules until they are flush with the floor finish.
Finally lift out and clean the cover. Point the underside of the framewith 1:3 cement/sand mortar, if necessary. Replace the cover and tighten the securing bolts.
Remember to leave the lifting/locking keys with the building owner.
Visedge series access covers – Duct coversThese are installed in a similar way to the duct covers for the5000 and 7500 series. See previous page.
Visedge DS edge trimWhen the flexible flooring has been fixed, cut the lengths ofVisedge DS to suit the floor layout. Starting from one end, place a length of trim in position and mark the floor throughthe countersunk holes in the trim, then drill and plug the floor. Whenready to fix the trim, apply some epoxy adhesive to the underside of the trim, then carefully position the trim and screw down.
Visedge VR edge trimMark out the floor to define the junction between the hard pavingand the sheet flooring, i.e. the extremity of the aluminium upstandof the Visedge VR trim. Cut lengths of trim to suit and place in position. Mark the floor through the countersunk holes in thetrim, then drill and plug the floor where applicable. The Visedge VRtrim should now be screwed into position taking care to keep thecorrect line and level. The hard paving, e.g. ceramic tiling, and thevinyl floor screeding can now be laid as necessary. It is importantthat the pvc insert is kept clean and that the protective tape remainsintact and is not removed until the floor finish is ready for bonding.Cut and fit the vinyl sheet flooring to the Visedge upstand, bondand weld.
If in doubt, contact the Howe Green Technical Department,who will be pleased to assist.
