Covers are produced from grade 304 stainless steel or galvanised mild steel. Grade 316 stainlesssteel is used only on request. Covers are gasket-sealed, screw-fixed and delivered with handles. A special jacking key guarantees easy lifting of the cover from the frame. A wide range of sizes andload resistances make these covers ideal for normal use in outdoor or indoor applications.

Covers are produced from grade 304 stainless steel or galvanised mild steel in a wide range of sizesup to load class C250. Covers are gasket-sealed and screw-fixed with hinges and gas springs, whichguarantee the easy opening of the cover by one person. A safety device prevents the cover from spon-taneously closing. The gas springs must be installed after concreting and the concre-te has set!

Covers are produced from aluminium and magnesium alloys. Covers are gasket-sealed and screw-fi-xed. The unique non-welded shape of the frame and cover make for easy installation. Double sea-ling and an additional grit seal are standard. The weight is reduced to the minimum but provides thesame mechanical resistance as a standard aluminium cover.

ACO TopTekInstallation instructions

These instructions are for the following types ofcovers: ACO TopTek GS/SS/AL in standard de-sign, ACO TopTek GS/SS/AL MULTI/ASSIST/PAVING/SOLID.ACO TopTek access covers are destined for thehorizontal installation, the tray is up. Covers aremade from aluminium, hot dip galvanized mild

steel and stainless steel in different load classesaccording to EN 124. They are divided accordingto the filling material to the covers with checkeredsteel, the covers filled by concrete and the coversmade for filling by the paving. The covers are wa-terproof and smell proof. The covers should notbe used while the temperature is above 70°C.

Covers are delivered as screwed assembly; it means that the cover is attached by thescrews to the frame. Before the installation,the cover should not be dismounted, becausethe there can be further problems with openingthe closing. 1. Verify that the cover is attached to the

frame and that the setting blocks are cor-rectly located between the cover and theframe (the setting blocks are not deliveredwith the covers Alucover, the stuffing deter-mines the play between the frame and thecover).

2. Protect the screws and the borders of cov-er and frame against the stain by concrete.Afterwards it is very difficult to remove it.For the aluminium covers where we add theadmixtures to the concrete mixture, for ex-ample the frost free or accelerating sub-stances, we recommend that the surfacesexposed to the concrete are at firstequipped with the primer epoxy or asphalt

coat for long-term protection against rust. 3. Install the built up frame and cover to the

requested level. The construction hole forinstallation:• Perimeter: +150 mm to the external di-mensions of cover• Depth: +40 mm to the high of coverNote: For aluminium covers where additivesare used in the concrete mix, for example,anti-freezing or accelerating agents, it isrecommended that surfaces exposed toconcrete are first primed with either anepoxy or bitumen paint to protect from longterm corrosion.

4. The anchors of the frame must be rangedso that the correct anchorage of the builtup frame with the concrete is assured.

5. After the effusion by the concrete in theconstruction hole and its induration fill upthe construction hole and the cover by con-crete C35/45 (according to EN 206). Mixthe mixture while the temperature is 15-

20°C and pay attention that the mixturewould not been too wet (for example theconsistence category S2). Verify before theeffusion that the underlay is not in contactwith the base of cover. If you have the cov-er Alucover, control that the underlay isclosed in the plastic holders. If the holdersare not part of the supply place the under-lay on the bottom of cover so that the pro-tection is 15-20 mm. Fill the covers des-tined to the paving by the paving.

6. Spread equally the mixture of concrete inthe cover by using tamp regarding the finaldepth of the finished surface. Note: it is nota defect if the surface of the underlay isrusted. The rust helps the connection be-tween the underlay and the concrete.

7. When the mixture reaches about 90% of itsfixity, uncover the cover and clean properlythe surfaces of the cover and the frame ofconcrete.

4.) Opening of the cover:

The covers are delivered with the accessoriesneeded to its opening. Process:1. Remove the protection of screws. 2. Unscrew the screws by which the cover is

fixed to the frame by the help of deliveredimbus key, eventually by the lifting key.

3. Screw on the lifting keys to the preparedscrolls in the protection of cover. Now youcan take out/lift off the cover from theframe. In the case of bigger covers it isnecessary that the cover is lifted by morepeople. After the removing/lifting out pay at-tention on the damaging of the floor. Whileremoving/lifting out for longer time assurethe exposed shaft by the underlay.

4. The covers with auxiliary gas struts are as-sembled by the help of plugs and cotterswith the first opening. The protection mustbe fully pushed for assuring the safety fuse.

5.) Closing of the cover:

1. Before the closing of the cover it is neces-sary to clean up the frame and the stuffingso that the water tightness of the cover isassured. Control that the stuffing is notdamaged. If it is necessary change thestuffing.

2. Close the cover in the frame.3. Screw out the lifting keys.4. Screw up the crews and the set to them the

plastic protection.

6.) Care and service:

At least twice a year remove the cover andclean the frame and the cover by clear water.Before the return setting treat the frame andthe screws by the suitable grease. During the setting protect the filled coveragainst the freezing and the rain and keep theconcrete incubate for a period of 48 hours be-fore further manipulation. The complete fixitywill be reached after 28 days.

7.) Replacement parts

If you command the replacement parts, men-tion not only the type of the part, but also thetype of the shaft cover. It is possible to command the following re-placement parts:• Protection camping strips • Imbus screws• Stuffing• Lifting keys• Imbus keys

3.) Process of installation:

2.) Accessories

• Protective capping strips • Screws with inward hexagon • Lifting keys with or without imbus• Imbus key (if the lifting key is without imbus)• Setting blocks (they are not delivered with

covers Alucover)

Covers are produced from 3-mm-thick galvanised mild steel. Strong supports are welded under thebase plate, which guarantees load resistance without any additional concreting. The 20-mm concre-te bed is reinforced with wire mesh and is only for the precision placing of pavement blocks.

Covers for pavement (according EN 124) – Installation instructions and maintenance manual

Installation Method• Ensure the cover is assembled in the frame

and the spacer blocks are in position between the cover and the frame.

• Protect the locking screws and the periphery ofthe frame against concrete splashes. This canbe very difficult to remove it at a later stage

• Install the assembled cover and frame in position to the required level. Use aspirit-level.

• The anchors attached to the frame must beextended to ensure the assembled cover andframe are reliably anchored into the finishedconcrete surround.

• The gap must be filled with B 30 concrete.• Loading of the cover can take place after the

concrete has hardened min. after 72 hours.If necesseary, rapid-hardening concrete canbe used.

• After the concrete has hardened, open thecover and clean all concrete remmants fromthe frame and cover in the area of fitting andsealing.

• Fill the cover with paving, laid in concrete bed.

Maintenance• Clean frame and cover every time the cover

is removed.• Prevent the slot from leakage some silt or

other dirt.

General instruction• The required loading class is achieved with-

out concrete infilling of the cover (accordingEN 124)
