1. Form rebate to size (to support the frame)
2. Position access cover in rebate
3. Check unit is level and not rocking
4. Pour & vibrate concrete around access cover, and in cover if concrete filled recessed cover is used
5. Level and finish concrete, lay pavers or pavement materials. Urbanfil®/ Pavermate® covers are filled with concrete to minimum depth of 45mm as concrete is integral to strength of these covers. ACO does not recommend tiles deeper than 25mm in Urbanfil®covers and pavers more than 40mm deep in Pavermate®covers.
a. Recessed pan depths;
i. Urbanfil® - 85mm,
ii. Pavermate® - 135mm,
iii. Rhinocast® - either 12mm or 40mm dependent on steel edging height.
Refer to notes beneath parts list table
6. Allow concrete to cure before removing cover – early removal may cause twisting of frame
ACO sells lifting keys dependent on lid or cover type. Refer to accessories.
