Installation

Class E, F & G covers and frames; the product must not be rebated into position. The product must be cast into the base concrete.

Care must be taken to ensure that concrete is vibrated, particularly under the frame and that concrete both under the frame and inside the cellular frame structure reaches the same Mpa as the base concrete.
Clear opening of the pit must not be larger than the frame opening.
The product must be built into the base concrete and the base concrete must include sufficient reinforcing under and around the frame and in some cases reinforcing must be attached to the frame (ie cases of high back pressure head).
As the manufacturer of the cast iron product, we advise that whilst our product is tested to AS3996 in terms of design load, the frames are designed to be fully encased in concrete of sufficient Mpa to hold the loads indicated.
Havestock Pty Ltd takes no responsibility for the integrity of the product in service where it has not been installed as described in this document. Inadequate installation voids the product warranty.
