Installation of End Caps & Pipe Connections•Prior to installing end caps, remove the appropriate knockout for pipe connections. Snap an end cap on each end of the drain lines with the product or company logo facing out (knockouts can be removed withaknifeora4"holesaw).

•Upperendcap4"knockouts—alwaysusedasinletfor eachline.Afour-inchholesawmaybeused.•Lowerendcap4"knockouts—usedforreturnlinesor continuouscircuitpipingperstateor localcode.These lower knockouts may also be used to create turns in the drain lines greater than the ten degrees provided bythechamberswivelfeature.

•AllArc/BioDiffuserchambersareH–10 load rated. Wherevehicularloadingisanticipated,H–10loading (16,000 lbs/axle) is achieved by backfilling with aminimumof12"ofproperlycompactedcover.

•Do not drive heavy equipment over a system comprisedofnon-compactedcovermaterialwithout first bridging the excavation. Use lightweight or trackedequipmenttopushthesoilontothesystemto theproperheightsetforthbylocalandstatecodes.

Mound Installation Procedure

• Review Plans and stake out the entire leachingbed area. Confirm elevations of the septic tank,distributionboxandchambers.

•Clearandscarifyentireleachfieldareaincludingfillextensions.

•Confirm backfill material meets the Maine 804.2Backfill Standard. Place backfill material and usetheteethonthebuckettomixwiththeoriginalsoil.Placebackfillmaterialin12inlifts(300mm),compactusing a track vehicle. Continue placing backfillmaterialtothebottomelevationofthechambers.

Backfilling

•After chamber assembly is completed, fill to top ofchamberswithpreferablycompactible,slightlylimitedtomoderatelylimitedsoil.

•Backfill material to meet Maine Backfill standard:804.2Backfillstandards:Thebackfillmaterialshallbeacoarsesandtoagravellycoarsesandwhichmeetsthefollowingrequirements:

804.2.1 Coarse fragments: The upper limit ofcoarsefragmentsshallbe3inchesindiameterandapproximately5%byvolume;

•Modestly compact the sidewall area backfill material by simply walking down the sides of the chambers. Sidewall compaction is important to begin the stabilization process of the soil, to support the chamber sidewalls, and help prevent fine sand migration into the chamber louvers. This procedure may be accomplished any time duringtheinstallationorcoveringprocess.
