The air in the <br /> cartridge is disp;aced by the water and pur�ed from beneath ihe fiiter hood through the one-way <br /> ch�ck valve locat=d in Ihe cap. Once the center tube is fille@ with waler(approximately 16 inches <br /> deep), there is enough buoyant force on the floai tn open the float vaive and alloH�the treated water in <br /> �hP c:enier tube to fioH� into the under-drain manifold. This causes the checl; valve to close, iniiiatino a <br /> siphun Ihat draws polluied water throughout the full surtace area and volume of the fiifer. Thus, the <br /> entire fifter cariridge is used to nHer water fhroughoul Ihe duration of Ihe storm, regardless of the <br /> water surface el=vatior in the unft.

Since some <br /> used is potentia0}� buoyant, a threaded connector affixed lo the under-drain manifold (with alue or <br /> oth�r adhesive) is necessary fo ensure that the cartridge isn'i lifted oul of place. ror the hea��iemedis <br /> ��'npost medis, a slip conne�tor is used. <br /> i h= SlormFilter is 21so equipped with flou�spreaders iha� Irap flaating debris and suriace nims, even <br /> durin9 o�re�ov,� condition: Depenoing on individual site characterisiics, som= systems are eoui <br /> �riih hiph and�or bass floia�bppasses Hioh iloµ bypasses are instaliec v��her the �aiculaieo � <br /> 5[Offll �Vc'Il1 U@f12�21Qc g fION'II78� OVCfCOff185 �I1P 01BrIIDN�capa:;jl)' Oi�hB S)'stem.
