If your level of Hydrogen sulfide is unknown (it is hard to accurately test for) and you have a
noticeable "rotten egg" odor, assume a Hydrogen sulfide level of 0.5 ppm. If the rotten egg odor
is severe, assume a level of 1.0 ppm.
and you have a rotten egg smell in your water. Iron Equivalent = (0.8) + (2 x 0.05) + (3 x 0.5) = 2.4

How it Works: Soluble iron (ferrous) and manganese are oxidized and precipitated by contact
with higher oxides of manganese on the media granules. The hydrogen sulfide is reduced by
oxidation to an insoluble sulfur precipitate. The precipitates are then filtered. Ferric iron is
removed by mechanical filtration. No backwashing required!

Typical Installation:
Note: We recommend that this product be installed by a professional plumber. If you
install this product yourself, please ensure that your installation meets all local building
and plumbing codes. The following instructions are meant only as a general guide and
should not be considered a substitution for your local plumbing and / or building codes.
You will need the following plumbing supplies:
two (2) shut-off valves with suitable sized unions to connect to your incoming and outgoing
•
water lines. You can select threaded, compression or sweat (soldered) fittings on the shut-
off valves as desired.
plumber's cement or Teflon tape for all threaded fittings.
•
The plumbing connections on the inlet and outlet of the water filter housings are 1" inside
diameter (female) NPT threaded fittings. You may require additional plumbing adapters to
connect to your selected shut-off valves. Your plumber will have all of these items, or they can be
purchased at your local hardware or plumbing supply store at minimal cost (take these
instructions to the store with you so the store clerk can make sure you get everything you need).
Note: In older homes with galvanized piping all fittings should be threaded.
Example: Test results are 0.8 ppm iron, 0.05 ppm manganese,
