1. The Fusion Oxi-Gen system will produce iron, sulfur, manganese free water immediately
after installation. Depending on the raw water quality there may be contaminants built up in
the water heater, plumbing system and other devices. Over the first few weeks as water is
used there could be traces of this build up that are being removed by the newly installed
system. This typically clears up after a couple weeks.
2. Depending on the contaminants being removed there may be iron bacteria or sulfur reduc-
ing bacteria in the plumbing system prior to the Fusion Oxi-Gen install. This bacteria can
potentially survive after the Fusion Oxi-Gen installation. This is usually indicated by a sulfur
smell that will appear after a few weeks of initial usage. If this is the case, the well and en-
tire plumbing system will need to be chlorinated to remove any existing bacteria. If the bac-
teria is not removed, it will begin to “grow” backwards toward the treatment system and the
sulfur smell will not go away. If this does occur, it is easily eradicated with a chlorination
well “shock” procedure. Ask a US Water Systems representative about our well sanitizing
kits.
3. There may be “bubbles” in the water for a few weeks after installation. A few bubbles are
fine, but if there is “fizz” that remains for several seconds, it is an indication that the system
is being overfed with H2O2. This occurs because after installation the water will become
cleaner after the plumbing system has been flushed and the initial dosage of H2O2 may
need to be adjusted to compensate for the lower contaminant level.
Pressure Tank
If the plumbing system uses a bladder pressure tank it will be in the system prior to the Fusion
Oxi-Gen system. This tank should be drained periodically to remove any build up of contami-
nants. Typically once a quarter is sufficient but that frequency may need to be increased on
systems with high contaminant levels.
Injection Pump
The internal pump tube and injection duck bill check valve may need to be replaced periodical-
ly. They typically last 1-5 years depending on the usage. There is a spare tube shipped with
the system and instructional videos explaining how to change the tube at
www.USWaterSystems.com. Replacement duck bill check valves can be purchased at
www.USWaterSystems.com as well.
Catalytic Carbon
The Catalytic Carbon is virtually maintenance free. However, if there is a power outage the
clock and other settings need to be checked to ensure the filter will backwash properly at the
proper time of day. It is crucial that the Catalytic Carbon backwashes at a time when there is
no water being used in the house or contamination of the plumbing system can occur. This
media typically lasts 3-5 years in most applications before it is exhausted.
