Proper Installation
This water filtering system must be properly installed and located in accordance with the
Installation Instructions before it is used or the warranty will be void.
 Do not install or store where it will be
exposed to temperatures below freezing or
exposed to any type of weather. Water
freezing in the system will break it. Do not
attempt to treat water over 100°F.
 Do not install in direct sunlight. Exces-
sive sun or heat may cause distortion or
other damage to non-metallic parts.
 Properly ground to conform with all govern-
ing codes and ordinances.
 Use only lead-free solder and flux for all
sweat-solder connections, as required by
state and federal codes.
 Maximum allowable inlet water pressure is
125 psi. If daytime pressure is over 80 psi,
night time pressure may exceed the maxi-
mum. Use a pressure reducing valve to re-
duce the pressure.
 WARNING: Discard all unused parts and
packaging material after installation. Small
parts remaining after the installation could
be a choke hazard.
The Fusion Oxi-Gen system provides iron and sulfur removal throughout the home. The Fusion
Oxi-Gen system should be installed at the point of entry to treat the entire home, both hot and
cold water.
The Fusion Oxi-Gen system’s backwashing tank removes iron and sulfur using oxidation.
When water is used in the home, hydrogen peroxide is injected in the Fusion Oxi-Gen feed to
create super oxidation during operation. The Catalytic Carbon media in the Fusion Oxi-Gen
system tank provides filtration when the system is in service to collect contaminants oxidized
by the hydrogen peroxide. These contaminants are backwashed from the media surface when
the system regenerates.
Fusion Benefits
 Iron & Sulfur Removal
 Virtually maintenance free.
 Improves the efficiency of water-using appliances
 Simple installation
 Safe for landscaping and lawn watering.
 Compatible with all on-site and community wastewater treatment systems

US Water has pioneered the use of hydrogen peroxide in water treatment for the eradication of
iron (rust) and sulfur (hydrogen sulfide odor) for nearly 20 years. It can truly be called an
"Eradication System" because it TOTALLY removes iron and sulfur. Properly sized, a Fusion
Oxi-Gen Hydrogen Peroxide System from US WATER is THE MOST EFFECTIVE METHOD
for removing iron, rust, sulfur and hydrogen sulfide (the rotten-egg odor) from the water supply.
The Fusion Oxi-Gen system uses Catalytic Carbon media in the backwashing filter to collect
the contaminants removed by the hydrogen peroxide. Hydrogen Peroxide is not a hazardous
chemical - to the contrary, hydrogen peroxide (H2O2) is composed of the elements of water:
Hydrogen and Oxygen. There is nothing foreign or chemically added to the water supply.
Unlike chlorine, hydrogen peroxide requires no contact time and the reaction (oxidation of iron,
rust, sulfur and hydrogen sulfide) is immediate. The Fusion Oxi-Gen Hydrogen Peroxide
System is the answer to practically any iron, rust, sulfur or hydrogen sulfide problem, and is
backed with our 90-Day 100% Satisfaction Guarantee. US Water Systems guarantees 100%
iron and sulfur removal with its Fusion Oxi-Gen System which utilizes Hydrogen Peroxide or
H2O2.
Hydrogen peroxide or H2O2 is a powerful, yet
versatile oxidant that is both safe and effective.
Considering the H2O2 advantages, it’s easy to
see why this is the ONLY sure way to eradicate
iron and sulfur.
Powerful - H2O2 is one of the most powerful
oxidizers known and is much stronger than
chlorine, chlorine dioxide, and potassium permanganate.
Safe - H2O2 is formed by the action of sunlight on water and is a natural purification system for
our environment. Consequently, H2O2 has none of the problems of gaseous release or
chemical byproducts that are associated with other chemical oxidants. And since H2O2 is
totally miscible with water, it reverts back to hydrogen and oxygen after the reaction is
complete.
Versatile - Hydrogen Peroxide is lethal to iron and sulfur. PERIOD!
Selective - In itself, H2O2 is a fantastic oxidizer, much better than chlorine and potassium
permanganate. It poses no health hazard and ERADICATES 100% OF THE IRON AND
SULFUR – ALL THE TIME – GUARANTEED!

System Overview and Specifications

The Fusion Oxi-Gen iron and sulfur eradication system uses Hydrogen Peroxide (H2O2) to
oxidize contaminants in the water source. The chemical name for hydrogen peroxide is H2O2.
It is very similar to water (H2O) but with one additional oxygen molecule. Hydrogen peroxide is
injected into the water stream proportionally. The water meter will engage the chemical
injection pump based on the flow rate of the feed source water and the settings on the pump
control.
When water is being used the water meter sends a pulse to engage the pump. So when large
amounts of water are being used the pump will run more frequently during the usage period
than in times when a small amount of water is being used. The standard programming is set to
a 5 second control. At 100% the pump will stay engaged for 5 seconds. At 50% the pump will
stay engaged for 2.5 seconds. In some applications with high flow rates or high contaminant
levels, this setting may need to be changed if a residual H2O2 cannot be achieved. There are
internal settings that can be changed to adjust the output rate. The pump settings can be
changed to 10 seconds at 0-100% or 20 seconds at 0-100% if need be. 80% of the
applications will use the standard setting (5 seconds).
When hydrogen peroxide is injected into the water stream, it oxidizes the iron and sulfur
precipitating it from solution. This reaction is immediate. When these contaminants are
oxidized with hydrogen peroxide (H2O2) the extra oxygen molecule oxidizes the contaminants
and the by product is H2O (water). This is much safer than using chlorine in that chlorine can
cause other problems in the water stream such as chloramines and trihalomethanes (THM’s).
Once the hydrogen peroxide has been injected in the water it passes through the backwashing
Catalytic Carbon filter. The backwashing Catalytic Carbon filter uses Catalytic Carbon media
to act as a “catalysis” to remove the oxidized contaminants. As the water passes through
Catalytic Carbon filter, the oxidized contaminants are removed from the water and collected on
the Catalytic Carbon media. Once the water has passed through the Catalytic Carbon filter,
the water is iron and sulfur free! Some manganese can be removed with the Fusion Oxi-Gen
system buy extreme levels of manganese may require a water softener in addition to the
Fusion Oxi-Gen system to polish the remaining manganese.
The Catalytic Carbon filter will need to be backwashed at a specified/determined frequency. In
some applications this can be extended to 4-5 days. The typical frequency is 1-3 days.
Contact US Water Systems and a Certified Water Specialist will be able to determine the
frequency that can be used when considering the feed water contaminant levels. The factory
default will be 3 days.

WATER PRESSURE: A minimum of 20 pounds of water pressure is required for re-
generation valve to operate effectively.
ELECTRICAL FACILITIES: An uninterrupted alternating current (A/C) supply is
required. Note: Other voltages are available. Please make sure the voltage supply is
compatible with the unit before installation.
EXISTING PLUMBING: Condition of existing plumbing should be free from lime
and iron buildup. Piping that is built up heavily with lime and/or iron should be replaced.
LOCATION OF FUSION TANK AND DRAIN: The Fusion tank should be located
close to a drain to prevent air breaks and back flow.
BY-PASS VALVES: Always provide for the installation of a by-pass valve if unit is not
equipped with one. The Catalytic Carbon is equipped with a bypass valve.
CAUTION: Water pressure is not to exceed 80 psi, water temperature is not to exceed
110°F (43°C), and the unit cannot be subjected to freezing conditions or direct sunlight.
1) Use a piece of duct tape to cover the top of the distributor tube in the tank. Be sure the
distributor tube is centered in the tank. The distributor tube should be flush with the top of
the tank or no more than 1/4” below flush. Install the supplied funnel and pour the gravel
in the tank first. Each system will ship with gravel and Catalytic Carbon media. Pour the
gravel in the tank first then pour in all the Catalytic Carbon media that was shipped in the
tank last. US Water does not ship “extra” media.

2) Lubricate the distributor O-ring and the tank O-ring. Then install the upper basket (the ac-
tual upper basket may look different than the one pictured below) on the bottom of the valve
by lining up the tabs then turning the basket clockwise to lock it in place. Place the upper
basket over the distributor tube and push the valve on the tank. Thread the valve on the tank
by turning it clockwise. Be sure not to cross-thread the valve on the tank. Tighten the valve
hand tight, then snug it further by tapping it with the palm of the hand. DO NOT use tools to
tighten the valve or damage could occur.

1. There is a ball valve on the bottom of the strainer filter sump. This ball valve should be
closed during operation. This ball valve and be used to flush the strainer filter sump period-
ically. This can be done by placing a bucket under the ball valve and opening the valve un-
til the sump strainer is clear.

Any solder joints being soldered near the valve must be done before connecting any piping
to the valves. Always leave at least 6" (152 mm) between the control valve and joints being
soldered when soldering pipes that are connected to the valves. Failure to do this could
cause damage to the valves.
The Fusion Backwashing Filter is equipped with 1” removable connectors. It is recommend-
ed that these connectors are installed in the plumbing fitting using Teflon tape then lubricate
the o-ring on the connector. Remove the red clips and push the connectors into the bypass
valve once they are tight in the plumbing fitting. The red clips can then be re-installed to se-
cure the connectors in the bypass valve.
The inlet and outlet can be identified on the bypass valve. There are arrows stamped in the
bypass valve showing flow direction. The arrow pointing toward the valve is the inlet and the
arrow pointing away from the valve is the outlet
1. Apply Teflon tape to the inlet and outlet connectors and install the inlet and outlet con-
nectors in the control valve. Connect the plumbing.
All piping should be secured to prevent stress on the bypass valve and connectors.

weighted strainer. Then drop the strainer in the tank and push the 1/4” tubing through the
hole in the tank until the weighted strainer is about 1” off the bottom of the tank.
4. Now attach the other end of the 1/4” tubing to the pump on the injection panel. Put the nut
over the tubing and then the sleeve. Push the tubing in the pump fitting and tighten the nut
hand tight. The connection on the pump should be held with one hand while the nut is tight-
ened with the other hand. Hand tight should be sufficient.
