parts bag until you are ready to use them.
Unpacking / Inspection
 Check and comply with your provincial / state and
local codes. You must follow these guidelines.
 Use care when handling the water treatment sys-
tem. Do not turn upside down, drop, drag or set on
sharp protrusions.
 The carbon Superfilter system works on 12 volt-60
Hz electrical power only. Be sure to use only the
included transformer.
 Transformer must be plugged into an indoor 120
volt, grounded outlet only.
 WARNING: This system is equipped with a UV
light to remove biological contaminants. Although
this treatment system is in place, US Water Sys-
tems recommends that bacteria levels be checked
periodically to ensure the UV light system is operat-
ing properly. Coliform and E.coli most importantly.

Proper Installation
This water treatment 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 Superfilter Oxi-Gen system provides iron, sulfur and manganese removal
throughout the home. The Fusion Superfilter Oxi-Gen system should be installed at the point of
entry to treat your entire home, both hot and cold water.
The Fusion Superfilter Oxi-Gen system’s backwashing tank removes iron, sulfur and
manganese using oxidation. When water is used in the home, hydrogen peroxide is injected in
the Fusion Superfilter Oxi-Gen feed to create super oxidation during operation. The Catalytic
Carbon media in the Fusion Carbon Superfilter 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 Superfilter Benefits
 Iron, Manganese & 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

The GreenWave Ultra system provides protection from scale formation throughout the home.
The GreenWave system should be installed after the Fusion Oxi-Gen system to treat your
entire home, both hot and cold water, or it can be located directly before a water heater or
other device (e.g. sauna, etc) that requires protection from hard water.
The GreenWave Ultra reduces or eliminates scale formation on internal and external plumbing
surfaces as well as reducing spotting and streaking normally associated with hard water.
The GreenWave Ultra prevents scale by transforming the normal dissolved hardness minerals
into undissolved crystal micro-particles. These crystals stay suspended in the water and
dramatically reduce the scaling potential of hardness minerals. Therefore the problem of
internal build¬up of scale in pipes, water heaters and on fixtures and glass is greatly reduced.
The GreenWave Ultra is not a water softener – Low or phosphate-free cleaning products are
recommended to achieve optimum results. Modern surfactant or detergent based, liquid soaps
are preferred over old-fashioned fashioned caustic solid soaps.
Unlike softened water, the GreenWave Ultra treated water maintains the beneficial essential
mineral content of your water and is safe to drink.
GreenWave Tank Benefits
 Chemical Free Scale Prevention. Cost savings and environmental benefits
 Virtually Maintenance Free. No salt bags or other chemicals to buy, transport and store
 Beneficial minerals retained for more healthful drinking water
 Improves the efficiency of water-using appliances
 Simple installation – no electrical and drain hookup
 Safe for landscaping and lawn watering. No need for costly plumbing bypasses
 Compatible with all on-site and community wastewater treatment systems
 Not subject to water softener restrictions and "bans"

US Water UV Light Introduction
This point-of-use system allows for simple installation and operation due to its high output
lamp and compact reactor. The reactor is an axial flow design with superior hydraulics, com-
pact design and 1” NPT connections. The controller is a simple plug in device connecting to
the lamp with a safety cap.
Water Quality Guidelines
Iron < 0.3 ppm (0.3 mg/L)
Hardness < 7 gpg (120 mg/L)
Turbidity < 1 NTU
Manganese < 0.05 ppm (0.05 mg/L)
Tannins < 0.1 ppm (0.1 mg/L)
UV Transmittance > 85%
The UV light system uses ultraviolet let to kill bacteria and other organics in the water source.
The light from the UV bulb passes through the water and destroys the organic contaminants.
The UV bulb is utilizes a quartz sleeve on the outer portion to isolate the water from the UV
bulb element.
WARNING!
If this quartz sleeve becomes coated or stained it will reduce the light that can pass
through the water in the chamber, thus inhibiting the bacteria removal by the UV light.
It is crucial that the iron, manganese and any tannins in the water are removed prior to
the UV to ensure the light is penetrating the quartz sleeve and its’ full intensity.

Operation
The US Water Systems UV comes with a feature laden controller that incorporates both the lamp driver
(ballast) and control features in one water-tight case. CAUTION: Prior to performing any
maintenance on your UV system, you must always disconnect the power.
USWATER 5.0 & USWATER 6.0 Controller
This controller features a power factor corrected, constant current lamp
driver with a universal power input. A full color LCD screen provides
the user with a detailed description of the system's performance in
addition to providing any applicable fault messages and system
diagnostics. The controllers used in both the USWATER5.0 and USWATER6.0
are identical. The difference is that the USWATER 6.0 series of products
includes a UV intensity monitor. All USWATER 5.0 and USWATER 6.0 controllers
include an "infinite expandability port" located on the right side of the
controller. Simply plug in an optional UV sensor module into the
expandability port of a USWATER 5.0 controller and the system will now
monitor the UV intensity of the system!

7
US Water UV Light Introduction
USWATER 5.0 & USWATER 6.0 Power-up Sequence
Upon start up, the 5.0 & 6.0 controller will run through a diagnostic start-up and the sequence will
be displayed as follows on the color LCD:
Next, the controller checks for the installation of any optional modules that may be installed on the
system. It first checks to see if a module is installed and then either initializes the module to
function with the controller or returns a "not detected" screen and moves on to the next module.
The screens will appear as follows:

Once the controller has finished checking for the installation of all available modules a single screen is dis-
played showing which specific modules are installed and activated on this particular system. Please Note:
If the corresponding module icon is not displayed on this screen, then that module is not installed on this
system. If you believe this module is installed correctly, recheck the applicable connections to ensure a
solid connection point and then restart the controller. The controller then continues to optimize the lamp
efficiency by waiting 60 seconds to allow the lamp to reach its optimum output. Finally, a final "start-up
complete" screen is displayed. These screens will appear as follows:
USWATER 5.0 Operational Screens
On USWATER5.0 systems (without the UV monitor), the default screen shows the US Water Systems Home
Screen. At any point d u rin g operatio n the u ser is able to s cr oll t hro ug h t he US Water Systems
Home Screen, Lamp life remaining and QR Code/Contact Info screens by simply pressing the button
located on the front of the controller.

9
US Water UV Light Introduction
USWATER 6.0 Operational Screens
On systems that have the UV module installed (and on all USWATER6.0 systems), the default screen
shows the % UV Intensity. At any point during operation the user is able to scroll through the % UV
Intensity, Lamp life remaining and QR Code sc reen s b y s im p l y p ress i n g t h e b u tt o n lo cat ed
on the
front of the controller.
USWATER 6.0 % UV Intensity
If your system is equipped with a UV sensor the % UV Output screens will indicate the level of UV intensity
that is being detected within the reactor by the sensor. This will always be visible on the Home Screen of
the controller. Things that can affect the % UV Output are poor water quality, scaling of the quartz
sleeve and/or sensor, lamp failure, expired lamp life and sensor failure. The following screens show the
% UV Output dropping on a monitored system.

10
US Water UV Light Introduction
Once the UV output drops below 56%, the numbers and warning sign switch to red and a 15 second intermit-
tent audible chirp is given off by the ballast. When the output drops below 51%, the display switches to a
solid red and a constant audible signal is provided. The screens alternate between this solid red
screen and another screen indicating "water may be unsafe for consumption". At this point, the controller
also provides a signal to de-activate the solenoid valve, shutting off the flow of water if a solenoid valve is
installed on the system.
USWATER5.0 & USWATER6.0 Lamp Countdown Sequence
The USWATER5.0 & USWATER6.0 counts down the number of days until a lamp change is required. The
operation is as follows:
Once the lamp has seven days remaining until a lamp change is required, the screen changes to a yellow
caution screen. At this point, an audible chirp is given off by the ballast to draw your attention to the
pending lamp change condition. When the controller passes the zero day threshold, the screen chang-
es to solid red and cycles between a red "lamp expired" screen and a "water may be unsafe for consump-
tion" screen. The same intermittent audible chirp is heard throughout this lamp expired sequence.
At any point during this sequence, the audible chirp can be deferred by holding the controller button
down for a period of five seconds. The screen shown below will appear for five seconds indicating that
the audible deferral has been activated and then the system switches back to the cur-
rent lamp change or lamp expired screen. This audible deferral will last for seven
days after which then the alarm will sound once again. This audible deferral feature can
be activated as many times as you wish. PLEASE NOTE: During the condition of lamp
expiration and audible deferral, the water may be unsafe for consumption and should
not be consumed without another form of disinfection.

US Water UV Light Introduction
USWATER5.0 & USWATER6.0 Lamp Countdown Reset Sequence
After changing the lamp on the USWATER5.0 & USWATER.0 systems, the controller must be reset in
order for the system to begin its countdown function on the newly installed lamp. To perform this
reset, you must firmly depress the button on the front of the controller and then manually plug the
power cord back into the wall outlet initiating power to the unit. Keep holding down the button for five sec-
onds until you hear an audible chirp indicating the controller has reset the internal timer.
Release the switch and the lamp countdown feature has now been reset. The following two screens will be
displayed during this process.
USWATER5.0 & USWATER6.0 Failure Modes
The US Water Systems controller continuously monitors your UV system and if there is a problem with the
system the controller will provide both a visual and audible signal indicating the specific fault that may be
adversely affecting the operation of your system. The fault conditions are listed in a priority sequence as
follows:
LAMP FAILURE: If at any tim e d uri ng the op er atio n o f t he
system, the UV lamp fails to be illuminated, the controller will
return both an audible and visual signal indicating lamp failure. In
addition, a constant audible buzzer will sound during lamp failure.
UV SENSOR FAILURE: Assuming the system has a UV Sensor
installed, if at any time during the operation of the system, a UV
sensor fails, the controller will return both an audible and visual
signal indicating sensor failure. For sensor failure, the controller
will cycle between "sensor failure" and "water may be unsafe for con-
sumption" screens as an added precaution. In addition, a con-
stant audible buzzer will sound during sensor failure.

12
US Water UV Light Introduction
SOLENOID MODULE FAILURE: Assuming the system has an o p t io n al So le-
noid Module installed, if at any time during the operation of the system, a
solenoid valve fails to operate, the controller will return both an audible and
visual signal indicating solenoid failure. In addition, an intermittent (15 sec)
audible buzzer will sound during solenoid failure.
4-20 mA MODULE FAILURE: Assuming the system has an opti o n al 4-20 mA
Module installed, if at any time during the operation of the system, a 4-20
mA module fails, the controller will return both an audible and visual signal
indicating a 4-20 mA failure. In addition, an intermittent (15 sec) audible
buzzer will sound during a 4-20 mA failure.
REMOTE ALARM MODULE FAILURE: Assuming the system has an op-
tional Remote Alarm Module installed, if at any time during the operation of
the system, a remote alarm module fails, the controller will return both an
audible and visual signal indicating remote alarm failure. In addition, an in-
termittent (15 sec) audible buzzer will sound during remote alarm failure.
ETHERNET MODULE FAILURE: Assuming the system has an optional Ethernet
Alarm Module installed, if at any time during the operation of the system, an
Ethernet module fails, the controller will return both an audible and visual
signal indicating Ethernet failure. In addition, an intermittent (15 sec) audi-
ble buzzer will sound during Ethernet failure.
USWATER 5.0 & USWATER 6.0 QR Codes
A QR code (abbreviated from Quick Response code) is a type of matrix barcode (or two -dimensional
code) first designed for the automotive industry. US Water Systems uses the QR code to store a link to a
specific page on our website. Users with a camera phone equipped with the correct reader application
can scan the image of the QR code and over a wireless network connect to a US Water Systems web page
in the phone's browser. US Water Systems' QR webpage has information on how to purchase replacement
components as well as a helpful video directory on system servicing
(i.e. How to change a UV lamp or quartz sleeve). To access the QR code on the USWATER5.0 or
USWATER6.0 controller simply press the control button twice and the QR code screen will appear as
follows:

US Water has pioneered the use of hydrogen peroxide in water treatment for the eradication of
iron (rust), sulfur (hydrogen sulfide odor) and manganese for nearly 20 years. It can truly be
called an "Eradication System" because it TOTALLY removes iron, sulfur and manganese.
Properly sized, an Fusion Superfilter Oxi-Gen Hydrogen Peroxide System from US WATER is
THE MOST EFFECTIVE METHOD for removing iron, rust, sulfur, manganese and hydrogen
sulfide (the rotten-egg odor) from your water supply. The Fusion Superfilter 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, manganese
and hydrogen sulfide) is immediate. The Fusion Superfilter Oxi-Gen Hydrogen Peroxide
System is the answer to practically any iron, rust, sulfur, hydrogen sulfide or manganese
problem, and is backed with our 90-Day 100% Satisfaction Guarantee. US Water Systems
guarantees 100% iron, manganese and sulfur removal with its Fusion Superfilter 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.
Consider the H2O2 advantages and you’ll know
why this is the ONLY sure way to eradicate iron,
manganese 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, sulfur and manganese. 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, SULFUR
OR MANGANESE – ALL THE TIME – GUARANTEED!

The Fusion Superfilter Oxi-Gen iron, sulfur and manganese eradication system uses Hydrogen
Peroxide (H2O2) to oxidize contaminants in your water source. The chemical name for
hydrogen peroxide is H2O2. As you can see 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, sulfur and
manganese 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, sulfur and manganese free! Extreme levels of manganese may require a
water softener in addition to the Fusion Superfilter 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.

The Importance of Contaminant Removal Prior to the GreenWave Tank
Iron and Manganese
Just as with conventional water softening media, the GreenWave media needs to be protected
from excess levels of certain metals that can easily coat the active surface, reducing its
effectiveness over time. Public water supplies rarely, present a problem, but if the water supply is
from a private well confirm that the levels of iron (Fe) and manganese (Mn) are less than 0.3 mg/L
and 0.05 mg/L respectively. Copper should be less than 1.3 mg/L.
Copper
Copper usually originates from new copper plumbing upstream of the GreenWave Ultra system. If
this condition exists, we recommend waiting 3-4 weeks before placing the system in operation. This
will allow the copper surfaces to be fully flushed and develop a natural protective surface. To
further minimize any problem with excess copper the installers should be advised to avoid applying
excess flux on the inner surfaces of the pipe and to use a low-corrosivity water soluble flux listed
under the ASTM 8813 standard. Once the plumbing connections are complete, place the
GreenWave Ultra system in bypass prior to following the startup procedure and flush the plumbing
for at least 10 minutes.
Cautions!
 Do not let the system freeze. Damage to the tank and pre-filter may result.
 The system must be operated in a vertical position. Do not lay it down during operation. The
system may be placed in any position for shipping and installation but must be operated in the
vertical position.
 Place the system on a smooth, level surface. Because the system operates in an UP-Flow,
fluidized bed mode, having a level surface is more important than with a softener or media filter.
 A bypass valve should be installed on every system to facilitate installation and service
(supplied).
 Observe all local plumbing and building codes when installing the system.
Notes to the Installer
The GreenWave Ultra system differs from a conventional softener or media filter in a number of key
respects.
 The system is light and only partially filled with media. This is normal. The UP-flow operation of
the system requires a large area of freeboard in the tank to allow the bed to fully fluidize.
 The GreenWave tank has no under-bed so you can tip the system over without any fear of
upsetting the media. This makes transportation and installation much easier than conventional
systems. The carbon Superfilter does have under-bedding and should not be moved once
filled.
 Because the GreenWave Ultra system operates in the UP-Flow mode, the tank connections are
opposite of what a normal softener will use.
 Please see the "important note about iron, manganese and copper" above.

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 your voltage supply is
compatible with your 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 SUPERFILTER TANK AND DRAIN: The Fusion Superfilter
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 Superfilter 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. If possible, fill the car-
bon tank with water and allow it to soak while the other components are installed. This
will reduce the backwash/ rinse time needed to flush out the carbon fines during the
startup procedure.

2. Lubricate the distributor O-ring and the tank O-ring. Then install the upper basket (may
look different than the pictures 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. Move the carbon unit to the side and start the injection panel installa-
