INSTALLATION INSTRUCTIONS
Proper operation of this equipment is dependent on an installation that conforms to the manufacturers instructions and
follows local plumbing and electrical codes. Meeting the following requirements will assure long, reliable product operation.
INSTALLATION REQUIREMENTS
• Select a heated installation location that has sufcient oor space and headroom to provide access for ease of
installation and servicing. Refer to the Specication Table for dimensional data. Ambient temperature must never
drop below 40 degrees F. to protect from freezing. Maximum water temperature + 110 Degrees F.
• Locate Filter System piping as close as possible to the source of the building water supply. The ideal location is after
the pressure tank and all outside water taps and prior to an existing water softener. Never install between the water
pump and pressure tank or on an intermittent water pressure source.
NOTE: This system is not designed for irrigation purposes.
• A grounded uninterrupted electrical power source (115 volts, 60 Hertz, I Ampere) is required to operate the fully
automatic controls.
• An adequately sized oor drain, dry well or sump pit is required to collect wastewater during recharge of the Filter
System. Refer to Specication Table for Backwash ow rate. The wastewater is harmless but can stain surfaces it
comes in contact with.
• The Control Valve, Bypass and installation ttings are designed to accommodate minor plumbing misalignments.
Components are not designed to support the weight of the Filter Vessel or the plumbing system.
• Soldering of plumbing ttings must be performed away from plastic valve components.

FILTER VESSEL PREPARATION
1. Remove Filter Vessel from shipping carton. Carefully unscrew the Control Valve mounted on top of the Tank. Set
the Valve aside. The Riser Pipe in Filter Vessel should be 1” above the top of the Vessel.
2. Place Filter Vessel (Tank #2) at installation location. Temporarily install plastic cap onto top of Riser Pipe.
3. Pour gravel from bag labeled Ll for Tank #2 into Filter Vessel. A funnel is provided for convenience.
4. Pour coarse Garnet from bag labeled L2 for Tank #2 into the Filter Vessel.
5. Pour ne Garnet from bag labeled L3 for Tank #2 into the Filter Vessel.
6. Pour Greensand from bag labeled L4 for Tank #2 into the Filter Vessel.
7. Pour Anthracite from bag labeled L5 for Tank #2 into the Filter Vessel. Remove funnel.
8. Wipe dust from threads of Tank and Riser Pipe. Remove the plastic cap from Riser Pipe opening.
9. Lubricate both O-Rings on the base of the Filter Control Valve. Install the Filter Control Valve into the Tank threads by
turning clockwise until the control valve is tight.
PLUMBING CONNECTIONS
Both Control Valves are equipped with a By-Pass Valve eliminating the need for manual isolation valves.
1. Select a point in the building plumbing after irrigation branches and before an existing water softener. Connect the
Inlet port of the Oxidizer Vessel Valve to the pressurized water source at that point (see diagram on page 1 of this manual).
2. Connect the Outlet port of the Oxidizer Valve to the Inlet port of the Filter Valve.
3. Connect the Outlet port of the Filter Valve to the treated water piping of the building.
4. Both Valves require a connection to drain. Local plumbing codes will require an air gap to prevent sewage backup into the
Filter System. Rigid tubing or pipe is recommended. IMPORTANT: Pressurized air and water is released during
recharge. The end of the drain piping must be secured and positioned to prevent movement and splashing. Drain lines
should not exceed 5 ft. above the top of the valve or 25 ft. in length.
IMPORTANT: Do not apply water pressure to the Filter System at this time. Position the handles on both By-Pass Valves to
the By-Pass positions (arrows should be pointing at each other).
ELECTRICAL CONNECTIONS
1. Both Valves require connection to a continuous source of electrical power. Do not plug in control valves in at this time!
2. Filter System installations into metallic plumbing (copper tubing or galvanized pipe) requires a grounding strap. Connect
length of 12 Gauge wire between the inlet pipe of the Oxidizer Valve and the outlet pipe of the Filter Valve. Strap the
bared ends of the copper wire to the cleaned outside surface of the metal pipe. Route the wire carefully to prevent
breakage. Installations into plastic plumbing do not require the grounding strap.
START-UP PROCEDURES
NOTE: DO NOT PLUG THE CONTROL VALVES INTO AN ELECTRICAL OUTLET UNTIL INSTRUCTED TO DO SO.
1. Make sure both units are in the bypass position.
2. Close all valves that are open.
3. If you have a water softener installed make sure it is bypassed.
4. Turn on the main water supply. Turn water on at the closest cold water tap. Allow water to run until all excess air has
been relieved and water runs clear.
5. Close faucet.
OXIDIZER START-UP
6. Open the inlet valve a 1/4 turn to allow water to enter the oxidizing lter. The control valve is shipped in the Fast Rinse
cycle. This allows water to run to the drain. Once water is running to the drain slowly, open the inlet completely.
7. Let water run to drain for 10 minutes or until water runs clear.
8. Remove cover and plug the four prong adaptor into the circuit board. Replace cover for the oxidation tank.
9. Plug the transformer for the oxidation tank into a 120V electrical outlet and allow control to cycle to the Home position.
10. Open outlet valve and slowly open inlet valve on ltration tank.
11. Allow ltration tank to ll with water.
12. Open outlet valve on ltration tank.
13. Open a treated water faucet and allow excess air to escape. When water runs clear, turn faucet off.
14. Do not initiate a regeneration.
15. Plug ltration unit into a wall receptacle.
16. Do not initiate a regeneration.

17. The unit must sit for 24 to 48 hours before a complete regeneration should occur. This gives the media time to
saturate. Insufcient saturation time will cause media to be lost to drain. FAILURE TO FOLLOW PROPER
START-UP INSTRUCTIONS WILL RESULT IN EQUIPMENT MALFUNCTION NOT COVERED
UNDER WARRANTY.
20. Open the nearest cold water faucet.
21. Allow water to run until clear and excess air has been purged from the line.
22. Close faucet.
23. If you have placed the water softener in bypass, return the softener to the Service position.
24. Open shut off valve to the water heater.
25. Verify the regeneration times. See step 1 below.
26. Set time of day. See page 5 & 6.
BACKWASHING
The Filter Vessel (Tank #2) must independently Backwash prior to the Oxidizer Vessel (Tank #1). It is
important to stagger the Backwash start time for each Vessel. If there is a water softener system present, it is
important to not only schedule staggered backwashing times of the lters, but also at different times than the softener’s
scheduled backwashing time. The Klear-Flo II units are preset to have staggered backwash times. These backwash times
are recommended because most water residential water supplies do not produce sufcient ow and pressure to backwash
both Vessels simultaneously.
1. FILTER VESSEL SETTINGS - Follow the procedure below to set the lter vessel regeneration time & frequency.
A. On the lter vessel, press the NEXT and UP arrow keys simultaniously for three to ve seconds. The screen
will show -nA-. Press the NEXT key.
B. The lter comes pre-programmed for 3 days. Changes can be made later if different backwash cycle intervals
are required.
C. Once days between regeneration has been selected press the NEXT key.
D. Time of Regeneration screen. The unit comes preset at 1 AM. To change the time, use the UP or DOWN arrow
keys. Make sure to note AM or PM. Press NEXT to set minutes. Press NEXT to return to home screen.
2. OXIDIZER VESSEL SETTINGS - Follow the procedure below to set the oxidizer vessel:
A. On the oxidizer vessel, press the NEXT and UP arrow keys simultaniously for three to ve seconds. The
screen will show -nA-. Press the NEXT key.
B. Set the Days to Regenerate. The Oxidizer Vessel is capable of treating 1,000 gallons per
regeneration. Daily water usage will determine the regeneration frequency. Select one
recommended regeneration schedule from the following table:
• Recharge every 3 days - ( 1-2 people per family or 200 gallon/day water usage)
• Recharge every 2 days - (3-4 people per family or 400 gallon/day water usage)
• Recharge every day - (5 or more people per family or 1000 gallon/day water usage.)
Changes can be made later if different Backwash cycle intervals are required.
C. Once days between regeneration has been selected press the NEXT key.
D. Time of Regeneration screen. The unit comes preset at 12 AM. To change the time, use the UP or DOWN
arrow keys. Make sure to note AM or PM. Press NEXT to set minutes. Press NEXT to return to home screen.
IMPORTANT: UNITS ARE PRE-PROGRAMMED TO HAVE STAGGERED BACKWASH TIMES. IF YOU CHOOSE TO
RE-PROGRAM, PLEASE REMEMBER TO SET STAGGERED BACKWASH TIMES.
WATER SOFTENER NOTE: The Klear-Flo Filter System is compatible with most automatic Water Softeners. The
Softener will performn best when installed after the Klear-Flo Filter System. The regeneration schedule of the
water softener must be set to start 3 hours before or 2 hours after the Klear-Flo start time. This will assure that
sufcient water volume and drain capacity is available for the regeneration process of each unit.

User Display Settings
When the system is operating, several displays may be shown.
Pressing NEXT will alternate between the displays. One of the
displays is the current time of day. CAPACITY REMAINING
is the gallons that will be treated before the system goes through
a regeneration cycle. Pressing DOWN while in the Capacity
Remaining display will decrease the capacity remaining in
10 gallon increments and will also increase the volume used
impacting the recorded values in Diagnostics.
DAYS TO A REGEN is the number of days left before the system
goes through a regeneration cycle. Pressing UP or DOWN while in
this screen will temporarily increase or decrease the displayed value by
1 day. Another display shows the current treated water flow rate through
the system. Contact information will be displayed if it was edited.
The fifth display will show either DP or HOLD if
the dP switch is closed. If the system has called for a
regeneration that will occur at the pre-set time of regeneration,
the words REGEN TODAY will alternate with the header on the
display. If a water meter is installed, GPM flashes (and alternates
with the flow rate) on the display when water is being treated (i.e.
water is flowing through the system).
GPM and flow rate
will flash while water
is being treated.
Set Time of Day
The user can also set the time of day. Time of day should only need to be set if the battery has been depleted because of extended
power outages or when daylight saving time begins or ends. If an extended power outage occurs, the time of day will flash on and
off which indicates the time of day should be reset. The non rechargeable battery should also be replaced.
Regeneration Mode
Typically a system is set to regenerate at a time of low water usage. An example of a time with
low water usage is when a household is asleep. If there is a demand for water when the system is
regenerating, untreated water will be used.
When the system begins to regenerate, the display will change to include information about the step of the regeneration
process and the time remaining for that step to be completed. The system runs through the steps automatically and will reset
itself to provide treated water when the regeneration has been completed.
Manual Regeneration
Sometimes there is a need to regenerate the system sooner than when the
system calls for it, usually referred to as manual regeneration. There may
be a period of heavy water usage because
of guests or a heavy laundry day.
To initiate a manual regeneration at the preset delayed regeneration time, when the regeneration time option is set to
“DELAYED REGEN” or “DELAY + IMMEDIATE”, press and release “REGEN”. The words “REGEN TODAY” will
periodically be shown on the display to indicate that the system will regenerate at the preset delayed regeneration time. If you
pressed the “REGEN” button in error, pressing the button again will cancel the request. Note: If the regeneration time option
is set to “IMMEDIATE” there is no set delayed regeneration time so “REGEN TODAY” will not activate if “REGEN” button
is pressed.
To initiate a manual regeneration immediately, press and hold the “REGEN” button for three seconds. The system will begin
to regenerate immediately. The request cannot be cancelled.
Note: For softeners, if brine tank does not contain salt, Fill with salt and wait at least two hours before regenerating.

PRINCIPLE OF OPERATION
The Klear-Flo II uses a four-step process called Oxidation/Filtration to reduce the levels of iron, manganese and hydrogen
sulde gas from potable water without the need for retention tanks, chemicals, air compressors and re-pressurizing pumps.
The system is comprised of two vessels and controls connected in series. The rst being the Oxidizer Vessel and the second
being the Filter Vessel. The Oxidation/Filtration process modies the characteristics of the water owing through the vessels.
The individual steps are described in their order of occurrence:
1. Oxygen Enrichment - Flowing water and air are combined under pressure. The owing water takes on a higher
concentration of air similar to carbonating a beverage. This step occurs in the top of the Oxidizer Vessel.
2. Acidity Reduction - The corrosive effects of aggressive water is reduced. As a result, metallic components of the
plumbing system will be protected from corrosion. The reduced acidity also promotes a rapid reaction between the
oxygen introduced in Step # 1 and owing water to promote Precipitation. This step occurs in the bottom of the
Oxidizer Vessel.
3. Precipitation - The oxygen component of the air reacts with dissolved compounds of iron, manganese and sulde in
the owing water. The oxygen safely breaks the dissolved compounds down into a harmless particulate state that is
readily removed by Filtration. This step occurs in the top of the Filter Vessel.
4. Filtration - Particles (oxides) of iron, manganese and suldes are removed from owing water. Multiple layers of granular
media trap the oxides passing only clear, odorless, stain free water. This step occurs in the bottom of the Filter Vessel.
The Oxidation/Filtration process silently treats water on demand over a wide range of ows. During operation, the com-
pressed air charge in the Oxidizer Vessel enriches the water with air containing Oxygen. The Oxygen provides the chemical
energy needed to produce iron, manganese and sulfur oxides. The newly formed precipitated oxides are trapped in the Filter
Vessel as water is treated. The treated water exits the lter with an excess of dissolved air causing a cloudy (milky) appear-
ance when rst dispensed. Upon standing the water clears as the excess air escapes.
Eventually the compressed air charge depletes and the Oxidizer Filter is lled to capacity with oxides. A charge sequence
is required to both replenish the air and remove the ltered oxides. The system is fully automatic and self recharges on an
adjustable, programmed time schedule. The amount of ltered water delivered is dependent on the amount of contaminants
in the water and the frequency of recharges.

RECHARGE SEQUENCE
The Klear-Flo II lter system is comprised of two individual pressure vessels each having plumbing connections providing a
means for installation into a continuously pressurized water system. The vessels are installed in series with the Oxidizer Ves-
sel positioned ahead of the Filter Vessel. A demand for treated water causes ow to occur through both vessels. Raw water
entering the lter is rst oxygenated then ltered. This cycle of operation is referred to as SERVICE. Eventually the lter
system requires a recharge of oxygen and a thorough cleaning of the ltration media. This multi step process is referred to
as the RECHARGE SEQUENCE.
Each vessel is individually recharged in succession during a time period when treated water demand is low. The recom-
mended times for recharge are AM for the Oxidizer Vessel and AM for the Filter Vessel. The time intervals must be staggered
so each vessel has access to an adequate water supply. Each vessel is equipped with an adjustable calendar clock control-
ler capable of initiating the recharge sequence at a user-deterrnined schedule. (Refer to Determining a Recharge Schedule)
The following is a description of each step in the RECHARGE SEQUENCE.
The Oxidizer Vessel is sequenced rst (Steps # 1 - 4) followed by the Filter Vessel (Steps # 5 - 7). Water pressure and ow is
available during all steps of the RECHARGE SEQUENCE, however the water quality may be unsatisfactory during this time
interval.
1. FLUSH #1 - Raw water is by-passed directly to the Filter Vessel. The Oxidizer Vessel is repressurized with water
compressing the new air charge. The down ow of water is directed to the bottom of the vessel and discharged to
drain. The compressed air remains at the top of the Vessel.
2. BACKWASH #1 - Raw water is by-passed directly to the Filter Vessel and is also directed into the bottom of the
Oxidizer Vessel. The top of the Oxidizer Vessel is vented to atmosphere and routed to a drain. The remaining air
charge is released. Simultaneously the trapped particles in the pH neutralizing granular lter media are removed by
a reverse ow of water and discharged to the drain.
3. AIR INJECTION - Raw water is by-passed directly to the Filter Vessel. All water is removed from the Oxidizer Vessel
and replaced with a fresh supply of air at atmospheric pressure. This process is accomplished with a venturi. There
will be a low ow of water to the drain.
4. OXIDIZER RETURN TO SERVICE - Oxygenated, pH neutral, ltered water is available for the recharge of the Filter
Vessel. There will not be a ow to the drain.
5. BACKWASH #2 - Oxygenated, pH neutral, partially ltered water is by-passed directly to the Filter outlet and is
also directed into the bottom of the Filter Vessel. The top of the Filter Vessel is vented to atmosphere and routed to a
drain. Trapped particles in the granular lter media are removed by a reverse ow of water and discharged to the
drain.
6. FLUSH #2 - Oxygenated, pH neutral, partially ltered water is by-passed directly to the Filter outlet.The down ow of
water is directed to the bottom of the vessel and discharged to drain. Remaining particles are ushed from
both Vessels.
7. SYSTEM RETURN TO SERVICE - Oxygenated, pH neutral, odor free, ltered water is available at the Filter System
outlet. There will not be a ow to the drain.
