The Chem-Free Iron Filter consists of three
major components which are: Control Valve,
Air Tank, Media Tank. Natural oxidation re-
moves iron, sulfur and manganese without
chemicals, air pumps or a venturi.
Incoming raw water passes through a pocket
of air in the first tank. The oxygen in the air
oxidizes the iron into a solid form and it re-
moved when it passes through the second
filter tank. The media in the second filter
tank acts as a catalyst in the reaction be-
tween the iron and oxygen that causes the
iron to precipitate into a solid so it can be fil-
tered out of the water.
As more water passes through the unit, the
air becomes depleted in the first tank and the
filter media in the second tank becomes over
loaded with iron. A periodic automatic re-
generation replenishes a supply of air and
cleans the iron out of the filter tank.
There are no chemicals used for this system
to work. The filter media automatically ad-
justs the pH to neutral or higher on acid wa-
ter without an acid neutralizer. The ability to
raise pH when it is below neutral (7 or less)
greatly enhances the filter’s ability to remove
iron efficiently. The clean, filtered water then
flows into your household water line. De-
pending on water use and the concentration
of iron in your water, periodic backwashing is
required to flush the entrapped iron from the
system. The system can be set to regenerate
as clock every 1 – 99 days or as meter de-
layed based on gallons between regenera-
tions.
Your filter is factory set to backwash at 12:00
a.m. during a period of little or no water use.
The automatic regeneration cycle lasts ap-
proximately 60 minutes, after which filtered
water service is restored. While backwashing
is taking place raw water automatically by-
passes the filter if required. If possible, avoid
using water during backwashing to prevent
iron-laden water entering your household
plumbing system.
IRON (Fe)
Iron concentrations as low as 0.3 ppm will
cause staining. The iron concentration, to-
gether with the flow rate demand and the
consumption rate of the water determines
the basic size filter system. The higher these
factors are, the larger the required system.
The filter system is capable of filtering out
the three main types of iron found in water
supplies: Soluble iron (also known as “clear
water” or ferrous iron), precipitated iron (also
known as “red water” or ferric iron) and bac-
terial iron (also known as iron bacteria).
There is no apparent upper limit of iron con-
centration for the filter, but special care must
be taken when selecting a filter model if your
water has a combination of high iron, very
low pH and/or manganese.
MANGANESE (Mn)
The presence of manganese can be bother-
some, even for a chemical free iron filter. As
little as 0.05 ppm of manganese can produce
a brownish or black stain. The ability of the
filter to remove manganese depends on its
concentration and the pH of the water.
Manganese tends to “coat” the filter media,
rendering it incapable of increasing the pH,
and therefore ineffective in removing either
the iron or the manganese. Manganese, how-
ever, will precipitate in the filter bed when
the pH is increased. To accomplish this a spe-
cial “MN” type media can be provided that
contains additional quantities of the pH rais-
ing component (“MN adder”). The use of
“MN” type media is for applications where
the manganese is not more than 1.5 ppm,
and the pH is at least 6.5.
How The System Works
5

Before Starting Installation
Tools, Pipe, and Fittings, Other Materials
 Pliers
 Screwdriver
 Teflon tape
 Razor knife
 Two adjustable wrenches
 Additional tools may be required if modifi-
cation to home plumbing is required.
 Plastic inlet and outlet fittings are included
with the filter. To maintain full valve flow,
3/4” or 1” pipes to and from the filter fit-
tings are recommended. You should main-
tain the same, or larger, pipe size as the
water supply pipe, up to the filter inlet and
outlet.
 Use copper, brass, or PEX pipe and fittings.
 Some codes may also allow PVC plastic
pipe.
 ALWAYS install the included bypass valve,
or 3 shut-off valves. Bypass valves let you
turn off water to the filter for repairs if
needed, but still have water in the house
pipes.
 5/8” OD drain line is needed for the valve
drain. A 10’ length of hose is included.
with some models.
pH
The pH of water measures its acidity or its
alkalinity. Water with a pH of less than 7.0 is
acidic, above 7.0 it is alkaline, and a pH of
7.0 is neutral. The lower the pH value is be-
low 7.0 the greater the acidity, and the
higher the pH value is above 7.0 the more
alkaline. Acidic water (pH less than 7.0) is
corrosive to pipes, appliances, etc. A pH of
7.0 or higher facilitates iron removal — which
is why the filter is designed to increase the
pH when it is less than 7.0.
TANNINS (Humic Acid)
Tannins (also known as humic acid) which
are present in some water supplies, are the
result of decaying vegetable matter. If the
tannin concentration is above approximately
0.5 ppm, it will form a sticky coating on the
media, thus rendering it incapable of filtering
the iron. A chemical free iron filter is not rec-
ommended under this condition. If the tannin
concentration is less than 0.5 ppm, a chemi-
cal free iron filter may be installed.
HYDROGEN SULFIDE (H2S)
Hydrogen sulphide (often referred to as
“sulphur”), is easily detectable by its objec-
tionable “rotten egg” odour. Sulphur corrodes
iron, brass, copper and silver. A chemical free
iron filter is capable of removing sulphur in
concentrations of up to 3 to 5 ppm. When-
ever hydrogen sulphide is present, backwash-
ing must be performed at more frequent in-
tervals.

 Place the filter tank as close as possible to
the pressure tank (well system) or water
meter (city water).
 Place the filter tank as close as possible to
a floor drain, or other acceptable drain
point (laundry tub, sump, standpipe, etc.).
 Connect the filter to the main water supply
pipe BEFORE the water heater. DO NOT
RUN HOT WATER THROUGH THE FIL-
TER. Temperature of water passing
through the filter must be less than 100
deg. F.
 Keep outside faucets on hard water to
save soft water and salt.
 Do not install the filter in a place where it
could freeze. Damage caused by freez-
ing is not covered by the warranty.
 Put the filter in a place water damage is
least likely to occur if a leak develops. The
manufacturer will not repair or pay for wa-
ter damage.
 A 120 volt electric outlet, to plug the in-
cluded transformer into, is needed within 6
feet of the filter. The transformer has an
attached 6 foot power cable. Be sure the
electric outlet and transformer are in
an inside location, to protect from
wet weather.
 If installing in an outside location, you
must take the steps necessary to assure
the filter, installation plumbing, wiring,
etc., are as well protected from the ele-
ments, contamination, vandalism, etc., as
when installed indoors.
 Keep the filter out of direct sunlight.
The sun’s heat may soften and distort
plastic parts.
Where To Install The Filter
7

Sizing Requirements
This unit is factory set for backwash every 4 days. More frequent backwash may be re-
quired based on water conditions and amount of water used.
Water Pressure
The water system must have a pump big enough to deliver the recommended backwash
rate with a minimum pressure at the inlet of the filter of 30 psi. If the existing system can-
not do this, it must be upgraded to do so. Whenever possible, the water system should be
adjusted to deliver at least 30 psi for even more satisfactory results.
Backwash Flow Rates
The most important criteria in sizing an iron filter is the capacity of the pump. The water
must pass through the filter media at a service flow rate that allows it to oxidize and collect
the iron. The filter must also be backwashed at a flow rate sufficient to dislodge and remove
the captured iron. Failure to provide sufficient water will cause a build-up of iron in the filter
media, impairing its iron removing ability and resulting in iron bleeding out into the service
water. In order for your filter to backwash and rinse properly, your pump must be capable of
providing the backwash flow rates indicated on page 4.
Check Your Pumping Rate
Two water system conditions must be checked carefully to avoid unsatisfactory operation or
equipment damage:
1. Minimum water pressure required at the filter tank inlet is 20 psi.
2. Measuring the pumping rate of your pump:
With the pressure tank full, draw water into a container of known volume, and measure the
number of gallons drawn until the pump starts again. This is draw-down. Divide this figure
by cycle time and multiply the result by 60 to arrive at the pumping rate in gallons per min-
ute (gpm). To aid in your calculation, insert the date in the following formula:
DRAW-DOWN ______ ÷ CYCLE TIME _______ x 60 = PUMPING RATE ________ (gals)
(secs.) (Gpm)
EXAMPLE: CYCLE TIME is 53 seconds. DRAW-DOWN is 6 gallons; then, PUMPING
RATE equals:
6 gallons ÷ 53 seconds x 60 = 6.8 gpm
See chart on page 3 for minimum flow rates.
NOTE: If your pumping rate is inadequate for the model, do not install your filter until
the problem has been corrected.
Backwash Frequency
8

1. Locate the Air and Media Tank close to a drain where the system will be installed. The
surface should be clean and level.
2. Shut off all water at main supply. On a private well system, turn off power to pump and
drain pressure tank. Make certain pressure is relieved from complete system by opening
nearest faucet to drain the system. Shut off fuel supply to water heater.
3. Cut the main supply line as required to fit plumbing to the control valve with bypass.
4. Solder or solvent weld plumbing. Do not apply heat to any fitting connected to the control
valve as damage may result to the internal parts. Check to be certain water supply pipe is
connected to the control valve inlet fitting and pipe connected to control valve outlet fit-
ting is in direction of house service.
5. Perform all plumbing according to local plumbing codes. Use a ½” minimum pipe or tub-
ing size for the drain line. Use a ¾” pipe or tubing for backwash flow rates that exceed 7
gpm or length that exceeds 20ft (6 m). NOTE: ON COPPER PLUMBING SYSTEMS BE
SURE TO INSTALL A GROUNDING WIRE BETWEEN THE INLET AND OUTLET
PIPING TO MAINTAIN GROUNDING.
6. Any solder joints near the valve must be done before connecting any piping to the valve.
Always leave at least 6" (152 mm) between the valve and joints when soldering pipes
that are connected to the valve. Failure to do this could cause damage to the valve.
7. Install ¾” check valve on inlet of bypass valve.
8. Connect the drain line to the valve.
9. Place unit in the bypass position.
10.Slowly turn on the main water supply.
11.At the nearest cold treated water tap nearby remove the faucet screen, open the faucet
and let water run a few minutes or until the system is free of any air or foreign material
resulting from the plumbing work. Close the water tap when water runs clean.

Plumbing System Clean-Up
The following procedures are guidelines only
but have proven successful in most in-
stances. Under no circumstances should any
procedure outlined below be followed if con-
trary to the appliance manufacturer's instruc-
tions. Should there be any questions con-
cerning the advisability of performing a pro-
cedure, it is strongly recommended the
manufacturer's authorized service outlet be
consulted prior to performing the procedure.
The plumbing system and water using appli-
ances that have been exposed, even for a
short time, to iron-fouled water need to be
cleaned of the precipitated iron that has col-
lected in them or iron bleed (staining) will
continue to be a problem.
Depending on the amount of iron in the wa-
ter and the length of time the water system
has been exposed to iron fouling, select from
the following procedures those that apply to
the type of system and appliances that need
to be cleaned to assure iron-free water at all
points of use.
It isn't uncommon that the softener was in-
stalled in an effort to remove ferrous (clear
water) iron from the water supply. Typically a
softener will remove some ferrous iron until
the resin bed becomes fouled to the extent
that it will lose both hardness removal capac-
ity and the limited capacity for iron removal.
This is the condition to expect the softener to
be in when planning a system clean-up. Prior
to closing the main supply valve or turning
power off to a private well system and pre-
paratory to installing the filter system, do the
following:
1. Disconnect the brine draw line from the
brine cabinet and place the loose end into
a five gallon plastic pail filled with a solu-
tion of warm water and 4 oz. of resin min-
eral cleaner.
2. Advance the control timer to the brine
draw position (refer to instructions pro-
vided with your softener). Allow all the
warm mineral cleaner solution to be drawn
into the mineral bed.
3. Then immediately close the main water
supply valve or turn the power off to the
pump and proceed with the filter installa-
tion. During the time required to install the
filter system, the iron-fouled softener resin
will be chemically cleaned.
4. After the filter installation is completed and
final adjustments have been made, with
the water turned on and the brine draw
tube reconnected, reposition the timer on
the softener to the backwash position. Al-
low the timer to perform an automatic re-
generation cycle. During backwash of the
softener, all iron cleaned from the resin
will be washed down the drain. It is advis-
able, after chemically cleaning the sof-
tener, to regenerate the system twice to
fully restore capacity lost due to iron-
fouling.
Softener
11

If the water heater has been exposed to both
iron and hardness for a long period of time,
replacement of the heater tank may be the
only practical solution to prevent continued
staining originating from this source. After
completing the installation of the chemical
free iron filter, clean the water heater by fol-
lowing these instructions:
1. Shut off the energy supply to the water
heater and close the heater inlet water
valve.
2. Drain hot water tank completely. Open
inlet water valve, allowing heater tank to
be refilled with iron-free water. Continue
flushing until the water runs clear to the
drain.
3. If, after approximately 30 minutes of flush-
ing, water does not clear, terminate the
flushing operation. Refill hot water heater
with water and pour approximately 1/2
gallon of household bleach into the top of
the heater tank. Allow bleach solution to
stand in tank for 20 to 30 minutes. Flush
the tank again until water is clear at the
drain. Turn energy supply on.
NOTE: If water does not clear in approxi-
mately 10 minutes, water heater should
probably be replaced.

About The System
Manual Regeneration (Step / Cycle Valve)
To Initiate the manual regeneration, rotate the knob to the backwash position.
Operation During A Power Failure
In the event of a power failure, the valve will keep track of the time and day for 48 hours.
The programmed settings are stored in a non-volatile memory and will not be lost during a
power failure. If power fails while the unit is in regeneration, the valve will finish regenera-
tion from the point it is at once power is restored. If the valve misses a scheduled regen-
eration due to a power failure, it will queue a regeneration at the next regeneration time
once power is restored.
Main Display
When power is supplied to the control, the screen will display TIME OF DAY, GALLONS RE-
MAINING, and DEALER NAME and PHONE NUMBER.
The brine tank is equipped with a safety float which prevents your brine tank from overfill-
ing as a result of a malfunction such as a power failure.
Safety Float
New Sounds
You may notice new sounds as your water softener operates. The regeneration cycle lasts
up to 180 minutes. During this time, you may hear water running intermittently to the drain.
13

Automatic Raw Water Bypass During Regeneration
The regeneration cycle can last 80 minutes after which filtered water service will be re-
stored. During regeneration, un-filtered water is automatically bypassed for use in the
household. Hot water should be used as little as possible during this time to prevent un-
filtered water from filling the water heater. This is why automatic regeneration is set for
sometime during the night and manual regenerations should be performed when little or no
water will be used in the household.
Normal regeneration time is 12:00 AM.
Periodically the filter will require a back wash to clean the trapped particles, unpack the fil-
ter bed to restore the system flow rates, and replenish the air in the contact tank.. The ta-
ble below explains the regeneration steps.
Regeneration Process
Manual Bypass

In the case of emergency you can isolate your water filter from the water supply using the
bypass valve located at the back of the control. In normal operation the bypass is open with
the on/off knobs in line with the inlet and outlet pipes.
To isolate the filter, simply rotate the knobs clockwise (as indicated by the word BYPASS
and arrow) until they lock. You can use your water related fixtures and appliances as the
water supply is bypassing the filter. However, the water you use will be hard. To resume
water service, open bypass valve by rotating the knobs counterclockwise.

Maintenance
Care of Your System
To retain the attractive appearance of your new water softener, clean occasionally with mild
soap solution. Do not use abrasive cleaners, ammonia or solvents. Never subject your sof-
tener to freezing or to temperatures above 100°F.
Maintenance of your new water filter requires very little time or effort but it is essential.
Regular maintenance will ensure many years of efficient and trouble-free operation.
1. Periodically make sure your pump is performing satisfactorily to ensure sufficient water
is available for backwashing the filter.
2. Periodically test your raw and filtered water to ensure conditions are still the same for
your original settings and that the unit is working they way it is intended to. Water
testing is often the best way to determine when the filter media will require replace-
ment.
3. Periodically check that the drain line is clear and free from any obstructions.
Check to ensure all media parts are received.
The first step in replacing the media bed is to shut off the water supply to the filter. Then
place the unit into the backwash position to release any pressure in the lines. At this point,
you must disconnect the plumbing from the inlet and outlet. Then unscrew the control
valve from the fibreglass tank. Once this has been done, remove the distributor tube. Then
you can remove the filter media and two types of gravel from the tank. The quickest way to
do this is by simply tipping the tank upside down into a large drum or pail. The tank must
be rinsed out completely and have no media or gravel left in it at all.

Loading the Media Pak
1. Remove the tank adaptor from the second mineral tank.
2. Temporarily plug the open end of the central pipe in the tank to insure that no media
falls down into the distribution.
3. Fill mineral tank one quarter full of water to protect distribution during gravel installa-
tion.
4. Slowly and carefully add the gravel support bed and the filtration media leveling each
layer as it is placed into the tank.
5. Unplug the riser tube, carefully position the tank adaptor over it and turn it into the
threads in the fiberglass tank, tightening securely into tank. Note: Ensure that the in-
ternal O-ring in the tank adaptor fits securely over the riser tube. Silicone grease or
other food grade lubricant may be applied to the O-ring to ease installation of the riser
tube. DO NOT use petroleum based lubricants as they will cause swelling of O-ring
seals.
Load the bag(s) of media into the tank in the following order:
Chem-Free Filters
1. Coarse gravel
2. Fine gravel
3. Chem-free media / OR Carbon
Connect or reconnect the inlet and outlet and drain. The control valve should be in the back-
wash position. Slowly open the inlet valve water supply and slowly fill the filter tank until
water appears at the open drain line. Return the control to the service position and shut the
inlet off for approximately one hour to allow the media to soak in the water.
After one hour, turn inlet water on slowly and place the control into the backwash position
and plug the unit’s electrical cord into a constant power source. Let the unit continue
through its regeneration cycle automatically. The regeneration is necessary so all media
fines are backwashed down the drain to ensure clean filtered water.

Cleaning or Replacing Injectors
Sediment, salt and silt will restrict or clog the injector. A clean water supply and pure salt
will prevent this from happening.
The injector assembly is located on the right side of the control valve. This assembly is
easy to clean.
1. Shut off the water supply to your softener and reduce the pressure by opening a cold
soft water faucet.
2. Using a screwdriver, remove the two screws holding the injector cover to the control
valve body.
3. Carefully remove the assembly and disassemble as shown above. The injector orifice
is removed from the valve body by carefully turning it out with a large screwdriver. Re-
move the injector throat the same way.
4. Carefully flush all parts including the screen. Use a mild acid such as vinegar or Pro-
Rust Out to clean the small holes in the orifice and throat.
5. Re-assemble using the reverse procedure.
