How a Duro Manganese Greensand Filter Works
Your automatic iron filter is an ingeniously simple and reliable design. The unit consists of a bed of filter media contained
in a fiberglass tank; a specially designed feeder containing potassium permanganate for the regeneration of the filter
and a proven automatic control. Raw water enters your home through the main supply line, enters your iron filter and passes
down through the filter media. Any iron, manganese or hydrogen sulfide present in your water supply is exposed to oxygen
stored in the filter media. The oxygen causes precipitation of the minerals and they are trapped in the filter media. Only
clean filtered water flows to your household water line. The filter media is periodically regenerated, automatically backwashing the trapped minerals to the drain and replacing the oxygen. This is done by introducing potassium permanganate
to the media.
1. Your automatic iron filter can be programmed to operate according to your needs by making the appropriate settings on
the timer. On the days your filter regenerates, the operating cycles will be automatically performed. In the service position, filtered water is supplied for household use.
2. The automatic control reverses the flow of the water through the filter, backwashing minerals trapped in the filter
to the drain.
3. The control pulls a vacuum on the feeder. This causes an exact volume of saturated potassium permanganate solution to
be drawn into the filter tank.
4. The control slowly rinses the chemical through the media tank. The potassium permanganate supplies oxygen to the filter
media.
5. The control fast rinses the media bed to settle it and to ensure that all the chemical and mineral precipitate is removed.
6. The control adds water to entirely fill the previously evacuated feeder. The feeder is now ready for the next regeneration.
The control puts the system into service, supplying iron-free water to the household. All this is performed automatically over
a period of 2 ¾ hours. Water runs to the drain for approximately 80 minutes
The water softener can run for days before running out of sodium, and when it does, the sodium is replenished
in only a matter of a few hours.
In normal operation, the Time of Day display will alternate being viewed with the Volume Remaining display. This display will
be in gallons or liters. As treated water is used, the Volume Remaining display will count down from a maximum value to zero
or (---). Once this occurs, a regeneration cycle will be initiated at the Set Regeneration Time. Water flow through the valve is
indicated by the Flow Indicator that will flash in direct relationship to flow rate.

Timer Behavior During Regeneration
In regeneration, the control will display a special regeneration display. In this display, the control will show the current
regeneration step abbreviation the valve is advancing to or has reached and the time remaining in that step. The step
abbreviation displayed will flash until the valve has completed driving into this regeneration step position. Once all
regeneration steps have been completed, the valve will return to Service and resume normal operation.

Sizing and Operating Requirements
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 20 psi (137 kPa). If the existing system cannot do this, it must be upgraded to do so. Whenever possible, the water system should be adjusted to deliver at least 30 psi (206.8 kPa) for even more satisfactory results. Maximum
pressure should not exceed 100 psi (689 kPa).
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 in the above specification
chart.
Capacity
An iron filter with one cubic foot of filter media regenerated with one Potassium Permanganate feeder will work well for
most residential applications. For example, with iron in the range of 3-6 ppm, most filters will need to regenerate every two
or three days providing an average family size of four or five people. The specification chart above shows the iron removal
capacity in ppm that can be expected on automatic iron filters. The specifications are based on obtaining 6,000 ppm of
capacity for each cubic foot of filter media. Two different Potassium Permanganate feeders are available – one feeding
2 oz. per regeneration, the other feeding 4 oz. In order to obtain the above capacities, the pH of the water being treated
must be 7.0 or above. In the event the water is below 7.0, it must be treated with the appropriate equipment before going
through the filter.
Removal of Iron, Manganese & Hydrogen Sulfide
For the purpose of sizing a filter, consider 1 ppm of manganese equal to 2 ppm of iron and 1 ppm of hydrogen sulfide equal
to 3 ppm of iron. Manganese and hydrogen sulfide (sulfur) are more difficult to oxidize than iron. Therefore, we suggest that,
when making your sizing calculations and regeneration frequency calculations, calculate iron x 1, manganese x 2 and hydrogen sulfide x 3. All three must equal less than 10 ppm. Manganese is often present in water when iron is present. Hydrogen sulfide can normally be identified by a strong rotten egg odor

Installation Instructions
Contact your local distributor to use WaterGroup laboratory for complete water analysis free of cost and no
obligation to you.
All government codes and regulations governing the installation of these devices must be observed.
.
If the ground from the electrical panel or breaker box to the water meter or underground copper pipe is tied
to the copper water lines and these lines are cut during installation of the Noryl bypass valve and/or poly
pipe, an approved grounding strap must be used between the two lines that have been cut in order to maintain continuity. The length of the grounding strap will depend upon the number of units being installed and/or
the amount of copper pipe being replaced with plastic pipe. See Figure 1.
In all cases where metal pipe was originally used and is later interrupted by poly pipe or the Noryl bypass valve as in Figure
1 or by physical separation as in Figure 2, an approved ground clamp with no less than #6 copper conductor must be used
for continuity, to maintain proper metallic pipe bonding.
NOTE: Check your local electrical code for the correct clamp.

Preparations
1. Determine the best location for your water filter, bearing
in mind the location of your water supply lines, drain line
and 120 volt AC electrical outlet. Subjecting the softener
to freezing or temperatures above 43°C (110°F) will void
the warranty.
2. Media Installation (When Necessary). Models including
and higher than 1.5 CF of media are shipped with separate media in pails or boxes. Models lower than 1.5 CF of
media come loaded with media and this step can be
skipped for new installation.

The filter is now charged with resin.
g. It is recommended that the softener or filter tank now be completely filled with water (SLOWLY) to soak the resin or filtra-
tion media before startup. This will allow the media to absorb water as well as help displace any trapped air. This will
reduce the chance of backwashing resin or filter media out of the tank during the initial backwash on startup.
3. Outside faucets used to water lawns and gardens should not supply softened water. A new water line is often required to
be connected to supply hard water to the inlet of the water softener and to the outside faucets.
Cut the water line between where it enters the house and before any lines that branch off to feed the hot water heater
or other fixtures in the house and as near the desired location of the water softener as possible. Install a tee fitting on
the feed end of the cut pipe, and an elbow fitting on the other end. Install piping from the tee to the inlet of the water
softener and from the elbow to the outlet of the softener. To sever the water lines which branch off to feed any outside
faucets, cut the branch lines approximately two inches from the fitting on the main water line. Install an elbow on the
end of the pipe nearest the outside faucet and a cap on the end connected to the existing water line. Install piping from
the tee installed on the inlet line to the water softener to the elbow installed on the pipe to the outside faucet. Following
this procedure will result in all lines in the house, with the exception of the outside faucets, but including the water heater
and therefore the hot water lines, being supplied with soft water.
Installation Steps:

Controller Behavior
Control Operation During Programming
The control will only enter the Program Mode with the valve in Service. While in the Program Mode, the control will
continue to operate normally, monitoring water usage and keeping all displays up to date. Control programming is stored
in memory permanently, eliminating the need for battery back-up power.
Meter Immediate Control
A meter immediate control measures water usage and regenerates the system as soon as the calculated system capacity
is depleted. The control calculates the system capacity by dividing the unit capacity (typically expressed in grains/unit
volume) by the feedwater hardness and subtracting the reserve. Meter Immediate systems generally do not use a reserve
volume. However, in twin tank systems with soft-water regeneration, the reserve capacity should be set to the volume
of water used during regeneration to prevent hard water break-through. A Meter Immediate control will also start a
regeneration cycle at the programmed regeneration time if a number of days equal to the regeneration day override
pass before water usage depletes the calculated system capacity.
Meter Delayed Control
A Meter Delayed Control measures water usage and regenerates the system at the programmed regeneration time after
the calculated system capacity is depleted. As with Meter Immediate systems, the control calculates the system capacity
by dividing the unit capacity by the feedwater hardness and subtracting the reserve. The reserve should be set to insure
that the system delivers treated water between the time the system capacity is depleted and the actual regeneration
time. A Meter Delayed control will also start a regeneration cycle at the programmed regeneration time if a number of
days equal to the regeneration day override pass before water usage depletes the calculated system capacity.
Time Clock Delayed Control
A Time Clock Delayed Control regenerates the system on a timed interval. The control will initiate a regeneration cycle at
the programmed regeneration time when the number of days since the last regeneration equals the regeneration day
override value.
Day of the Week Control
This control regenerates the system on a weekly schedule. The schedule is defined in Master Programming by setting
each day to either “off” or “on.” The control will initiates a regeneration cycle on days that have been set to “on” at the
specified regeneration time.
Control Operation During a Power Failure
The SXT includes integral power backup. In the event of power failure, the control shifts into a power-saving mode. The
control stops monitoring water usage, and the display and motor shut down, but it continues to keep track of the time and
day for a minimum of 48 hours.
The system configuration settings are stored in a non-volatile memory and are stored indefinitely with or without line power.
The Time of Day flashes when there has been a power failure. Press any button to stop the Time of Day from flashing.
If power fails while the unit is in regeneration, the control will save the current valve position before it shuts down. When
power is restored, the control will resume the regeneration cycle from the point where power failed. Note that if power fails
during a regeneration cycle, the valve will remain in it’s current position until power is restored. The valve system should
include all required safety components to prevent overflows resulting from a power failure during regeneration.
The control will not start a new regeneration cycle without line power. If the valve misses a scheduled regeneration due to
a power failure, it will queue a regeneration. Once power is restored, the control will initiate a regeneration cycle the next
time that the Time of Day equals the programmed regeneration time. Typically, this means that the valve will regenerate
one day after it was originally scheduled. If the treated water output is important and power interruptions are expected,
the system should be setup with a sufficient reserve capacity to compensate for regeneration delays.

During Regeneration
Automatic Bypass
The regeneration cycle lasts approximately 2 hours, after which soft water service will be restored. During regeneration, hard
water is automatically bypassed for use in the household. Hot water should be used as little as possible during this time to
prevent hard water from filling the water heater.
IMPORTANT: This is why the 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.
New Sounds
You may notice new sounds as your water softener operates. The regeneration cycle lasts approximately 2-1/2 hours. During
this time, you may hear water running intermittently to the drain.
Water Bypass

Outlet
Inlet
Outlet
Inlet
Manual Bypass (Figure 5A)
In case of an emergency such as an overflowing brine tank, you can isolate
your water softener 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 softener,
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 softener. However, the water you use will
be hard. To resume soft water service, open the bypass valve by rotating the
knobs counter-clockwise.
Stainless Steel Bypass (Figure 5B)
In normal operation the bypass lever is aligned with the inlet/outlet with the
pointer on SERVICE. To isolate the softener or filter, rotate lever counter clockwise until it stops and pointer indicates unit is in bypass.
You can use your water related fixtures and appliances as the water supply is
bypassing the softener and filter. However, the water you use will be hard or
untreated. To resume treated water service, open the bypass valve by reversing the rotation of the lever.

To determine the frequency of regeneration, use this procedure:
Setting the Frequency of Automatic Regeneration (SXT Models)
Please enter the ppm of compensated iron per gallon of water to be removed. See Step #4 of “User Programming.”
The SXT valve will automatically calculate the number of gallons of water to be treated by the iron filter between
regenerations.
Iron Content in the Feed Water:
ppm of capacity between regenerations (see Specifications - Page 1)
÷ ppm of iron in the water sample*
= number of gallons supplied between regenerations
- reserve capacity (number of people x 75 gallons)
Example - Using 5600 SXTM-948IF + 1 Feeder
6000 ppm between regenerations
÷ 8 ppm of compensated iron [To be entered by the user]
= 750 gallons between regenerations [See step #5 of “User Programming”]
- 375 gallons reserve capacity (5 people x 75 gallons)
= 375 GALLONS - BETWEEN REGENERATIONS [Calculated by valve]
* 1 ppm of manganese = 2 ppm of iron; 1 ppm of hydrogen sulfide = 3 ppm of iron
Days:
Total amount of iron to be removed between regenerations -
÷ ppm of iron to be removed per day
= NUMBER OF DAYS BETWEEN REGENERATIONS
Example:
5 people in the household
x 75 gallons of filtered water per person
= 375 gallons of filtered per day
x 8 ppm of compensated iron
= 3,000 PPM OF IRON TO BE REMOVED PER DAY
Using 5600 SXTM-948IF + 1 Feeder
6,000 ppm capacity
÷ 3,000 ppm to be removed per day
= 2** DAYS BETWEEN REGENERATIONS
**Maximum number of days between regenerartions should be 12.

Page 21
Manual Regeneration Cycle
If you run out of filtered water because of inadequate regeneration frequency, inadequate reserve capacity, power
failure or unusually high water usage, you can initiate a manual regeneration simply by pressing the extra cycle button.
The filter will now automatically complete a regeneration cycle and return to service. If possible, avoid water use during
the regeneration cycle.
Once you have set your filter you may experience frequent loss of water pressure, you may have to increase the
frequency of regeneration by decreasing the number of gallons between regeneration.
Potassium Permanganate Feeder
The potassium permanganate feeder assembly incorporates a non-pressurized storage tank and innovative new grid
design along with a dependable float valve.
The attractive 10” x 16” black tank is made of touch blow-molded high density polyethylene. It has a potassium
permanganate capacity of 30 lbs. and a liquid capacity of 5 gallons.
The black injection molded cover is securely fastened with three stainless steel safety screws to prevent access by children
and pets. Also, the potassium chemical tank should be placed where it is free from possible upset or access by children or
pets.
Chemical warning label and drain caution label are affixed to unit.
The unique polypropylene grid pad refuses to allow even the finest grade of undissolved potassium permanganate to
pass through the grid. This permits efficient use of our assembly with all grades of potassium permanganate. Standard grid
platform height is 6”. Additional heights are available - consult factory.

The unit is shipped fully tested and assembled and weighs approximately 7 lbs. The feeder assembly includes:
10” x 16 “ black tank Black injection molded cover
3 Stainless steel safety screws Grid with polypropylene grid pad

Correct water temperature is important for obtaining
properly dissolved potassium permanganate.
Tables based on permanganate solubility of 4 oz/gal at 50°F or 8 oz/gal at 72°F.
Float setting is based on distance between brine valve top body nut and the bottom of the float with the valve in the
closed (float up) position.
All dimensions nearest 1/4 inch.
Iron and Manganese Removal
A recommended dose of 2 oz. to 6 oz. of potassium permanganate per cubic foot of manganese greensand is
suggested for regeneration. Correct water temperature is important in obtaining proper dissolving of potassium
permanganate. At 50°F (10°C), 4 oz. of potassium permanganate can dissolve in one gallon of water. At room
temperature 72°F (22°C), 8 oz. will dissolve in one gallon of water.

Servicing 6200 Valve
Before Servicing
1. Turn off water supply to conditioner :
a. If the conditioner installation has a 3 valve bypass system first open the valve in the bypass line, then close the valves at
the conditioner inlet & outlet.
b. If the conditioner has an integral bypass valve, put it in the bypass position.
c. If there is only a shut-off valve near the conditioner inlet, close it.
2. Relieve water pressure in the conditioner by stepping the control into the backwash position momentarily. Return the
control to the In Service position. (Refer to programming instructions)
3. Unplug Electrical Cord from outlet.
4. Disconnect brine tube and drain line connections.
WARNING! ELECTRICAL SHOCK HAZARD! UNPLUG THE UNIT BEFORE REMOVING THE COVER OR ACCESSING ANY
INTERNAL CONTROL PARTS.
