Introduction

Basic Principles
The success of the installation will depend, to a great extent, on advanced planning and preparation. Careful attention
to the location of the unit, accessibility to electrical and drain facilities, and the availability of the proper tools will ensure a
professional-looking installation. Of utmost importance is the assurance that the filter has been properly applied and meets
all specifications.
Application
Correct application is directly associated with the performance and life expectancy of any water filter. It is important, there-
fore, to understand how your WaterGroup Water Filter functions and to know its capabilities and limitations so that a correct
application can be made. By following the guidelines and recommendations set forth in this manual, you can be certain
your filter is applied correctly.
MMF Filter
The Automatic Water Filter is capable of removing particulate matter particle size as small as 30 microns. It will not remove
color, organics, colloidal turbidity or dissolved solids. Some applications include:
• Removal of suspended matter in any water system
• Removal of particulate matter, such as clay, mud, etc.
• Prefiltration of oxidized iron prior to an automatic or manual softener
• Removal of light sand
The quality and number of gallons of filtered water between backwashes will depend upon the amount, type, and size
of the particulate matter being filtered. If a water sample is sent to a laboratory, where application of a MMF Type unit is
contemplated. The laboratory will test for Nephelometric Turbidity Units (NTU) and suspended solids (mg/L). The sample will
also be filtered through 10 micron filter paper and NTU run on a filtered sample. If the NTU of the raw water exceeds 150,
suspended solids exceed 150 mg/L, or the filter water throught the 10 micron filter paper has unacceptable quality, a MMF
filter might not be applicable. As a guide, the U.S. Public Health Drinking Water standards states the turbidity should not
exceed 1 NTU. The exact number of gallons filtered between backwashes can not be given because of many variables.
ACF Filter
Automatic Water Filter with Activated Media will control chlorine taste and odor, and it will also remove most objectionable
organic colors. It will not remove hydrogen sulfide. It is important to note that whenever the cause of an objectionable taste
or odor has not been established, Health Authorities should determine if the water is safe to drink. Do not use with water that
is microbiologically unsafe or of unknown quality without adequate disinfection before or after the system.
NF Filter
Automatic Water Filter with Neutralizing Media will neutralize slightly acid water (pH 5.2 to >6.8) and thus help to prevent
unsightly brown or green stains due to corrosion of household plumbing. If the pH is between 5 and 6, one part of Magne-
sium Oxide Media should be mixed with five parts of Calcite Media to provide additional neutralizing capability. If the water
to be treated has a pH less than 5, a high hardness, or a high carbon dioxide level, NF might not be applicable; a solution
feeder should be used. Because NF adds hardness, it should be used prior to a softener.
NOTE Under dynamic conditions it might be necessary to mix five parts Calcite with one part Magnesium
Oxide to effectively raise the pH. In order to size and apply the equipment correctly, a complete analysis of the
water supply should be obtained.
CAUTION! Do not use where the water is microbiologically unsafe or with water of unknown quality without
adequate disinfection before or after the unit.

How a Duro Automatic Backwashing Filter Works
Raw water enters your home through the main supply line, enters your filter, and passes downward through the media bed
Impurities such as turbidity and sediment (MMF) and organics (ACF) are removed from the water. The filtered water then
flows up and into your household water lines. The neutralizing filter (NF) is designed to raise the pH of your water to eliminate
corrosive characteristics. Periodic regeneration is required to flush entrapped material from the system.
Example: A pH of 5.5 can be raised to 7.0 which is neutral. When the water is neutralized it is then possible to remove the iron
with the addition of an iron filter.
In normal operation, the Time of Day display will alternate being viewed with the Day Remaining display. As day passes,
the day remaining 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.
Example 3 Days Remaining
to Regenerate
0 Days Treated
Water Remaining
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.
Example Less than 6 minutes

Step Rapid Rinse
Pushing the during a regeneration cycle will immediately advance the valve to the next cycle step position and
resume normal step timing.

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 main-
tain 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.

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 filter 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 sepa-
rate 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.
a) Remove the valve from
the mineral tank.
b) Temporarily plug the open end
of the riser tube to ensure that no
resin or gravel falls down into the
distribution.
The riser (distributor) remains
inside the tank seated in the
depression at the bottom.
Plug tube with a tape.
Remove after media is loaded.
Fill support bed first. (if supplied)
The media will not always spill down
inside the tank and may need to be
swept inside.

c. Fill mineral tank one quarter full of
water to protect distribution during
gravel installation.
d. Place the media into the tank in the
order indicated above. Slowly and
carefully add the gravel support
bed and the softener or filtration
media leveling each layer as it is
placed into the tank.
e. Fill support bed (if supplied) first.
During the filling process, ensure the
distributor tube stays on the bottom
of the tank, reasonably centered.
Remove the tape from the distribu-
tor once media is loaded. Whenever
possible, fill the tank outdoors to
avoid problems with dust. If filling
indoors, a dust mask should be worn.
f. Unplug the riser tube, carefully position the valve over it and turn the valve into
the threads in the fiberglass tank, tightening securely into tank. Note: Ensure
that the internal O-ring in the valve fits securely over the riser tube. Silicone
grease (part # 92360) or other food grade lubricant may be applied to the O-
ring to ease installation of the riser tube.
The large funnel (sold separately part
# 43000) makes filling the tank easier
and neater. (Or an empty 1 gallon or 4
liter container with the bottom cut out
makes a good funnel.)

NOTE: Some medias like used in Neutralizer Filter are sacrificial and deplete faster depending on inlet water
conditions and usage. The media replenishment is more frequent in high water usage and more acidic
water cases.

The filter is now charged with media.
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.
CAUTION! Make sure that the unit is de-pressurized before
conducting this task.

4. Attach the bypass valve to the con-
trol valve (and yoke if plastic bypass
is used). Connect the inlet and outlet
of the water softener to the plumb-
ing in the house. The control valve
must not be submitted to tempera-
tures above 43°C (110°F). When
sweat fittings are used, to avoid
damaging the control valve, solder
the threaded copper adapters to
the copper pipe and then, using
Teflon tape, screw the assembly into
the bypass valve.
Waste connections or drain outlet shall be designed and constructed to provide for connection to the sanitary
waste system through an air-gap of 2 pipe diameters or 1 inch (22 mm) whichever is larger.
Never insert drain line directly into a drain, sewer line, or trap. Always allow an air gap between the drain line and
the wastewater to prevent the possibility of sewage being back-siphoned into the conditioner.
5. Drain Line Connection: Using teflon
tape, screw the 1/2” hose barb into
the drain port in the valve. Attach
1/2” drain hose to the hose barb and
tighten securely with a hose clamp.
Run the drain line to a floor drain or a
laundry drain. Complete any neces-
sary plumbing.

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 days and keeping all displays up to date. Control programming is stored in
memory permanently, eliminating the need for battery back-up power.
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 15 minutes, after which treated water service will be restored. During regenera-
tion, untreated water is automatically bypassed for use in the household. Hot water should be used as little as possible dur-
ing 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
Manual Bypass (Figure 5A)
In case of an emergency such as an overflowing brine tank, 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 softener. However, the water you use will be hard. To
resume treated 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 clock-
wise 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 revers-
ing the rotation of the lever.

Care of Your Filter
To retain the attractive appearance of your new water filter, clean occasionally with a mild soap solution. Do not use
abrasive cleaners, ammonia or solvents. Never subject your softener to freezing or to temperatures above 43°C (110°F).

Please refer to the servicing section of this manual for step by step procedure.
Not following the above will void all warranty on the control valve.
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.
Replacing Media Bed
NF - the media bed in a neutralizing filter is slowly dissolved and has to be replaced. The frequency of replacement varies,
depending on water quality - consult your dealer to determine the expected life of your media bed.
ACF - under normal operating conditions the effective life of the filter media is approximately one to three years
depending on the water quality, after which, taste and odor problems may return. When this happens contact your dealer
for a replacement media bed.
MMF - under normal operating conditions, the media should never need to be replaced. If you experience pressure loss
and cannot correct it with a manual regeneration, your media bed may need replacing - contact your deale
Maintenance Instructions
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.
3. Unplug Electrical Cord from outlet.
4. Disconnect drain line connection.
WARNING! ELECTRICAL SHOCK HAZARD! UNPLUG THE UNIT BEFORE REMOVING THE COVER OR ACCESSING ANY
INTERNAL CONTROL PARTS.
CAUTION! Disassembly while under pressure can result in flooding. Always follow these steps prior
to servicing the valve.
