Application for the Combination Softener and Tannins Filter

This Combination Softener and Tannins Filter has been designed to remove tannins and hardness from your water supply.

Tannins can cause a yellow to brown colour in the water (i.e. organic colour) and also may impart taste and odour as well.

Tannins are formed by the decomposition of vegetable matter. Hardness is responsible for the deposition of calcium carbonate scale in pipes and equipment.

All tannins are not equal, the unit selected should have been with the assistance of an authorized representative or distributor. This is typically done based on a water analysis and column testing of the source water and/or with experience on other successful installations in the area on the same source water.

Application Notes about Combination Softener and Tannins Filter Units:

1. Although the STF unit was selected using the source water, the selected STF unit was the most suitable for this application, total removable of all colour contaminants may occasionally not be attained due to:

a) Multiple types of tannins in the source water. Unit media may only be successful at removing some of these organics, but not all.

b) Colour may be caused by contaminants other than organics.

c) The remaining contaminants may require removal by other methods such as activated carbon, reverse osmosis, etc.

Please consult your authorized representative or distributor for solutions.

2. Metals in the water such as Iron and Manganese can also foul the STF resin bed, reducing the ability to remove tannins and hardness. An iron filter or iron guard softener should be used to reduce the problem causing contaminants to an acceptable level. (Installation Tip: Ensure that the STF unit is only allowed to regenerate after the regeneration of the filter unit, if one is present.)

3. Turbidity caused by suspended solids and sediment can foul the STF resin bed. Removal of the turbidity can be achieved through some type of mechanical filtration such as a multi-media filter and/or cartridge filters.

4. Depending on the alkalinity of the source water being treated, the pH (alkalinity) of the water after the STF unit will likely drop for part or all of the units service run after regeneration. This is caused by the STF unit’s resin ability to also remove alkalinity in the water. Adjustment of the waters pH may be required once treated by the STF unit.

5. If “nitrates” are present in the source water, consult your authorized representative or distributor for additional solutions.

(Caution: This unit has not been designed for nitrate removal and should be dealt with separately.)

6. Occasionally, a fishy odour will occur if the source water is of a high pH, typically greater than 8.0. If this occurs, putting the unit through a couple regeneration cycles can sometimes reduce the odour. Chlorine in combination with a higher pH can also make the odour worse or more difficult to overcome as chlorine degrades the resin in the STF unit.

7. Depending on the alkalinity of the source water being treated, the chlorides in the treated water from the STF unit will increase proportionally. This may result in a bitter salty taste which should be treated with a reverse osmosis drinking water system for household drinking and cooking water.

Water Chemistry Guideline

TANNIN REMOVAL FILTER GUIDELINE FLOWCHART

There are two major groups of organics:

• The carboxylic groups - removed by ion exchange by Anion Resin

• The phenolic group - They are non-ionized and can be removed by adsorption

For effective removal, macroporous Type 1 strong base anion resin can bed used.

The performance of removal will depend on organic level, measured in total organic carbon (TOC), presence of iron

The following water contaminants are needed to be tested :

• Total Hardness*

• Iron*

• Manganese*

• Nitrates*

• pH

• Total Dissolved Solids (TDS)*

• Tannins*

• Sulphates*

• Alkalinity* * Critical

If the hardness and iron is high, the calcium and iron will precipitate and foul the anion resin which will cause an irreversible change

A separate softener will be required If Hardness <10 gpg

YES

If Iron < 0.1ppm

YES

If Manganese < 0.03ppm

YES

Check Sulphate to Nitrate Ratio to determine the anion resin

Iron Filter is required depending on Fe++, Fe+++ and pH levels, If pH is low and Fe++ concentration is low

<10ppm and no chlorine is present, Softener can be used if properly sized

** Check Fe++ and Fe+++ concentration in the field

Manganese Greensand or Iron Filter is required depending on Mn++ and pH levels, If pH is low and Mn++ is low<0.75 ppm and no chlorine is present, softener can be used

** Check Mn++ concentration in the field

Strong Acid Base Anion Resin Selectivity - Sulphate>Nitrates>Chloride>bicarbonate

Strong Acid Base Anion Nitrate Resin Selectivity - Nitrates>Sulphate>Chloride>bicarbonate

If {Nitrate/(Nitrate+Sulphate)}>0.6 (WHO Limit)

YES

Nitrate Selective Resin to be used, Capacity can be calculated by nitrate ions percentage and silica leakage

This is done to avoid nitrate dumping

Check Sulphates, Bicarbonates (alkalinity), Tannins, Nitrates concentration and calculate the capacity of OCR Resin for each of these substances and and determine the largest CF of anion resin required to be regenerated every three days - X CUFT (The capacity can be calculated by calculating the percentage of sulphate and the leakage of silica

How a WaterGroup 6200 SXT Combination Softener & Tannins Filter Works

This unit removes hardness and Tannin in the water by exchanging particles in the water, or ions. They remove hard ions the calcium and magnesium in the water by trading it for sodium ions producing soft water. Unlike the calcium and magnesium, sodium stays dissolved in water and does not form a scale. Sodium also does not interfere with the cleaning action of soaps.

The sodium is released by a charged resin contained in the softener, this resin also traps the calcium and magnesium ions.

The second layer of resin traps negatively charged tannin molecules and exchange them with Chloride ions. Eventually this resin releases all of its sodium and Chlorides and has filled up with other ions, so it then must be regenerated. Regeneration is accomplished by washing the resin with a salt saturated brine solution that removes the calcium and magnesium while replenishing the sodium and remove tannins ions in the second layer of the media bed replenishing it with Chlorides. This is why the softener requires a brine tank and salt.

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.

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.

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 distributor once media is loaded. Whenever possible, fill the tank outdoors to avoid problems with dust. If filling indoors, a dust mask should be worn.

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.)

O-ring

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.

DO NOT use petroleum based lubricants as they will cause swelling of O-ring seals.

The softener or filter is now charged with softening resin.

g. It is recommended that the softener or filter tank now be completely filled with water (SLOWLY) to soak the resin or filtration 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:

1. Clamp Ring – The clamp ring connects the control valve to the tank and provide an easy way to disconnect tank during control valve servicing. Make sure that the clamp ring screw is tightened

The “Clamp Ring” should secure the valve with the top of the flange facing up. Please note “top” on the clamp ring.

4. Attach the bypass valve to the control valve (and yoke if plastic bypass is used). Connect the inlet and outlet of the water softener to the plumbing in the house. The control valve must not be submitted to temperatures 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.

Filters are supplied with a brass service line flow control, similar to the one shown in Figure 4. The STF20 filter is supplied with a #15177 flow control housing with 3/4” x 1/2” FNPT connections and 3.5 GPM flow button. STF30 filters are supplied with a #15177 flow control housing with

3/4” x 1/2” FNPT connections and 5.0

GPM flow button. The installation of this flow control ensures the recommended service flow rate of the STF filter is not exceeded. If this flow control is not installed, some colour may bleed through at higher flow rates.

Hose Barb

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 necessary plumbing.

Connect 1/2” drain hose (not supplied) with a hose clamp here

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.

Tube Insert



One end of the brine tubing come attached to the safety float assembly

6. The brine line is connected to the safety float assembly of the brine tank. Pull the 3/8” brine line through the hole in the back of the brine tank. Connect the brine line to the fitting on the side of the valve using the nut and ferrule. Tighten snugly.

Remove the nut from the brine line of the valve and push the other end of the brine tube inside it. Make sure that the brass insert is snugged inside the brine tubing. The brine tubing should pass through both plastic inserts of the black nut.

7. Overflow Connection (Optional): In the event of a malfunction, the brine

TANK OVERFLOW will direct “overflow” to the drain instead of spilling on the floor. This fitting should be installed at the side of the cabinet or brine tank.

Brine

Tubing

To connect the overflow line, drill the hole on the side of the tank, 2 to

3 inches below from the top of the brine tank. Insert overflow fitting (sold separately part # 33006) into tank and tighten with plastic thumb nut and gasket as shown. Attach length of

1/2-inch (1.3-cm) I.D. tubing (not supplied) to fitting and run to drain. Do not elevate overflow line higher than overflow fitting.

Do not tie into drain line of control unit. Overflow line must be a direct, separate line from overflow fitting to drain, sewer or tub. Allow an air gap as per drain line instructions

19. It is suggested that for the first couple service/regeneration cycles the colour of the water should be closely monitored. If colour begins to break through prior to the calculated amount set, the gallonage setting should be reduced accordingly.

Optional Sanitization Procedure: We recommend that all new water conditioners be disinfected as part of the startup.

Water Softener Sanitization

Sanitization Solution

Press and Hold to manually regenerate

1a. Pour entire packet of Sani-System

Liquid Concentrate – Part # 50032

(24 packets) into the brine well. If no brine well is present, pour entire packet into bottom of brine tank when salt is nearly empty.

1b. Manually regenerate the softener according to the manufacturer’s specifications.

Sanitization can also achieved by the application of chlorine in the regeneration cycle of the conditioner. A liquid solution of 5.25% sodium hypochlorite (commonly referred to as household bleach) is recommended as a suitable disinfectant.

Use only unscented products. For every cubic foot of resin in the softener, pour approximately two (2) tablespoons of sodium hypochlorite into the brine well tube. The brine tank refill step of regeneration should add the correct amount of water to the brine tank. If not, the water can be added manually now. Press and hold the to begin a manual regeneration. Allow softener to complete the Brine/Rinse cycle, then let the manual regeneration continue until the brine tank is refilled again with the correct amount of water.

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.

I MPORTANT: 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

Figure 5A

Figure 5B

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.

Maintenance Instructions

Checking the Salt Level

Check the salt level monthly. Remove the lid from the cabinet or brine tank, make sure salt level is always above the brine level

NOTE: You should not be able to see water

Adding Salt

Use only clean salt labeled for water conditioner use, such as crystal, pellet, nugget, button or solar.

The use of rock salt is discouraged because it contains insoluble silt and sand which build up in the brine tank and can cause problems with the system’s operation.

Add the salt directly to the tank, filling no higher than the top of the brine well.

Bridging

Humidity or the wrong type of salt may create a cavity between the water and the salt.

This action, known as “bridging”, prevents the brine solution from being made, leading to your water supply being hard.

If you suspect salt bridging, carefully pound on the outside of the plastic brine tank or pour some warm water over the salt to break up the bridge. This should always be followed up by allowing the unit to use up any remaining salt and then thoroughly cleaning out the brine tank. Allow four hours to produce a brine solution, then manually regenerate the softener.

CAUTION! Liquid brine will irritate eyes, skin and open wounds - gently wash exposed area with fresh water. Keep children away from your water conditioner.

Resin Cleaner

An approved resin cleaner must be used on a regular basis if your water supply contains iron. The amount of resin cleaner and frequency of use is determined by the quantity of iron in your water (consult your local representative or follow the directions on the resin cleaner package).

Iron Fouling Recommended Product: PRO RUST OUT – Clean iron from resin media bed with a reducing agent such as sodium bisulfite or sodium hydrosulfite by adding it to the brine tank down the brine well and allowing time to mix.

Manually regenerate softener (see instructions on bottle on cleaning of water softeners).

Calcium Carbonate Recommended Product: PRO Res-Care – Clean calcium carbonate from resin media with a mild acid solution such as phosphoric acid. Do this by adding cleaning product to the brine tank via the brine well and then manually regenerate. Once complete, manually regenerate again with salt brine (see instructions on bottle on cleaning of water softeners).

Care of Your Softener

To retain the attractive appearance of your new water softener, 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).

Servicing Components.

• The injector assembly should be cleaned or replaced every year depending on the inlet water quality and water usage.

• The seals and spacer cartridge should be inspected/cleaned or replaced every year depending on the inlet water quality and water usage.

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.

Res-Up® Feeder Installation Instructions

1. Remove top cover, fill the

Res-Up® Feeder (plastic container) to the top with water so that the wick retaining clip, tube and wick are wetted, allow to soak for 15 minutes or more.

2. Empty water and pull tube and wick through Feeder until slack is removed from inside. The outlet end tube and wick must be below the bottom level of the Res-Up®

Feeder.

3. Drill two 1/4” holes in brine tank as shown.

4. Drill a 5/8” hole in the brine well cap.

5. Clip mounting bracket over feeder with “hooks” pointed up.

Insert end of tube in the brine well cap and mounting bracket with the 1/4” holes in the brine tank, rotating feeder downward into position as shown in Figure 1.

6. Fill Feeder with Res-Up® Cleaner to “Fill Line” on label.

7. Replace cover on Feeder and automatic feeding will occur in a few hours.

Res-up feeder

5/8" hole in brine well cap

1/4” Holes

Res-Up Feeders attach to your brine tank and automatically dispense the Res-Up cleaner into the brine solution where it cleans the resin during the regeneration cycle.

The feeder hooks onto the tube inside your brine tank and you just pour some chemical in it and your water softener should last significanly longer. A res-up feeder is essential if your raw water contains measurable amounts of iron.

Res-up Feeder Bottle (Chemical sold Separately)

The 12 cc feeder (Part # 33010) is for softeners up to 64,000 grains (2 ft3 of resin) .

The 30 cc feeder (Part # 33018) is for larger softeners over 64,000 grains.

1. Reconnect brine tube and drain line.

2. Return bypass or inlet valve to normal in service position. Water Pressure will automatically build in the softener.

NOTE: Be sure to shut off any bypass line.

3. Check for leaks at all sealed areas. Check Drain seal with the control in the backwash position.

4. Plug electrical cord into outlet.

5. Set Time of Day and cycle the control valve manually to assure proper function. Make sure control valve is returned to the In Service position.

6. Verify the salt level in the brine tank is sufficient. Start regeneration cycle manually if water is hard.

Error Code

[Err 0]

[Err 1]

Probable Cause

Drive motor is stalled

Drive motor is running continuously

[Err 2]

[Err 3]

There have been more than 99 days since the last Regeneration. If the Day of the Week mode of regeneration is selected and days since last regeneration exceeds 7 days.

[ 7 - - 5 ]: There have been more than 7 days since the last regeneration. All individual settings (d1, d2, d3, d4, d5, d6, d7) are set to

Control board memory failure.

Recover and Resetting

Unplug the unit from the power source

When power is restored to the unit, the Err _ display code clears. If the condition causing the error has not been resolved the Err _ code reappears in the four digit display. Do not attempt to troubleshoot this problem any further.

Regeneration must occur for the unit to recover, the display to clear and the valve to function normally.

[ 7 - - 5 ]: To recover from [Err2], the user must initiate a regeneration or set at least one individual day to 1.

Perform a Master Reset. If the error returns, do not attempt to troubleshoot this problem any further.

Error Display Example

NOTE: Unit will flash when an error exists.

Trouble Shooting Guide

PROBLEM: Fishy or unpleasant odour is apparent in the treated water that is not present in the untreated water.

1. pH of the incoming water may be high.

2. pH of the incoming water maybe high in combination with chlorine present for disinfection.

• This odour may be apparent on startup and will typically be reduced or eliminated after a couple service runs and regenerations cycles of the STF unit.

• The addition of chlorine along with high pH typically increases the chances that an odour will be present in the treated water With the presence of chlorine, it is unlikely odour will be eliminated. Chlorine can be removed through the use of an activated carbon filter, however it is highly recommended that additional disinfection methods be re-employed downstream of the STF unit with Ultraviolet Sterilizers or Chlorination Pumps.

Problem: STF unit was removing colour from water, but then starts to show colour again until regeneration.

Then colour is removed again.

1. Capacity of STF unit is being over run and resulting in tannins not being removed near the end of service run.

• Decrease the gallons between service runs to a point where no coloured water is appearing between one regeneration to the next.

PROBLEM: STF unit was removing colour from water, but then starts to show colour earlier and earlier into service run.

PROBLEM: STF unit was removing colour from water, but no longer seems to be effective.

1. Regeneration is not being performed adequately.

• Check to see if salt is in brine tank. If no salt is present, last regeneration(s) may have been done without salt brine. Add salt to brine tank and manually regenerate STF until after allowing brine to dilute in water for at least four (4) hours.

• Check to see if brine tank is being refilled with water properly at the end of the regeneration cycle and/or if water is being drawn into the valve during the brine draw cycle. Injector & Screen or Brine Valve may be plugged and require cleaning.

• Check to see that valve settings are correct.

2. Regeneration is not being performed at all.

• Check gallonage setting between regenerations. Capacity set may be too large.

• Check to see that meter is turning and properly connected via the meter cable to the timer.

• Check to ensure that Bypass Valve is not open and bypassing the STF unit with untreated water.

3. Resin Media may be backwashing to drain.

• Confirm backwash flow control is installed on drain line and check that backwash flow control has not been swapped for service line flow control.

• Monitor drain line during regeneration cycle and check that no resin beads are exiting the

STF unit.

4. STF unit resin media may be fouled with organics. Check resin visually to confirm.

• Try manually regenerating STF unit two or three times in a row. Allowing approximately four

(4) hours between regenerations to allow salt brine to be saturated.

• As a last resort, try adding approximately four (4) ounces of household bleach (5.25%) into the brine well. Begin a manual regeneration. Monitor the drain line for a strong chlorine odour which should occur in the brine draw cycle . When odour is present, halt regeneration by unplugging unit and shutting down water flow to the STF unit via the bypass valve. Shutdown STF unit for approximately two (2) hours, then continue regeneration by plugging unit back in and replacing bypass valve to service position. Only try this step as a last resort as chlorine will degrade the resin bed. If unsuccessful, see next step.

• Resin bed may have become permanently fouled due to infrequency of regenerations or nature of tannins causing colour in water. Replace resin media bed and check to see that regeneration frequency is adequate or consult your dealer.

Trouble Shooting Guide

5. STF filter resin media may be fouled with Iron. Check visually to confirm.

• Iron should typically be removed prior to the STF unit. Install an iron filter upstream of STF unit.

• Clean iron from resin media bed with a reducing agent such as sodium bisulfite or sodium hydrosulfite by adding it to the brine tank down the brine well and allowing time to mix.

Manually regenerate softener.

Recommended Product: PRO RUST OUT — see instructions on bottle on cleaning of water softeners.

• If resin bed cannot be cleaned, it may be permanently fouled with iron. Replace resin media bed and install treatment upstream of STF unit to remove iron.

6. STF filter resin media may be fouled with Calcium Carbonate.

• Calcium Carbonate fouling is the result of hardness precipitating onto the resin media.

• Clean calcium carbonate from resin media with a mild acid solution such as phosphoric acid. Do this by adding cleaning product to the brine tank via the brine well and then manually regenerate. Once complete, manually regenerate again with salt brine.

Recommended Product: PRO Res-Care — see instructions on bottle on cleaning of water softeners.

PROBLEM: STF unit appear to be causing a high pressure drop in home water system.

1. Pressure drop may be due other factors.

• Confirm pressure loss is due to the STF unit, and not the result of distribution or well pump problem.

• Confirm pressure loss is due to STF unit by checking flow while in BYPASS mode.

• Check that flow demand is not exceeding rated flow rate of STF unit. STF units are supplied with a SERVICE LINE FLOW CONTROL to ensure maximum effectiveness is maintained.

Attempting to exceed this flow control rating will result in a pressure drop. STF unit should be increased in size to compensate for larger demand.

NOTE: Do not remove this FLOW CONTROL from valve outlet. It will likely result in a decrease in STF unit performance.

• See troubleshooting notes above on dealing with fouling problems.

2. Pressure loss may be due to fouling from Organics, Iron or Calcium

Carbonate.

3. Pressure loss may be due to Resin

Media being plugged with Silt and

Turbidity.

• Try manually regenerating STF unit and extending the backwash by unplugging unit during the first cycle that begins to send water to the drain. Monitor water to the drain and watch for dirt and silt. If present, continue this backwash cycle until water runs clear then plug unit and allow valve to finish regeneration normally.

• Install multi-media filter or 5 micron cartridge filter ahead of STF unit to remove Silt and

Turbidity.

PROBLEM: STF unit appears to be removing most of the colour in the water, but some still passes through.

1. Raw water may be partially slipping past STF unit or the Organics (Tannins) not being removed may be impervious to the resin media in the STF unit.

• Check to see that SERVICE LINE FLOW CONTROL is in place on the valve outlet. Flowrates higher than recommended through the STF unit may be causing some leakage of colour.

• Check to see that BYPASS valve is not partially open and bleeding some raw water to distribution lines.

• Check that pipelines after STF unit are not lined with organics that are slowly being stripped away. Lines may require flushing.

• If all equipment and distribution sources of problem have been eliminated, consult your water treatment dealer, who may try to “polish” the remaining colour after the STF unit with an ACTIVATED CARBON filter or cartridges or other treatment method.
