How Your 5600 SE Water Filter Works

The chemical free iron filter consists of two major components which are:

1. A Mazzei injector, located between the well head and the pressure tank, adds a small amount of air to the ironladen water whenever the well pump runs.

2. A backwashing-type filter containing special media that causes the iron in the air-injected water to precipitate throughout the filter bed This process produces an iron removal capacity of up to 30,000 ppm. The media requires no chemical regenerant for oxygen enrichment.

Periodic backwashing of the filter bed flushes the precipitated iron to the drain and readies the filter for use again. The duration of the backwash procedure will vary depending on the iron concentration but generally is 10 minutes total. The frequency of backwashing depends on iron concentration and water usage and ranges from daily to once every 10 days.

In normal operation, the Time of Day display will alternate being viewed with the Volume Remaining display. This display will be in gallons. 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 Dot that will flash in direct relationship to flow rate.

In regeneration, the control will display a special regeneration display. In this display, the control will show the current regeneration step number the valve is advancing to or has reached and the time remaining in that step. The step number 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

Pushing the Extra Cycle Button during a regeneration cycle will immediately advance the valve to the next cycle step position and resume normal step timing.

1. The manufacturer reserves the right to make product improvements which deviate from the specifications and descriptions stated herein without obligation to change previously manufactured products or to note the change.

2. Peak flow rates are intended for intermittent use only and are for residential application only.

Caution: These water conditioners are not intended to be used for treating water that is microbiologically unsafe or of unknown quality without adequate disinfection before or after the system.

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.

Control Operation During a Power Failure

During a power failure, all control displays and programming will be stored for use upon power re-application. The control will retain these values for years, if necessary, without loss. The control will be fully inoperative and any calls for

regeneration will be delayed. The control will, upon power re-application, resume normal operation from the point where it was interrupted. An indication that a power outage has occurred will be an inaccurate Time of Day display.

Before Installation

Inspection and Handling of Your Chemical Free Iron Filter

Inspect the equipment for any visible shipping damage. If damaged, notify the transportation company and request a damage inspection. Damage to cartons should also be noted.

Handle the filter unit with care. Damage can result if the unit is dropped or set on sharp, uneven projections on the floor. Do not turn the filter unit upside-down.

NOTE: If a severe loss in water pressure is observed when the filter unit is initially placed in service, the filter tank may have been laid on its side during transit. If this occurs, backwash the filter to "reclassify" the bed.

Iron (Fe)

Iron concentrations as low as 0.3 ppm can cause staining. The iron concentration, the flow rate demand and the consumption rate of the water are used to determine the size of the basic filter system. The higher these factors are, the larger the required system. The chemical free iron filter is capable of filtering out soluble iron (also known as "clear water" or ferrous iron) and precipitated iron (also known as "red water" or ferric iron). There is no apparent upper limit of iron concentration for the chemical free iron 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 levels above 0.5 ppm.

Manganese (Mn)

The presence of manganese can be bothersome 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 chemical free iron filter to remove manganese depends on its concentration and the pH of the water.

The pH of water measures its acidity or its alkalinity. Water with a pH of less than 7.0 is acidic, more than 7.0 is alkaline and 7.0 is neutral. The lower the pH value is below 7.0, the greater the acidity and higher the pH value is above 7.0, the more alkaline. Acidic water is corrosive to pipes, appliances, etc. A pH of 7.0 or higher facilitates iron removal.

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 recommended for this situation. If the tannin concentration is less than 0.5 ppm, a chemical free iron filter may be installed.

Hydrogen Sulfide (H2S)

Hydrogen sulfide (often referred to as sulfur) is easily detectable by its objectionable "rotten egg" odor. Sulfur corrodes iron, brass, copper and silver. A chemical free iron filter is not recommended when hydrogen sulfide is the only water problem, although it is capable of removing sulfur in concentrations of up to 3 ppm. Whenever hydrogen sulfide is present, backwashing must be performed at more frequent intervals and the pumping system must include a standard air-to-water pressure tank with an air relief valve.

Checking Your Water Pressure and 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. If pressure is over 100 psi, a pressure reducing valve must be installed in the water supply line ahead of the Mazzei injector. NOTE: If you have a municipal or community water supply and daytime water pressure is 85 psi or more, nighttime pressure may exceed 100 psi. Call your local water department or plant operator to obtain pressure readings. If you have a private well, the gauge on the pressure tank will indicate the high and low system pressure. Record your water pressure data below: Low __________________ psi High __________________ psi

2. The pumping rate of your well pump must be at least 5 gallons per minute (gpm) for satisfactory operation of the Mazzei injector. In addition, the pumping rate must equal the backwash flow rate of your filter. To measure the pumping rate of your pump, follow these instructions: a. Make certain no water is being drawn. Open spigot nearest pressure tank. When pump starts, close spigot and

measure time (in seconds) to refill pressure tank (when pump shuts off). This figure represents cycle time.

b. 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.

c. Divide the draw down figure by the cycle time and multiply the result by 60 to arrive at the pumping rate in

gallons per minute (gpm).

DRAW DOWN ÷ CYCLE TIME x 60 = PUMPING RATE

Locate Water Conditioning Equipment Correctly

Select the location of your filter tank with care. Various conditions which contribute to proper location are as follows:

1. Locate as close as possible to the water supply source.

2. Locate as close as possible to a floor or laundry tub drain.

3. Locate in correct relationship to other water conditioning equipment (see Typical Installations, Page 4).

4. Filter and softeners should be located in the supply line before the water heater. Temperatures above 110° F (43°C) will damage the equipment and void the warranty.

5. Do not install a filter or softener in a location where freezing temperatures occur. Freezing may cause permanent damage to the equipment and void the warranty.

6. Allow sufficient space around the unit for easy servicing.

7. If your water source is a community or public water supply or if you wish to bypass water used for a geothermal heat pump, lawn sprinklers, out buildings or other high demand applications, refer to installation instructions.

The Importance of Your Pressure Tank

The pressure tank found on private well systems becomes an integral part of the filter system by providing necessary mixing and "contact time" to the "air-injected" water. While the iron filter will perform better on a standard air-to-water pressure tank, it will perform satisfactorily on a captive air (bladder) pressure tank. The bladder tank requires more careful adjustment of the Mazzei injector and careful location of the air relief valve.

If cycle time on the pumping system is less than 30 seconds and under severe operating conditions (low pH, high iron, manganese and small concentrations of hydrogen sulfide), a standard air-to-water pressure tank with an air relief valve must be used (if a bladder tank is already in place, do not remove it, install the air-to-water pressure tank between the Mazzei injector and the bladder tank).

NOTE: If your pressure tank (or any part of your water system) is not functioning properly, corrective action must be taken before installation of your chemical free iron filter.
