SECTION 1: BEFORE INSTALLATION

Inspecting And Handling Your Filter System:

Inspect the equipment for shipping damage. If damaged, notify the transportation company and request a damage inspection.

Handle the ﬁ lter with care. Damage can occur if dropped or set on sharp, uneven projections on the ﬂ oor. Do not turn the ﬁ lter upside down. Installation must comply with state and local laws and regulations.

Titanium Oxide

Titanium Oxide ﬁ lter media is used to reduce heavy metals in water. It is manufactured as a granular material, is white in color and shipped dry. Titanium Oxide has the ability to reduce Arsenic Arsenate and Arsenite (otherwise referred to as AS (V) and AS (III), if applied and installed properly. The material is sold in cubic foot equivalent quantities for use in backwashing vessels and performs its task by adsorption. Adsorption is performed as the water passes through the ﬁ lter medium in the pressure vessel and the Arsenic is attracted to the media. Once adsorption takes place, the Arsenic is permanently retained by the Titanium Oxide granules. Occasional backwashing of the ﬁ lter will prevent channeling of the ﬁ lter media and wash away any sediment and color to a waste drain while not reducing any Arsenic from the Titanium Oxide. This will help provide better quality water and help extend the life of the ﬁ lter. The life of this ﬁ lter medium can vary depending on the amount of other heavy metals in the water.

IMPORTANT NOTE

Have the water tested thoroughly prior to the installation of this ﬁ lter system.

Test of the following constituents are recommended prior to installation, but are not limited to the following.

1. Arsenate (AS V) 7. Tannins 13. Selenium

2. Arsenite (AS III) 8. Total Dissolved Solids 14. Vanadium

3. Total Hardness 9. Hydrogen Sulﬁ de Gas 15. Cadmium

4. Total Iron 10. Silica 16. Phosphates

5. Manganese 11. Zinc

6. pH 12. Lead

Titanium Oxide has the ability to treat thousands of gallons of water prior to the need for replacement. Under normal household applications it could last several years before the need to replace it. Only testing the ﬁ nished water will determine when it is time to change out the ﬁ lter media bed. The water should be tested at six (6) month intervals to conﬁ rm there is a reduction of Arsenic in the treated water. The target level of Arsenic reduction in the treated water is less than 10 ppb, which is the USEPA maximum contaminant level (mcl). Changing of the Titanium Oxide ﬁ lter media should take place when test results shows greater than 10 ppb in the treated water. Dispose of exhausted Titanium Oxide in accordance with your state and local ordinances and regulations.

One can expect the useful life of Titanium Oxide to vary from various aspects. It should be understood that the higher the Arsenic concentration the shorter the life one could expect from the Titanium Oxide. The life expectancy can vary depending on the amount of other heavy metals that would compete for sites of the Titanium Oxide media, the amount of water being treated, and how well the ﬁ lter unit is backwashed. Backwashing requirements are driven by a pressure drop. Usually backwashing once every 30 days is sufﬁ cient. The ﬁ ltered Arsenic cannot leach from the Titanium Oxide

Analysis of your Water

It is extremely important to have your water tested for the following items prior to installation of this ﬁ lter into your home. Record your results below for future reference:

Constituent Maximum Contaminant Allowed per EPA Result

Hardness (gpg) 100 ppm

Total Iron (ppm) 0.3

Manganese (ppm) 0.05

pH (units) 6.8 - 8.5

Tannins (ppm) 0.5

Total Dissolved Solids (ppm) 500

Copper (ppm) 1.0

Hydrogen Sulﬁ de (ppm)* <0.1

Total Arsenic (ppb) Arsenite (AS III) Arsenite (AS V)

* Note: Hydrogen Sulﬁ de gas (H2S) must be checked and tested prior to installation of an Arsenic Reduction Filter System For accuracy, the sample must be drawn with the

well pump RUNNING and the test be completed within ONE (1) minute after the sample is drawn from the water system.

** Suggested upper limit. Please contact Technical Services for additional information.

Other heavy metals such as lead, mercury, copper, cadmium and zinc may also be reduced in your water by the Arsenic Reduction Filter System and will reduce the life of your media. In addition, pH, silica and phosphates may also affect adhesion performance. Testing your treated water is the only effective way to know when it is time to replace your media. 3M Puriﬁ cation Inc. recommends you do this every six months.

Check Your Pumping Rate and Water Pressure:

Two water system conditions must be checked carefully to avoid unsatisfactory operation or equipment damage:

1) MINIMUM water pressure required at the water inlet is 20 psi (138 kPa). IF WATER PRESSURE IS OVER 80 psi (552 kPa), A PRESSURE REDUCING VALVE MUST BE INSTALLED IN THE WATER SUPPLY LINE AHEAD OF THE SYSTEM.

CAUTION

To reduce the risk associated with property damage due to water leakage:

• Do not install if water pressure exceeds 100 psi. If your water pressure exceeds 80 psi (552 kPa), you must install a pressure limiting valve. Contact a plumbing professional if you are uncertain how to check your water pressure.

NOTE: If you have a municipal or a 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:

Water Pressure:

Low psi High psi

CAUTION

To reduce the risk associated with property damage due to water leakage:

• Do not install system where water lines could be subjected to vacuum conditions without appropriate measures for vacuum prevention.

The installer should take appropriate measures if there is the possibility a vacuum may occur. This would include the installation of an ap-

propriate device in the supply line to the system, i.e., a vacuum breaker or backﬂ ow prevention device. Vacuum damage voids the factory warranty.

2) The pumping rate of your well must be sufﬁ cient for satisfactory operation and BACKWASHING of the system. (See EQUIPMENT SPECIFICA-

TIONS AND OPERATING DATA, Section 5)

Locate Water Conditioning Equipment Correctly:

Select the location of your Arsenic Reduction Filter System with care. Various conditions which contribute to proper location are as follows:

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

2) Locate as close as possible to a drain.

3) Locate in correct relationship to other water conditioning equipment (Figure 1, page 2-1).

4) Locate the Arsenic Reduction Filter System in the supply line BEFORE the water heater. Temperatures above 110°F (43.3°C) will damage the Arsenic Reduction Filter System and void the factory warranty.

5) DO NOT install the Arsenic Reduction Filter System in a location where freezing temperatures occur. Freezing may cause permanent damage and will also void the factory warranty.

6) Allow sufﬁ cient space around the installation for easy servicing.

7) Provide a non-switched 110V, 60Hz (220V, 50Hz for speciﬁ ed systems) power source for the control valve.

WARNING

To reduce the risk associated with ingestion of contaminants:

• Do not use with water that is microbiologically unsafe or of unknown quality without adequate disinfection before or after the system.

CAUTION

To reduce the risk associated with property damage due to water leakage:

• Protect from freezing, relieve pressure and drain system when temperatures are expected to drop below 33°F (0.6°C).

• Do not install on hot water supply lines. The maximum operating water temperature of this ﬁ lter system is 110°F (43.3°C).

Facts to Remember While Planning Your Installation:

1) All installation procedures MUST conform to local and state plumbing codes.

2) If lawn sprinkling, a swimming pool, or geothermal heating/cooling or water for other devices/activities are to be treated by the Arsenic Reduction Filter System, a larger model MUST be selected to accommodate the higher ﬂ ow rate plus the backwashing requirements of the Arsenic Reduction Filter System. Consult our Customer Service Department at 1-866-990-9785 for alternative instructions if the pumping rate is insufﬁ cient.

3) Remember that the Arsenic Reduction Filter System INLET is attached to the pipe that supplies water (i.e. runs to the pump) and the OUTLET is the line that runs toward the water heater.

CAUTION

To reduce the risk associated with property damage due to plugged water lines:

• Pay particular attention to correct orientation of control valve. Water ﬂ ow should match arrow on control valve. The Inlet and Outlet of other water treatment equipment products will vary depending on the control valve brand used.

4) Before commencing the installation it is advisable to study the existing piping system and to determine the size, number and type of ﬁ ttings required.

WARNING

To reduce the risk associated with a hazardous voltage:

5) Sweep the ﬂ oor to eliminate objects that could pierce the media tank.
