To reduce the risk associated with choking:
• Do not allow children under 3 years of age to have access to small parts during the installation of this product.
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. Systems certified for cyst reduction may be used on disinfected water that may contain filterable cysts. EPA Establishment # 070595-CT-001
To reduce the risk associated with a hazardous voltage due to an installer drilling through existing electric wiring or water pipes in the area of installation:
•Do not install near electric wiring or piping which may be in the path of a drilling tool when selecting the position to mount the filter bracket.
To reduce the risk of physical injury:
•All hydro-pneumatic pressurized tanks must have an appropriate pressure relief valve installed.
•Shut off inlet water supply and depressurize system as shown in manual prior to filter removal.
To reduce the risk associated with irritation from Sodium Metabisulfite during installation:
•Sodium Metabisulfite (CAS 007681-57-4) is used in a 1% sanitizer solution within the reverse osmosis membrane.
•Do not put this system into service before the RO tank is flushed as specified in the installation instructions. Wear eye and face protection during installation.
•To request an MSDS relating to this product, call 203-238-8965 or visit the web at http://solutions.3m.com/wps/ portal/3m/en_us/MSDS (click MSDS search). For emergencies, call 800-364-3577 or 651-737-6501 (24 hours).
To reduce the risk associated with eye, skin and respiratory and digestive tract burns from Calcium Hypochlorite during installation:

CAUTION
To reduce the risk associated with property damage due to water leakage:
•Read and follow Use Instructions before installation and use of this system.
•Installation and Use MUST comply with all state and local plumbing codes.
•Protect from freezing, remove filter cartridge when temperatures are expected to drop below 40° F (4.4° C).
•Do not install systems in areas where ambient temperatures may go above 110° F (43.3° C).
•Do not install on hot water supply lines. The maximum operating water temperature of this filter system is 100°F (37.8°C).
•Do not install if water pressure exceeds 100 psi (689 kPa). If your water pressure exceeds 80 psi, you must install a pressure limiting valve. Contact a professional qualified installer if you are uncertain how to check your water pressure.
•Do not install where water hammer conditions may occur. If water hammer conditions exist you must install a water hammer arrester. Contact a professional qualified installer if you are uncertain how to check for this condition.
•Where a backflow prevention device is installed on a water system, a device for controlling pressure due to thermal expansion must be installed.
•Do not use a torch or other high temperature sources near filter system, replacement filters, plastic fittings or plastic plumbing.
•On plastic fittings, never use pipe sealant or pipe dope. Use PTFE thread tape only, pipe dope properties may deteriorate plastic.
•Take care when using pliers or pipe wrenches to tighten plastic fittings, as damage may occur if over tightening occurs.
•Do not install in direct sunlight or outdoors.
•Do not install near water pipes which will be in path of a drilling tool when selecting the position to mount the bracket.
•Mount filter in such a position as to prevent it from being struck by other items used in the area of installation.
•Ensure that the location and fasteners will support the weight of the system when installed and full of water.
•Ensure all tubing and fittings are secure and free of leaks.
•Do not install unit if any fitting collets are missing. Contact 3M if collets are missing from any fittings.
•All hydro-pneumatic tanks must have an appropriate pressure relief valve installed.
•The disposable replacement filters must be replaced every 12 months, at the rated capacity or sooner if a noticeable reduction in flow rate occurs.
•The RO membrane module must be replaced every 36 months, at the rated capacity or sooner if a noticeable reduction in flow rate occurs.
•Failure to install or operate your filter system in accordance with these use instructions or any other installation or use instructions accompanying this product may result in product failure and property damage, including water leakage and will void warranty.
