3M™Advanced Whole House Filtration System for City Water
To reduce the risk associated with property damage due to water leakage:
• Read and follow Use Instructions before installation and use of this system.
• Before starting installation, shut off main water supply and drain pipes.
• Installation and Use MUST comply with all state and local plumbing codes.
• Protect from freezing, remove filter 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 125 psi (862 kPa). 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.
• Do not install where water hammer conditions may occur. If water hammer conditions exist, you must install a water hammer arrester. Contact
a plumbing professional 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, 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 overtightening 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.
• Ensure all tubing and fittings are secure and free of leaks.
• Shut off fuel or electric power supply to water heater after the water is shut off.
• The disposable replacement filter MUST be replaced every 12 months at the rated capacity or sooner if a noticable reduction in flow rate occurs.

To reduce the risk associated with 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 path of a drilling tool when selecting the position to mount the filter bracket.
To reduce the risk of physical injury:
• Shut off inlet water supply and depressurize system as shown in manual prior to filter removal.
