EXPLANATION OF SIGNAL WORD CONSEQUENCES
WARNING
CAUTION
CAUTION
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 eye injury while drilling countertop for faucet installations:
• Safety glasses MUST be worn during the sink hole drilling operations.
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 filter from freezing, remove replacement 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 expan-
sion must be installed.
• Do not use a torch or other high temperature sources near filter system, cartridges, 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.
• 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 (waste baskets, etc.);
• 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 collet is missing. Contact 3M if collets are missing from any fittings.
• The disposable replacement filter MUST be replaced every 12 months, at the rated capacity or sooner if a noticeable
reduction in flow rate occurs.
• Failure to follow instructions will void warranty.
• Allow a minimum of 3" (7.6 cm) clear space under filter to facilitate filter change.
• Install with the inlet and outlet ports as labeled. Make sure not to reverse connections.
