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 fi lter 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 fi lter 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 qualifi ed 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 qualifi ed installer if you are uncertain how to check for this condition.
• Where a backfl ow prevention device is installed on a water system, a device for controlling pressure due to ther-
mal expansion must be installed.
• Do not use a torch or other high temperature sources near fi lter system, replacement fi lters, plastic fi ttings or
plastic plumbing.
• On plastic fi ttings, never use pipe sealant or pipe dope. Use PTFE thread tape only, pipe dope properties may dete-

• Ensure that the location and fasteners will support the weight of the system when installed and full of water.
• Ensure all tubing and fi ttings are secure and free of leaks.
• Do not install unit if any fi tting collets are missing. Contact 3M if collets are missing from any fi ttings.
• All hydropneumatic tanks must have an appropriate pressure relief valve installed.
• The disposable replacement fi lters must be replaced every 12 months, at the rated capacity or sooner if a notice-
able reduction in fl ow rate occurs.
• The RO membrane module must be replaced every 36 months, at the rated capacity or sooner if a noticeable
reduction in fl ow rate occurs.
• Failure to install or operate your fi lter system in accordance with these use instructions or any
other installation or use instructions accompanying this product may result in product failure and
