• 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 cartridge when temperatures are expected to drop below 40° F (4.4° 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 125 psi (689 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.
• Do not use a torch or other high temperature sources near fi lter system, cartridges, 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 deteriorate plastic.
• Take care when using pliers or pipe wrenches to tighten plastic fi ttings, 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 fi lter 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 fi ttings are secure and free of leaks.
