WARNING |
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.
To reduce the risk of physical injury:
• Shut off inlet water supply and depressurize system as shown in manual prior to cartridge removal.
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 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 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.
•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.
•Mount system 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.
•SHUT OFF FUEL OR ELECTRIC POWER SUPPLY TO WATER HEATER after water is shut off.
•The disposable filter cartridge MUST be replaced every 12 months, at the rated capacity or sooner if a noticeable reduction in flow rate occurs.
IMPORTANT NOTES
•Failure to follow instructions will void warranty.
•Allow a minimum of 2” (5.1 cm) clear space under filter to facilitate cartridge change.
•Install with the inlet and outlet ports as labeled. Make sure not to reverse connections.
