EXPLANATION OF SIGNAL WORD CONSEQUENCES
WARNING
Indicates a potentially hazardous situation, which, if not avoided, could result in death or serious
injury and/or property damage.
CAUTION
Indicates a potentially hazardous situation, which, if not avoided, may result in property damage.
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 the 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 certifi ed for cyst reduction may be used on disinfected water that may contain fi lterable cysts. EPA
Establishment #070595-CT-001.
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
system bracket.
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. This system is rated for 2.5 gpm (9.46 lpm) fl ow rate.
• 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. Install only on cold water line. The maximum operating water temperature of this
system is 100°F (38°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 backfl ow 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 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 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 fi ttings are secure and free of leaks.
• The disposable fi lter cartridge MUST be replaced every 6 months, at the rated capacity or sooner if a noticeable reduction in
fl ow rate occurs.
