to be used as actual installation instructions.
CAUTION: To reduce the risk associated with property damage due to water leakage:
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 on hot water supply lines. The maximum operating water temper
ture of this filter system is 100°F (38°C).
• Do not install if water pressure exceeds 125 psi (862 kPa). If your water pressure
exceeds 80 psi, 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.
• The disposable filter cartridge must be replaced every 6 months, at the rated
capacity or if a noticeable reduction in flow rate occurs.
• Systems certified for Cyst reduction may be used on disinfected water that may
contain filterable cysts. EPA Establishment No. 070595-CT-001
