and use of this system.
To reduce the risk associated with property damage due to water leakage or flooding:
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 100°F
(43.3°C).
Do not install on hot water supply lines. The maximum operating water temperature of
this filter system is 100°F (37.8°C).
If your water pressure exceeds 80 psi (552 kPa), you must install a pressure reducing 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. Contact a plumbing professional if
you are uncertain how to select/install/maintain a thermal expansion device.
Booster Pump: if a booster pump is installed on a water system, you must (a) maintain
and inspect the attached pressure switch regularly in accordance with the booster pump
manufacturer's instructions; and (b) install an appropriate pressure relief valve, and
maintain and inspect the valve regularly.
Do not use a torch or other high temperature sources near filter 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.
Do not install near water pipes which will be in path of a drilling tool when selecting the
position to mount the bracket.
Mount filter 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.
