WARNING

 

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 and 
after the system.

 Systems certified for cyst reduction may be 

used on disinfected water that may contain filterable cysts. 

NOTICE
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.

•  

Do not

 install if water pressure exceeds 120 psi (8.2 bar). 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.

•  

Do not 

install on hot water supply lines. The maximum operating 

water temperature of this filter system is 100º F (38º C).

• 

 Protect filter from freezing. 

Drain filter when temperatures drop 

below 33ºF (0.6ºC).

•  The disposable filter cartridge 

should

 be replaced every 

6

 

months at the rated capacity, or sooner if a noticeable reduction 
in flow rate occurs.

Capacity 300 Gallons (1,135 Liters).
