To clean your filter unit, wipe down  
the exterior with a damp cloth. 

Once filters are at 95% capacity (about  
every 6 months), the battery alarm will  
sound and flash red when water is  
flowing and will continue for 15 seconds  
once water is turned off. Change the  
battery every time you replace your filters.  
The battery is included with the filter 
replacement cartridges.

Safeguards

•  Use only cold water with filter.

•  If you experience a hose connection  
  leak, disconnect and re-seat the hose.

Do not use with water that is microbiologically 
unsafe or of unknown water quality without 
adequate disinfection before or after the 
system. Systems certified for cyst reduction 
may be used on disinfected waters that may 
contain filterable cysts.
