Before first use, run cold water for 5 minutes 

 in filtered position. 

During filter flush, it is normal to see cloudy water  and  

hear the sound of water pushing air out of the  filter  

cartridge. Flushing removes any loose materials,   

which is normal.

Prior to each use, run cold water for 5 seconds   

in filtered position to activate filter.
Never run hot water through the filter.

Do not use the water above 100˚F/38˚C as this may damage the filter.  Use cold 

water only.

Change your filter every three months for best performance.

To change the filter or if you need sink space, remove the device from your  faucet 

using the white Quick Release buttons. After each new filter cartridge  is installed, 

run cold water for 5 minutes to flush it.

Clean the exterior of the faucet mount housing with a damp sponge  

or soft cloth.

A mild dishwashing liquid may also be used. Using anything else to clean your 

 faucet mount could result in damage to the unit.
