Precautions

Do not use with water that is microbiologically unsafe

or of unknown 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.

This filter must be protected from freezing, which can

cause cracking of the filter and water leakage.

Because of the product’s limited service life and to prevent

costly repairs or possible water damage, we strongly recommend that

the head of the filter be replaced every ten years. If the head of your

filter has been in use for longer than this period, it should be replaced

immediately. Date the top of any new head to indicate the next recom-

mended replacement date.

Turn off water supply to head without cartridge if it must

be left unattended for an extended period of time.

NOTE:

• For cold water use only.

• Make certain that installation complies with all state and local

laws and regulations.

• The contaminants or other substances removed or reduced by

the selected cartridge are not necessarily in your water.

• After prolonged periods of non-use (such as during a vacation) it

is recommended that the system be flushed thoroughly. Let water

run for 10 minutes before using.

• The filter cartridges used with this system have a limited service

life. Changes in taste, odor, and/or flow of the water being

filtered indicate that the cartridge should be replaced.

The US-EZ-1 is certified by IAPMO R&T to NSF/ANSI

Standard 42 for the aesthetic reduction of Chlorine Taste

and Odor and Nominal Particulate Class III.
