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 recommended 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.
