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.
