Precautions

WARNING: 

Do not use with water that is microbiologically unsafe or of

unknown quality without adequate disinfection before or after the
system.  

CAUTION:

This filter must be protected from freezing, which can cause cracking
of the filter and water leakage.

CAUTION:

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.

CAUTION:

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. Ask your local water municipality
for a copy of their water analysis, or have your private well tested by a 
reputable water testing lab.

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

recommended that the system be flushed thoroughly. Let water run for 2-3
minutes before using.

• The filter cartridge used with this system has a limited service life. Changes

in taste, odor, color and/or flow of the water being filtered indicate that the 
cartridge should be replaced.

The IC-750 with 750R or 1000R replacement cartridge is Tested and Certified by
NSF International to NSF/ANSI Standard 42 for the aesthetic reduction of Taste
and Odor and Chlorine and Particulate Class I*, Standard 53 for the reduction of
Cysts*, Lead*, Lindane*, Atrazine*, and Turbidity*.

*Applies to 1000R replacement cartridge only.
