GENERAL USE
CONDITIONS
Read this Performance Data Sheet and
compare the capabilities of this refrigera-
tor with your actual water treatment
needs.
DO NOT use this product where water
is microbiologically unsafe or of
unknown quality without adequate
disinfection before or after the sys-
tem. Systems certified for cyst reduc-
tion may be used on disinfected water
that may contain filterable cysts.
Use only with cold water supply.
Check for compliance with the state
and local laws and regulations.
The retractable water filtration system
uses a WF50 replacement cartridge.
Timely replacement of filter cartridge is
essential for performance satisfaction
from this filtration system. Please refer to
the applicable section in this Owner’s
Manual for general operation, mainte-
nance requirements and trouble
shooting.
This system has been tested according to
ANSI/NSF 42 and 53 for reduction of the
substances listed below. The concentra-
tion of the indicated substances in water
entering the system was reduced to a
concentration less than or equal to the
permissible limit for water leaving the sys-
tem, as specified in ANSI/NSF 42 and 53.
*Tested using a flow rate of 0.75 GPM (2.83 L/min.) and a maximum pressure of 120 psi (827 kPa) under
standard laboratory conditions, however, actual performance may vary. Health Claim Performance test-
ed and certified by NSF International
** Particle size range classification of test. Particles used were 0.5 –1 microns.
