Base Grille Water Filtration System
Model WF-NL300/NL300 capacity 300 Gallons (1136 Liters)
Model WF-L500/L500 capacity 500 Gallons (1893 Liters)
This system has been tested according to ANSI/NSF 42/53 for the reduction of the substances listed below. The concentration 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 system, as specified in ANSI/NSF 42/53.
Test Parameters: pH = 7.5 ± 0.5 unless otherwise noted. Flow = 0.5 gpm (1.9 Lpm). Pressure = 60 psig (413.7 kPa). Temp. = 63°F
(17.2°C).
■ It is essential that operational, maintenance, and filter
replacement requirements be carried out for the product to
perform as advertised.
■ Model WF-NL300: The concentration 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 system as specified in ANSI/NSF 42 and 53.
Change cartridge at least every 6 months. Use replacement
cartridge NL 300, part #4396508. 2005 suggested retail price
of $32.99 U.S.A./$44.95 Canada. Prices are subject to change
without notice.
■ Model WF-L500: The concentration 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 system as specified in ANSI/NSF 42 and 53.
The filter monitor system measures the amount of water that
passes through the filter and alerts you to replace the filter.
When 90% of the filter’s rated life is used, the filter indicator
light changes from green to yellow. When 100% of the filter’s
rated life is used, the filter indicator light changes from yellow
to red, and it is recommended that you replace the filter. Use
replacement cartridge L500, part #4396508. 2005 suggested
retail price of $32.99 U.S.A./$44.95 Canada. Prices are
subject to change without notice.
■ The product is for cold water use only.
■ Do not use with water that is microbiologically unsafe or of
unknown quality without adequate disinfection before or after
the system.
■ Refer to the “Assistance or Service” section for parts and
service availability or for the Manufacturer’s name, address
and telephone number.
■ Refer to the “Warranty” section for the Manufacturer’s limited
warranty.
■ Note that while the testing was performed under standard
laboratory conditions, actual performance may vary. Systems
must be installed and operated in accordance with
manufacturer’s recommended procedures and guidelines.
System tested and certified by NSF International against
ANSI/NSF Standard 53 for the reduction of Lead; and
against Standard ANSI/NSF 42 for the reduction of Taste
and Odor, Chlorine Class I.
