PERFORMANCE DATA SHEET
Base Grille Water Filtration System
Model WF-NL240/NL240 Capacity 240 Gallons (908 Liters)
Model WF-L400/L400 Capacity 400 Gallons (1514 Liters
))
This system has been tested according to NSF/ANSI Standards 42 and 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 NSF/ANSI Standards 42 and 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-NL240: Change cartridge at least every 6 months.
Use replacement cartridge NL240, part #4396508.
2008 suggested retail price of $32.99 U.S.A./$44.95 Canada.
Prices are subject to change without notice.
Model WF-L400: 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 L400, part #4396508. 2008 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.
■ Note that while the testing was performed under standard
laboratory conditions, actual performance may vary.
