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 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-NL300: Change cartridge at least every 6 months.

■ Model WF-L500: 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.
2010 suggested retail price of $34.99 U.S.A./$44.95 Canada.
