Estate 2315225 User Manual

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.
