PRODUCT DATA SHEETS

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-LC400V 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 LC400V, part: 
WAFILTER. 2003 suggested retail price of $39.99 U.S.A./
$59.95 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. Systems certified for cyst reduction may be used 
on disinfected waters that may contain filterable cysts.
