Acceptance level for this substance is based on percentreduction, rather than maximum effluent concentration.System tested and certified by NSF International against NSF/ANSI Standard42 for the reduction of chlorine taste and odor and particulate reduction, andNSF/ANSI Standard 53 for the reduction of benzene, cyst, lead and mercury.General InformationThis system has been tested according to NSF/ANSI 42 and 53 for reduction of substances listed above. The concen-tration of the indicated substances in water entering the system was reduced to a concentration less than or equal to thepermissible limit for water leaving the system, as specified in NSF/ANSI 42 and 53. The testing was performed usingspiked tap water at a flow rate of 1.85 gallons per minute (7.0 L/min.), pH of 7.5 ± 0.5, pressure of 60 psig, and tempera-ture of 68 ± 5°F.This product is protected by U.S. patent no’s: 6,866,704; 6872.311; 7,276,166; 7,296,691; 7,241,388; 7,287,650;7,566,014; 8,056,733; applicable U.S. patent applications; foreign patents and foreign patent applications.Installation RequirementsPressure Range .....................................30-100 psig (207-689 kPa)Temperature Range .............................................40-100°F (5-38°C)Service Flow Rate............................................1.85 GPM (7.0 LPM)Service Life..............................................2000 gallons (7570 Liters)MaintenanceFilter cartridges should be replaced every 2000 gallons or six months, whichever comes first. Replacement filter priceswill vary. Estimated cost of replacement filter cartridge EPWPRF ranges from $70 to $100.Model EPWPFF Premium Main Faucet Water Filtration SystemIMPORTANT NOTICE: Read this performance data and compare the capabilities of this unit with your actual watertreatment needs. It is recommended that, before purchasing a water treatment unit, you have your water supply tested todetermine your actual water treatment needs. This filter system is designed to be used for the reduction of the perform-ance claims listed below. Do not use where water is microbiologically unsafe or of unknown quality, without adequatedisinfection before or after the system. Systems certified for cyst reduction may be used on disinfected water that maycontain filterable cysts. While testing was performed under standard laboratory conditions, actual performance of thissystem may vary based on local water conditions. Some or all of the contaminants reduced by this unit may not be inyour water supply. See elsewhere in this owner’s manual for further instructions on filter cartridge replacement, systeminstallation, operating procedures, and warranty. The maintenance instructions must be followed for the product to per-form as indicated below.
