Do not use with water that is microbiologically unsafe or of unknown quality without adequate disinfection before or after the system WARNING: This system is for use on water supplies that have been treated to public water systems Standards This system has been tested to demonstrate effective reduction of microcystins, however, in the event of reported cyanotoxin event in your water supply, other cyanotoxins may be present in the drinking water which may not be effectively reduced by this system In the event of cyanotoxin notification, follow the recommendations of your drinking water authority The compounds certified under NSF/ANSI 401 have been deemed as incidental contaminants/emerging compounds Incidental contaminants are those compounds that have been detected in drinking water supplies at trace levels While occurring at only trace levels, these compounds can affect the public acceptance/perception of drinking water quality The estimated replacement time of filter, which is consumable part, is not an indication of quality guarantee period, but it means the ideal time of filter replacement Accordingly, the estimated time of filter replacement may be shortened in case it is used in an area of poor water quality The filtration device installation shall comply with applicable state and local regulations The reverse osmosis system contains replaceable treatment component, critical for the effective reduction of total dissolved solids and that product water shall be tested periodically to verify that the system is performing properly The influent water to the system shall include the following characteristics: No organic solvents Chlorine: 2 ppm pH: 7 - 8 Temperature: 41 ºF 95 ºF(5 ºC 35 ºC) Iron: 2 mg/L Turbidity: 1 NTU Hardness: 1000 mg/L This system has been tested for the treatment of water containing pentavalent arsenic (also know as As(V), As(+5), or arsenate) at concentrations of 050 mg/L or less This system reduces pentavalent arsenic, but may not remove other forms of arsenic This system is to be used on water supplies containing detectable free chlorine residual at the system inlet or on water supplies that have been demonstrated to contain only pentavalent arsenic Treatment with chloramines (combined chlorine) is not sufficient to ensure complete conversion of trivalent arsenic to pentavalent arsenic Please see the Arsenic Facts section of this Performance Data Sheet for further information Systems certified for cyst reduction may be used on disinfected water that may contain filterable cysts Efficiency rating means the percentage of the influent water to the system that is available to the user as reverse osmosis treated water under operating conditions that approximate typical daily usage Refer to the owner manual for specific installation instructions, manufacturer limited warranty, user responsibility, and parts and service availability For parts and service availability, please contact your local dealer or Coway Model of Filter Type Usable period (Months) CNFN8S NEO-SENSE FILTER 6 CRMFN8S-20-N2 RO MEMBRANE FILTER 20 CIFN8S-PLUS PLUS INNOSENSE FILTER 18 ARSENIC FACTS Arsenic (abbreviated As) is found naturally in some well water Arsenic in water has no color, taste or odor It must be measured by lab test Public water utilities must have their water tested for arsenic You can get the results from your water utility If you have your own well, you can have the water tested The local health department or the state environmental health agency can provide list of certified labs The cost is typically $15 to $30 Information about arsenic in water can be found on the Internet at the US Environmental Protection Agency website: epa gov/safewater/arsenic html There are two forms of arsenic: pentavalent arsenic (also called As(V), As(+5), and arsenate) and trivalent arsenic (also called As(III), As(+3), and arsenite) In well water, arsenic may be pentavalent, trivalent, or combination of both Special sampling procedures are needed for lab to determine what type and how much of each type of arsenic is in the water Check with the labs in your area to see if they can provide this type of service Reverse osmosis (RO) water treatment systems do not remove trivalent arsenic from water very well RO systems are very effective at removing pentavalent arsenic free chlorine residual will rapidly convert trivalent arsenic to pentavalent arsenic Other water treatment chemicals such as ozone and potassium permanganate will also change trivalent arsenic to pentavalent arsenic combined chlorine residual (also called chloramine) may not convert all the trivalent arsenic If you get your water from public water utility, contact the utility to find out if free chlorine or combined chlorine is used in the water system This system is designed to remove pentavalent arsenic It will not convert trivalent arsenic to pentavalent arsenic The system was tested in lab Under those conditions, the system reduced 050 mg/L pentavalent arsenic to 010 mg/L (ppm) (the USEPA standard for drinking water) or less The performance of the system may be different at your installation Have the treated water tested for arsenic to check if the system is working properly The RO component of system must be replaced every 20 months to ensure the system will continue to remove pentavalent arsenic The component identification and locations where you can purchase the component are listed in the installation/operation manual
