06/14/11 (Rev. H)72728784Performance Data SheetReverse Osmosis Filter SystemModel WHER25IMPORTANT NOTICE: Read this Performance Data Sheet and compare the capabilities of thisunit with your actual water treatment needs. It is recommended that, before purchasing a watertreatment unit, you have your water supply tested to determine your actual water treatment needs.This filter system is designed to be used for the reduction of the substances listed below. Do notuse where water is microbiologically unsafe or of unknown quality, without adequate disinfectionbefore or after the system. Systems certified for cyst reduction may be used on disinfected waterthat may contain filterable cysts. This system is acceptable for treatment of influent concentrationsof no more than 27 mg/L nitrate and 3 mg/L nitrite in combination measured as N and are certifiedfor nitrate/nitrite reduction only for water supplies with a pressure of 280 kPa (40 psig) or greater.This system has been tested for the treatment of water containing pentavalent arsenic (also knownas As (V), As (+5), or arsenate) at concentrations of 0.30 mg/L or less. This system reducespentavalent arsenic, but may not reduce other forms of arsenic. This system shall be used on watersupplies containing a detectable free chlorine residual at the system inlet or on water supplies thathave been demonstrated to contain only pentavalent arsenic. Treatment with chloramine(combined chlorine) is not sufficient to ensure complete conversion of trivalent arsenic topentavalent arsenic. Please see the Arsenic Facts section of the Performance Data Sheet for furtherinformation. While testing was performed under standard laboratory conditions, actualperformance of this system may vary based on local water conditions. Some or all of thecontaminants reduced by this unit may not be in your water supply. See owner’s manual forfurther instructions on filter replacement, system installation, operating procedures, andwarranty. The maintenance instructions must be followed for the product to perform asindicated below.General InformationThis product is an undercounter system that filters and stores quality drinking water ready for use.It contains a carbon sediment filter, RO membrane, and an activated carbon post filter. The faucetindicator monitors the length of time the filter has been installed and will flash ambercontinuously; indicating the filters and battery need to be replaced. This system has been testedaccording to NSF/ANSI 58 and 42 for reduction of substances listed below. The concentration ofthe indicated substances in water entering the systems were reduced to a concentration less than orequal to the permissible limit for water leaving the system, as specified in NSF/ANSI 58. Thetesting was performed using spiked chlorine free deionized water with ≤1 NTU turbidity, 7.5 ± 0.5pH, 25 ±1°C, and 1μS/cm conductivity.MaintenanceReplacement filter prices may vary. For estimated costs of replacement filter elements partnumber WHEERF or replacement membranes part number WHEERM please call toll free at 1-866-986 3223.Application Specifications For Feed WaterPressure...................................................40-100 psig (2.8-7.0 kg/cm2)Temperature ........................................................... 40-100°F (5-38°C)Maximum TDS Level..........................................................2000 mg/LMaximum Hardness @ 6.9 pH.............................. 10 gpg1 (171 mg/L)Maximum Iron, Manganese, Hyd.

This reverse osmosis system contains areplaceable treatment component critical for effective reduction of TDS. The product water shallbe tested periodically to verify that the system is performing satisfactorily.1
