Performance Data - Whirlpool WHAROS5 Installation And Operation Manual

Reverse Osmosis Filter System - Model WHAROS5
IMPORTANT NOTICE: Read this performance data and compare the capabilities of this unit with your actual water
treatment needs. It is recommended that, before purchasing a water treatment 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 not use where water 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
water that may contain filterable cysts. This system has been tested for the treatment of water containing
pentavalent arsenic (also known as As (V), As (+5), or arsenate) at concentrations of 0.30 mg/L or less. This system
reduces pentavalent arsenic, but may not reduce other forms of arsenic. This system shall be used on water supplies
containing a detectable free chlorine residual at the system inlet or on water supplies that have been demonstrated
to contain only pentavalent arsenic. Treatment with chloramine (combined chlorine) is not sufficient to ensure
complete conversion of trivalent arsenic to pentavalent arsenic. Please see the Arsenic Facts section on page 8 for
further information. While testing was performed under standard laboratory conditions, actual performance of this
system may vary based on local water conditions. Some or all of the contaminants reduced by this unit may not be
in your water supply. See elsewhere in this owner's manual for further instructions on filter replacement, system
installation, operating procedures, and warranty. The maintenance instructions must be followed for the product to
perform as indicated below.
This 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 faucet indicator monitors the length of
time the filter has been installed and will flash amber continuously; indicating the filters and battery need to be
replaced. This system has been tested according to NSF/ANSI 58 and 42 for reduction of substances listed below.
The concentration of the indicated substances in water entering the systems were reduced to a concentration less
than or equal to the permissible limit for water leaving the system, as specified in NSF/ANSI 58. The testing was
performed using spiked chlorine free deionized water with ≤1 NTU turbidity, 7.5 ± 0.5 pH, 25 ±1°C, and 1μS/cm
conductivity.
Replacement filter prices may vary. Estimated costs of replacement filter elements (part number WHEERF), or
replacement membranes (part number WHEERM), range from $39 to $59.
* Grains per gallon.
** A carbon prefilter is part of this system to protect the reverse osmosis membrane from
deterioration should there be chlorine in the supply water. This reverse osmosis system
contains a replaceable treatment component critical for effective reduction of TDS. The
product water shall be tested periodically to verify that the system is performing satisfactorily.
