3-Stage Reverse Osmosis System - H2O-DWRO300
GENERAL USE CONDITIONS
1. System to be used with municipal or well water sources
treated and tested on regular basis to insure bacteriological
safe quality. DO NOT use with water that is microbiologically
unsafe or unknown quality without adequate disinfection
before and after the system. Systems certified for cyst
reduction may be used on disinfected water that may contain
filterable cysts.
2: Operating Temperature: Maximum: 100°F (37.7°C) Minimum
40° F (4.4° C)
3: Operating Water Pressure: Maximum 100-psi (690 kPa)
Minimum: 35 psi (341 kPa)
4. Rated service flow: 0.5 GPM
5. pH 2 to 11
6. Maximum Iron present in incoming water supply must be less
than 0.2 ppm.
7. Hardness of more than 10 grains per gallon (170 ppm) may
reduce RO membrane life expectancy.
8. Recommend TDS (Total Dissolved Solids) not to exceed
1800 ppm.
This system has been tested according to NSF/ANSI 58 for 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 NSF/ANSI 58 and 42. 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
remove other forms of arsenic. This system is to 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
of the Performance Data Sheet for further information.
While testing was performed under standard laboratory conditions, actual performance may vary. Depending on water chemistry, water
temperature, and water pressure the systems production and performance will vary. 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. Recovery rating means the percentage of the influent water to the membrane portion of the system that is available
to the user as reverse osmosis treated water when the system is operated without a storage tank or when the storage tank is bypassed.
There is an average of 4 gallons of reject water for every 1 gallon of product water produced.
