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. 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.

Depending on water chemistry, water temperature, and water pressure Watts Water Quality R.O. 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.
REFER TO OWNER’S INSTALLATION/SERVICE MANUAL FOR FURTHER MAINTENANCE REQUIREMENTS AND WARRANTY
INFORMATION.
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. This system is acceptable for treatment of influent concentrations of no more than 27 mg/L nitrate and 3 mg/L nitrite in combination measured as N and is
certified for nitrite/nitrate reduction only for water supplies with a pressure of 280 kPa (40 psig) or greater. If your water supply is under 40 psi Watts Premier
recomends the use of a RO booster pump for proper operation.
3. Operating Temperature:
Maximum: 100°F (40.5°C)
Minimum: 40° (4.4°)
4. Operating Water Pressure:
Maximum: 100 psi (7.0kg/cm2)
Minimum: 40 psi (2.8kg/cm2)
5. pH
2 to 11
6. No iron present in incoming feed water supply.
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.
