This system has been tested according to NSF/ANSI 58 for reduction of the substances 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 installation manual for further information.

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. Testing performed under standard laboratory conditions,

actual performance may vary. Refer to owners 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. Operating Temperature:

Maximum: 100°F (40.5°C)

Minimum: 40° (4.4°)

3. Operating Water Pressure:

Maximum: 100 psi (7.0kg/cm2)

Minimum: 40 psi (2.8kg/cm2)

5. Hardness of more than 10 grains per gallon (170 ppm) may reduce TFM membrane life expectancy.

6. Recommend TDS (Total Dissolved Solids) not to exceed 1800 ppm.
