While testing was performed under standard laboratory conditions, actual performance may vary

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:

3. Operating Water Pressure:

4. pH

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.

RECOMMENDED REPLACEMENT PARTS AND CHANGE INTERVALS:

Depending on incoming feed water conditions replacement time frame may vary.

This system has been tested according to NSF/ANSI 58 for reduction of the substances listed below. Conforms to NSF/ANSI 58 for TDS, Cyst reduction and

Nitrate/Nitrite claims as verified and substantiated by test data. 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.

Depending on water chemistry, water temperature, and water pressure, 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.

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 nitrate/nitrite reduction only for water supplies with a pressure of 280 kPa (40 psig) or greater .
