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

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 micro biologically 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)
4. pH
2 to 11
5. Maximum iron present in incoming feed water supply must be less than 0.2 ppm.
6. Hardness of more than 10 grains per gallon (170 ppm) may reduce membrane life expectancy.
7. Recommend TDS (Total Dissolved Solids) not to exceed 1800 ppm.
