Operational Parameters
Operating Temperatures: Maximum 100°F (37.8°C) Minimum 40°F (4.4°C)
Operating Pressure: Maximum 85 psi (6.0 kg/cm
2
) Minimum 40 psi (2.80 kg/cm
2
)
pH Parameters: Maximum 11 Minimum 2
Iron: Maximum 0.2 ppm
TDS (Total Dissolved Solids) < 1800 ppm
Turbidity < 5 NTU
Hardness: Recommended hardness not to exceed 10 grains per gallon, or 170ppm. System will
operate with hardness over 10 grains but the membrane life may be shortened. Addition of a water
softener may lengthen the membrane life.
Copper Tubing: Reverse Osmosis water should not be run through copper tubing as the purity of
the water will leach copper causing an objectional taste in water and pin holes may form in the tubing.
Watts supplies speciality lters (part number 107008) that can be used if copper tubing follows the
Reverse Osmosis unit. Be sure to follow any state or local regulations during installation.
Water Pressure: The operating water pressure in your home should be tested over a 24 hour
period to attain the maximum pressure. If the incoming water pressure is above 85 psi a pressure
regulator is recommended and if over 100 psi then a pressure regulator is required.
