Purenex Multipure Aqua RO System - Manual (Page 3)

Operational Parameters
Operating Temperatures: Maximum 100ºF (37.8ºC) Minimum 40ºF (4.4ºC)
Operating Pressure:
Maximum 100 psi (7.43 g/cm2) Minimum 40 psi (2.8 kg/cm2)
pH Parameters: Maximum 11 Minimum 3
Iron: Maximum 0.2 ppm
TDS (Total Dissolved Solids) < 1800 ppm
Turbidity: <5NTU
Hardness: Recommended hardness not to exceed 10 grains per gallon, or 171 mg/L of
hardness as CaCO3. 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.
Note: The operating pressure in your home should be tested over a 24 hour period
to attain the maximum pressure. If it is above 100 psi then a pressure regu-
lator will be required.
Note: Reverse Osmosis water should not be run through copper tubing as the purity
of the water will leach copper and cause an objectionable taste in water and
cause pin holes to form in tubing. Be sure to follow any state or local regula-
tions
