R.O. Membrane Information
Type: T.F.C.-24
Rated Membrane Production1: produces 24 +/- 4 gpd (76-106 lpd)
Rated Membrane TDS Reduction1: 95% minimum

1Measured at Industry Standard condition of 65 psig, 77°F (25°C), 500 mg/L TDS and discharging to atmosphere.

NOTE: Actual system production and contaminant reduction will depend on water temperature and pressure, TDS level, membrane variation and usage pattern.

Conditions of Use
Water Supply: Potable chlorinated or non-chlorinated
Water Pressure: 40-100 psig
Water Temperature: 40-100°F (4-38°C)
Water Supply Parameters
Hardness: less than 170 mg/L or softened
Iron: less than 0.1 mg/L
Manganese: less than 0.05 mg/L
Hydrogen Sulphide: None
pH Range: 6-9
TDS Level: no more than 1500 mg/L
Chlorine: see note below
Bacteria: water source must be potable

Chlorine will damage a TFC membrane. The Carbon Block Pre-filter will remove chlorine from the incoming water.

Carbon Filter to be changed every six months, more often if water contains more than 1ppm chlorine.
Sediment Pre-filter to be changed every six months.
Membrane to be changed at least every two years.

Do not use with water that is microbiologically unsafe or of unknown quality; without adequate disinfection before or after the system.
