Because the performance of an RO Membrane is highly dependant upon pressure, temperature and TDS, the following should be used

Industry standards measure R.O. Membranes performance with no backpressure on the product water, at 60 psig (414kPa) and 77°F (25°C). Further conditions on the
above are 250 ppm TDS and a 15% recovery rate. Production rate and TDS reduction figures are for a new Membrane that has been rinsed for 24 hours. The
production rate of a new Membrane can decrease by 10% per year or more, depending upon the scaling and fouling tendencies of the Feed Water.

Measured at 50 psig, 77°±2° F, 717 mg/l TDS per NSF/ANSI Standard 58.

NOTE: Chlorine will damage a TFC Membrane. The Sediment/Carbon Prefilter will remove chlorine from the incoming water. Change filter every 6 months, more often if water
contains more than 1 ppm chlorine.
**DO NOT USE WITH WATER THAT IS MICROBIOLOGICALLY UNSAFE OR OF UNKNOWN QUALITY, WITHOUT ADEQUATE DISINFECTION BEFORE OR AFTER THE SYSTEM
