Specification guidelines.
The system makes a good supply of drinking water each day.
How much it will make depends primarily on these things...
Feed water pressure limits-pounds per square inch (psi) ...................... 40-!20 °
Feed water temperature limits--minimum/maximum degrees F ............... 40-!00
Maximum Total Dissolved Solids (TDS)--parts per million (ppm) ................ 2000
Naximum water hardness @ 6.9 pH recommended to optimize membrane
life-grains per gallon {gpg) ...................................................... ! 0
For water with hardness greater than !0 groins (at 6.9 pH),the use of a
softener is recommended. Failure to install a water softener will reduce
the life of the Reverse Osmosis membrane. See chart for additional
information on the possible need for a water softener.

a. If housewater pressureis over 80 psi,install a pressurereducing valve in the water supply line.If housewater pressure
is under 40 psi,install a ReverseOsmosisbooster pump (contactyour local plumbingsupply company).
b. Removed(maximumof 2.0ppm) by the ReverseOsmosisprefilter. REGULARHAINTENANCEISREQUIRED. Chlorinewill destroy
the ReverseOsmosismembrane.
C.
Theoretical tank capacity. When tested according to NSF/ANSI Standard 58 at 50 psig inlet pressure, tank capacity is
2.3 gallons.
