*Total Dissolved Solids (TDS) measured in Parts Per Million (ppm)/Milligrams per Liter (mg/l).
Please Note: This chart is based upon a start–up of a system when the storage tank is empty, (7 psig/48 kPa precharge).
As the tank fi lls, and backpressure from the tank increases, the gpd/lpd rating will decrease.
IMPORTANT! If the water production rate is within the highlighted area (marked with dotted lines), change the
drain restrictor to a 125 gpd (473 lpd) drain restrictor, color-coded purple.
