Chlorine (Cl
2
) 0.00 mg/l *
Hardness (CaCO
3
) < 350 mg/l
Iron (Fe) < 0.1 mg/l
Manganese (Mn) < 0.05 mg/l
Hydrogen Sulfi de (H
2
S) 0.00 mg/l
* Every system is equipped with our unique twin unidirectional granular activated carbon pre-fi lters to
remove organic contaminants and chlorine.
You can obtain specifi cs about your water supply from either your local water department or a water
testing service. If the parameters of your water do not fall within the specifi ed ranges as noted above,
please contact Pure Water Systems or your local dealer for further options.
Production is rated at optimum temperature of 70° F, 60 PSI, and 500 ppm TDS. Actual production will
vary depending on local temperature, pressure, and TDS level.
Low tap water pressure will reduce the volume and quality of the water produced by your system. In low
pressure situations (<40 PSI, 2.75 bar) BEV values cannot be assured. The addition of a booster pump
(PWS-BP-300) is strongly recommended.
ALWAYS USE COLD WATER—hot water will damage the TFC membrane.
The unit must not be allowed to freeze. Freezing water will expand inside the modules—damaging the
membrane and potentially rupturing the fi lter housings. Damage of this type will void the warranty.
