1
H3000 and H3500 are certified by WQA to NSF/ANSI 58 for the specific performance
claims as verified and substantiated by the test data. These are the only units certified
by WQA.
2
Product output is measured to atmosphere with feed water of 77 degrees F, 60 PSIG
and 360 ppm TDS.
3
WQA production is measured against a pressure tank @ 5 psi backpressure,
77 degrees F, 50 PSIG and 750 mg/L ± 40 mg/L TDS,
1 NTU turbidity 7.5 ± 0.5 pH, 1 US/cm.
4
LC50P and LC100P use dual function prefilter for chlorine taste and odor removal.
Note: Actual production rates may vary depending on water temperature, pressure, TDS
level and membrane type.
5
Efficiency Rating means the percentage of the influent water to the system that is
available to the user as reverse osmosis treated water under operating conditions that
approximate typical daily usage.
6
Recovery Rating means the percentage of the influent water to the membrane portion of
the system that is available to the user as reverse osmosis treated water when the
system is operating without a storage tank or when the storage tank is bypassed.
