WQA–Performance Data Sheet Our H3000 and H3500 Reverse Osmosis Drinking Water Appliances have been
tested and conform to NSF/ANSI Standard 58. The water treatment
performance for specific claims are substantiated and verified by the “Reduction
Performance” test data listed below. The concentration of the indicated
substances in water entering the appliances was reduced to a concentration
less than or equal to permissible limits for water leaving the appliance, as
specified in NSF/ANSI 58. While testing was performed under standard
laboratory conditions actual performance may vary. H3000 and H3500 are
certified by WQA to NSF/ANSI 58.

* This contaminant was tested at 750 mg/L ±40 mg/L TDS.
** This appliance may be used on disinfected water that may contain filterable cysts.
1 This appliance is acceptable for treatment of Nitrate / Nitrite with influent
concentrations of no more than 27 mg/L of nitrate and 3 mg/L of nitrite combined
measured as N and is certified for nitrate/nitrite reduction only for water sources with a
water pressure of 40 psig or greater.
† This appliance has been tested for the treatment of water containing pentavalent
arsenic (also known as As(V), As(+5), or arsenate) at concentrations of 0.30 mg/L or
less. This appliance reduces pentavalent arsenic, but may not remove other forms of
arsenic. This appliance is to be used on water supplies containing a detectable free
chlorine residual at the appliance inlet or on water supplies that have been
demonstrated to contain only pentavalent arsenic. Treatment with chloramine
(combined chlorine) is not sufficient to ensure complete conversion of trivalent arsenic
to pentavalent arsenic. Please see the Arsenic Facts section.
WARNING! These appliances must not be installed where the water source is
microbiologically unsafe or of unknown quality without adequate disinfection before
and/or after the appliance! A water source that is not potable relative to waterborne
pathogens voids the warranty.
Operational maintenance and replacement requirements are essential for these
appliances to perform to specification as advertised.
FACTORS WHICH AFFECT THE LIFETIME AND
PERFORMANCE OF YOUR WATERMAX® RO
1. TYPE OF MEMBRANE: Cellulose Tri-Acetate (CTA): Up to 1,200 PPM TDS with
pressure of at least 40 PSI. Chlorine Tolerant- Some bacteria resistance- 5.0 to 9.0
pH- Excellent production rate- For use only with a chlorinated water supply.
Thin-Film Composite (TFC): Up to 2,000 PPM TDS with pressure of at least 40 PSI.
Not chlorine tolerant- Bacteria resistant-4.0 to 11.0 pH- Most a dvanced thin-film
composite, non-cellulosic- Chemically stable- Highest production rate.
2. SQUARE FEET OF MEMBRANE: The square feet of membrane and the production
of RO water are in direct proportions.
3. WATER PRESSURE: The higher the net pressure across the membrane, the greater
the quantity of RO water. A minimum pressure of 40 PSI is recommended.
4. TOTAL DISSOLVED SOLIDS: The higher the TDS, the lower the production. Each
100 PPM represents about one PSI reduced pressure on the membrane. Thus,
1,000 PPM reduces the effective net pressure by 10 PSI.
5. WATER TEMPERATURE: Colder water results in lower production. Temperatures
above 85 degrees F are to be avoided because of problems with the membrane
support structures and accelerated compaction rates of CTA membranes. TFC may
be used at temperatures up to 113 degrees F.
6. SURFACE COATING OR FOULING: A neglected pre-filter can allow sediment to
accumulate on the cartridge surface and impair the necessary flow of water through
the filter, thus reducing membrane life. Also, salts can precipitate on the membrane,
plugging the pores and channels. A water softener or other types of pre-treatment
installed before the RO appliance significantly reduces this load and extends
membrane life.
