Hague Quality Water Intl H2500 用户手册

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 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. 

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 advanced 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. 

Our Reverse Osmosis Drinking Water appliances contain replaceable treatment components, critical for the effective reduction of Total Dissolved Solids as well as 
inorganic contaminants. Each appliance will have some or all of the following replacement service components: Sediment pre-filter, sediment/carbon block pre-filter 
( H3500 only ), activated carbon pre-filter, prolonged contact filter, activated carbon post-filter, flow restrictor and the membrane. (Please see replacement element 
diagrams on reverse side.) The life expectancy of these components will vary from one water source to another. Therefore, we recommend that you, the user, have 
the water tested every six months to maintain acceptable water quality. Operational, maintenance and replacement requirements are essential for these appliances 
to perform to specification. To maintain the highest quality water, we recommend draining the storage tank every week. Ask your dealer about maintenance 
programs or monitoring devices for any of our drinking water appliances.
