How Your Appliance Works, Cont.
Second Stage—The Reverse Osmosis Membrane
The semi-permeable RO membrane separates the majority of the remaining suspended solids and most of the
dissolved solids from the water molecules. These separated impurities are then washed down the drain.
Maintenance
The RO membrane is critical for effective reduction of total dissolved solids. The product water should be tested
periodically to verify that the appliance is performing satisfactorily. The RO membrane should be changed when
it rejects less than 75% of the dissolved solids. A noticeable change in water quality and taste may occur and
indicates that a change is needed. Consult your Hague dealer for additional monitoring devices or water check
programs.

membrane.
Third Stage—Carbon Post-Filter
The Activated Carbon Post-Filter is the final stage of filtration. It reduces tastes, odors, and aesthetic chlorine.
Maintenance
Replace the Carbon Post-Filter at least once a year.
Note: The performance of the Carbon Post-Filter has not been tested or certified by WQA.
Getting Maximum Efficiency From the Appliance
This appliance should be used only with potable water. It contains replaceable components critical to its
efficiency. Replacement of the components should be with ones of identical specifications, as defined by
Hague, to assure the same efficiency and contaminant reduction performance. See Performance Data Sheet.
