PurelyEZ Manual Introduction
The PurelyEZ RO System conforms to NSF/ANSI Standard 58
for performance claims as verified and sustained by test data. All pre and
post filtration demands were removed prior to contaminant reduction
performance testing by the Water Quality Association laboratory.
The PurelyEZ reverse osmosis drinking water system is designed for easy installation and maintenance. You will insure a successful
installation as well as reliable operation by carefully reading this manual and following the operational guidelines. Please note
that routine maintenance is essential to the longevity and performance of the system. Filters should be changed every six to twelve
months (see below) depending on the quality of the feed water supply.
The PurelyEZ RO installation should comply with all
state and local laws and regulations. Manufacturer recommends a TDS test every six months.
This system is acceptable for
treatment of influent concentrations of no more that 27 mg/L nitrate and 3 mg/L nitrite in combination measured as N and is certified for
nitrate/ nitrite reduction only for water supplies with a pressure of 40 psig or greater. This reverse osmosis system contains a replaceable
component critical to the efficiency of the system. Replacement of the reverse osmosis component should be with one of identical
specifications, as defined by the manufacturer, to assure the same efficiency and contaminant reduction performance.

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 operated without a storage
tank or when the storage tank is bypassed.
Caution:
Do not use this
system where the water is Bacteriologically unsafe or of unknown quality.
This system is for use on potable water only. Source- water exceeding the chemical parameters
(listed above) requires pretreatment.
