System Overview
• Unger nLite HydroPower systems contain mixed bed ion exchange resin to
remove impurities out of ordinary drinking water, commonly referred to as pure
water. Such impurities are referred to as total dissolved solids (TDS) and are
measured in parts per million (ppm). Water is considered 100% demineralized
or pure when its TDS is measured at 0 ppm. The average TDS of drinking water
is 180 ppm. Pure water attracts dirt and impurities from the surface being
cleaned, holding it in solution. Pure water left on the surface will dry to a clean
and spot-free appearance.
• No power is required other than drinking water line
pressure, which typically ranges from 40 to 60 psi.
This enables the system to produce pure water
at up to 1.5 gallons per minute. The production of
pure water is not sensitive to water temperatures.
Unger recommends testing the water supply (TDS)
before working (see page 12 for more information).
• Mixed bed ion exchange resin eventually becomes
exhausted and no longer able to remove impurities.
The nLite HydroPower systems incorporate an
on-board TDS (total dissolved solids) meter. TDS is
a measure of how pure the water is. Water that
contains zero TDS is considered pure water and
ideal for cleaning.
•When TDS levels reach over 10 ppm,
the resin should be replaced. Changing
