Arsenic
a
a. This system has been tested for the treatment of water containing pentavalent arsenic (also known as As(V),
As(+5), or arsenate) at concentrations of 0.050 mg/L or less. This system reduces pentavalent arsenic, but
may not remove other forms of arsenic. This system is to be used on water supplies containing a detectable
free-chlorine residual at the system inlet or on water supplies that have been demonstrated to contain only
pentavalent arsenic. Treatment with chloramines (combined chlorine) is not sufficient to ensure complete
conversion of trivalent arsenic to pentavalent arsenic. Please see the Arsenic Facts section of the Merlin
system performance data sheet.

Nitrate/Nitrite (as N)
b
b. This system is acceptable for treatment of influent concentrations of no more than 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 psi (2.76 bar) or greater.
To verify the level of nitrate/nitrite in the product water use the test strips that have been included with the
system. Follow the instrucions that are on the test strip packaging.
The level of nitrate/nitrite in the product water should be within local standards before placing the Merlin system
into operation.
