Berkey PF-2 Instructions

Berkey PF-2™ Fluoride and Arsenic Reduction Elements are designed for use in conjunction with
Elements to adsorb the following unwanted elements found in drinking water:
Black Berkey
®
• Fluoride • Arsenic V and pre oxidized Arsenic III • Other residual heavy metal ions
Technical Information
FLUORIDE: Testing for fluoride was based on 20-30 ppm
of the ion in the influent aqueous solution at a flow rate
of no more than 3 gpm per cubic foot of media. Results of
< 1 ppm of the fluoride ion in the effluent were typical for
the media (>95% reduction). Under optimum conditions,
effluent concentrations of less than 50 ppb were readily
achieved (>99.75% reduction).*
ARSENIC: This product uniquely targets the entire family of
arsenic oxide anions as well as the arsenic cations.*
For maximum removal efficiency, maintain the water being treated
*
between a pH level of 5 and 7. Actual capacity is dependent on the
level of contamination of arsenic, fluoride and other competing
heavy metal ions. Unusually high levels of these contaminants may
reduce the capacity and efficiency of the elements.
Element Replacement
Under normal conditions it is recommended that each set of
two Berkey PF-2™ Fluoride and Arsenic Reduction Elements
be replaced after 1,000 gallons. (The Berkey Light® system is
about 2.75 gallons, therefore the Berkey PF-2™ Fluoride and
Arsenic Reduction Elements should be replaced after 363 refills.
If the system is refilled about one time per day, the Berkey PF-
2™ Fluoride and Arsenic Reduction Elements should be replaced
annually, if the system is refilled about twice per day, the Berkey
PF-2™ Fluoride and Arsenic Reduction Elements should be
replaced about every six months).
Caution! Elements must be purged prior to use.
Do not install before reading installation procedures. Do not screw on the Berkey PF-2™
Fluoride and Arsenic Reduction Elements more than eight revolutions.
