Introduction
Blake Water Solutions’ Specialist Series™ point-of-entry (POE) Aerating Iron Oxidizer (AIO) filter systems function as a
regenerable water treatment unit utilizing oxygen instead of potentially harmful chemicals to rejuvenate and enhance the
performance of the selective filtration media. The filtration media provided is specific to the water contaminant or contaminants
that your water treatment specialist has identified.
The AIO system utilizes the Clack WS1EE control valve equipped with air injection capability to remove ferrous (or clear water)
iron, manganese, and sulfur from the water by both oxidation and filtration. During the regeneration cycle, an air bubble is
established in the head space of the filter tank above the media. Then, during service, as untreated water enters the tank, it mixes
with the air. Oxygen present in the air oxidizes some of the iron and managese that are present in the water, causing them to
precipitate into particles which become trapped in the filter media. The remaining dissolved iron and manganese precipitate out in
the filter bed as they are oxidized by the catalytic reactions occurring on the media surface.
Unlike other iron filter alternatives, the Clack WS1EE AIO technology is designed for use in a single tank / valve system
configuration, reducing both installation and maintenance costs, yet delivering years of trouble-free service. No chemical additives
or air compressors are required for operation or regeneration with the Clack WS1EE AIO’s unique and advanced design.
Do not install this system if methane is present in the water - DANGEROUS DEADLY GAS CAN ACCUMULATE
This system is not intended to be used for treating water that is microbiologically
unsafe or of unknown quality without adequate disinfection before or after the system.
Installation Requirements
WATER PRESSURE: A least 30 psi of water pressure (2.7bar) is required for the injector to draw air and operate effectively.
CAUTION: Water pressure must not exceed 80psi (5.5 bars), water temperature is not to exceed 110°F (43°C), and the unit cannot
be subjected to freezing conditions.
NOTE: Due to the air pocket, exceeding 80PSI will adversely impact performance.
ELECTRICAL FACILITIES: An uninterrupted 120 VAC supply is required. The valve is supplied with a 12 VAC transformer.
Please make sure your voltage supply is compatible with your unit before installation.
EXISTING PLUMBING: Condition of existing plumbing should be free from scale and iron buildup. Piping that is built up heavily
with scale and/or iron should be replaced.
LOCATION OF FILTER AND DRAIN: The filter should be located close to a drain to prevent air breaks and back flow.
DRAIN AIR GAP: Always provide the proper air gap distance of two drain pipe diameters.
