Figure 1. Typical AquaPure Installation With Options
ATTENTION INSTALLER: Various application notes (more detailed instructions) are
available from the Dealer covering installation, operation, maintenance, and plumbing
of the chlorinator system.
The AquaPure uses a process known as electrolysis to produce sodium hypochlorite (liquid chlorine) from
a low concentration of salt added to the pool water. Hypochlorite kills bacteria, oxidizes organic material,
and kills algae then reverts back to salt. The AquaPure then reuses the salt and the process starts over again.
The AquaPure system is comprised of the following three component parts and an optional pool pump timer.
The control center converts AC electrical current to a low voltage DC current which

is required by the cell to perform the electrolysis. The control center is connected
with the pool circulation pump electrical source so that the electrolytic cell only
operates when the pool pump is on. The fl ow portion of the

The AquaPure electrolytic cell contains bipolar electrodes which perform the
Electrolytic Cell
electrolysis and produce chlorine when energized with DC current. Chlorine
is generated as pool water containing salt passes through the cell. The chlorine
production can be varied by either adjusting the Chlorine Production Level on the
power center or by varying the number of hours the AquaPure is on each day. The
AquaPure automatically cleans the Cell electrodes once every 3 hours by reversing
polarity. This does not interrupt the production of Chlorine.
