Typical AquaPure Installation With Options

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.

Control Center

 

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 

Flow/Temp/Salinity 

Sensor

 is a backup device only.

Electrolytic Cell   

The electrolytic cell contains bipolar electrodes which perform the 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 control 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.  This does not interrupt the 
production of Chlorine.

Flow/Salinity/Temperature Sensor 

   The Flow/Temp/Salinity Sensor only allows the Cell to operate if 

there is adequate water 

fl

 ow through the Cell.  The salinity portion of the Flow/Temp/

Salinity Sensor detects the level of salt in the pool water.  This salt level is displayed 
in grams per liter (gpl) on the Liquid Crystal Display (LCD) whenever the salinity 
button is pressed.  This eliminates the need for manual pool water salinity testing.  
Pool Temperature is now available on all models by pressing the 

Temperature

 button.

 ATTENTION INSTALLER: 

 Various application notes (more detailed instructions) are 

available from the Dealer covering installation, operation, maintenance, and plumbing 
of the chlorinator system.
