Nature² Benefits
• The Bactericidal qualities of silver reduce the amount of chlorine required to maintain the
pool. The copper inhibits algae growth.
• By Lowering the output of the chlorine generator, the pool water quality dramatically im-
proves and the life of the electrolytic cell is extended.
The Minerals
• Copper– inhibits algae growth, regularly sold as algaecides
• Silver– known bactericide, used for thousands of years to bacteria in water, milk, and on
skin
• Porous Alumina– releases silver and copper, assists in trapping nuisance metals, algae,
and bacteria
The Facts
• Copper is released into the pool at low levels (.02 - .06 ppm)
• Silver is maintained throughout the cartridge life (6 months at .01 - .05 ppm)
• Minimum pump run time is 6 hours, and can be run up to 24 hours

CHLORINE GENERATION INSTALLATION – PLUMBING
3 Port Cell and Sensor
Preferred Plumbing
The “T” for the Flow/Temp/Salinity Sensor should
be pointed down to prevent air entrapment which
could cause false readings.
3 Port Cell and Sensor
OK Plumbing
The 3 Port Cell can be located so the sensor is
mounted to the side of the cell.
3 Port Cell and Sensor

CHLORINE GENERATION INSTALLATION - CHEMISTRY
START-UP
Before starting a chlorine generator
• Balance the pool water
• Super chlorinate if needed.
• Add a metal remover.
WATER CHEMISTRY
• Free chlorine - 1.0 to 3.0 (Low of .5 is possible with the Nature² Fusion)
• pH - 7.2 to 7.8
• Total Alkalinity - 80 to 120 ppm
• Cyanuric Acid (Stabilizer) - 10 to 100 ppm
• Total Dissolved Solids (TDS) - Less than 2000 ppm.
(Subtract salinity level to arrive at corrected level.)

CHLORINE GENERATION INSTALLATION - CHEMISTRY
SALT
As a general guideline, the purer the salt the better the performance and the longer the “life” of the cell.
Calcium and magnesium are the enemies of the cell and cause scaling, poor performance and short-
ened anode life.
It is recommended to use food grade salt only with the following characteristics:
• Minimum 99.8% pure NaCl
• No added anti-caking agents
• No sodium ferrocyanides (aka - yellow prussiate of soda)
• Non-iodized.

WHAT THE LCD DISPLAY MEANS
50 or 60 - The unit is detecting the electrical supply to optimize the unit settings. 60 cycles power is the
US standard. If the unit detects 60 cycles, it will display the temperature in degrees F. 50 cycles is com-
mon in Europe.
CHLORINE PRODUCTION - displays the current production percentage rate for chlorine.
WAIT - the unit is still testing its diagnostics.
NO FLOW - the unit is still testing its diagnostics, or no water flow is detected.
FLOW - the flow sensor is indicating to the unit it has enough water flow.
LO - indicates the water temperature is less than 51 degrees F.
BO - boost cycle has been activated. Cancel by holding the POOL TEMPERATURE button down for 10
seconds.
EC - the unit is being controlled by an external controller or ORP device.
JA - indicates operation is controlled by a Jandy AquaLink RS or PDA, and is in AUTO mode.
JO - indicates operation is controlled by a Jandy AquaLink RS or PDA, and the system is in SERVICE or
TIMEOUT mode.
JB - indicates operation is controlled by a Jandy AquaLink RS or PDA, and the system is in BOOST
mode.
WHAT THE INDICATOR LIGHTS MEAN
CELL ON - Full power is being sent to the cell.
CELL RESTING - The cell is in the off portion of chlorine production cycle. Cycle time is 30 minutes. As an
example, when the chlorine production rate is set to 50%, full power will be applied to the cell for 15 min-
utes and then no power (CELL RESTING) for the next 15 minutes.
FLOW - The sensor is detecting water flow.
CELL REVERSING - Control switches polarity to the cell every 3 hours to help clean the plates. The cell
will rest for 3 minutes between switching of polarity.
ADD SALT - Salinity level is 2.5 gpl or less. Should be 3.0 to 3.5 gpl.
SERVICE - A service problem has been detected. The display will also show one or two error codes.
POWER ON - Power is being sent to the control and received at the User Interface Board

voltage is coming out of the transformer.

FLOW/TEMP/SALINITY SENSOR
The Sensor determines flow by comparing the temperature differ-
ential between the heated and unheated test pads. Salinity is
measured by the two “silver” test pads. These pads should be
kept clean to insure accuracy.
FLOW/TEMP/SALINITY SENSOR REVISION
Current Revisions are HX19 and JX 11
FLOW/TEMP/SALINITY SENSOR CLEANING
Once per year, or as needed, clean the sensor as follows:
1. Remove Flow/Temp/Salinity Sensor.
2. Brush with a mildly abrasive green fiber household
cleaning pad. Contacts should be clean and bright
when done.
3. Thoroughly rinse the Flow/Temp/Salinity Sensor with
clean tap water. Replace and resume normal operation.
4. Turn power off and back on to re-calibrate and reset
Flow/Temp/Salinity Sensor.
PROBLEMS:
• Failure to shut of power.
• Failure to indicate flow.
• Incorrect salt indications.
CAUSES:
• Broken or damaged wires.
• Calcified sensor(s).
• Failed electrical component.
•System not Bonded.
