INTRODUCTION
The ORP Upgrade Kit is an optional accessory to add on to the AquaRite+’s optional pH Upgrade Kit. With the pH Upgrade Kit fitted to the
AquaRite+, it enables the unit to measure the pH level of the water and, if it is above the set point, automatically dose liquid acid to reduce
the pH back to the set point level. Fitting the ORP Upgrade Kit allows the AquaRite+ to then measure the Oxidation Reduction Potential
(ORP or Redox) of the pool/spa water and activate the TurboCell to produce chlorine if the ORP measurement is below the set point.
Measuring the ORP of the water tells us the quality and/or the ability of the chlorine in the water to oxidize unwanted substances in the
water like organic matter and ammonia like compounds. A good starting point for the ORP/Redox set point is explained in the “Setting The
ORP/Redox Level” section on page 8.
When chlorine is produced by the TurboCell at a pH between 7.2 and 7.6, more effective stronger hypochlorous acid (HOCl) is produced
than the less effective weaker hypochlorite ion (HCl-) which is predominantly produced when the pH is over 7.6.
Having a free chlorine water test reading of 2 ppm will have very different ORP/Redox readings depending on what the pH level of the
water is. This is why we explain on page 8 how to get a starting ORP/Redox set point and then make small adjustments of 10mV per day
until the free chlorine level that you want to achieve has been met. As long as the water balance is maintained within the same levels as
when the unit was set, the ORP/Redox set point will need minimal ongoing adjustment.

INSTALLATION
Installing the ORP Probe on the Measuring Chamber
The ORP probe is “wet” packed and protected by a plastic cap. The probe tip must always remain wet. If the probe is allowed to dry, it will be
permanently unusable (not covered by the warranty).
Remove the ORP probe from its plastic protective cap and set the cap aside for later use (winterising). To ensure that the probe remains
wet at all times, fill the measuring chamber with pool water before installing the probe. Apply a length of thread tape to the probe’s threads.
Tighten the probe by hand only. Check that they are watertight at startup. If the probe leaks, do not tighten it further. Remove the probe
and reapply the thread tape, then reinsert the probe.
After installation, check that the probe is constantly in contact with the water in the chamber. The measuring chamber will hold sufficient
water to protect the probe when the pump is off during day to day filtration. If the pump will be off for extended periods of greater than one
week, it is recommended to remove the probe and fill the plastic cap that came with the probe full of water and screw it to the probe for
storage.
Installing the ORP Probe to the AquaRite+
Once the ORP probe is installed correctly in the measuring chamber, it can now be connected to the AquaRite+. The ORP probe needs to
be physically connected to the AquaRite+ and activated by installing the ORP chip set.
Installation should follow these steps:
»Screw the ORP probe into the measuring chamber, alongside the pH probe
»Remove the Dead Front Panel
»Connect the BNC connector on the ORP probe to the ORP/Rx BNC input on the AquaRite+ (Shown above)
»Fit the ORP Chip Set in the terminal labelled rX on the AquaRite+ PCB

Removing the Dead Front Panel
In order to install the ORP chip set to the AquaRite+ circuitry, the Dead Front Panel needs to be carefully removed. Follow the instructions below
to avoid damaging the device and/or its casing.
Caution - Risk of Electric Shock.
Ensure that the unit has been disconnected from all power supplies before removing the Display and Dead
Front Panel. Only a suitably qualified person should remove the Dead Front Panel in accordance with Local/
State/Federal Government regulations and the latest edition of the AS/NZS 3000 Wiring Rules.
Lift Out Interactive Display Module:
Remove display module from its compartment. Use the grooves on either side to pry it out by hand. Take care to not use excessive
force as the module is still wired to the PCB at this stage.
Detach Interactive Display Module:
Turn over the display module and remove the wired plug from the port on the back of the unit. Store the Display Module where it
will not get damaged until it is re-installed.
Unscrew Dead Front Panel:

Fing the ORP Chip Set
Installing the chip set updates the firmware of the AquaRite+, unlocking the ability to control the ORP level of the pool or spa when used
in conjuction with the pH probe and perisaltic pump. Insert the ORP Chip Set into the terminal on the AquaRite+ PCB as shown below
ensuring the pins are facing to the left. After this, access to the PCB is no longer required and the Dead Front Panel can be screwed back
on. Ensure that the gasket is fitted correctly before securing the Dead Front Panel and then reinstall the display module.
WATER CHEMISTRY
Water Balance
The water must be balanced manually BEFORE the device is started up.
The following table summarises the ideal chemical levels recommended by Hayward. Your water should be checked regularly to maintain
these ideal levels in order to minimise surface corrosion, scaling or deterioration and to ensure maximum performance from your
AquaRite+ Chlorinator and accessories.

Seng the ORP/Redox Level
The ORP/Redox level tells you the Oxidation Reduction Potential, i.e. the disinfectant capacity of the water.
Setting the ORP/Redox set point is the last step in setting the AquaRite+.
To find the optimum redox level for your pool, follow the steps below:
1. Start up the pool filtration system (the salt in the pool must be evenly dissolved).
2. Add chlorine to the swimming pool until it reaches 1 to 1.5 ppm. The pH level must be at the set point that you will run the system
____at, between the range of 7.2 and 7.8.
3. After 30 min. Check whether the level of free chlorine in the pool (manual DPD1 test kit) is between 0.8 and 1.0 ppm.
4. Look at the redox value on the screen and enter it as the redox set point.
5. The next day, check the free chlorine levels (manual DPD1 test kit) and the redox level. Increase / reduce the setting in small
increments of 10 mV per day, if required, in order to maintain the desired free chlorine level.
Remember to check the water balance, referring to the Hayward Ideal Chemical Levels (page 7), fortnightly (or sooner if there is a high
bather demand) and adjust the ORP/redox set point according to the steps listed above.
NOTE: The WHO deem drinking water with an ORP reading of 650 mV to be adequately disinfected for consumption. A swimming pool or spa with
an ORP reading of between 700 mV and 720 mV allows for quick disinfection and for breakpoint chlorination. E. Coli is killed in approximately 1 to 2
seconds with an ORP level of 750 mV.

Seling Period
During the first 10-15 days, your system will require more
attention:
»Check that the pH remains at the ideal level (7.2 to 7.8).
»If the pH is exceptionally unstable and uses a lot of acid, check
the Total Alkalinity (see table on page 7).
If the water balance is highly unstable, contact your pool shop or
installer/builder.
REMEMBER:
»That the system needs a certain amount of time to adapt
to your pool and will require additional chemicals during the
first 3-5 days.
»The pool must be regularly maintained and the skimmer
baskets emptied whenever necessary. Also check that your
filter is not clogged.
»Add Water
›It is preferable to add water via the skimmers so that it
passes through the chlorinator cell before entering the
pool. Remember to check the salt level after adding water.
»Dosing Pump
›Regularly check the diluted acid level to ensure that the
pump does not run dry. The dosing pump must be checked
and serviced at regular intervals.
Servicing the Probes
The probes must be clean and free from oil, chemical deposits
and contamination to function properly. As they are in continuous
contact with the water in the pool, the probes may need to be
cleaned weekly or monthly, depending on the number of bathers
and other specific pool characteristics. A slow response, more
frequent pH calibration and inconsistent readings indicate that the
probes need to be cleaned.
To clean the probes, turn off the power to the AquaRite+ and
disconnect from power supply.
Unplug the probe connectors from the control box, unscrew the
probes and carefully remove them from the chamber. Clean the
probe bulb (white ring at the bottom of the body of the probe) with
a soft toothbrush and regular toothpaste.
A household washing-up liquid detergent may also be used to
remove any oil. Rinse with fresh water, replace the thread tape on
the threads, and reinstall the probes.
If the probes continue to give inconsistent readings or require
excessive calibration after they have been cleaned, they should be
replaced.
Probe Storage
The end of the probes must always be in contact with water or they
will dry out. If they are removed from the measuring chamber, they
should be stored in the plastic caps provided (filled with water).
If the storage caps have been misplaced, the probes should be
stored separately in small glass or plastic containers with their
ends immersed in water.
The probes must always be in a frost-free environment.
TROUBLESHOOTING
Alarm AL3: pH Acid Dosing Pump Stopped
»The maximum time allowed to attain the pH set point has been reached. The pH acid dosing pump is stopped to avoid overdosing and
making the water too acidic.
»Please carry out the following checks to avoid equipment failure:
›Check that the container of diluted liquid hydrochloric acid is not empty.
›Check whether the pH read on the display corresponds to the pH in the pool (use a pH test kit). Otherwise, please calibrate the pH
probe or replace it, if necessary.
›Check that the pH pump is running normally.
›To delete this message and reset the dosing, press the “Return” key.
