INTRODUCTION
The use of a Master and Slave AquaRite+ AU setup allows the system to better meet the chlorine demand requirements
of the pool. It is ideal in pools that exceed 150,000 litres in cool climates and 110,000 litres in tropical climates. By
controlling one AquaRite+ AU unit with another, the first unit acts as the Master unit and is installed with the pH and ORP
Upgrade Kits, while the second unit acts as the Slave unit and will produce chlorine when instructed to by the Master unit.
In instances where the Master unit cannot keep up with the chlorine demand of the pool, it will signal for the Slave
chlorinatior to be turned on once the ORP level falls to 2% below the ORP/Redox set point. The Slave unit will then begin
to produce chlorine until the ORP/Redox set point has been reached.
NOTE: Before installing this product as part of a salt water purification system in a pool or spa using natural stone for coping or for immediately
adjacent patios/decking, a qualified stone installation specialist should be consulted regarding the appropriate type, installation, sealant (if any) and
maintenance of stone used around a saline pool with an electronic chlorine generator in your particular location and circumstances.
NOTE: The use of dry acid (sodium bisulfate) to adjust pool pH is discouraged especially in arid regions where pool water is subject to excessive
evaporation and is not commonly diluted with fresh water. Dry acid can cause a buildup of by-products that can damage your chlorinator cell.

INSTALLATION
Master Unit
The Master unit is to be installed with the pH and ORP Upgrade Kits.
The Slave unit is to be installed next to the Master unit.
When installing a Master and Slave set up, both units must be installed on the same body of water.
They can have separate filtration systems or share a common filter with a singular filtration pump.
Each unit must have its own Flow Switch installed as per the diagrams on pages 5 and 7.

Removing the Dead Front Panel
To access the internal circuity of the AquaRite+ AU, 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:
Remove the six (6) screws fastening the panel to the unit. Once all loose, lift the panel off the unit to access the
PCB.

NOTE - Ensure that only 0.5 mm² to 0.75 mm² double insulated cable is used to bridge between the Master
and Slave units. The Slave unit flow switch cable is to be connected/joined to the bridging cable and
terminals inside the Slave Control unit.
The above diagram is a schematic only, and the flow switch wire is not to be pulled apart into to seperate
single insulated conductors further than what is required to make the joins/connections inside the Slave
unit housing.

Cable Gland Installaon
In order to ensure watertight wire connections to the PCB through the AquaRite+ AU enclosure, wire cables are to be
secured with the black cable glands supplied. The two (2) cable glands supplied with the chlorinator are for the Cell Flow
Switch and any Light connections or Master/Slave requirements.
3.
Tighten the gland with a spanner
whilst still holding the nut to secure
the gland in place.
4.
Pull the cord through the gland
until the intended input point can be
reached. Secure and seal the cord in
place by fastening the domed cap with
a spanner until firm.
1.
Insert the cable into the domed end of
the gland and pull it through.
2.
Hold the nut against the hole on the
inside of the mounting frame. Push
the cable and gland into the hole
whilst simultaneously rotating to
screw the nut on to the thread.

Note: Use the gland location holes in the bottom of the unit before the sides to ensure all cables are pointing downward.
The AquaRite+ AU is to be connected to a GPO with a permanent power supply only.
CAUTION - This circuit must be protected by a residual current device (RCD) with a fixed residual
_________operating current not exceeding 30 mA.

NOTE:
-It is recommended that the salinity level for each unit is calibrated to read the same value to limit confusion.
-The temperature reading on each unit should be calibrated to read the same value to limit confusion. If the
Master unit is controlling a heater, ensure that the heater is not running when calibrating the two temperature
readings to be the same. When the heater will be running there will be a differential reading between the two
units due to the different points of measurement in the plumbing.

2. Set the Slave unit to run in Auto Mode ONLY.
3. If the Master unit is set to operate in Auto, Smart, or Heating

the Master unit.
4. If the Master unit is set to operate in Intelligent mode, set the time
schedule of the Slave unit to turn on at 00:01 and off at 23:59
(In this scenario the Slave unit will run a filter pump if connected,
for 24 hours per day). The reason to have the Slave unit standing by
ready to chlorinate for 24 hours, is because the Intelligent Mode that
the Master unit is running, is based on automatic on and off times
and depending on the water temperature, the run times will vary.

OPERATION CONTINUED
With the Master and Slave units both turned on and operating, the Master unit will be trying to keep the ORP level of the
pool on the set point. If the Master unit cannot keep up with the chlorine demand it will call for the Slave chlorinator to be
turned on by closing the Aux 3 relay once the ORP level reaches 2% below the ORP set point. Once the Aux 3 relay closes,
and if the Flow Switch for the Slave unit is also closed, the Slave unit will begin to produce chlorine.
This is evident because on the Master unit display, there will be an “ON” next to the Redox level, and on the Slave unit the
display will change from a FLOW ALERT to a Polarity Informative Display (Pol 1 or Pol 2) with the actual chlorine production
rate being shown on the display.
Once the ORP/Redox set point has been met on the Master unit, it will then turn off the Slave unit by opening the Aux 3
relay.
The Slave unit is effectively a Master unit just being controlled differently so the chlorine output for this unit can still be
adjusted between 1-30 gr/hr as per the Owner’s Manual supplied with the unit.
If a Master/Slave configuration is being installed on a pool/spa combo; using the Spa Flow Switch on the Master unit will
still allow for the chlorine output to automatically reduce to the set percentage. In this situation the Slave unit would still be
called to come on if the ORP/Redox level fell below 2% of the set point but would only be for a very short period of time.
