The product shall be installed according to AS/NZS 3000 wiring rules. It shall be installed outside the pool zone. To reduce the risk of accidents or incidents, service on the unit should only be performed by a qualified pool service professional and not operated by children under 18 years of age.

WHEN MIXING ACID WITH WATER:
ALWAYS ADD ACID TO WATER. NEVER ADD WATER TO ACID.

DO NOT PLUG UNIT IN IF CARTON HAS BEEN WET.

GAS BUILD-UP CAN OCCUR WITH IMPROPER WIRING.

To reduce the risk of personal injury, the Control Unit is designed so that the OXI Cell and ION Rods will only receive power when the pool pump is on. Otherwise possible gas build-up can occur. If the pump is not installed to the AC Socket (pump outlet) on the Control Unit, the installer MUST ensure that the OXI Cell and ION Rods are never energised when the pool pump is OFF or water is not flowing through the unit.

Before you start:

• We DO NOT recommend the use of valves on the inlet or outlet of the Cell Housing. If you do use a valve then it is important to ensure that the valve cannot deadhead (lock closed) while the pump is running. It is the installer’s responsibility to ensure some form of flow control is installed in this instance and it disables the pump.
• ALWAYS ensure that pipe work and equipment do not allow gases generated to collect and build up in any part of the installation.
• DO NOT apply priming fluid to the Cell Housing, it is not needed and may react with the plastic.

INSTALLATION | CELL HOUSING

Before you start:

• A Venturi Pipe is incorporated within the Cell Housing designed to eliminate any possible gas build up, although it is always recommended to ensure proper installation to eliminate this from happening.
• The Cell Housing must be installed in the RETURN pipework to the pool. It must always be installed AFTER the filter, gas heater, solar heating or heat pump

INSTALLATION STEPS (Refer to Typical System Installation diagram)

STEP 1 Connect the Cell Housing horizontally (A or B) in the return line to the pool (use Reducing Bushes supplied if using 40mm PVC pipe) using high pressure PVC glue. The Cell Housing can be mounted vertically (C) but provision must be made for a gas trap.

STEP 2 Check that the O-ring is clean, greased with silicone grease ( DO NOT use petroleum based jelly) and securely located in the Cell Housing.

STEP 3 Fit the OXI Cell and ensure the Locking Ring is firmly tightened by hand.
DO NOT USE A TOOL TO TIGHTEN

INSTALLATION | CONTROL UNIT

Before you start:

• The Control Unit has an Ingress Protection Rating of IP34 enabling it to be installed outdoors. Regulations require that the Control Unit shall be installed outside the pool zone. The Control Unit shall be installed according to AS/NZS 3000 wiring rules.
• The Control Unit should be installed in a well ventilated position, ideally away from sunlight and rain to prolong life and at least 1m above ground to prevent run off water entry.
• Ensure that the Control Unit is not stored near chemicals, fertilisers or in a closed unventilated shed with similar products as the fumes will cause excessive corrosion and damage to the internals of the Control Unit and may void warranty. When mounting the Control Unit on a post it is recommended to install a flat panel of at least the same size or larger to act as a waterproof backing plate.
• Mounting the Control Unit horizontally or leaving it on the ground will void all warranty.
• The Control Unit should be mounted no further than 1.5 metres from the Cell Housing for ease of operation.
• The pump rating must NOT exceed 8 Amps.

INSTALLATION STEPS (Refer to Typical System Installation diagram)

STEP 1 Attach Wall Mounting Bracket in the desired location for Control Unit using Wall Plugs and Mounting Screws provided.

STEP 2 Fasten Control Unit including Weather Shield to Wall Mounting Bracket with locking screw provided.

STEP 3 Connect the OXI and ION plugs to the base of the Control Unit ensuring a FIRM CONNECTION.

STEP 4 Plug the Control Unit 3 pin plug into a suitable weatherproof RCD protected 10amp outlet and then plug the pump power cable into the 3 pin AC Socket located at the bottom of the Control Unit.
See ‘External Controllers’ on Page 9 for setup with automation systems.

STARTUP | BALANCE THE POOL WATER

Before you start:

• ADD REQUIRED CHEMICALS AND SALT/MINERALS BEFORE STARTING THE NAKED SYSTEM.
• Recommended TDS Levels are 800-1200ppm meaning salt levels are typically 500-700ppm only.
• If using MINERAL salts, allow 20-30% more minerals based on the pool salt chart below.
• DO NOT add Cyanuric Acid to the pool.
• DO NOT add Stabilised Chlorine to the pool.
• DO NOT add Copper based Algaecides to the pool.
• NEVER add Salt or Minerals directly to the skimmer box.

Before starting the Naked System balance the pool water using the calculators in the Naked App (download using the QR code on the back cover) or use the information below:

STARTUP | PROGRAMMING THE SYSTEM

Did you know?

The digital display on the Control Unit will typically explain each step and how to adjust or save the desired setting.

Programming the Naked System is completed in 6 simple steps using the following controls which are located in the centre of the Control Unit keypad :

Did you know?

STEP 1 Set the Clock’s Time of Day.

STEP 2 Choose if you added Salt or Minerals.

STEP 3 Choose whether there is existing copper in the pool.

For retrofitting existing pools, check copper levels prior to starting the system.
If copper is existing at adequate levels of 0.2ppm – 0.5ppm, choose YES.

Did you know?

Typically all new pool installations will not contain copper. The system will run for one hour per one thousand litres for the initial start-up only to achieve correct copper levels. Time remaining will display on the screen for the customer and the pool can be used immediately.

STEP 4 Set the Pool Size (Litres).

Did you know?

The volume of water in the pool determines the run times of the system for both initial startup (injection of copper) and automatically sets the pump run times on a daily basis.

STEP 5 Choose Outdoor or Indoor Pool.

Did you know?

When selecting indoor pools during startup the unit will automatically reduce the OXI output to 50% to avoid chlorine levels increasing. Once the startup process is complete, the OXI output will automatically default back to 100%*.

*Consider reducing OXI output ongoing for indoor pools depending on usage.

STEP 6 Choose if a Naked pH Controller is connected.

• Note that this can be turned on at any time should a NKD-pH Controller be added at a later date through the main menu.

STEP 7  Choose Variable or Single Speed Pump.

As variable speed pumps need longer run times, this screen allows you to adjust Timer 2 to extend run times ensuring adequate circulation. Note that T2 is for circulation only.

STARTUP COMPLETE

The system will run for a given period of time based on the pool size to get correct copper levels into the water. During this time the control panel is locked until the startup is completed. The system will then switch to AUTO mode with the timers automatically set for daily operation including the pump and filter . If the option of copper was selected as YES, the system will go direct to AUTO mode with the correct timers set.

TIMER 1 (T1) = SANITISATION. Oxidiser, Ioniser and Pump are running.
TIMER 2 (T2) = CIRCULATION. Cell is in OFF mode. Pump only is running. Cell is ON for the final hour of T2 only.

Did you know?

If you are retrofitting an existing pool that has high salt levels, the unit will automatically reduce the OXI output to compensate for the high conductivity ensuring correct output levels. Once the startup process is complete, the OXI output will go back to 100%.

STARTUP | EXTERNAL CONTROLLERS

The Naked System is compatible with any external pool control system and will slave to the controller allowing it to switch the unit ON and OFF. There are two options depending upon the pool’s environment and use. If unsure, please contact us for further information.

Did you know?

• The Ioniser will always switch off based on the volume of water entered so that copper levels will not increase regardless of the Timers set.
• There is a Water Flow Sensor in the OXI Cell. Please make sure the pump is running whenever the Naked System is ON during Timers 1 and 2.

OPTION 1 – Typical setup for most pools with automation

STEP 1 Press the Clock/Timer Button and then select option EXT. CONTROL.

The Control Unit will be set to ON (Manual) mode and display EX on the main DDS screen.
NOTE: The Unit cannot be put in AUTO mode when the EXT. CONTROL option is set via the Clock/Timer.

Did you know?

When using Option 1 the OXI will always be producing when unit is running so you may prefer to reduce OXI output to stop chlorine levels increasing.

OPTION 2 – For indoor or very small pools

STEP 1 Note the timer settings from the Naked System (which were automatically configured when the pool size was entered).

STEP 2 Enter Naked System timer settings into the timer settings of the external controller to switch unit ON and OFF.

Example on a 50,000L Indoor Pool:

T1 ON TIME 08:00 → T1 OFF TIME 13:00. (Sanitisation)
T2 ON TIME 13:00 → T2 OFF TIME 08:00 (Filtration only)

Did you know?

Timer 2 (T2) ON TIME must be adjusted to the same as T1 OFF TIME and T2 OFF TIME must be adjusted to the same as T1 ON TIME. Resulting in the system running in AUTO mode for 24 hours.
