2. GENERAL OVERVIEW
Congratulations on the purchase of your NKD1 Fresh Water System. Please take a moment to read through
the entire manual before installing your new unit. Your system must be installed and operated as
specied.
While every effort has been made to ensure that the information contained in this guide is accurate and complete,
no liability can be accepted for any errors or omissions. Naked Pools Pty Ltd reserves the right to change the
specications of the hardware and software described herein at any time without prior notice.
Your NKD1 Fresh Water System is a true environmentally friendly system requiring far less maintenance than
traditional sanitisers. This hybrid swimming pool and spa sanitisation system uses a combination of copper and
silver ionisation as well as oxidation to treat and provide fresh water. This delivers up to 70% less salt/mineral levels
than its rivals, resulting in record low levels of chlorine being produced.
Please remember that your NKD1 Fresh Water System is not designed to chemically maintain your pool water and
keep it balanced. We encourage regular water and copper testing, balancing and correction if & when required to
maintain the recommended balanced levels of your pool water. This is a vital part of a complete maintenance
program and will ensure a trouble-free fresh water pool.
There is one design in our Naked Pools Fresh Water System range:
NKD1 is designed to optimally sanitise swimming pools up to and including 100,000L of water. Smart self-cleaning
technology allows the polarity of the OXI Cell plates to change direction every 4-16hrs (depending on your
setting). Reversing times can be changed, see 7.3 CELL CLEANING. The change of polarity causes the calcium to
dislodge and keep the OXI plates clean. Please note occasional cleaning of the plates may be necessary.
The ION Rods change direction every 3 minutes to ensure even wear and tear.
Please note the Rods are sacricial and will have to be changed from time to time (typically every 2 years)
depending on the size of your swimming pool.
Visit www.naked-pools.com or call 1800 NAKED1 (625 331) for further information.
2.1 Recommendations and Helpful Hints
• Read and keep your manual in a safe place.
• Operate the unit on manual when large number of swimmers are present to ensure sufficient water
turnover.
• Maintain your copper level between 0.2-0.4ppm at all times.
• Check your copper levels weekly with the test kit provided.
Please note pH must be adjusted to correct levels to ensure an accurate reading see 8.3 pH.
Visit www.naked-pools.com or call 1800 NAKED1 (625 331) for further information.
Do not use Stabilizer (Cyanuric Acid)
Do not use Bromine compounds
Do not use Aluminium based or any other occulants
Do not use Soda Ash (Sodium Carbonate)
Do not use Granular Chlorine
Do not use forms of Zeolite ltration media
• Maintain your TDS (Total Dissolved Solids) level between 800-1000ppm for optimum performance and
complete Fresh Water experience.
• Decrease running times when temperature goes down - see 6.7 WINTER MODE.
Thank you again for choosing a NKD1 Fresh Water System.
We wish you many happy years of swimming in your Fresh Water Pool.

3. POOL PREPARATION
Before operating your NKD1 Fresh Water System please read the following:
Handy Tips
• Check your TDS levels in your pool before starting your system.
• TDS levels should ideally be 800-1000ppm and no more than 1200ppm.
• For all new pool installations please seek advice from your pool builder before adding salt or
minerals as some new surfaces request no addition when initially completed.
• NEVER ADD SALT/MINERALS DIRECTLY TO THE SKIMMER BOX. This high concentration of
either salt or minerals will pass through your ltration, pump and other pool equipment and may
cause damage.
• The system can operate on mineral/magnesium chloride salts and you should allow an extra 20-30%
for these type of salts.
• Salt or minerals should always be added to the shallow end of the pool and allowed to dissolve. Do
not let the salt settle on the oor of the pool as this may cause damage to the surface. Use your
pool brush to mix the salt into the water.
• Running the pump will mix the water and help the salt/minerals to dissolve.
When taking your pool water to a pool shop for testing please ensure you take the
enclosed laminated NKD1 System Card to ensure your water is tested correctly and
accurate results are achieved. See handy tips 8.0 WATER CHEMISTRY.
• The only pool chemicals needed are those for normal water balance.
• Copper levels of 0.2-0.4ppm need to be achieved in order to optimally sanitise the pool water. On
initial start up the system allows for the literage of your pool to be entered and this is critical to
ensure the run times of the system and all the levels are set correctly.
If unsure visit www.naked-pools.com or call 1800 NAKED1 (625 331) for further information.

4. NKD1 SYSTEM INSTALLATION
4.2 Control Unit Installation
• The NKD1 Control Unit has an Ingress Protection Rating of IP23 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 at panel at least the
same size to act as a waterproof backing plate.
• Mount the Control Unit with the Wall Mounting Bracket, Green Plugs and Screws provided.
The Control Unit should be mounted no further than 1.5 metres from the Housing for ease of
operation.

4. NKD1 SYSTEM INSTALLATION
4.4 ION Installation
• Check that the O-ring is clean, greased with silicone grease (DO NOT use petroleum based jelly) and
securely located in the Housing.
• Fit the ION Rods and ensure the Locking Ring is rmly tightened by hand (DO NOT use a tool to
tighten).
• Connect the plug to the base of the Control Unit ensuring a rm snap lock connection.
• Plug the Control Unit 3 pin plug into a suitable weatherproof RCD protected 10amp outlet and
then plug the pump into the 3 pin AC Socket located at the bottom of the Control Unit.
NOTE: The pump rating must not exceed 8amps.
WARNING:
• We DO NOT recommend the use of valves on the inlet or outlet of the 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 installers responsibility to ensure some form of ow 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.
• It is RECOMMENDED that the Housing be installed horizontally to create a natural gas trap that
acts as a safety device. Installation in any other way may cause explosion, injury or death if the
installer does not allow for gas removal. A venturi pipe is installed/moulded within the Housing
design to eliminate any possible gas build up, although it is always recommended to ensure
proper installation to eliminate this from happening.
• The Housing must be installed in the RETURN pipework to the pool. It must always be installed
after the lter, gas heater, solar heating or heat pump.
• DO NOT apply priming uid to the Housing, it is not needed and may react with the plastic.
4.3 OXI/Housing Installation
• Connect the Housing horizontally in the return line to the pool (use reducing bushes supplied if
40mm PVC pipe) using high pressure PVC glue. The Housing can be mounted vertically but
provision must be made for a gas trap.
• Direction of water ow through the Housing is not critical although we do recommend entry from
the OXI Cell end and exit from the ION Rod end of the Housing.
• Check that the O-ring is clean, greased with silicone grease (DO NOT use petroleum based jelly)
and securely located in the Housing.
• Fit the OXI Cell and ensure the Locking Ring is rmly tightened by hand (DO NOT use a tool to
tighten).
• Connect the plug to the base of the Control Unit ensuring a rm snap lock connection.

7.4 OXI Boost
7.3 Cell Cleaning – OXI Cell Reversing Time
Smart self-cleaning technology allows the polarity of the OXI Cell plates to change
direction every 4-16hrs (depending on your setting). The change of polarity causes the
calcium to dislodge and keep the OXI plates clean. Please note occasional cleaning
of the plates may be necessary.
The factory setting is every 10 hours and this can be adjusted from as low as 4 hours
(for high calcium areas) and as high as 16 hours.
In areas where the calcium hardness of the water is low (less than 200ppm) cleaning of the cell may not be
necessary. Where calcium levels exceed 200ppm, regular inspection of the cell is necessary. Cleaning in an
acid solution may be necessary.
CELL CLEANING is entered by pressing the [OK] button in the MAIN MENU and scrolling to CELL CLEANING (Menu 3).
Pressing [+] or [-] allows you to adjust the CELL CLEANING time in one hour increments and is displayed as shown to
the right.
Pressing [<] returns you to the previous screen.

7.9 Pump Setting
PUMP SETTING is designed to protect your pump if there is no ow of water. This
means the time the pump is allowed to run after the water sensor on the OXI Cell
detects there is no ow of water. The pump will be turned off from 3 to 10 minutes,
after detecting no water ow.
PUMP SETTING is entered by pressing the [OK] button in the MAIN MENU and scrolling to
PUMP SETTING (Menu 9).
The default setting is 3 minutes and pressing [+] or [-] allows you to adjust the time the pump is turned off for.
Pressing [OK] saves the required protection time.
You can also select OFF and it will be disabled and will not stop the pump outlet.
Pressing [<] returns you to the previous screen.
For installations where a ow switch or external pump controls are used then this can be left in the OFF position.
7.5 OXI Setting
BEFORE ENTERING OXI YOU MUST BE IN THE DDS SCREEN.
This feature is particularly handy when you want to run the pump for extended
running hours (i.e. with a variable speed pump or you want additional ltration). If this
is the case OXI levels can be decreased if necessary.
The factory setting is set to 100% and in majority of pools remains at 100%. If unsure
visit www.naked-pools.com or call 1800 NAKED1 (625 331) for further information.
Pressing [+] or [-] anytime whilst in the DDS screen increases or decreases in 1% increments.
OXI Setting can also be entered by pressing the [OK] button in MAIN MENU and scrolling to OXI Setting.

7. NKD1 FRESH WATER SYSTEM MENU GUIDE
TDS TEST is designed to measure the TDS (Total Dissolved Solids) in the water. TDS is the combination of all solids
that are present in the water such as salts/minerals, calcium, sodium bicarbonate and acid.
TDS TEST is entered by pressing the [OK] button in the MAIN MENU and scrolling to TDS TEST (Menu 10).
BEFORE PERFORMING THIS TEST, ENSURE THE OXI CELL IS CLEAR OF ALL CALCIUM DEPOSITS AS THIS WILL
INSULATE THE ELECTRODES AND IMPACT YOUR READINGS. See 9.11 Inspecting and Cleaning the OXI Cell if
manual cleaning is required.
The TDS level is tested and displayed as shown to the right.
A total of 4 readings are displayed for 30 seconds in the FWD direction and then
another 30 sceonds in the REV direction.
Pressing the [<] and [>] button while in the above display and holding them in for
3 seconds brings you to this maintenance function which allows you to view the actual
TDS VALUE.
Testing starts off with FWD and if you want to check REV then press [<] and [>] in at
the same time and hold them in for 3 seconds, the direction will change to REV.
At the same time you will also be displayed the current reading in XXX.Xamps.
Pressing [<] returns you to the previous screen.
The TDS TEST measurement is meant to be a guide only as many factors can impact the result. We recommend you
take your pool water sample and Water Testing Card to your local pool shop before adding salt/minerals or replacing
your OXI Cell.
