INSTALLATION STEPS
OPERATING THE CONTROLLER
Attach Wall Mounting Bracket in the desired location for the NKD-pH using the
Wall Plugs and Mounting Screws provided.
Snap the pH Controller into the locating pins of the Mounting Bracket.
Install the Clear Injection Tee Piece before or after the OXI & ION Cell Housing
taking note of the flow direction indicator. Note: This should be installed after
any heating.
Measure and cut the Clear Flexible PVC Tube for the Clear Injection Tee Piece.
Use the remaining Clear Flexible PVC Tube for the acid drum, keeping the acid
drum a minimum of 2m from any equipment.
Drill a 6mm hole in the lid of the acid drum for the Clear PVC Flexible Tube and
attach Acid Drum Label to the cap.
Connect the Clear PVC Flexible Tube to the base of the peristaltic pump (left
side) and feed through the 6mm hole into the acid drum and attach to the Acid
Drum with weighted Suction Valve.
Connect the Clear Flexible PVC Tube to the base of the peristaltic pump (right
side) and attach to the Clear Injection Tee Piece.
Plug the pH Controller cable into the programming plug on the base of the
Naked Control Unit.
Plug the piggy back plug into the AC socket on the base of the Naked Control
Unit and then the pump into the piggy back plug.

It is important to understand a certain amount of owner maintenance and care is
required to keep your investment operating properly. We recommend the following
basic maintenance and further information can be found on the Naked Pools App.
4.1 Injection Point on Injector Valve
Check the injection point periodically by inspecting the Clear Injection Tee Piece for
build-up of solid matter at the end of the PVC tubing. While unscrewing the BLACK
lock nut, take care not to lose the rubber O-ring.
4.2 Lubricate Squeeze Tube
Lubricate the pump squeeze tube every 3-6 months. Use a silicone-based lubricant
only as petroleum-based lubricants will cause damage to the tube and rollers.
4.3 Replace Squeeze Tube
Depending on usage, the squeeze tube may need replacement after 1-2 years of use.
Before replacing, ensure that the suction and injection tubes are empty. To replace
the squeeze tube, please follow the instructions included with the replacement kit,
or on the Naked Pools App.
Only use original sized commercial grade Tygon® Norprene® tube as incorrect sizing
will result in early failure of the Tri Roller Block.
The NKD-pH is based on an algorithm and is designed to dose acid into the pool
each day based on a preset time in accordance with the pool size entered during the
Initial Start-up.
The pH controller will be activated each day when T1 starts and will run for the
preset time based on the pool size.
If pH levels are high, longer running times will be required, and similarly if levels are
low, run times will need to be decreased. Every swimming pool is different
depending on the set up and environment.
To change dosing times simply press [OK] for the Main Menu within the Naked
Control Unit and using the [+] and [-] buttons select M15 pH Control.
