OPERATING THE CONTROLLER

• 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.

NOTE: WHEN STARTING THE NKD-PH FOR THE FIRST TIME THE ACID PUMP WILL AUTOMATICALLY PRIME WHEN THE INITIAL STARTUP BEGINS OR WHEN T1 IS ACTIVATED.

THERE ARE 2 MENUS FOR PH CONTROL

1. pH1 RUN TIME
   • Adjusts the run time of the acid pump.
   • Run time is displayed in minutes indicating the run time of the acid pump each day when T1 starts.
   • If pH levels are high simply increase the time by pressing the [+] button.
   • If pH levels are low simply decrease the time by pressing the [-] button. Adjustments may be necessary, we recommend adjusting the Run Time by 1-2 minutes and checking pH levels until the correct levels are achieved.
2. pH2 DEMAND or PRIME
   • Used to manually dose acid or to prime the acid line after changing the acid drum.
   • Displayed in ml, the default is 100ml and can be adjusted up to 5000ml.
   • The acid pump will dose the required amount entered and once completed will return to the RUN TIME in pH1
   • Calculate the amount of acid required by using the Dosing Calculator in the Naked Pools App. Simply select the ml required by pressing the [+] and [-] buttons and [OK] to conrm.

MAINTENANCE

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.

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.

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.

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.
