TYPICAL SYSTEM INSTALLATION
NKD-pH uses a 1 : 3 Acid/Water mix ratio. Add 15L water then 5L of acid to a 20L
drum. Always add acid to water, never water to acid.
Install the Clear Injection Tee Piece before or after the OXI & ION Cell Housing
taking note of the flow direction indicator.
All installations must be after any heating.
Store the acid drum at the furthest possible point away from all equipment.

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.
