Replacement Cartridges & Consumables

An AOP system has one scheduled consumable. The cartridge is what actually generates the hydroxyl output, and it is designed for roughly a year of service. Replacing it on schedule is the entire maintenance programme for these units.

Matching the cartridge to your system

• CCW100 and CCW50 units share a common annual replacement cartridge.
• CCW25 spa and swim spa units take their own dedicated annual cartridge.

Check the model number on the unit itself rather than going by pool size, since a pool and spa combination may be running a system you would not guess from the water volume alone.

Why the schedule matters

Cartridge output falls off gradually rather than stopping outright, which is exactly what makes it easy to miss. Nothing alarms and nothing visibly breaks. What happens instead is that chlorine demand quietly climbs back toward where it was before you installed the system, chloramines begin returning, and swimmers start noticing the smell and the eye irritation again. By the time the symptoms are obvious you have usually spent more on extra chlorine than the cartridge would have cost.

A practical habit

Order the next cartridge when you install the current one and set a calendar reminder for eleven months out. Facilities running multiple units should keep one spare on the shelf so a replacement never waits on shipping. Commercial operators frequently align cartridge changes with a seasonal shutdown or an annual service visit so the labour is already accounted for.
