Description
New Water 407C Replacement Chlorine Cycler Pac for In-Ground Pools
Drop-In Chlorine Convenience for In-Ground Pool Cyclers
The New Water 407C Replacement Chlorine Cycler Pac is a prefilled chlorine cartridge designed for compatible in-ground pool cycler systems. It helps simplify routine pool sanitizing by reducing the need to measure loose chlorine tablets or handle chlorine directly.
This replacement pac works with the cycler’s control dial to release chlorine gradually into the pool water. Its controlled erosion design helps limit how much chlorine is exposed to water at one time, supporting a more consistent sanitizer output for cleaner, clearer pool water.

Product Details
Compatibility and Requirements
The New Water 407C Cycler Pac is intended for compatible New Water in-ground cycler systems, including New Water Models 400 and 430. It is also associated with select Pool FROG XL Pro compatibility, so confirm fit with your specific cycler model before purchase.
Use only the factory-recommended replacement pac for your system. Do not use loose bulk chlorine tablets, refill the cartridge, or substitute non-approved chemical cartridges inside the cycler.
How to Use
Before installing a new chlorine pac, make sure pool water is balanced and the circulation system is operating properly. Turn off the pump, set the cycler dial to 0 or minimum, and open the cycler according to the manufacturer’s instructions.
Remove the required cut-off sections from the pac, then insert it into the cycler with the open end facing down and aligned with the key inside the unit. Do not force the pac into place. Replace the cap, restart circulation, and set the control dial based on your pool size, pump run time, and chlorine test results.
During the first week, test free chlorine regularly and adjust the dial gradually until the chlorine level stabilizes in the recommended range. Check the pac periodically and replace it when empty. Do not open, refill, or reuse the pac.
