Set the FROG @ease SmartChlor Cartridge to the setting that matches your hot tub model number.
The dial is on the bottom of the silver SmartChlor cartridge, twist it up or down.
Once set, the SmartChlor Cartridge will maintain a low 0.5 to1.0 ppm chlorine level as long as the pH stays within 7.2 and 7.8.
When to adjust:
Because SmartChlor self-regulates at a low 0.5 to 1.0 ppm turning up the dial will only result in building up the reserve faster. Therefore, it is rare that you would need to increase the setting.
If you feel the SmartChlor cartridge is dispensing too quickly:
Try lowering the setting number by one
Decrease your hot tub’s circulation time
Free chlorine will always remain at 0.5 to 1.0 ppm, by decreasing the dial you are slowing the buildup of the reserve
