Guidelines for Adjustments
- Free Chlorine: To raise chlorine levels, add chlorine directly or adjust your equipment’s output.
- pH: Increase pH by adding buffer or soda ash; reduce pH with muriatic acid for proper balance.
- Total Alkalinity: Use sodium bicarbonate to raise alkalinity or muriatic/dry acid to lower it.
- Calcium Hardness: Adjust by adding calcium chloride, or reduce by partially draining and refilling the pool if levels are too high.
- Cyanuric Acid: Increase with cyanuric acid and decrease by partially draining and refilling.
- Salt Level: Check monthly. Add salt as needed, or drain and refill if levels are high.
Regular monitoring and adjustment following this table will keep your pool within optimal parameters, enhancing the effectiveness of your Zodiac salt chlorinator for a clean, comfortable swimming environment.
Maintenance Guide
For regions with high calcium hardness, periodic cleaning of the electrode is recommended to ensure optimal performance. Use a Salt Chlorinator Cell Cleaner or a 1:10 solution of hydrochloric acid to water, and always follow local disposal guidelines for the cleaning solution to protect the environment.

Important Notes for Zodiac TRi Series RP Cells:
1. Cells Sold Without Housings:
These replacement cells are provided without housings. You can install them directly into the existing unit, utilizing the pre-installed housing of your Zodiac TRi system.
2. Resetting Operating Hours on TRi Models:
When replacing the electrode, it is essential to reset the chlorinator's operating hours. This system tracks the total runtime of the electrode and provides alerts when it has reached 6000 hours or more.
- Cell Fault Message:
The message "CELL FAULT CHECK CELL HOURS" will appear, which does not affect the system's functionality. It is a reminder to check the cell and possibly replace it. The chlorinator will continue working while this message is displayed, but it is recommended to reset the operating hours upon installation of the new cell.
Steps to Reset Operating Hours:
- Step 1: Press and hold the SELECT button for about 15 seconds until the second menu appears.
- Step 2: Navigate to OPERATING HOURS. Note that if it has reached 6000 hours or more, it is time for a reset.
- Step 3: Press SELECT to reset the hours to zero.
- Step 4: Press MENU twice to return to the main menu.
After completing this process, the "CHECK CELL" message will disappear, and the system will continue to function normally.
