How to Use the Intelichlor 523730: Complete Guide

Step 1: Initial Setup and Installation

Before you buy Pentair IntelliChlor Plus30 cell, ensure your power center is compatible. Installation is straightforward if you are replacing an existing 523009 cell. Turn off all power to the pump and salt system at the breaker. Unscrew the old cell from the plumbing, disconnect the sensor cable, and remove it. Install the new 523730 cell by sliding it into the existing canister or directly into the plumbing, ensuring the O-rings are properly seated. Reconnect the sensor cable and power up the system. The cell will run a quick self-diagnostic check.

Step 2: First-Time User Guide

Once powered on, the LCD display will show the current salt level and cell status. You may need to calibrate the system if this is a first-time install. Use the interface buttons on the power center to set your desired chlorine output percentage. For a 30,000 gallon pool, start at 50% output and adjust based on water testing. The system will automatically adjust production based on water flow and temperature.

Step 3: Core Functions and Daily Use

Daily operation is mostly hands-off. The cell produces chlorine on demand as water flows through it. You can monitor production levels via the LCD display. Regularly check the “Status” indicator for any warnings. The IntelliChlor Plus30 pros cons are most apparent here: the diagnostic system is excellent, but you must pay attention to the alerts to avoid scaling or salt issues.

Expert Tips for Maximum Value

Tip #1: Optimize Output for Season

Adjust the chlorine output percentage based on water temperature. In summer, run at 60-80%; in winter, drop to 20-40%. This extends cell life and saves energy.

Tip #2: Maintain Proper Salt Level

Keep your salt level between 3200-3400 ppm. This is the sweet spot for optimal chlorine production without excessive corrosion of metal fixtures.

Tip #3: Use a Stabilizer

Maintain cyanuric acid (CYA) levels between 60-80 ppm. This protects chlorine from sunlight degradation, allowing the cell to work less and last longer.

Tip #4: Clean the Cell Proactively

Do not wait for the “Cell Cleaning Needed” warning. Inspect the plates every 3 months and clean if there is any visible scaling. Use a compatible cleaning stand for easier maintenance.

Tip #5: Run Pump During Peak Sun

Run your pump and salt system during the middle of the day when chlorine demand is highest due to UV exposure. This maximizes efficiency.

Tip #6: Monitor Flow Rate

Ensure your pool pump provides adequate flow (minimum 20 GPM for the cell to operate). Low flow will trigger errors and reduce chlorine output.

Tip #7: Regularly Update Firmware

If using IntelliCenter, check for firmware updates for the automation system to ensure optimal cell communication features.

Common Mistakes to Avoid

1. Mistake: Not balancing pH before installation → Solution: Always test and adjust pH to 7.4-7.6 before activating the cell. High pH causes scaling on the plates.
2. Mistake: Running the pump too short → Solution: The cell needs at least 6-8 hours of pump runtime per day to maintain proper chlorine levels for a 30K gallon pool.
3. Mistake: Ignoring diagnostic warnings → Solution: Address “Low Salt” or “Cell Cleaning” warnings immediately to prevent permanent damage to the cell plates.
4. Mistake: Adding too much salt at once → Solution: Add salt in increments and allow 24 hours to dissolve before retesting. Over-salting can cause error codes and corrosion.
5. Mistake: Using acid without proper safety gear → Solution: Always wear gloves and goggles when cleaning the cell with muriatic acid. Neutralize spills immediately with baking soda.
