IC40 Salt Cell Replacement for Pentair IntelliChlor 🔧 Installation Instructions ✅ Before Installation: 1. Turn off the pool pump and disconnect power to the salt chlorine generator system. 2. Allow water pressure in the plumbing system to fully release. 3. Confirm the replacement salt cell matches IC40 model only. 4. Inspect O-rings and union connections to ensure they are clean and undamaged. ✅ Installation Steps: Step 1-- Power Off System：Shut off all electrical power to the pool pump and IntelliChlor control unit before installation. Step 2-- Remove Old Salt Cell：Loosen the union fittings on both ends of the existing salt cell and carefully remove it from the plumbing line. Step 3-- Check & Lubricate O-Rings：Inspect the O-rings on the unions. Apply a small amount of silicone-based lubricant (non-petroleum) if needed to ensure a proper seal.

Step 5-- Secure Connections：Hand-tighten the union fittings evenly on both ends. Do not overtighten.

Step 7-- System Check：Verify that the system recognizes the new salt cell and operates normally by observing system indicators. ✅ After Installation Tips: ① Allow the system to run and confirm normal operation. ② Follow manufacturer recommendations for system settings and routine pool maintenance. ③ Periodically inspect the salt cell for scale buildup and clean according to standard pool care practices.
