More features

• 【NOTE】4‑Wire to 3‑Wire Wiring Instruction: The 4‑wire version comes with four inner cores: black, white, red and green. To adapt it for a 3‑wire electrolytic cell, manually short‑connect the inner cores of the green wire and black wire. Connect the combined black‑core wire to the black terminal of your electrolytic cell, then match white‑to‑white and red‑to‑red. This modification requires customer manual wiring and cannot be completed using the factory‑supplied crimp terminals.
• Easy Connection: Intellichlor replacement kit, product Includes closed-end union cap, o-ring, and coupling nut. With 4 button connectors, waterproof and moisture-proof, easily connect the wires at both ends. The arrow on the switch indicates the direction of the water flow to ensure correct installation.
• Product Features: The Acid Washing Kit is used to clean the salt pond to remove the calcium deposits contained therein and prolong the life of the salt system. The wires have been a strip of the flow switch. Only take several minutes to make the "no-flow" warning light go off.
• Installation Tip: PTFE thread seal tape is required for installation. Start with 3 wraps—reduce if too tight, add 1‑2 wraps if loose or leaking. The fitting should go in smoothly by hand; use a wrench only for fine adjustment (within 1/2 turn) to align the flow arrow. DO NOT over‑tighten to avoid thread damage.
• Compatibility Reminder: Designed for Pentair IntelliChlor IC‑15, IC‑20, IC‑40, IC‑60. NOT COMPATIBLE with iChlor‑Series iChlor15, iChlor25, iChlor30. Please double‑check your equipment model before ordering to avoid wrong purchase and return.
