EL35 Chlorinator

Description

The Zodiac EL35 is the larger model in the EL-Series salt chlorinators, designed to handle the sanitation needs of bigger residential pools with ease. It produces up to 35 g/h of chlorine, making it suitable for pools up to about 120,000 L in cooler climates (or ~75,000 L in hotter climates). The EL35 inherits the EL-Series’ robust, low-maintenance design – including a self-cleaning reverse-polarity cell that greatly reduces calcium buildup – ensuring consistent chlorine output without frequent interventionzodiac.com.auzodiac.com.au. Built tough for Australian conditions, the EL35 features simple one-touch controls and built-in timers that allow you to automate your pool’s filtration and chlorination schedule. Key highlights are its reliable performance (even in large pools), an adjustable output to fine-tune chlorine levels, and a reputation for being “plug and play” – an easy replacement for many older chlorinators. Whether you’re maintaining a busy backyard pool or a smaller commercial installation, the Zodiac EL35 provides ample sanitizing power with minimal fuss.

🔧 Key Features

• High Capacity Chlorination: Delivers up to 35 grams of chlorine per hour, keeping water hygienic in larger pools. It’s well-suited for pools up to 120 kL (in mild climate) or ~75 kL (in warm climate).
• Self-Cleaning Cell: Incorporates a reverse-polarity (auto-cleaning) electrode that periodically reverses current to shed scale. This means the cell stays cleaner longer, maintaining efficient chlorine production and reducing cell cleaning frequency.
• Built-In Timer Control: The EL35 includes an internal time clock with multiple programmable periods. You can easily set when the pump and chlorinator turn on/off each day, ensuring consistent sanitation while optimizing energy use.
• Adjustable Output: Features a chlorine output control dial (or buttons) that let you adjust the percentage of chlorine production. Increase it in summer or for heavy bather loads, and decrease during cooler periods to avoid over-chlorination, thereby extending cell life.
• Sturdy & Reliable: The EL35’s durable design includes high-quality UV-resistant plastics and a weather-sealed electronics module, giving it longevity under harsh sun and poolside conditions. It’s a set-and-forget system known for requiring little attention beyond basic water chemistry checks.
• Compatibility & Retrofit: Designed to retrofit Zodiac’s older Tri or LM series units (and others) with minimal hassle – often no plumbing changes needed. This makes upgrading to an EL35 straightforward for those replacing an aging chlorinator.

🛠️ Technical Specifications

• Chlorine Output: 35 g/hour maximum.
• Pool Size Compatibility: Up to ~120,000 L (temperate climate) or ~75,000 L (tropical climate):contentReference[oaicite:228]{index=228}.
• Optimal Salt Level: ~4,000 ppm (the system is optimized at 4,000 ppm salt at 25 °C) with an acceptable range typically 3,500–6,000 ppm:contentReference[oaicite:229]{index=229}. Low salt indicator triggers around ~3,000 ppm.
• Cell Type: Reverse polarity self-cleaning cell with solid plate design. Cell model Zodiac EL-35G (35 gram). Clear housing for visual inspection, standard 50 mm ports (40 mm adapters included).
• Electrical: 220–240 V, 50 Hz, single-phase. Comes with lead and plug. Back-up battery for timer memory (ensures timer settings aren’t lost during power outages).
• Pump Outlet: Controlled outlet for pool pump (max 8 A). Synchronizes pump operation with chlorination cycles – when the timer turns off, both pump and chlorinator shut down (or pump can run independently if set to manual override).
• Enclosure: Splash-proof rating IPX5. Should be wall-mounted in a ventilated area out of direct sprinklers or heavy rain exposure (though resistant to typical outdoor moisture).
• Warranty: 2 Years full warranty on power pack & cell (with an option for extended pro-rata on cell in some regions, per manufacturer’s policy).
