Product Overview
The Hayward CL220ABG Automatic Above-Ground Pool Chlorinator is an off-line chemical feeder designed to provide steady, controlled chlorination for above-ground pools and spas. With a large 9 lb tablet capacity, this chlorinator helps reduce frequent refilling while automatically feeding sanitizer into the pool water as the pump and filter system operate.
Designed for new or existing above-ground pool installations, the CL220ABG uses slow-dissolving chlorine tablets, sticks, or bromine tablets to help maintain clean, clear, properly sanitized water. Its off-line design installs outside the main return plumbing, making it a practical option for systems where an in-line feeder is not preferred or where plumbing space is limited.
Ideal For
This Hayward CL220ABG off-line chlorinator is ideal for above-ground pool owners who want a reliable, automatic tablet feeder that helps maintain sanitizer levels with less manual dosing.
Best suited for:
- Above-ground residential pools
- New or existing pool equipment systems
- Pools using slow-dissolving chlorine tablets or sticks
- Pools where an off-line feeder is preferred
- Equipment pads with limited plumbing space
- Pool owners looking to reduce daily manual chlorine additions
- Applications requiring up to 9 lb chemical capacity
Key Features
Off-Line Above-Ground Chlorinator
The CL220ABG is designed specifically as an off-line automatic chemical feeder for above-ground pool applications. It works with the pool’s pump and filter system to feed sanitizer automatically while the system is running.
Large 9 lb Tablet Capacity
With a 9 lb chemical capacity, this chlorinator can hold multiple slow-dissolving tablets or sticks, helping extend the time between refills and making routine pool care more convenient.
Adjustable Dial Control Valve
The built-in dial control valve allows users to adjust the feed rate, making it easier to fine-tune chlorine output based on pool size, water temperature, bather load, and seasonal demand.
Uses Tablets or Sticks
This feeder is designed for large or small slow-dissolving Trichlor chlorine tablets or sticks and may also be used with compatible bromine tablets when appropriate for the pool system.
Durable ABS Construction
The chlorinator body is made from durable, corrosion-resistant ABS material to withstand demanding pool equipment environments and chemical exposure.
High-Quality Viton Seal
A Viton seal helps provide dependable chemical resistance and a secure lid seal during operation.
Easy-Lok™ Threaded Cover
The Easy-Lok threaded cover is designed for safe, convenient access when adding tablets or sticks, helping make refills faster and easier.
Finger-Release Safety Catch
A finger-release catch provides added security at the cover, helping prevent accidental opening and supporting safer chlorinator handling.
Installs Without Cutting Main Plumbing
Because it is an off-line feeder, the CL220ABG connects using tubing and fittings rather than requiring the unit to be plumbed directly into the main return line.
