Hayward CL220 Chlorine Feeder

Offline installation means the feeder is installed parallel to your existing plumbing rather than directly in the main return line. It uses small feeder tubes to pull water from the plumbing, sanitize it, and return it to the system, which makes it much easier to retrofit onto existing pool setups.

Yes, the CL220 is designed to work with either Trichlor tablets or sticks. It is not compatible with bromine or other chemical types, so be sure to stick to Trichlor to avoid dangerous chemical reactions.

The unit has a capacity of 9 pounds of chlorine tablets or sticks. This allows for extended periods between refills, depending on your pool's size and chlorine demand.

Yes, the dial allows you to control the flow of water through the feeder, which directly dictates how much chlorine is dissolved and dispensed. You will still need to test your pool water regularly to find the right setting for your specific pool volume and environmental conditions.

The Easy-Lok threaded cover is designed for safety and security, but it is straightforward to operate. It features a locking mechanism to prevent accidental opening, so just ensure you follow the instructions to depress the locking tab while turning to open it safely.

The CL220 is rated for a flow rate between 50 and 90 GPM (gallons per minute). If your pool pump operates significantly outside of this range, you may need to adjust your plumbing or consider a different model to ensure proper chemical distribution.
