Connecting Quick Connect Fittings

Quick connect fittings simplify installation. Follow these steps to connect and disconnect tubing:

1. To Connect: Insert the tubing a half-inch deep into the fitting. The tubing will lock into place. For added security, insert a locking clip around the collar of the inner sleeve.
2. To Disconnect: Shut off the feed water inlet and turn on the connected faucet to release pressure. Remove the locking clip (if used). Press the collar inward and pull the tubing outward simultaneously.

Operating

Once installed, the iSpring FT15 filter operates continuously as water flows through your system, providing improved taste and odor reduction. Ensure all connections are secure to prevent leaks.
