Unscrew the end of the faucet and take that piece with you to your local hardware store. Tell them you want a fitting that will take its place and allow you to attach a garden hose. They'll get you hooked up. Probably find it in the dish washer area.
Then, depending on what you got with your chiller, find what adapters you might need to go from the new fitting to your chiller. Like what is posted above.
