Mount the Beam power unit using detailed instructions included with it. Strip the ends of the low voltage wire coming into the garage and connect them to the power unit. Plug the power unit into an electrical outlet, flip the manual override switch on/off to test it. Then plug in the lightweight hose to clean up any minor mess you may have made installing the inlets. Congratulations! You're on your way to a cleaner, healthier — old or new — home.
