Use the 4 provided screws and nuts to attach the 2 fan adapters to the buckets. Each fan adapter requires 2 screws and 2 nuts to secure it to the bucket.
Make sure that the top bucket is snuggly fit into the base bucket. The snug fit should prevent any air from leaking out of the sides of connecting the two buckets. There are two bucket extensions that can be used to extend the height of the system.
Note: You can mount the power strip to the side of the base bucket with duck tape. As a note of caution, please remember to plug the power strip into a GFCI socket. Doing so will prevent serious shock from the wall power supply if something were to go wrong.
