A: Once all components are installed, MAXIMUS may be tested and placed into service immediately. As part of installation, the filter floor leveling coarse and flume end plug (as necessary) must cure for 24 hours minimum before MAXIMUS may be installed. The HILTI chemical anchors for the perimeter frame and nozzle plates require 12-hour minimum bond time. Afterward, the remaining components of MAXIMUS may be installed, and the underdrain promptly tested and placed into service.
