It's important to install the LEGIOMIX valve body with the actuator on the top or side of the piping, never on the bottom. Follow the diagrams below; this information can be found in the INSTALLATION and COMMISSIONING manual. Note the hot water into the valve will be piped to the red connection port and the cold water into the valve will pipe to the blue connection port. The mixed water will exit through the tailpiece where the gauge is located. Full installation and commissioning details can be found in the installation instructions.
