The Daikin FCAG71B Round Flow Cassette must be installed by a qualified professional in accordance with local regulations and F-gas requirements. Mounting involves securing the unit into a suspended ceiling, ensuring sufficient clearance for airflow and maintenance access. Refrigerant piping and electrical wiring must be connected according to the specific technical manual provided with the unit, ensuring all joints are leak-tested and vacuum-purged. The system uses R32 refrigerant, requiring careful handling and adherence to safety protocols regarding flammability and pressure. Once installed, the decorative panel and air filter should be attached. First power-on requires checking the system via the wired or wireless controller to ensure correct operation of the 360-degree airflow and sensing features. Always consult the official installation manual for specific torque settings and wiring diagrams.
