The Samsung WindFree 1-Way Cassette must be installed by a qualified professional in accordance with national electrical and safety regulations. The unit is designed for ceiling mounting, requiring a compact space due to its 135mm height. Ensure the unit is firmly fixed and that the drain hose is positioned to allow for correct, safe water runoff. Refrigerant piping and electrical connections must be performed according to the specific system manual. If the unit is installed within 500m of the seashore, specialized anti-corrosion treatment is mandatory. After physical installation, the WindFree panel must be attached securely to the cassette, ensuring no gaps remain between the panel and the ceiling to prevent air leakage. Finally, verify that the controller software is updated to the latest version to enable full WindFree functionality.
Fixed units must be installed by a qualified F-gas engineer. Find an installer — we'll match you with a local HVAC professional.
