Static discharge prevention refers to the grounding and shielding of the indoor unit’s circuit board to prevent damage from environmental electricity. Every Bravo Milano 12,000 BTU Universal Floor/Ceiling unit is built with an anti-static casing to protect its delicate logic chips. This is especially important for our Multi-Zone systems where a single surge could affect multiple rooms. Our Installation Kits include heavy-duty grounding wire to ensure a safe electrical path for the entire system. For extra protection in storm-prone areas, you can find surge-protecting Accessories in our online store. This protection ensures that the UFC Multi-Zone series remains reliable even in the most demanding climates. Investing in proper electrical safeguards during installation is the best way to prevent unexpected repair costs.
