Soft start technology allows the compressor to ramp up its speed gradually, eliminating the massive "surge" of electricity common in old-fashioned AC units. This is a standard feature on the Bravo Milano 9,000 BTU, making it much friendlier for homes with older electrical panels. In a Quad-Zone system, soft starting prevents the lights from flickering when the system kicks in. You can further protect your electronics by exploring the surge protectors in our Other Accessories section. If you are using a Single-Zone unit on a generator during a power outage, this feature is absolutely essential. A sturdy Ground Stand ensures the unit is stable during these initial rotation cycles. Soft starting reduces mechanical stress and significantly extends the life of the compressor motor.
