Have the unit now has 14 days in operation and am very satisfied. In order to save electric power (320 watts), I have the humidity adjusted at the regulator to around 60% and this can be done perfectly with the regulator. A hygrometer for monitoring is recommended. In locked basement room the pleasant hum is barely audible in the bedroom it would interfere. When the tank is full, the dehumidifier switches off and a red light indicates this.
