PURPOSE:To eliminate production of condensed water and to automatically stop leakage water from a connector by stopping a fan according to a variation in an electric resistance value generated due to looseness of the connector, etc. CONSTITUTION:A pair of electrodes 17, 21 for holding a drain connection port 15 of a connector and a drain pipe 19 are provided. A controller 25 for measuring an electric resistance between electrodes and generating a fan stop signal based on a variation in a measured resistance value is connected to the electrodes 17, 21. |
