PROBLEM TO BE SOLVED: To provide an apparatus equipped with a sensor for detecting distance, capable of improving measurement accuracy in a case that full water of drain water is detected by the distance detection sensor, and enabling easy inspection of a mounting position in a short period of time in a case that a water receiving condition is known and work need to be finished in a sort period of time, a case that only correctness of the mounting position of a water level sensor need to judged or the like when the apparatus is assembled in a showcase factory, or the like. SOLUTION: The apparatus provided with the sensor for detecting distance by sending and receiving signal wave of acoustic signal, includes the distance detection sensor characterized by identifying the sensor mounting position based on time to receiving sending and receiving signal which is radiated for a fixed period of time.
