PROBLEM TO BE SOLVED: To prevent trouble due to an error in installation works, in a low-temperature storage chamber used for containing/storing rice, vegetables and the like. SOLUTION: This low-temperature storage chamber 20 is provided with a controller 40 comprising a power source circuit section 50 for converting AC input into DC input and a power source voltage determining means 51 for determining the voltage output from the power source circuit section 50, and a warning display lamp 55. Thus, even when a different voltage is input mistakingly at the time of installation, the chamber notifies an installation worker of the error in installation works by turning off the control of a cooling unit 22 and turning on (lighting up) the warning display lamp 55 and thereby, errors in installation works and breakage of the controller can be prevented.
