<p>PURPOSE: To prevent power supply failure due to storage failure by forcibly lifting an elevation unit even when the operation of a rising operation switch is interrupted in a storage state visual observation difficult section after the unit starts to be lifted. CONSTITUTION: When the operation of a lifting operation switch PB1 is interrupted in a section in which the visual observation of the storage state of an elevation unit in an air conditioner body is difficult, i.e., an incomplete storage preventing section after the unit is once started to be lifted, a self-holding contact closes a self-holding circuit by a forcible operation relay R provided in a forcible operating circuit 43 to forcibly operate to lift the unit. Accordingly, the unit is stopped when it is forcibly operated to the normal storage position, and the power supply contactor of an air conditioner body is electrically connected to the contactor of a functional component mounted at the unit. Thus, the power supply failure due to the storage failure can be effectively prevented.</p> |
