3. Appliance description

The appliance is a wall mounted electric direct heater for areas such as workspaces, kitchens, bathrooms and similar. The quiet fan draws in the indoor air that is heated by a bare wire heater element. The air then exits evenly through the hot air chan- nel and the air discharge grille set into the bottom of the appliance. When the set room temperature is reached, it is maintained by periodic heating. Overheating protection The appliance is equipped with a high limit safety cut-out that switches the appliance off in case it overheats. Once the cause of the fault has been eliminated, the appliance restarts within a few minutes (cooling period).

The appliance is operated using the programming unit which is located at the top right of the appliance front. D0000075720
