  • Page 17: Notes On Operation

    Notes on operation After 24 hours in standby operation (no humidity demand), the steam tank is emptied automatically. The steam tank remains empty and is not filled until a steam demand is present or the bathing operation is started manually. If, during operation, it is recognized that consistently foaming occurs in the steam tank, the carbonate hardness setting of the inlet water should be increased.
