What setting must my fridge and freezer be at. Thanks

RFA70 settings Controlling the Temperature of the Fridge Compartment The left hand control wheel on the front panel adjusts the internal fridge compartment temperature. The internal temperature should be 5?C or colder, although some sections such as the salad bin will be slightly warmer. The setting of the control wheel will depend on the location of the fridge freezer, the room temperature and how often the door is opened. The normal set point (marked by a 3 on the dial) is usually suitable. If you need to adjust the temperature turn the control wheel using a coin to avoid damage: Clockwise (higher number) - Colder Anti-clockwise (lower number) - Warmer
