The installation space is the minimum total space recommended to allow air to circulate around the fridge for optimum energy use and performance. If there's no gap at the rear of overhead cabinets, then the recommended space above may increase by about 40mm. Many fridges are designed to sit proud of the cabinetry, so you'll often find that the required depth is less than the depth of the fridge. We display claimed measurements, and err on the side of caution when it comes to recommended installation requirements, allowing at least 5cm space on each side and 10cm for the top and rear for installation. This allows good airflow around the fridge for heat dissipation. Check manufacturers' installation instructions for precise measurements, as they can vary.
