What happens to the freezer if the condensor is blocked from air circulatio?

My new integrated fridge freezer (AEG SANTO) housing (supplied by the kitchen fitting company) completely blocks the air flow from underneath and above in contradiction to the manufacturer's manual which recommends ventilation space of 200 cm2 below and above. The freezer still works but what is likely to happen in future if the weather gets hot over the summer? Surely the machine cannot perform to its A Rated specification in the long term.
