I'm looking at IKEA's Frostig BCF228/64 integrated 70/30 fridgefreezer as it has auto defrost on both compartments - and a 5 year guarantee!
The FF has a depth of 560mm and width of 540mm. The housing unit is 570mm wide and deep, so I'm OK on the width, but is 10mm suffient at the rear? I know I have to provide top and bottom venting of 200cm2.
IKEA can't answer this question and Whirlpool's (the manufacturer) customer support team can't find this model on their system....and there's nothing shown in the instruction manual.
