Just bought a new fridge freezer and on unpacking it, one of the tubes on the back is quite bent (see bottom left of both photos - not sure how quickly they'll upload though). I know nothing about fridges and was too cheap to pay for installation which I feel mostly vindicated in because most of the installation has been super easy - but just not sure if this tube is important, and the instruction manual doesn't say and Google isn't helping. Anyone know please? And if it being bent is an issue?
