I was looking for the installation manual as well. I have everything but this one - I'm pretty sure it got thrown out with a bundle of newspapers and flyers.
And of all manuals to lose, this is the worst one. Without it you have no hope of installing the door properly.
Fortunately another thread on this forum mentioned going to Whirlpool and entering in the model number - keep in mind, in North
America
, all IKEA appliances are made by Whirlpool. The model number is on a sticker just inside the door on the left (mine was IUD9500WX2). Don't look through Whirlpool's models, you won't find it. You have to enter it as a search term in Whirlpool's literature database:
Whirlpool Product Literature Search
...and entering that in, it popped up right away. They are the exact ones, IKEA branded and all.
I just wanted to put this as a little reference here for people who come across this thread in a panic like I did.
