#1 What do you mean by stackable? Does this mean I can put the washing machine on top of it?
Stackable simply means that you can stack this dryer on top of a compatible front load washing machine. Just ensure that you use an anti-vibration rubber mat and that the width and depth of the dryer is smaller than that of the washing machine so that it is safe and stable. You cannot put a washing machine on top of a dryer under any circumstances.
