User Manual Ivation IVA-DM45 Dehumidifiers

No, there is no way to open it completely. Try peroxide (my
favorite) or concrobium (recommended) to get rid of the mold.

It has a fan and moves air with the built in fan. Ours has
become louder but still operates very well (it is in a dusty area
of our home.

It does generate a little heat. Nothing compared to
compressor dehumidifiers. And it will resume operation
after being unplugged and plugged back in shortly after, a
minute or so, so I would assume it would continue after a
power outage.

Yes it will turn on as long as the power switch is left on..it
does default back to 50 percent humidity so if the humidity
in the area is under that it will not start pulling humidity
from the air..if the airs humidity is over 50 it will start the
process..if you wish you can toggle the down switch to
readjust..if you turn the main power switch off to empty the
water tank the same thing well be seen when the power is
turned back on.

Yes, this will help dry out the room. When the shower is off, of
course. This would work for a small to medium sized
bathroom.

No it can not be mounted. Every side had a use, but It is
compact enough to set on a wide shelf.

Yes, that's where ours is and it works very well
