Safe to open window sash with installed AC (with brackets)? SlickRik 07-27-2006

I have an LG LW1804ER window air conditioner that was professionally
installed in an apartment building window. It does have support
brackets outside that angle from the bottom-back of the unit and rest
against the brick facade of the building. I'm on the fifth floor, by
the way.

I need to open the window sash to do a couple of things. I'm going to
put a "Stop-Drop" foam covering on top of the external AC enclosure to
dampen the sound of the upstairs neighbor's AC unit, which is directly
above mine. It drips water constantly, which is like the proverbial
water torture inside our apartment. As an aside, this is what I'm
going to install:

http://stop-drop.com/

Anyway, I also want to clean the windows, which are vinyl types that
swing into the inside of the apartment for cleaning.

My question is this: There are just a couple of small screws fastening
the top inside bracket of the AC unit to the sash. I can't imagine
that the window itself is supporting too much weight of the AC (in
other words, the natural force of the AC to want to just fall out of
the window) because of the brackets underneath the unit. But, I'm not
sure.

I don't want to remove the screws and open the sash only to have this
thing lurch toward the outside and somehow fall. Yeah, yeah, with the
brackets, that shouldn't be possible. But the only dumb questions are
those that aren't asked. Should this be safe for me to do? It will
only be me working on this thing for the time the window(s) will need
to be opened. I'm no weakling, but I only have two hands, and can't do
the work I would need to do with only one hand, lol.

So, am I good to go on this project? Tks.

Are the AC brackets bolted to the building? If not, then I wouldn't think
that you'd want to do anything with the unit unless there's someway to
support it from the inside.

They're not bolted to the building, but wouldn't any outward/downward
pressure on the unit (by removing support from the window sash) just
increase the pressure on the support brackets against the building? In
other words, essentially making the support bracket holding power even
greater?

Can you pull the unit out of the casing?

Funny you mentioned that, because I just stopped at a hardware store
for the "Stop Drop" foam covering I mentioned above, and that was one
of the suggestions. I wouldn't want to pull it all the way out as it's
pretty heavy. It would be a bear for me to get it back in without
damaging some radiator fins and whatnot. But maybe slide it out far
enough so it still has some window support (sill) and still allow me to
do my work.
