Hookup a Regular Washer and Dryer instead of Stackable Combo

We moved into a condo where there're hookups for a stackable washer where the dryer is on top. I see that there are the following hookups:

-- hot and cold water in a hole in the wall
-- black horizontal opening with a rim in the same hole, on its bottom edge
-- dryer electric plug above that hole in the wall
-- metal tray with a rim on the floor with a small drain hole

Is the hole in the wall for both dumping the water and the top-unit dryer exhaust? If I have a regular washer and a separate dryer, can I hookup both to that hole somehow, or make the washer drain through the hole in the floor?

 

Do you own the condo? If not the landlord is going to handle the problems. In addition to what you posted you don't mention a 120v receptacle for the washer. Is this a real hole or a box set into the wall? Some pictures would help. http://www.doityourself.com/forum/el...your-post.html

 

We don't own the combo, but the owner is willing to install the combo. It just so happens that the movers delivered our original washer and dryer and I'd rather connect them than have store them again... I'll make a pic when at home. There's plenty of 120V outlets around and close, but the current hookups are in a box inset in the wall in the closet dedicated to this thing, with the metal tray with a drain hole on the bottom of the closet...

 

There should be a hole in the bottom of that box. That is where the washer drain goes. That is probably the emergency pan not a drain for the washer.
