How to install a heater by crawling out a window!

My heater unit doesn’t work.  It is rather cold.  So the land lord sent over a new one.  The compressor is outside my high rise kitchen window on a small ledge.  Why in the world is it on a ledge out a window and not a balcony with a door?  It is China, that is why!  So I took pictures of the workmen removing it and installing the new one.  This is a accident in the making and an insurance law suit in America.  Enjoy the pictures.  I laughed at the entire event.  The two workers did tie a harness to each other.  Ha!  If one fell the other would topple right out my window with him!
