Installed very easily and takes less room. Like the cord connection exiting from side so unit can be pushed into place without damaging cord. 
One concern is that drain seal gasket is in different position than prior unit. Instructions say to use supplied connection elbow which has a wide end flange. Unfortunately existing unit was connected with a straight pipe and no elbow. Straight pipe has a smaller end flange. It sealed end I hope this won't leak on the long term.
