Make sure your unit it tilted slightly to the outside. This way, the water will run to the drain.
IF necessary, extend the drain away from the house so the water doesn't run into, say, a crack near your foundation. The next thing you know, you'll be telling us you have some water running in a window, or somethin', and you don't know where it's coming from.
Also, if you live in an apartment or condo where there are 'people' below, have the maintenance man do something about 'moving' the drain line. (How many times have you walked down the street along some business where you've gotten dripped on.) And lastly, since the water will drip continually when the unit is on, there's a great tendency for mold and mildew to form where the water lands. It won't matter if it's the ground below OR the wall of the house! That's why the location of the drain line 'matters'.
My best to ya and hope this helps.
PS: You can mix water and bleach in a 16 to 1 ratio (respectively) and run it through the hole from time to time to keep the line and pan 'clean'. HOT water is best. Watch out for the fumes though ...
