Answer
Guillermo:

I'd probably hold off on the water for a bit. There is no magic formula for what is enough. I expect the roots are pretty deep, so they can go w/o for awhile. Check soil from time to time- not letting it get too dry. These trees are slow growers, but pretty drought tolerant. Be sure to keep vegetation away from trunk and watch out for that string trimmer/lawnmower-- the killer of many trees and shrubs.
