Are all the leaves dried out? My suggestion is to move it to a location that will give it partial shade. Water it real good! Then keep an eye on it. With no leaves it will not require water as much as it would in leaf. Do not let it dry out. If it was just for one day, you may be able to bring it back. Do not over react. Only water when needed. It may take a bit of time for it to recover. Be patient. This was advise given to me about an elm of mine... hopefully you will have as good luck as I did. Patience is key....that and getting a new watering person! I do not think it matters about the dried up leaves. I left mine alone.
