I would cut back slightly on the watering, only doing so when the top inch or so of soil is dry, otherwise the soil will become waterlogged. Move to a shady area, it will survive but may lose all its leaves early this year.

If the pot is not too large, place the whole pot in a tub of water and allow the compost to get soaked (the water should come about 3/4 of the way up the pot). Leave it overnight then lift the pot out and allow it to drain. Hopefully it will be OK next year.

I forgot to water my potted acer and nearly all the leaves went crispy so I moved it into shade, removed the nearly dead leaves and made sure it didn't dry out, it's now recovered and back in its old spot, with new leaves appearing.
