No expert here. I would start it 2 feet off the water. Then I would Lower it an inch a day till your around 10 inches.

Start 16-18" off of the water line. Shorten your photo period by at least an hour while acclimating. Generally the LEDs are run for dawn/dusk, so this is with the assumption that you are doing the same.

If your current photoperiod is 10 am to 8 pm, then I would do the following:

LEDs on at 10:30 am, T5s on at 11:30am, T5s off at 6:30pm, LEDS off at 7:30pm

Increase your photoperiod until its where you want it. After the photoperiod is where you want it, thenlower the light fixture until you are happy with the coral response. I run my ATI Sunpower 8x80w + ReefBrite at ~11" off the water and hit 660 PAR 4" down and 270 on the sandbed. With running a 48" fixture on a 48" tank, you wont have any really low light areas within the tank, so you'll need to be careful if you have lower light loving corals, as they wont have a low PAR area if you bring the fixture down too far.

Good Luck!
