Same make and model is a piece of cake.
Take digital photos of all the wire connections.
One or two buddies to help get it on to the roof and old one off.
Some plywood or old carpeting to set old and new unit on so you do not cut the roof material.
Turn off all AC power (breaker if isolated to one breaker) and unhook battery.
Detach wires coming in from thermostat and AC power.
Pull 4 bolts and lift out of opening.
Clean area and replace roof seal, carefully drop new unit in hole, re attach 4 hold down bolts.
Re attach all the power and thermostat wires as per above photo.
Flip breaker on and power up unit.
