Removal was pretty straightforward. This pertains strictly to my Rpod 2017 177 HRE AC removal.
-set AC breaker to off and AC unplugged from the Rpod
-removed inside AC cover (4 screws) and gently pry off from aluminum bracket.
-disconnected AC wiring, thermostat control wiring, and 12v wiring. -there was a metal outlet box screwed into the plywood which contained the AC wiring. I removed the box.
-I took my Rpod to a local dealer and had them remove the 180lb AC unit off the roof (($50) -just prior to the local dealer picking up the AC unit off the roof, I went inside and undid 4 or 5 hex bolts holding the rooftop unit to the aluminum bracket on the inside (to which the internal cover attached). -at this point, I had an open hole in the roof and I could see where the AC, 12v, and thermostat wiring went into horizontal holes drilled in the roof plywood on the bathroom side. -I cut off the AC wires so no bare copper was showing and then put heat shrink tubing on each wire. -I bent the AC wire 180 degrees and pushed it back into the hole so it would be accessible in the future. -once the fan was centered in the roof hole, I marked each screw hole in the flange with a fine tip marker. -I then removed the fan from the hole and drilled pilot holes into the roof with a drill bit marked with tape for the correct length of the screws. -I cleaned the roof with alcohol and then applied a bead of Dicor self-leveling caulk right on top of the drilled holes all the way around the opening. -I placed the fan into the hole and then "found" the drilled holes with each screw and tightened them down by hand. -I covered each screw with more Dicor and evened up the Dicor that squished out from the fan flange with a wet finger.
-I had two 12v cables coming out of the hole and testing showed which one was live. The other one went to several lights. I used wire nuts to connect both of these existing 12v cables to the fan 12v wires. I pushed the excess 12v wires back into their hole in the plywood once the fan was installed. -I had two thermostat wires coming out of their hole in the plywood. One thermostat cable went to the wall thermostat and the other went to the furnace. -I soldered the red to red and white to white and covered both connections with heat shrink tubing. -I pushed the excess thermostat wires back into their hole such that they could be retrieved later. -I tucked the 12v wiring up alongside the fan housing and the plywood. -I removed the AC thermostat from the wall and installed a new thermostat.

-I tested the fan, thermostat, and heater operation.
-I held the inside fan cover up on the fan to gauge how much I'd need to cut off and then added 1/4" to that measurement so I'd have a snug fit. -I had some of the adhesive decorative paper on the roof luan board misplaced by the inside AC aluminum clamp moving around somehow. I used a hair dryer to gently heat it up and stretch it back into place. Most of these were covered by the fan cover but I wanted them smooth and flat too.
-I marked, drilled pilot holes for, and screwed the inside fan cover into the ceiling. The screws went into the aluminum frame so drilling pilot holes was a must.
-I have placed a label over the AC thermostat breaker that says DISCONNECTED.
That's it. Not too big of a chore at all.
Any questions, fire away. Sorry, no pics.
