For the fins I vacuumed first using the soft brush attachment as you do not want to bend the thin delicate vains. Then I tried the steam cleaner with nozzle attachment which was a fail as not enough water (steam). Then tried a 2 litre hand sprayer. Used a square bucket underneath to catch the water run off. Two washes first with soapy water then plain water to rinse off. Working from bottom to top then back down again in vertical sections with the bucket underneath. Only a layer of towels on the floor is needed without the need for plastic barriers. Worked well enough for me and as you can see these guys are professionals.
Putting back together. You should have your screws lined up in little cups or trays to help with reverse order assembly. Easier to put the drain tray back on with the air flap separated. The air flap can be added later. The little motor for the horizontal air flaps needs a bit of thought to twist back into place. Needed to clean off any dust and mold so that it sits right in the rectangular hole. The holding screw was tight so needed to test screw in and out while the tray was out to make assembly easier once on the ladder. The little motor wires need to be threaded just so otherwise you will not have enough length. I used a little petroleum jelly (vaseline) to lubricate both the plastic tray pipe bit and the rubber drain pipe. This will help to the refit.
For the roller unscrew the hidden right hand side screw first. There is a part of the right side of the roller that servers as a window to see the hidden screw (ie some of the blades are not there on purpose) Do this first before unscrewing the left hand side. Not shown in the video. 2:06 shown screwing back in the screw so it does not get lost.
I realised there's a black, foam air/vibration seal between the radiator and the plastic housing at the back. That seal had perished and stuck the radiator in place, so I just needed to wiggle it and pull it really hard. Also, because that seal had previously not been put back in correctly when someone else serviced the unit, so it was sticking out and the drum/fan was flicking on it (which was the reason I was disassembling the unit). I just ripped off the perished parts, cleaned everything and reassembled the unit. Seems OK. My top tip is to smear a bit of silicone grease in the end of the rubber drainage hose (if it's fitted at the right end). Makes it so much easier to reassamble, as the plastic tube slides back into the hose. Also, if your unit is nearly against the ceiling and you can't reach the 3 latches at the top, but some grease on those too, so that they assemble/disassemble more easily. p.s. These Panasonic units are very poorly designed. Mitsubishi better (I'm a design engineer).

Thanks a lot man, mine was so moldy. Now my family can breathe clean air.
Thank you sir! Now I know what I can clean myself and what I can leave to the professionals.

Cleaned my AC as u guide
Best
Thanks a lot bro
Mine will trip off and the timer light goes on with ac , is this an issue caused by not cleaning?
What's his house like that he can take a hose inside and unload 50 litres of water inside?
Wiring tu tak payah buka dulu ke?
Thanks a lot. Now I can save my money from AC cleaning.
Obviously the filters do little and a major Spence to have a HVAC service $700….was.
thanks for sharing. The desgin is... so stupid to clean.
01:55 My radiator won't move so I can't get the drum out :(
