Thanks to GT4 I felt brave enough to have a go at PU removal, Dinitrolling and a/c condenser replacement over the bank holiday weekend.
The only change I made was to mount the mesh inside the black ducting, rather than immediately behind the PU. It took a bit of work with a cardboard cut out first, but I was able to arrive at a shape which wedged in just around the plastic side of the rubber /plastic join of the ducting. I was then able to make it very secure with just 3 cable ties through holes drilled in the plastic.
The only slight drawback is needing to cut 2 holes the size of a 2 p piece through the mesh to allow you to get a screw driver through, with screw taped to the end, to reattach the ducting. I don't think many leaves will get through them though. The upside is you can't see the mesh when the job is finished, unless you get on your hands and knees with a torch. Next time the PU needs removal, the screws can be accessed through the holes, or the 3 cable ties can be cut and the mesh pushed out of the way to make the screws easily accessible.
I know I should have taken photos as I went along, apologies for forgetting :eh!:
