The fan is in place!

After two days of work the main unit is in place. (One instruction video suggested it would take an hour!)  The inner section and electrics still need to be installed and connected.
While I was working up there, partly standing on the bed with my upper body through the hole, I did a really good clean-up of the roof around the hatch. It was easier to do like that and opportunities to clean the roof easily don't come along so often.
At the end of the day I was so tired I went to bed early and couldn't even raise the energy to blip!
One last push to get the job finished tomorrow!
