I'm just curious as to how outdoor units are fitted in the UK and US with regard to health and safety. In Spain, a lot of installers just put the unit on their shoulders and walk up the ladder. I personally have a table winch where you place the unit on a bench and then wind it up, but even that is heavy and cumbersome. I also use an electric winch/pulley/ladder combination, using an extra set of ladders to pull the unit up. Are there any other options?
