No, my question is without changing anything. He told you here how everywhere there are people who do the work without considering anything. Clearly in the installation manual ask to remove the outside equipment from a wall 20 to 30 cm. And you go and find it screwed up on the cement roof. No team resists it. Some worse unscrewed simply leaning up. The first strong wind leaves it without coolant. But of course the bad weather was to blame. Then one goes over the budget to do things properly and they tell you but nooo it is three times more than what ..
