supply
You must reinforce the cut-out with a wooden frame, using
bars which are at least 20 mm wide. You may have to remove
insulation material first however.
The reinforcement frame is to make sure that the roof is not
crushed by the installation bolts and that air conditioned air
does not enter the ceiling space.
