Anyone entitled to remove an installation from a thing that they are to return to another person is to restore the thing, in the event of removal, to its previous condition at their own expense. If the other person obtains possession of the thing, then that other person is obliged to permit the installation to be removed; they may refuse permission until they have been provided with security for the damage connected to the removal.
