Install in a location where no antenna of a television or radio exists within 3 meters.
Install in a location where at least two sides are unobstructed, so that the flow of air at the intake port or
exhaust port is not blocked, and so that sufficient space is ensured for maintenance to be carried out
without trouble. In general the top also must be unobstructed. (Figs. 5a and 5b)
