If the unit is to be installed on a hot sun exposed roof or a black-topped ground area, the unit should
be raised sufficiently above the roof or ground to avoid taking the accumulated layer of hot air into the
outdoor unit. At the same time, an adequated structural support for the unit is necessary.

In case any obstacles exist above the outdoor unit, such obstacles must be 1,524mm above the
outdoor unit.
