2) Space dimension for dual-module unit
3.2.2 Space requirement for the top of outdoor unit
When the unit is located in a totally open space with no obstructions in four directions, keep the
distance between the unit top and wall at least 1500mm (59inch) or above (See Fig.5). When space is
limited within 1500mm (59inch) or the unit is not set in an open space, air return pipe is required to be
installed in order to keep good ventilation (See Fig.6).
