Code. Also, the unit location must be far enough away from any
structure to prevent excess roof run-off water from pouring directly
on the unit. When choosing the location of the unit(s), sound
transmission through air and refrigerant lineset should be taken
into consideration. It is recommended to locate unit(s) away from
areas (bedrooms, etc.) where such sound could be objectionable.
4. The top discharge area must be unrestricted for at least five (5)
feet above the unit.
5. When the outdoor unit is mounted on a roof, be sure the roof will
support the unit's weight. Properly selected isolation is recom-
mended to prevent transmission to the building structure.

indoor unit should NOT exceed sixty (60) feet.
7. If outdoor unit is mounted above the air handler, maximum lift
should not exceed sixty (60) feet (suction line). If air handler is
mounted above condensing unit, maximum lift should not exceed
sixty (60) feet (liquid line).
