1
5 FT. ABOVE UNIT — UNRESTRICTED
Clearance must be provided in front of control box (access panels)
& any other side requiring service access to meet National
Electrical 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
recommended to prevent transmission to the building structure.
6. The maximum length of refrigerant lines from outdoor to
indoor unit should NOT exceed sixty (60) feet.
Since the manufacturer has a policy of continuous product
and product data improvement, it reserves the right to
change design and specifications without notice.
