The unit's weight value is on the cardboard box.
When mounting the outdoor unit on a roof, be sure the roof
will support the unit's weight. Properly selected isolation is
recommended to prevent sound or vibration transmission to
the building structure.
Figure 2-1
2.2 Location Restrictions
Ensure the top discharge area is unrestricted for at least 60
inches above the unit.
Do not locate outdoor unit near bedrooms since normal
operational sounds may be objectionable.
Position unit to allow adequate space for unobstructed
airflow, wiring, refrigerant lines, and serviceability.
Maintain a distance of 24 inches between units.
24 inches clearance must be provided in front of the control
box (access panels) and any other side requiring service.
Position unit where water, snow or ice from roof or
overhang cannot fall directly on unit.
Position the outdoor unit a minimum of 12" from any wall or
surrounding shrubbery to ensure adequate airflow.

Cold climate considerations (heat pump only)
NOTE
Precautions must be taken for units being
installed in areas where snow accumulation and
prolonged below-freezing temperatures occur.
Units should be elevated 3-12 inches above the pad
or rooftop, depending on local weather. This
additional height will allow drainage of snow and ice
melted during defrost cycle prior to its refreezing.
Ensure that drain holes in unit base pan are not
obstructed, preventing drainage of defrost water
(Fig. 2-4).
If possible, avoid locations that are likely to
accumulate snow drifts. If not possible, a snow drift
barrier should be installed around the unit to prevent
a build-up of snow on the sides of the unit.
