Outdoor units are approved for operation above 55°F in
cooling mode. Operation below 55°F requires the use of an
approved low ambient kit.
Damage to the unit caused by operating the unit in a
structure that is not complete (either as part of new
construction or renovation) is not covered under the
warranty.
Installation Clearances
This unit is designed for outdoor installations only. Special
consideration must be given to location of the condensing
unit(s) in regard to structures, obstructions, other units,
and any/all other factors that may interfere with air
circulation. Where possible, the top of the unit should be
completely unobstructed; however, if vertical conditions
require placement beneath an obstruction there should
be a minimum of 60 inches between the top of the unit
and the obstruction(s). The specified dimensions meet
requirements for air circulation only. Consult all appropriate
regulatory codes prior to determining final clearances.
Another important consideration in selecting a location for
the unit(s) is the angle to obstructions. Either side adjacent
the valves can be placed toward the structure provided the
side away from the structure maintains minimum service
clearance. Corner installations are strongly discouraged.
60"
This unit can be located at ground floor level or on flat
roofs. At ground floor level, the unit must be on a solid,
level foundation that will not shift or settle. To reduce the
possibility of sound transmission, the foundation slab
should not be in contact with or be an integral part of
the building foundation. The foundation slab should be a
minimum of 6" wider than the unit in all directions. Ensure
the foundation is sufficient to support the unit. A concrete
slab raised above ground level provides a suitable base.

For optimum performance, the minimum length
interconnecting tubing is preferred. When possible
minimize the amount of bends and turns.
Rooftop Installations
If it is necessary to install this unit on a roof structure,
ensure the roof structure can support the weight and that
proper consideration is given to the weather-tight integrity
of the roof. Since the unit can vibrate during operation,
sound vibration transmission should be considered when
installing the unit. Vibration absorbing pads or springs can
be installed between the condensing unit legs or frame and
the roof mounting assembly to reduce noise vibration.
NOTE: These units require special location consideration
in areas of heavy snow accumulation and/or areas with
prolonged continuous subfreezing temperatures. These
unit bases have cutouts under the outdoor coil that permit
drainage of frost accumulation. Situate the unit to permit
free unobstructed drainage of the defrost water and ice. A
minimum 3" clearance under the outdoor coil is required
in the milder climates. In more severe weather locations,
it is recommended that the unit be elevated to allow
unobstructed drainage and air flow. In areas of heavy snow
the unit needs to be elevated above the average yearly
snow accumulation.
Rigging
To avoid possible injury or death, all panels must be in
position and secured before lifting this equipment.
12"
Use field-supplied spreader bars when lifting the unit to
minimize the possibility of lifting cable/straps damage. To
protect the cabinet louvers, use protective material such as
plywood behind the cable/straps. Arrange the straps to form
a central suspension point. NOTE: When raising and setting
the unit, observe all safety rules. Remove shipping skid and
all protection and lifting material after the unit is in place.
