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.

Minimum Airflow Clearance
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. Care should be taken to ensure the
unit is installed away from noise sensitive locations such as
bedrooms, windows and outdoor living areas. Ensure the
foundation is sufficient to support the unit. A concrete slab
raised above ground level provides a suitable base.
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 heat pump unit legs or frame and
the roof mounting assembly to reduce noise vibration.
The following elevation minimums are recommended:
Design Temperature Suggested Miminum Elevation
+15° and above 2 1/2"
-5° to + 14° 8"
below -5° 12"
NOTE: These units require special location
consideration in areas of heavy snow accumulation
and / or areas with prolonged continuous
subfreezing temperatures. Heat pump 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.
Electrical Noise
The unit should be well grounded so that potential
effects of electrical noise from the inverter to surrounding
equipment can be minimized.
When selecting an installation location, keep sufficient
distance from the heat pump unit and wiring to radios,
personal computers, stereos, etc., as shown in the
following figure.
