require placement beneath an obstruction there should
be a minimum of 60 inches between the top of the unit
and the obstruction(s). The specied dimensions meet
requirements for air circulation only. Consult all appropriate
regulatory codes prior to determining nal 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.

This unit can be located at ground oor level or on at
roofs. At ground oor 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 sucient to support the unit. A concrete slab
raised above ground level provides a suitable base.
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"
The unit should be well grounded so that potential
eects of electrical noise from the inverter to surrounding
equipment can be minimized.
When selecting an installation location, keep sucient
distance from the heat pump unit and wiring to radios,
personal computers, stereos, etc., as shown in the
following gure.
