Indoor System Thermal Expansion Device
Check the indoor coil thermal expansion device to see
whether it matches the required thermal expansion device for
the indoor coil and heat pump combination being installed.
Refer to the refrigerant charge label located on the inside of
the heat pump access panel for the correct thermal
expansion device size required.
Replace the thermal expansion device with the correct size if
this size is not already installed in the indoor coil. Instructions
for replacing the thermal expansion device are provided with
the indoor coil.

Location Requirements

This heat pump is designed to be located outdoors with
sufficient clearance for free entrance to the inlet and
discharge air openings. The location must also allow for
adequate service access. See "Installation Clearances."
Where possible, select a location for the heat pump which is
shaded from the direct rays of the sun most of the time. North
or east locations are usually most desirable. Position the heat
pump to avoid direct contact with water, snow or ice from a
roofline overhead.
The heat pump must be installed on a solid, level mounting
pad that will not settle or shift. Isolate the pad from the
building structure to avoid possible transmission of sound or
vibration from the heat pump into the conditioned space.
The heat pump foundation should be raised to a minimum of
3" (7.6 cm) above finish grade. In areas which have prolonged
periods of temperatures below freezing, and/or snowfall, the
heat pump should be elevated above the average snow line.
If heat pump is to be installed on a flat roof, it should be on a
platform or other support which will raise the inlet air opening
12" (30.5 cm) minimum above the surface of the flat roof.
Avoid ice accumulation by ensuring free drainage of
condensate from defrost cycles. The heat pump should be
located away from walkways to avoid possible icing from
defrost condensate.
Avoid placing the heat pump near areas such as sleeping
quarters or study rooms. Normal operating sound levels may
be objectionable if the heat pump is placed near certain
rooms. A shift in sound type does occur during the defrost
mode. The defrost mode generally lasts no longer than
10 minutes.
Where possible, the top of the condensing unit should be
completely unobstructed.
If vertical conditions require placement beneath an
obstruction, there should be a minimum of 5 ft (1.5 m)
between the top of the condensing unit and the obstruction.
NOTE: The specified dimensions meet requirements for air
circulation only. Consult all appropriate regulatory codes prior
to determining final clearances.
Avoid corner installations if possible.
Either side adjacent to the valves can be placed toward the
structure provided the side away from the structure maintains
minimum service clearance.

Rooftop Installation
Check that the roof structure can support the weight of the
condensing unit.
Keep the weather-tight integrity of the roof during and after
installation.
Vibration-absorbing pads or springs can be installed between
the condensing unit legs or frame and the roof mounting
assembly to reduce noise vibration.

Electrical Requirements
