LOCATION SELECTION
Install the unit in an indoor area that allows easy
removal of the filter and access panels, and has
enough room for service personnel to perform
maintenance or repair. Provide sufficient room to
make fluid, electrical, and duct connection(s). If
the unit is located in a confined space such as a
closet, provisions must be made for the return air
to freely enter the face of the unit’s air coil. On
horizontal units, allow adequate room below the
unit for a condensate drain trap and do not locate
the unit above supply piping.
Service clearance for SM units up to 6 tons
includes the following recommendations.
• 18" minimum, 24" optimum in front of the
blower access panel for access to the blower
and blower motor if needed.
• 24" minimum, 36" optimum in front of the front
access panel for access to electrical
components, compressor, and service valves if
needed.
BLOWER CONFIGURATIONS
Horizontal (HZ) Blower Configuration
The HZ configuration water source heat pump is
designed to have a field-configurable blower
orientation: end blow to straight through. An
accessory kit is required to make this conversion.

NOTICE: These units are not approved for
outdoor installation; therefore, they must
be installed inside a structure in a
conditioned space. Do not locate in areas
that are subject to freezing.
NOTICE: Discharge air configuration change
is not possible on Heat Pumps equipped
with field-installed Electric Heat (end blow).
