Installation Mechanical
There should be no obstruction above the heat pump
module to interfere with fan discharge of heated air. Even a
partial overhang of an eave or awning can trap hot air and
significantly degrade heat pump performance.
Each heat pump module must be as far away from any wall
or barrier as space allows. Sufficient clearance must be
maintained between the heat pump modules and any walls
or other objects that can interfere with the free flow of air to
the air coils.
Screening fences must have 50% open surface area, with
one foot of bottom clearance, and must not extend higher
than the top of the fan grill. Modules should be a minimum
of three feet away from any fence. Failure to follow these
minimum requirements may result in performance
degradation.
Modules located in a sub-level or pit require special
considerations to avoid air recirculation.
Do not attach ductwork to any fan or fan shroud. Contact
product support for guidance on any potential ducting
applications.
Refrigerant piping should be sufficiently flexible to prevent
transmission of noise and vibration into the building.
Figure 1. Recommended heat pump clearances
Note: These clearances are general recommendations.
Each installation has specific considerations.
Contact Trane for definitive guidance and approval
on a job-by-job basis.

If the desired location for the heat pump is confined by
walls, fences, overhanging roof eaves, or is located in a pit
(sub-level site), contact Trane to discuss potential impact
on equipment performance.
The National Electric Code or local, state, and regional
building codes may require greater clearance for the
modular heat pump than the figures listed in this
publication. Always consult local regulatory agencies to
ensure additional clearances are not required by building
codes.
Service Access
Clearance must be maintained between the module and
any nearby wall or impediment to provide sufficient room to
access power distribution panel and electrical and control
panels for routine maintenance and servicing. 36 to 48
inches of clearance is required to meet local and national
electrical codes. Compressors, filter-strainers, and liquid
line shutoff valves are accessible from any service access
panel.
