Foundation; Ductwork - Trane Precedent WSC060ED Installation, Operation And Maintenance Manual

Foundation

If the unit is installed at ground level, elevate it above the
snow line. Provide concrete footings at each support
location with a "full perimeter" support structure or a slab
foundation for support. Refer to
operating and point loading weights when constructing a
footing foundation.
If anchoring is required, anchor the unit to the slab using
hold down bolts or isolators. Isolators should be installed
to minimize the transmission of vibrations into the
building.
WARNING
Heavy Unit!
Ensure the roof is strong enough to support the
combined unit and support structural weight. Refer to
Table 1, p. 16 for the unit operating weights.If unsure,
contact a structural engineer. Failure to follow
recommendations could result in roof collapsing under
the unit's heavy weight which could result in death or
serious injury and property damage.
For rooftop applications, ensure the roof is strong enough
to support the combined unit and support structural
weight. If anchoring is required, anchor the unit to the roof
with hold-down bolts or isolators. Check with a roofing
contractor for proper waterproofing.

Ductwork

and return air openings as viewed form the rear of the unit.
Elbows with turning vanes or splitters are recommended
to minimize air noise due to turbulence and to reduce static
pressure.
When attaching the ductwork to the unit, provide a water-
tight flexible connector at the unit to prevent operating
sounds from transmitting through the ductwork.
All outdoor ductwork between the unit and the structure
should be weather proofed after installation is completed.
