Foundation
Horizontal Units
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
Table 1, p. 17
for the unit’s
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.
