Installation
Foundation
Horizontal Units
If the unit is installed at ground level, elevate it above the snow line. Provide con-
crete footings at each support location with a "full perimeter" support structure or a
slab foundation for support. Refer to Table 1 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 isola-
tors. Isolators should be installed to minimize the transmission of vibrations into
the building.
For rooftop applications, ensure the roof is strong enough to support the com-
bined unit and support structural weight. Refer to Table 1 for the unit operating
weights. If anchoring is required, anchor the unit to the roof with hold-down bolts
or isolators.
Check with a roofing contractor for proper waterproofing procedures.
