Installation
18 RT-SVX46C-EN
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.
For rooftop applications, ensure the roof is strong enough
to support the combined unit and support structural
weight. Refer to
Table 1, p. 17 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.
