A − Slab Mounting
When you install the unit at grade level, the top of the slab
should be high enough above the grade so that water from
higher ground will not collect around the unit. See figure 3.
Slab should have a slope tolerance away from the building
of 2 degrees or 2 inches per 5 feet (51 mm per 1.5 m). Refer
to the next section (roof mounting) for barrier construction if
the unit must face prevailing winter winds.
