proper condensate disposal requirements.
UNIT INSTAllATION
ground level — When installing the unit at
ground level, provide a concrete mounting pad
separate from the building foundation. The
pad must be level to insure proper condensate
disposal and strong enough to support the unit’s
weight. Refer to figure 3. Make sure the slab is
a minimum of 2” above the grade and in an area
that drains well. See figure 6.
Rigging and Hoisting — The unit should be lifted
using slings and spreader bars. The spreader bars
are necessary to prevent damaging the top of the
unit’s cabinet. Make sure that the lifting equipment
is adequate for the load. Refer to figure 3 for unit
weights. Keep the unit in an upright position at all
times. for rooftop installations, remove and
discard the two supports attached beneath
the unit.
