ROOF CURB & SLAB MOUNT
ROOF CURB - Install accessory roof curb in accordance with
instructions shipped with curb (See Fig. 6). Install insulation, cant
strips, roofing, and flashing. Ductwork must be attached to curb.
IMPORTANT:
The gasketing of the unit to the roof curb is
critical for a watertight seal. Install gasketing material supplied
with the roof curb. Improperly applied gasketing also can result in
air leaks and poor unit performance.
Curb should be level to within 1/4 in (See Fig. 8). This is necessary
for unit drain to function properly. Refer to accessory roof curb
installation instructions for additional information as required.
SLAB MOUNT - Place the unit on a solid, level concrete pad that
is a minimum of 4 in. thick with 2 in. above grade (See Fig. 10).
The slab should extend approximately 2 in. beyond the casing on
all 4 sides of the unit. Install a 6-in. gravel apron in front of
