plenum, the accessory roof mounting curb must be installed
on and flashed into the roof before unit installation. The in­
structions for installing the curb are packaged with the
curb.
CAUTION: Be sure that the roof will support the additional
weight. Refer to Figure 5 or 6 for weight information. On a
downflow installation with a-Model 542D or a Model 542E
with an accessory downflow plenum where the accessory roof
mounting curb is not being used, the field-fabricated support
must be level and must properly support the unit and down-
flow plenum.
When installing a Model 542E without an accessory down­
flow plenum, place the unit on a level base that provides
proper support. On flat roofs, be sure that the unit is at least
4 inches above the highest expected water level on the roof
to prevent flooding. Consult local codes for installation re­
quirements.
NOTE: See Figure 10 for a typical rooftop installation.
B. Ground-Level Installation
The unit must be placed on a solid level concrete pad that is
a minimum of 4 inches thick and that extends approximate­
ly 2 inches beyond the casing on all four sides of the unit.
The unit does not need to be secured to the pad except when
required by local codes.
NOTE: See Figure 11 for a typical ground level installation.
