NOTE: If the installation

includes an energy

the unit first, placing it

in this same orientation

on the end of the

curb without the duct

connections.

If setting on the roof curb or a duct furnace curb section, verify that sealant tape is

applied to all top surfaces.

IMPORTANT: Verify that the lift operator knows the correct placement of the unit

so that the airflow orientation will be correct. When placing a unit on a horizontal

flow curb, be sure the unit is being positioned as illustrated in

FIGURE 13.

test lift the unit before attempting to install it on the roof. To prevent injury, death, or

equipment damage when lifting, use ALL lifting points.

Test lift the unit to be sure that it is secure and the weight is balanced. Lift the unit slowly, following safe lifting proce-

dures.
