fore setting unit on roof curb. These struts are intended to
protect unit base frame from fork lift damage. Removal is
accomplished by extracting the sheet metal retainers and
pulling the struts through the base of the unit. Refer to rig-
ging label on the unit.
Important: If using bottom discharge with roof curb,
ductwork should be attached to the curb prior to installing
the unit. Ductwork dimensions are shown in Roof Curb In-
stallation Instructions.
Refer to the Roof Curb Installation Instructions for proper
curb installation. Curbing must be installed in compliance
with the National Roofing Contractors Association Manual.
Lower unit carefully onto roof mounting curb. While rigging
