The hood is shipped in knock-down form and must be
field assembled. The indoor coil access panel is used as the
hood top while the hood sides, divider and filter are packaged
together, attached to a metal support tray using plastic stretch
wrap, and shipped in the return air compartment behind the
indoor coil access panel. The hood assembly’s metal tray is
attached to the basepan and also attached to the damper using
two plastic tie- wraps.

pan and remove. Locate and cut the (2) plastic tie-wraps
securing the assembly to the damper. (See Fig. 12.) Be

ing any wiring.
