Units are shipped with the side duct openings covered and a
covering over the bottom of the unit. For bottom duct application, no duct cover changes are necessary. For side duct
application, remove the side duct covers and install over the
bottom duct openings. The panels removed from the side
duct connecti ons are designed to be reused by securing each
panel to its respective downflow opening. But keep in mind
that the supply panel is installed with the painted surface UP,
facing the heat exchanger, while the return panel is installed
with the painted surface DOWN, facing the downflow duct
opening. The supply panel is secured with the bracket
(already in place from the facto ry) and two screws. I t’s a snug
fit for the panel when sliding it between the heat exchanger
and unit bottom, but there is room. The return panel is
