The vertical plenum module includes a filter and a
space for a hot water coil. If the unit is installed in an
area where water may cause damage, be sure to set the
unit inside a drain pan.
The return air opening for the vertical plenum module
is in the front. If connecting to a flexible duct, you will
need the return air adapter. The return air adapter
attaches to the front of the return plenum module using
latches, which need to be moved from the top to the
sides (figure 8).
