Some vertical units may be equipped with a plenum blower. In this case,
there may be several ports for supply air. Choose the port (or ports) that
allows the best duct routing. Close the other ports with the included covers.
The plenum of some vertical units may be removable. This may
facilitate moving the unit through tight clearances.
To remove the plenum, open the access panel and disconnect the motor or
the variable-frequency drive (if so equipped). Remove and retain the
mounting screws. Carefully remove the plenum, setting it aside in a
protected area.
When the unit is in its final position, re-assemble the plenum, fastening it in
place with the mounting screws. Re-connect and torque the wires to the
blower or drive.
It may be possible to re-locate the plenum of some vertical units for more
choices of supply-air direction. In this case, remove the plenum as
described above. Remove the side panel and use it to close the top of the
unit. Mount the plenum where the side panel was. (See the illustrations
below.) Re-route the blower wires and re-connect them.
