11. When the plenum is plumb and level, use the screws that
were provided to attach the plenum section to the AcuAir
unit. (The screws are shipped loose and can be found in the
blower section). The predrilled holes indicated in the plenum
frame show the location and number of attachment points
required. The plenum assembly must be securely screwed to
the unit.
12. Replace the access panel, ensuring that all screws are in
place.
13. When a set of detached hoods is shipped separately, one
hood will require a 1” hole in the side for mounting the fresh
air temperature sensor. Locate the hood nearest the sensor
and electrical flex conduit. Drill a 1” hole and insert the sensor
conduit probe and secure the j-box to hold the assembly in
position. (Figure 29)
