the provided section joining plates to fasten sections
together. Space them as shown in Figure 6. Using the
provided ¼"-14 × 1" self tapping screws, drill screw the
joining plates into the frame channel on each section,
keeping unit sections tight together. Follow instruction
drawing included in the assembly kit.

For positive pressure sections (sections located after the
supply fan), a base rail join piece needs to be installed to
provide a good seal in the bottom of the air handler.
For high pressure, low leakage units, ensure that the D-gasket
is attached to the entering air side frame channel
it has dislodged during shipping, restore to original location.

1. Adjust the base rail clip bolts to fit over the adjoining
base rail flanges (loose enough for the piece to slide and
yet tight enough to provide a good seal). See
2. Push the clip with a long narrow board or broom handle
(something half the width of the unit) to the center of
the air handler top panel, as close to the center of each
panel (of each half) as possible. Secure the mounting
straps (longer strap found in the splice kit) as shown in
Figure 8.
