Vertical SDU/Winterizer Assembly

To assemble dissimilar unit sizes for an indoor vertical
SDU/winterizer configuration:
1. Apply gasketing to the mating surface of the secondary
unit (see Figure 67).

on the black unit support brackets (see
The secondary unit must be centered on the primary
unit between the black unit support brackets.
4. Install trim angles as shown in
10-16 x 3/4-inch self-drilling screws using a powered
impact gun and taking care not to strip the screws.

External Raceway Assembly

For air handling units with factory-installed power wiring
extending from the first level to the second level, wiring
must be connected and assembled in a raceway. See
Figure 70.
1. Cut zip ties. Remove protective foam cover from
connectors.
2. Attach stacked raceway harness connectors, matching
connector colors on the high voltage side and
connector numbers on the low voltage side.
3. Verify conduit size.
4. Attach covers.
5. Secure conduit. Space tie-downs no greater than 10
inches. Locate cut-screw behind conduit.
