Horizontal SDU/Winterizer Assembly
To assemble dissimilar unit sizes for an indoor horizontal
SDU/winterizer configuration:
1. Locate the mounting hardware and gasket material.
Note: Black unit support brackets ship pre-installed on
the primary (larger) unit section.
2. Apply gasket in direction of airflow between the black
unit support brackets to the roof of the primary unit.
See Figure 64. The gasket needs to be placed such that
it will be directly under the integral base frame of the
secondary (smaller) unit to be stacked on top. The
secondary unit will be centered along the width on the
primary unit.
3. If there is an opening in the roof of the primary unit,
apply gasket perpendicular to airflow on the roof next
to the opening (air entering side only).
4. Lift the secondary unit, following instructions in
“General Lifting Considerations,” p. 25 (see Figure 18),
and place on the black unit support brackets (see
Figure 65). The secondary unit must be centered on the
primary unit between the black unit support brackets.
5. Install screws as shown in Figure 66 inserting the
appropriate screws using a powered impact gun and
taking care not to strip the screws.
6. Remove the secondary unit lifting lugs one at a time
and reinstall screws after sections are set in final
position.
