Installation
22 RT-SVX22J-EN
Figure 19, p. 22 to Figure 21, p. 22 illustrate the supply and
return air openings in a downflow configuration.
Elbows with turning vanes or splitters are recommended
to minimize air noise due to turbulence and to reduce static
pressure.
When attaching the ductwork to the unit, provide a water
tight flexible connector at the unit to prevent operating
sounds from transmitting through the ductwork.
All outdoor ductwork between the unit and the structure
should be weather proofed after installation is completed.
