Install ductwork in accordance with NFPA 90B and any local
codes.
The use of flexible, noncombustible connectors between the
main trunk ducts and the supply and return air plenums is
recommended to minimize vibration transmission.
Plenums must be individually sealed to heat pump or
condensing unit casing with ducts terminating inside the
structure.
Flashing used to cover ductwork must permit removal of
access panels and top. See "Minimum Clearances" in the
"Locations Requirements" section.
Filters
Filters are not supplied with these heat pumps or condensing
units; however, filters must be used. It is the installer's
responsibility to install a filter rack with the ductwork and to
install properly sized filters in accordance with the Minimum
Required Surface Area for Disposable Filters chart.
