horizontal-airflow duct, consider the following:
– DN40 dispersion tubes: Use a fastener of sufficient length to
accommodate the 1% pitch requirements toward the DN20
header drain fitting.
– DN50 dispersion tubes: The bracket can be mounted flush to
the ductwork. The 1% pitch typically can be accomplished in
the length of the hose cuffs used to connect the tubes to the
header.
