Pitch requirements
• For Rapid-sorb with the header outside a
horizontal-airflow duct, consider the following:
– 1½" (DN40) dispersion tubes: Use a fastener of sufficient
length to accommodate the 1/8"/ft (1%) pitch requirements
toward the ¾" pipe thread (DN20) header drain fitting.
– 2" (DN50) dispersion tubes: The bracket can be mounted
flush to the ductwork. The 1/8"/ft (1%) pitch typically can be
accomplished in the length of the hose cuffs used to connect
the tubes to the header.
• See Table 33-1 and the drawings on the following pages for
pitch requirements.
