Notes:
• Use DRI-STEEM's hard pipe adapter kit to connect the steam outlet to hard pipe. Use a hose clamp to
connect the steam outlet to vapor hose. Use a hose cuff and clamps to connect the steam outlet to
tubing.
• Thin-walled tubing heats up faster than heavy-walled pipe causing less steam loss at start-up.
• Hard pipe or tubing diameter must match HUMIDI-TECH steam outlet size (DN40 or DN50).
• See the Maximum Steam Carrying Capacity and Steam Loss tables on Page 18.
• Position dispersion tubes perpendicular to horizontal airflow.
• Pitch header toward condensate drain.
• Make sure header and tubes are square in the duct, slanting only to allow the pitch of the header.
• Secure header at both ends.
• Dashed lines indicate provided by installer.
• Dispersion tube sizes:
– DN40
– DN50
• When mounting the humidifier above the level of the RAPID-SORB, see the drawing on Page 17.
• Failure to follow the recommendations on this page may result in excessive back pressures on the
humidifier. This may lead to dispersion tube(s) spitting, steam blowing through water seals, or leaking
gaskets.
