DRI-STEEM Installation Guide: ULTRA-SORB
®
Model LV, evaporative steam, installed in an AHU horizontal airflow 3 of 4
Draining and lifting condensate
Since the ULTRA-SORB
®
operates with virtually zero internal pressure, condensate cannot be piped directly into a
return main and, therefore, should either be wasted to a floor drain or piped into a small condensate pump for
return to the steam source. In either case, the drain connection of the ULTRA-SORB must be at an elevation that
will permit gravity drainage. To prevent steam from escaping from the drain line, install a water seal P-trap in the
drain line. See drawing below for water seal height. For lifting condensate, use DRI-STEEM condensate pump
(Part No. 400280 for 115 V or Part No. 400281 for 230V) rated for 212 °F (100 °C) and suitable for lifting 250 gph
(16 L/m) with a 20-foot head (60 kPa).
