Note:
The Ultra-sorb must be installed with the drain
connection at an elevation that permits gravity drainage.
For lifting condensate, use a condensate pump rated for
your application. Pumps are rated by fluid temperature,
head (pressure), and flow (gpm). Contact your local
DRI-STEEM representative for pump selection.
