Figure 6-4. Condensate drained through piping loop seal.
Make sure outlet of loop seal is below bottom of HumidiPack
header.
NOTE: When installing HumidiPack for use with an electric or steam-to-steam
humidifier, minimize the length of piping run from the humidifier to Humidi-
Pack. Piping should not extend longer than 20 feet and should be a generous
size (at least 2"). Consult factory if longer piping is necessary.
Slope piping back toward humidifier or toward a drainage point. Pipe a loop
trap to an atmospheric drain at any low points in piping run. Install, at
minimum, a 10" loop seal from the HumidiPack header drain connection.
