* Based on total maximum pressure drop in hose, tubing, or pipe of 5" wc (1244 Pa)

** Maximum recommended length for vapor hose is 10' (3 m). Longer distances can cause kinking or low spots.

*** To minimize loss of capacity and efﬁciency, insulate tubing and pipe.

†

Developed length equals measured length plus 50% of measured length to account for pipe ﬁttings.

When using vapor hose, use DRI-STEEM vapor hose for best results. Field-supplied hose may have shorter life and may cause foaming in the evaporating

chamber resulting in condensate discharge at the dispersion assembly. Do not use vapor hose for outdoor applications.

Connecting humidifier to dispersion assembly with tubing or

pipe (continued)

• Insulating hard pipe reduces the loss in output caused by

condensation.

• When using hard pipe, take care to remove ALL traces of

lubricants used to thread the pipe. This minimizes the possibility

of tank foaming. Denatured alcohol or mineral spirits work best

for removing lubricant.

• If the humidifier must be located above the dispersion assembly,

use the recommend installation as shown on Page 38.

• See the maximum steam carrying capacity table below.
