CONNECTING TO HUMIDIFIER WITH TUBING
• See Figures 28-1 and 29-1 for interconnecting tubing pitch requirements
for single dispersion tube applications. See Table 31-1 for interconnecting
tubing pitch requirements for Rapid-sorb applications.
• Support tubing between the humidifier steam outlet and the dispersion
system with pipe hangers. Failure to properly support the entire tubing
weight may cause damage to the humidifier tank and void the warranty.
• 90° elbows are not recommended; use two 45° elbows, 1' (0.3 m) apart.
• Insulate tubing to reduces the loss in output caused by condensation.

WARNING
Excessive moisture hazard
DriSteem strongly recommends
installing a duct airflow proving switch
and a duct high limit humidistat. These
devices prevent a humidifier from
making steam when there is low airflow
in the duct or when the RH level in the
duct is too high. Failure to install these
devices can result in excessive moisture
in the duct, which can cause bacteria
and mold growth or dripping through
the duct.
