Notes:
* When piping over an obstruction, see the drip tee installation illustration on Page 39.
• Assemble multiple dispersion tubes or use a Rapid-sorb or Ultra-sorb dispersion assembly where necessary to accommodate maximum humidifier load.
• The smallest GTS humidifier steam outlet is 2" (DN50). Install an adaptor manifold if using multiple 1½" (DN40) dispersion tubes. See also Table 37-1.
