Choose a location in a
conditioned space
Place outside the grow room if possible. The capacity of the
humidifier is reduced by the length of the steam hose or pipe due
to condensation. The maximum recommended length of steam
hose is 6 feet. Use hard pipe insulated with 1" thick insulation
rated for 212°F or higher for lengths greater than 6 feet. If 6-foot
steam hose does not reach from humidifier to dispersion tube,
splice in 1" copper pipe using 3/4" x 1" reducing coupling.
See Installation Manual for more details.

Install dispersion tube
• The steam tubelets must face up
regardless of the airflow direction
in the duct. The plate is labeled
"UP" to indicate proper orientation.
• On horizontal duct runs, install the
dispersion tube low in the duct.
On vertical duct runs, center the
tube on the duct.

Duct location and
absorption distance
Absorption distance is the unobstructed straight line distance
needed for steam to be fully absorbed.
• Determine absorption distance based on the lowest air
velocity that the system will see (refer to table below).
• Locate dispersion tube in a straight section of duct, far
enough upstream of any obstructions or bends in the duct.
