MOUNTING
Duct Mounting
Before beginning Duct Mounting:
I have confirmed local codes for proper draining practices for hot water
I have chosen an installation location that meets the requirements on page 10
Follow these steps to mount steam humidifier directly to the supply duct of the homeowner’s HVAC equipment.
STEP ONE:
Select a Mounting Location
Choose a location that has access to a cold
water supply pipe.
Select a vertical or horizontal surface on the HVAC
supply duct, with adequate clearances, where steam
humidifier can be mounted.
Make sure there is a 120 VAC electrical outlet
rated for the steam humidifier being installed.
Ensure the location is near a drain with a high-
temperature water rating. Consult local plumbing
codes for proper drainage. If no main floor drain
is available,
see “Other Plumbing Options” on page
16.
STEP TWO:
Connect the Duct Nozzle
Slide the foam gasket over the nozzle.
Make sure the o-ring gasket is properly seated
in the groove.
Insert the duct nozzle into steam humidifier. Twist
clockwise to ensure a tight seal.
