• The humidifier is mounted in position near the furnace.
• Now a hole is cut on the insulation of the forced-air duct. Thereafter a hole is drilled through the duct.
• The steam wand of the humidifier is connected to the duct at the hole with the help of screws.
• A steam hose is connected to the wand at one end and to the wall-mounted humidifier at the other end. The hose is secured with cables.
• A thin flexible drain hose is also joined to the steam wand and to humidifier.
• A drainage pipe is run from the bottom of the humidifier to a floor drain.
• Now you need to make an arrangement for suppling water to your humidifier. This is done by connecting it to nearby water supply. A cooper tee fitting is soldered into a cold water pipe. A pipe is connected to the humidifier.
• An electric cable is run from the room humidistat to the humidifier.
• An air-proving switch is installed in the duct.
Contact a good HVAC technician who will connect you humidifier to you central heating and cooling system. However always keep in mind that these units will function only when your forced-air system is on. They’re controlled by the humidistat.
