What to Expect From Your Humidifier The installer should review these points with the homeowner and answer any questions they have before leaving the job site. GETTING STARTED • Achieving Humidity Setpoint. It may take up to a week of continuous operation to achieve the humidity setpoint, especially if the home is dry when the humidifier is installed. This also depends on such factors as weather, size of home, furnishings in the home, and insulation. • Ideal Humidity. Home building industry experts cite 35% relative humidity as ideal for comfort and safeguarding the home during the typical dry...

GETTING STARTED Failure to comply with these requirements will result in voided warranty, improper installation, and service callbacks. Personal Safety • Wear safety glasses while installing the humidifier. • Do not cut into any air conditioning or electrical line. • Follow professional safety standards and all local regulations for plumbing, electrical, and mechanical considerations. Mounting Location • Mount the humidifier in a level position to avoid water damage and ensure maximum output. • Location must have access to a water line, drain, and power. • Do not install the humidifier where...

Choosing a Mounting Method Whether you purchased a Bypass or Fan humidifier will determine how your humidifier will be installed: Which humidifier do you have? Fan: Fan humidifiers use an internal fan to move duct air through the humidifier pad and back into the duct for distribution throughout your home. The fan model is commonly installed directly onto the supply (hot) air duct of your HVAC system. Bypass: Bypass humidifiers use the pressure difference between the supply and return to move duct air through the humidifier. Access to both the supply and return are required. The bypass humidifier...

STEP ONE: Select the Mounting Location Choose a location that has access to a water supply pipe. Cold or hot water can be used. Select a vertical or horizontal surface on the HVAC duct work, with adequate space clearances, where the humidifier can be mounted. MOUNTING Location must also have access to 120 VAC power. For the HE300 Fan humidifier, the power cord is 6 feet long. Ensure the location is near a drain. Consult local plumbing codes for proper drainage. If no main floor drain is available, see “Appendix C: Advanced Draining.” STEP TWO: Install Mounting Template to the Duct Position the...

If you are installing HE300 Fan model, proceed to page 10. Bypass Model Installation STEP THREE: Configure Humidifier Bypass Configure the humidifier bypass outlet to the side that best fits the application. If the bypass needs to be on the other side, remove the top and bottom covers. Unplug the damper wire and plug in on the other side (HE150/HE250 only). Pull the bypass clamps apart from center to remove the bypass; snap it back into place with the outlet on the desired side. Ensure that the pad is accessible. The handle of the pad holder and side panel of the humidifier can be switched so...

Bypass Model Installation STEP FOUR: Mounting Secure the support hooks on Bypass models to the bottom lip of the hole. Push the top of the humidifier back against the duct. Verify the humidifier is level and fasten the humidifier to the duct using two self-drilling sheet metal screws provided.

Bypass Model Installation STEP FIVE: Bypass Duct Installation On the duct opposite the humidifier Bypass install, cut a 6-in. diameter duct hole. • If the humidifier is on the supply duct, the 6-in. diameter hole should be on the return. • If the humidifier is on the return duct, the 6-in. diameter hole should be on the supply. Secure a 6-in. round duct starter collar into the 6-in. duct hole. Use rigid or aluminized flexible 6-in. duct to connect the starter collar to the humidifier bypass port. 2 Secure the duct to the humidifier port with self-drilling sheet metal screws using the pre-drilled...
