I have a model Model 700M Aprilaire humidifier, what direction should the fan be blowing? through the water evap. panel or through the vents of the humidifier.
Thank you for contacting us regarding your model 700. The fan on the 700 is designed to pull air from the duct through the water panel. After the air is pulled though the water panel and evaporates the water, the air is re-directed off of the outer cover back into the duct to be carried throughout your home.
The vents on the humidifier are designed to allow air to circulate under the cover to help cool the motor for the fan.
If you have any further questions regarding this or any of our products, please feel free to contact our customer service department at your earliest convenience.
