CAUTION: Minimum duct size for mounting the humidifier is 8" x 1M-TT. Determine the most convenient side of duct for installation and maintenance. Lay out and cut a 7%" x 14-” hole on the bottom of the duct from the mounting side. On the mounting side of the duct, lay out a 7%TT wide by 7" high hole. See Figure 1. Install ,TZn bars on the 14-" sides. Slide the humidifier tray into the "Z" bars until the front flange is 3" from the duct side. Position the inspection plate on the humidifier tray
