My unit seems to be dumping alot of water into the drain 3gals every 2 hrs. Is the metering valve adjustable at the locknut screw on the end of metering valve?
Thank you for your email regarding your model 700 Aprilaire humidifier. The feed rate of your model 700 is 6 gallons per hour(GPH). The evaporation rate is .75 GPH. If the humidifier were to run a solid hour it would evaporate .75 GPH and the remaining 5.25 GPH is used to flush away the minerals left behind from the evaporation process. Based on the operation we described above and your email it appears your model 700 is operating properly.
