Should my Aprilaire Humidifier be hooked up to hot or cold water?

Friday, June 8, 2012 by Aprilaire Team

Consumer question:

I have a Aprilaire 600m model and should I conect the water supply to the hot or cold line.

Aprilaires' response:

Thank you for your email regarding your model 600M Aprilaire humidifier. Your Aprilaire humidifier will operate on hot, cold hard or soft water. We do however recommend hot water as it will increase the evaporative capacity of the humidifier. Hot water will also allow you to operate your humidifier during a fan call. A heat source is required for the evaporation process. During a fan call the only source of heat is hot water.

Thursday, December 13, 2012 by Pat:: I have my fan on the furnace set to on not automatic. So I have it running all the time to circulate the air better. By doing this will the aprilaire constantly be running or only when the heat actually kicks in? Or do I have to wire it differently?
