Electrical Installation
This humidifier is intended to be wired independently of the
integrated control panel on your furnace. This will provide
power to the humidifier at all times, causing the evaporator pad
drum to rotate constantly.
Read the instructions in the furnace installation manual
carefully before attempting installation or operation of this
humidifier. Failure to follow these instructions may result in an
improper installation and therefore, void the manufacturer’s
warranty.
WARNING
Improper electrical wiring can cause personal
shock, injury, or property damage. It is
required by local codes that the unit be
installed by a properly qualified HVAC
technician or electrician, following NEC and
any other local codes.
