Humidifier Configuration

most conditions without the need to change its
configuration.

optimal performance, Resideo strongly
discourages changes to the configuration of the
humidifier not described in these instructions.
Before Installation

corresponds with humidifier voltage and phase as
indicated on humidifier’s specification label.
2. Ensure that the dedicated external fuse disconnect
is of sufficient size to handle the rated amps as
indicated on the specification label. Refer to local
codes.
3. Ensure sufficient clearances will be available as
described in the Location section on page 6.
