Humidifier Configuration

The HM700 is configured at the factory to operate under most 

conditions without the need to change its configuration.

NOTE: Because the humidifier is factory configured for 

optimal performance, Honeywell strongly 

discourages changes to the jumpers or the 

potentiometer; doing so will void the warranty 

and could damage the humidifier. Contact 

Honeywell Customer Care for further 

information.
