— Wrench
— Pliers
— Shut-off water valve
— Water line (LDPE or Copper)

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.
Before Installation
1. Ensure that available voltage and phase 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 5.
4. Ensure steam lines can be routed to duct distributor as
described in Steam Lines and Condensate Return
Instructions on page 8.
