Two features are configured by DIP settings, which are described inside the humidifier cover.
STEP THREE: Understand the DIP Switches
STEP FOUR: Install the Transformer (Bypass Models Only)
Install transformer on the outside of a grounded metal junction box using only a 7/8 in. (22 mm) knockout hole.
Place mounting tabs into the knockout hole and firmly tighten the locking screw. Field wiring connections and
grounding means for the transformer and enclosure shall be in accordance with the National Electrical Code
(NEC) and the Canadian Electrical Code (CEC). Connect wires to the 120V side of the transformer.
For HE150 and HE250, the 15V transformer must provide constant power to the 24V IN terminals.
STEP FIVE: Wiring the Humidifier
Use a wiring diagram from the following pages that matches your equipment.
When wiring is complete, run the wires coming out of the humidifier into the wiring clip on the bottom of the
humidifier.
