Installation
Humidifier wiring
Control component placement
Follow the guidelines on Page 22
for placing humidistats,
transmitters, and airflow proving switches.
Connection instructions
Before connecting power, refer to the wiring diagram or the data
plate on the outside of the cabinet for wire sizing amperage.
For control signal wiring from a humidistat, transmitter, or signal
by others, see the wiring diagrams shipped inside the humidifier.
See “Step 1 – Field wiring” in the Vapor-logic4 Installation and
Operation Manual for detailed instructions on the following:
• Control input wiring:
See the “Control input” section.
• Duct airflow proving switch and duct high limit humidistat
wiring (recommended optional devices):
See the following sections:
“Airflow proving switch” and
“Duct high limit switch or transmitter”
• Remote signal wiring:
See the following sections:
“Programmable triac” and
“Programmable relay (dry contact)”
WARNING
Excessive moisture hazard
DRI-STEEM strongly recommends installing
a duct airflow proving switch and a duct
high limit humidistat. These devices
prevent a humidifier from making steam
when there is low airflow in the duct or
when the RH level in the duct is too high.
Failure to install these devices can result
in excessive moisture in the duct, which
can cause bacteria and mold growth or
dripping through the duct.

WARNING
Electric shock hazard
Only qualified electrical personnel
should perform field wiring installation
procedures. Improper wiring or contact
with energized circuits may cause property
damage, severe personal injury, or death
as a result of electric shock and/or fire.
