Start-up checklist
Your humidification system may not have all of the options listed
below. If an item does not apply to your system, skip to the next
item and continue the process.
☐ Before you start, read this manual and other information sent
with your humidifier.
☐ Verify that the field wiring is done per the instructions in this
manual and per the unit wiring diagram.
☐ Your humidifier uses cold potable or softened water. Do not use
water treated by reverse osmosis (RO) or deionization (DI).
☐ Confirm that all wiring is correct per the wiring diagram.
☐ Confirm that proper grounding and an approved earth ground
are provided.
☐ Turn water supply on and confirm that the drain valve is closed.
☐ Turn power on and confirm that the display is illuminated.
☐ Confirm that the airflow switch is closed.
☐ Confirm that the high limit humidistat input is closed or that the
variable air volume (VAV) control system high limit transmitter
is connected.
☐ If airflow switch or high limit humidistat is not included, jumper
H-H terminals unless on/off humidistat is installed.
☐ With sufficient water in the steam cylinder, the airflow switch
closed, the high limit humidistat closed, the door interlock safety
switch closed, and a call for humidity, verify that the heat outputs
are activated.
☐ If you experience difficulties, have the above information
available with the model and serial number of the humidifier
and firmware version and call DRI-STEEM for assistance.
