WARNING
Read all warnings and instructions
This page provides important safety instructions; it is intended to supplement — not replace — the humidifier's Installation,
Operation, and Maintenance Manual (IOM). Read the IOM that was provided with the humidifier before performing service or
maintenance procedures on any part of the system. Failure to follow all warnings and instructions could produce the hazardous
situations described here and in the IOM, resulting in property damage, personal injury, or death.
If the IOM is missing, go to http://www.dristeem.com/ds_lit.jsp to download a replacement.

Hot surfaces and hot water
Steam humidification systems have extremely hot surfaces, and water in tanks, electrode cylinders, steam pipes, and dispersion
assemblies can be as hot as 212 °F (100 °C). To avoid severe burns, allow the entire humidification system to cool.
Follow the cool-down procedure in the humidifier's IOM before performing service or maintenance procedures on any part of the
system.

Shut down the energy source
Before performing service or maintenance procedures on any part of the humidification system, verify that all energy sources
are off. Energy sources can be electricity, gas, steam, or hot liquid. Failure to shut down the energy source could result in carbon
monoxide poisoning, fire, explosion, electrical shock, and other hazardous conditions. These hazardous conditions could cause
property damage, personal injury, or death.
Contact with energized circuits can cause property damage, severe personal injury or death as a result of electrical shock or fire.
Do not remove the shroud/cover, electrical panel cover/door, access panels, or heater terminal cover until electrical power is
disconnected.
Follow the shutdown procedure in the humidifier's IOM before performing service or maintenance procedures on any part of the
system.
